v1.1.0 compile problem with g++ 7.3.0

[jdb.w...@gmail.com]

Hi,

I tried to compile OCIO version 1.1.0 on a Debian based distro using g++ 7.3.0:

$ cat /etc/debian_version
buster/sid
$ g++ --version
g++ (Debian 7.3.0-11) 7.3.0

I get error messages related to "-Werror=deprecated-declarations".

Here is the first one:

$ cmake -D CMAKE_INSTALL_PREFIX=/usr/local/ocio ~/git/github/OpenColorIO
-- The C compiler identification is GNU 7.3.0
-- The CXX compiler identification is GNU 7.3.0
...

Any ideas how to make this work?

Thanks,

Hi Jan,

According to the gcc documentation (Warning-Options), you could disable the warning with -Wno-deprecated-declarations

Another option could be to use the installed yaml (instead of the OCIO one) with  USE_EXTERNAL_YAML
