Could not find file "config.h"

[YuzheHao]

I downloaded the master-branch, and try to run a depth example program in Clion, then I got this error message:

librealsense-master/cmake-build-debug/third-party/libusb/libusb/core.c:23:20: fatal error: config.h: No such file or directory #include "config.h"

Before I downloading the whole master-branch, I have tried to run a program to get the distance, and it works, so I don't think my environment is not complete.
Maybe it is a rather beginner problem but I hope could get some helps here

Hi @YuzheHao
Have you tried manually running cmake .. && make? I suspect something is wrong with Clion CMake configuration, you should not be encountering this error when building from source.

[YuzheHao]

Thank you for the answering,
i tried to run cmake .. && make, and I got the following error:

CMake Error at CMakeLists.txt:5 (include):
include could not find load file:
CMake/lrs_options.cmake

CMake Error at CMakeLists.txt:6 (include):
include could not find load file:
CMake/connectivity_check.cmake

CMake Error at CMakeLists.txt:9 (if):
if given arguments:
"OR" "OR"

Unknown arguments specified
-- Configuring incomplete, errors occurred!
See also "/work/yuzhe/docs/librealsense-master/CMakeFiles/CMakeOutput.log".

Do you have any idea how could I check the cmake config of CLion?

Something is strange with the output, step by step, please try:

cd ~
git clone https://github.com/IntelRealSense/librealsense.git
cd librealsense
mkdir build
cd build
cmake ..
make

This should download and build librealsense on your machine

Install this lib for debug:
sudo apt-get install libusb-1.0-0-dev

Sorry.... I tried this line by line, and it is still telling me "lacking config.h". And this time I ran all these commands in shell rather than in CLion, which makes me confused more....

Hi everyone, I have solved this problem, thank you for your helping.
Later I will summarize the solution and post it here.

To me, running

sudo apt-get install libusb-1.0-0-dev

solved the issue

I'm getting this error during cross compile.
Is there any workaround to compile libusb without installing globally?

[monacv]

$ sudo apt-get install libusb-1.0-0-dev
didn't solve the issue for me

@monacv try cleaning the build folder and doing cmake && make again

cd ..
sudo rm -R build
mkdir build && cd build
cmake ..
make
...
