Compile OpentimelineIO ​

Here is my current environment:

  • CentOS 7
  • gcc 12.3.0
  • cmake 3.28
  • mpfr 4.2.1
  • mpc 1.3.1
  • gmp 6.3.0
  • OpenImageIO v0.15

Clone it ​

Use git to clone the GitHub repository.

git clone https://github.com/AcademySoftwareFoundation/OpenTimelineIO.git
cd OpenTimelineIO
git checkout v0.15.0

Build it ​

bash
cmake -S . -B ./build -DCMAKE_INSTALL_PREFIX=<OTIO_SOURCE_DIR>/install\
 -DCMAKE_BUILD_TYPE=Release

Compile it ​

bash
cmake --build ./build --target install

If you got error like this:

bash
In file included from <OPENTIMELINEIO_SOURCE_DIR>/src/opentime/rationalTime.cpp:4:0:
<OPENTIMELINEIO_SOURCE_DIR>/src/opentime/rationalTime.h: In function ‘constexpr double opentime::v1_0::fabs(double)’:
<OPENTIMELINEIO_SOURCE_DIR>/src/opentime/rationalTime.h:32:1: error: body of constexpr function ‘constexpr double opentime::v1_0::fabs(double)’ not a return-statement
 }
 ^
gmake[2]: *** [src/opentime/CMakeFiles/opentime.dir/rationalTime.o] Error 1
gmake[1]: *** [src/opentime/CMakeFiles/opentime.dir/all] Error 2
gmake: *** [all] Error 2

Try adding your gcc binary path to cmake command:

bash
cmake -S . -B ./build -DCMAKE_INSTALL_PREFIX=<OTIO_SOURCE_DIR>/install\
 -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_COMPILER=<GCC_ROOT_DIR>/bin/gcc
