Compilation fails with CMake version 3.14.0 and g++ version 4.8.5 about eddl HOT 9 CLOSED

Most flags are automatic or have default values:

• GPU falling back to CPU
• OpenMP (if available, it'll be on)
• SHARED_LIB (default)
• PREFIX_INSTAL...
• etc
  (You can change them if you want, but is better to let cmake choose their values for you)

But other flags are too agressive and need specific requirements. So I recommend not to use them: BUILD_HPC, MKL
By default they are disabled for compatibility purposes.

More:

• BUILD_TESTS should be off (i need to update the tests)

I have tried calling cmake with only these parameters: -DBUILD_TARGET=CPU -DBUILD_SHARED_LIB=ON -DBUILD_PROTOBUF=OFF -DBUILD_EXAMPLES=ON -DCMAKE_INSTALL_PREFIX=/home/oliveri/oliveri/eddl and unfortunately make fails with the same errors.
Here is the output of CMake:

rm -rf *
and cmake again

Already done. I actually delete the whole repository and reclone it at each try, so it's unfortunately not as simple as cleaning the build folder.

Try using a more recent version of the GNU compiler (or another). You currently use GNU 4.8.5, so try with g++-9 or clang (for instance)

ok! seems that cold be the compiler version.

@Andrea-Oliveri any news?

Unfortunately I don't have sudo rights to update the compiler on the CentOS, so the whole process od trying a more recent compiler version is going to take a while. However, knowing that on the Ubuntu machine with a more recent compiler the build process works flawlessly, I think you are right and eddl is just incompatible with too old gcc/g++ versions.
Thank you for your support.

Okay, so I'm gonna close this issue.

Btw, it is possible change the compiler using this cmake flag: -DCMAKE_CXX_COMPILER=/path/to/c++compiler
