(In reply to Toralf Förster from comment #0) > In file included from ffitcontour.cpp:51:0: > /usr/include/stdlib.h:722:12: error: expected unqualified-id before ‘int’ > extern int abs (int __x) __THROW __attribute__ ((__const__)) __wur; > ^ > /usr/include/stdlib.h:722:12: error: expected ‘)’ before ‘int’ I see the error is in /usr/include/stdlib.h, not in gle :-) I've just successfully re-compiled gle with gcc-6.4.0. Looks like a problem with gcc-7.2.0.
I have the same problem with gcc-6.4.0 too. I think this is a problem with new profile default/linux/amd64/17.0 this profile enables C++14 I can compile gle if I do this changes! 1.) eselect gcc set gcc-6.4.0 2.) change CXXFLAGS ; CXXFLAGS="-std=c+11" now gle compiles.
I believe this is caused by including headers in the wrong order. The file "src/gle/fitcf.h" defines abs as a macro. The file "src/gle/surface/ffitcontour.cpp" includes the headers in the wrong order, so the macro tries to be applied to the stdlib.h header. Commenting out abs, min, and max from fitcf.h and changing the order of the headers in ffitcontour.cpp (as is done on macos) allows this to compile.
