[Please see #31 for a solution]

Hi,

I am trying to build the motion-effect in voidlinux which has similar directory-structure like ubuntu.

There is a confusion about some of the flags described to compile and build with cmake.

cmake -DLIBOBS_INCLUDE_DIR="<libobs path>" -DCMAKE_INSTALL_PREFIX=/usr ..

1st Try

Directory structure: http://ix.io/2x1y

I have downloaded the obs-studio master in the same directory which holds motion-effect plugin. The directory structure looks like in http://ix.io/2x1y.

When I tried to compile, it gives an error:

$
cmake -DLIBOBS_LIB="/usr/share/obs/" -DLIBOBS_INCLUDE_DIR="../obs-studio/cmake/external/" -DCMAKE_INSTALL_PREFIX=/usr ..

-- Configuring incomplete, errors occurred!

2nd Try

Directory structure: http://ix.io/2x1A

Alternatively, I have moved the obs-studio source repo inside the motion-effect source directory as appeared in http://ix.io/2x1A, but the error remained the same.

When checked in command line, the reportedly 'missing' file ObsPluginHelpers.cmake do exist!?

$ find ./motion-effect/obs-studio/cmake/external/* -iname ObsPluginHelpers.cmake
./motion-effect/obs-studio/cmake/external/ObsPluginHelpers.cmake

3rd Try

Directory structure: http://ix.io/2x1A

In pursuant to #23 (comment), I even tried without success:

$
cmake -DLIBOBS_LIB="/usr/share/obs/" -DLIBOBS_INCLUDE_DIR="/usr/share/obs" -DLibObs_DIR="../obs-studio/cmake/external/" -DCMAKE_INSTALL_PREFIX=/usr ..

See also "/home/zenny/Downloads/obs/motion-effect-build/motion-effect/build/CMakeFiles/CMakeOutput.log".

I have also changed to -DLIBOBS_INCLUDE_DIR="../obs-studio/" in all three tries, but with the same error output!

Error Log

Relevant CMakeOutput.log is posted in http://ix.io/2x1E.

Any clue on what exactly should be the defined against LIBOBS_LIB and LIBOBS_INCLUDE_DIR in linux? Thanks in advance.

Cheers and stay safe,

4th Try

In line with the StreamFX build instructions, I have also tried with the following command without success:

$  cmake -H. -B"build/flux" -G"Ninja" -DOBS_DOWNLOAD=ON -DCMAKE_PACKAGE_NAME=motion-effect -DCMAKE_PACKAGE_PREFIX="build/package" -DCMAKE_INSTALL_PREFIX="build/distrib" -DCMAKE_CXX_COMPILER=g++ -DCMAKE_C_COMPILER=gcc -DCMAKE_SKIP_RPATH="YES" -DLIBOBS_INCLUDE_DIR="./obs-studio/"
