Error when building ABY framework

[Cestlaviez]

When I tried to build the ABY framework, these errors occurred.

ABY/src/abycore/sharing/boolsharing.cpp:20:22: fatal error: filesystem: No such file or directory
compilation terminated.
src/abycore/CMakeFiles/aby.dir/build.make:192: recipe for target 'src/abycore/CMakeFiles/aby.dir/sharing/boolsharing.cpp.o' failed
make[2]: *** [src/abycore/CMakeFiles/aby.dir/sharing/boolsharing.cpp.o] Error 1
CMakeFiles/Makefile2:260: recipe for target 'src/abycore/CMakeFiles/aby.dir/all' failed
make[1]: *** [src/abycore/CMakeFiles/aby.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

Then I tried to change filesystem into experimental/filesystem , but it didn't work.

Hi,
if you use the experimental/filesystem header, then you need to use the std::experimental::filesystem namespace as well (iirc).
The C++17 filesystem library (non-experimental) should be available with libstd++ 8 or newer (shipped with GCC 8) or libc++ 7 or newer.

I have used the std::experimental::filesystem, it didn't work.
But after I upgraded GCC to version 8, it succeeded.
Thanks.

Ok, I have updated the README that a recent GCC version is required.
