Fatal error libusb h no such file or directory

Trying to install rtl-sdr (through git clone git://git.osmocom.org/rtl-sdr.git) thanks to the instructions here but can’t go further than make in the first sequence of instructions:

cd rtl-sdr/
mkdir build
cd build
cmake ../
make

At my first try I got the following error:

/rtl-sdr/src/librtlsdr.c:30:10: fatal error: libusb.h: No such file or directory

After locating this file:

/usr/include$ sudo locate libusb.h
/usr/include/libusb-1.0/libusb.h

I tried to replace the original #include <libusb.h> with #include <libusb-1.0/libusb.h> (as suggested here and here), which led to a different failure:

Note that this suggestion seems to be associated with a gcc compile option / link --cflags libusb-1.0 or -lusb-1.0 (cf. here and here) that I don’t know where to find (since I’m using make, without being used to it).

I also tried to replace the original #include <libusb.h> with #include <usb.h> (as seen here) which led to:

/rtl-sdr/src/librtlsdr.c:97:2: error: unknown type name ‘libusb_context’

FYI libusb-1.0-0-dev and libusb-dev are already installed (as suggested here, I tried, eventhough I guess I already had it installed…):

/usr/include$ sudo apt install libusb-1.0-0-dev
libusb-1.0-0-dev is already the newest version (2:1.0.21-2).

~$ sudo apt install libusb-dev
libusb-dev is already the newest version (2:0.1.12-31).

And already installed rtl-sdr using apt:

sudo apt-get install rtl-sdr
rtl-sdr is already the newest version (0.5.3-13).

About my system: Linux version 5.4.0-58-generic gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04). This install aims at being able to use a DVB-T dongle with GNU Radio, which requires this rtl-sdr install.

EDIT: after @Tsyvarev answer

1. installed pkg-config with sudo apt install pkg-config
2. removed the first repository resulting from the initial git clone, new clean
   git clone, new /build etc and then make, which worked !

Removing the old repository clone & re-creating a clean /build was necessary, since trying to launch make in the old /build even after the install of pkg-config didn’t work. Note that this implies that no change was needed on the #include <libusb.h> code line in src/librtlsdr.c.

As a side note, for those of you who end up here because they’re trying to install the «RTL-SDR Source» block for GNU Radio, I suspect my problem was actually that I hadn’t installed gr-osmosdr with sudo apt install gr-osmosdr after installing rtl-sdr with a simple sudo apt-get install rtl-sdr.

(Applicable to #Ubuntu, #Debian, #Raspbian in my case)
*1st, I followed and apply the steps above of awesome advice and for the most part it got me to the part that I just figured out below. So hopefully the advice aboe + mine equals finally 1 place where all the solutions live and not scattered all over the interwebs.
*Then, made sure I started the steps in the correct directories. So don’t start at /home if you’re supposed to have a specific path per some instructions you already have.
*Test starting at /root, and another test at /yourusername
*if you are making a dir «/src» use the Tilde symbol before the dir name. Damn, I can’t place it in this comment or it does a strike-thru the following words, but the little squiggly symbol under the ESC key if you press Shift). Sounds stupid but fixed one of the errors.

Call me crazy, and I’m not a coder, or linux buff, just basic, so I used the help of the GUI.
In my case, getting this to Build and Install and process would fail at multiple stages like Errors above, and at some tar.bz2 extract stages. This is what I did via Terminal and then GUI as I encountered errors:

1 — a few errors at first were simple syntax errors (facepalm complete), such as spelling «libusb» as «lisusb». Again, 🤦 initiated multiple times, but CHECK THIS FIRST.
2 — these are relevant to the above comments, MOST of the issues were DIR issues.
(ie The ones related to the «make» process, a lot of times were because the DIR those files -(ie configure, makefile, the ‘tar.bz2 or tar.gz’ files, etc.,) — were in the wrong directories.
*To fix this, I had to first figure out where they extracted, why they extracted in wrong directories in the first places, then get them into the correct DIRs (/src, /var, /build, /libusb /etc) I did this part via the GUI. as I mentioned.
It was weird cause I was running all the WGET and TAR steps inside the directories some of these online instructions were telling me, like within ‘SRC’ or ‘BUILD’ and so on.

3 — There was a point in the Steps, where you have to ‘cd’ into the DIR ‘libusb vxX.X.X’ and perform commands within it like the MAKE and CONFIGURE process, HOWEVER, you get the errors either:
‘No such Directory’ or another one (can’t and don’t want to remember) with 4 or 5 lines related to Error: Child Directory Something Or Rather and with some numbers, along with the error above in those steps.
*To fix that one, basically it was that the ‘libusb’ file was just that, a FILE. How this happened or why? IDK. The point is I fixed it by old-fashion common sense, ‘MKDIR’. Now that I made a directory, of course it was empty. ##oh, make sure the syntax and version of ‘libusb’ is the version you are installing+downloaded (or ‘wget’ing) when you create the directory manually##
*So basically create the folder you are getting stuck on and errors, then place all the files that are supposed to be in there- I did this using BOTH terminal and GUI.
** Files like «libusb-vX.X» & «libfreekenect» or the distro files. Jus dump them in this new directory you manually made.
**Another error was extracting, «No Such File or DIR» — just use the GUI and double check everything.

4- Missing files or DIRs — Copying and Pasting files from the extracted folder using the GUI into the directories that were either empty, didn’t exist, or already had files in it but were related to where I was getting stuck, is how I fixed a lot of these frustrating errors sometimes.
*Then in each DIR I dropped files in or did some of these things I mentioned, for good measure:

• I would again do perform a WGET

*sudo apt-get- update (and upgrade) always
*double check everything as you go along ‘ls -a’ and see if things are getting more logical and files are there that are supposed to be (or again, use the GUI)

#Basically I loaded, re-extracted, and packed the sh*t out of everything; didn’t care at this point, just Copy/Pasted Everything starting at the ‘/src’ all the way through ‘/libusb%/build’, even if certain things weren’t supposed to be in there, or had no purpose (as long as it would not trigger adverse effects.)#
The majority of the files I was duplicating and loading every directory with were GENERIC files anyway that came with the distros and releases I was trying to get installed. So I didn’t care, just use common sense (ie You cannot put a «build» directory within itself)

• If you are copy/pasting using the GUI, Select All the files from the parent DIRs and starts pasting them in the next directory, and so on.
  #I know this might be messy and not the best method, but hey guess what, this is the only thing that worked out off all the advice and sites I found that did nothing ( or a little good but not the ultimate goal).#

Finally started seeing the files that were supposed to be these and solved the ‘no such file’ and ‘makelist’ or no make file errors.

One last thing, since I was Copy/Pasting contents of the DIRS that did have a MAKEFILE and CONFIGURE files, into the DIRs that did not or were acting wonky, launching the config file (GUI) or command (terminal) needs to be done carefully.
For example, make sure if you are taking, say, the CONFIGURE file from a parent directory, that it is still related to the distro or process versions you are trying to install.
GOOD — taking the CONFIGURE file from DIRs in ‘libusb’ and pasting to sub DIRs of linusb.
BAD — taking a CONFIGURE file from DIRs in ‘libusb’ and pasting them into DIRS of ‘freekenct’.

cmake, build, -xjf tar.bz2, and all the steps related to these errors (a few above my comment and my own) all were fixed, and things just started working how they were supposed to after this.

SUMMARY:
-if you are missing a directory, MKDIR and use common sense determining what files are supposed to be in there, and find them and copy them in there.

• if you are taking files from a parent dir to paste them in a sub dir, make sure you use COPY and not CUT. I know that you’ll have duplicates and a bunch of files in DIRs you won’t need, but who cares, it fixes the issue and whatever it doesn’t need it just won’t use. Space-wise, it doesn’t take up that much.
  -sudo where you get permission errors
  -sudo chmod 777 if you get more permission errors
  -reboot at least once and start all over if you hit a wall
  -use the GUI and extract in either «test» folders or the actual directories (I’m no going to figure out the root cause, so I will be using ‘test’ folders now and doing one thing at a time and reversing that if it didn’t work until I find what does make it work). For now, just use the actual directories- worked for me.
• and when you get passed your errors and are at steps where you are actually trying to start communicating via usb or testing the cam/device

If somebody can consolidate this into one gold nugget of an article or solution, please do so.
Sorry for long post. I’m thorough, and also come across of posts that people offer solutions but are vague or say things like «try this» out of context and without saying at exactly what steps of before and after what command. Lol.
Hope this helps at least 1 person.

Приветствую!

Ребята, подскажите пожалуйста, уже несколько дней не могу решить проблему с компиляцией программы, которая использует libusb.

Предыстория. Начал разбираться с кросс-компиляцией по этому мануалу: http://telecnatron.com/articles/Cros…nWRT-On-Linux/

Вроде бы всё неплохо, hello world скомпилировалось отлично (опустим танцы с бубном по поводу установки среды для кросс-компиляции, та ещё процедура для меня), на роутере запустилось. Дальше у меня была задача скомпилировать программу dcled (http://www.last-outpost.com/~malakai/dcled/), чтобы попробовать вывести какие-то надписи на подключаемому по USB led-бэджику (в будущем хочу сделать его управляемым по wifi). Скачал исходники программы, распаковал. И тут засада…

Сначало пробовал сделать всё тоже самое, что и с классическим примером:

# Set up paths and environment for cross compiling for openwrt
export STAGING_DIR=/usr/local/crosscompile/openwrt/staging_dir
export TOOLCHAIN_DIR=$STAGING_DIR/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2
export LDCFLAGS=$TOOLCHAIN_DIR/usr/lib
export LD_LIBRARY_PATH=$TOOLCHAIN_DIR/usr/lib
export PATH=$TOOLCHAIN_DIR/bin:$PATH
mips-openwrt-linux-gcc -g -lm -lusb-1.0 -o dcled dcled.c

На выходе имеем ошибку:

dcled.c:30:20: fatal error: libusb.h: No such file or directory
 #include <libusb.h>
                    ^
compilation terminated.

Ок… пишут, что можно использовать стандартный make-файл с такими параметрами:

# Set up paths and environment for cross compiling for openwrt
export STAGING_DIR=/usr/local/crosscompile/openwrt/staging_dir
export TOOLCHAIN_DIR=$STAGING_DIR/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2
export LDCFLAGS=$TOOLCHAIN_DIR/usr/lib
export LD_LIBRARY_PATH=$TOOLCHAIN_DIR/usr/lib
export PATH=$TOOLCHAIN_DIR/bin:$PATH
make CC=mips-openwrt-linux-uclibc-gcc LD=mips-openwrt-linux-uclibc-ld

на выходе:

mips-openwrt-linux-uclibc-gcc dcled.o -o dcled -g -lm -lusb-1.0
/usr/local/crosscompile/openwrt/staging_dir/toolchain-mips_34kc_gcc-4.8-linaro_uClibc-0.9.33.2/lib/gcc/mips-openwrt-linux-uclibc/4.8.3/../../../../mips-openwrt-linux-uclibc/bin/ld: cannot find -lusb-1.0
collect2: error: ld returned 1 exit status
make: *** [dcled] Error 1

Перепробовал уже наверное миллион комбинаций и, честно говоря, мозг закипает.

Для справки результат выполнения «locate libusb.h»

/usr/include/libusb-1.0/libusb.h
/usr/local/crosscompile/openwrt/build_dir/target-mips_34kc_uClibc-0.9.33.2/libusb-1.0.9/ipkg-install/usr/include/libusb-1.0/libusb.h

/usr/local/crosscompile/openwrt/staging_dir/target-mips_34kc_uClibc-0.9.33.2/usr/include/libusb-1.0/libusb.h

Помогите, а то с ума сойду
Как вариант, может кто-нибудь может скомпилировать мне эту чёртову программу, т.к. я не уверен, что она в итоге у меня заработает и всё может оказаться зря…

ЗАРАНЕЕ СПАСИБО!!!

Summary: What is ‘usb.h’?

• Is this a system specific file that should be installed with my OS?
• Is it a software specific file that should be included with the source code I’m compiling?
• Is it generically replaceable by download?
• Can I write this file from scratch?

Expansion:
Very new to Ubuntu. Working my way through installations of my desired software (GNU-RADIO and GNSS-SDR).
While trying to configure a certain piece of hardware (SiGe GN3S Sampler v2 usb device) as an RF-Front End for the software, I received the following errors:

dsradin@dsradin-HP-Pavilion-dv6-Notebook-PC:~/gnss-sdr/drivers/gr-gn3s/build$ make

I tried looking through the system to find the files with no joy:

dsradin@dsradin-HP-Pavilion-dv6-Notebook-PC:~/gnss-sdr/drivers/gr-gn3s/build$ whereis usb.h
usb:
dsradin@dsradin-HP-Pavilion-dv6-Notebook-PC:~/gnss-sdr/drivers/gr-gn3s/build$ whereis libusb

libusb:

The excerpt from the readme I am following with the instructions say:

• Build GN3S V2 Custom firmware and driver (OPTIONAL)

Go to GR-GN3S root directory, compile and install the driver:
(read the drivers/gr-gn3s/README for more information)

$ cd gnss-sdr/drivers/gr-gn3s
$ cd build
$ cmake ../
$ make
$ sudo make install
$ sudo ldconfig

Set the environment variable GN3S_DRIVER=1 in order to enable the GN3S_Signal_Source in GNSS-SDR (OPTIONAL)

$ export GN3S_DRIVER=1

In order to gain access to USB ports, gnss-sdr should be used as root.
In addition, the driver requires access to the GN3S firmware binary file.
It should be available in the same path where the application is called.
GNSS-SDR comes with a pre-compiled custom GN3S firmware available at gnss-sdr/firmware/GN3S_v2/bin/gn3s_firmware.ihx.
Please copy this file to the application path. The GNSS-SDR default path is gnss-sdr/install

(in order to disable the GN3S_Signal_Source compilation, you should remove the GN3S_DRIVER variable and build again GNSS-SDR)

I have uninstalled all packages related and re-cloned the GIT repositories that house all the relevant source codes and scoured the internet but without more information about what exactly I’m looking for I’m stuck.

Any suggestions??
Thank you for your help!
