Building git project in linux

I am trying to build project in below path and following the procedure provided in below link but getting error.


Hello @prashant.s,

According to the README documentation in that GitHub repository, you need to create a build directory and then call the script from that directory within firmware-himax-we-i-plus:

$ mkdir build-gnu
$ cd build-gnu
$ cmake .. -DCMAKE_TOOLCHAIN_FILE=toolchain.gnu.cmake

Build directory:
Inside build-gnu folder is below

Inside firmware-himax-we-i-plus folder

Running cmake … -DCMAKE_TOOLCHAIN_FILE=toolchain.gnu.cmake command

but getting error


The build-gnu directory needs to be inside the firmware directory: firmware-himax-we-i-plus/build-gnu

You need to run the cmake command from inside the build-gnu directory as well:

cd build-gnu
cmake .. -DCMAKE_TOOLCHAIN_FILE=toolchain.gnu.cmake

Hello @prashant.s,

This is because you have created a CMakeCache.txt file in multiple places within your project by running the cmake command not in the build-gnu directory. Please go ahead and delete this project firmware-himax-we-i-plus and start a fresh one by cloning / downloading from the GitHub repo again.

Then please follow the README instructions exactly to build from the build-gnu directory using the cmake command.



Please make sure you install the software prerequisites described here:

I am building in linux machine so need only ARC GNU Toolchain

edge impulse is also installed and getting video streaming in edge impulse studio.
