Created attachment 466358 [details, diff] patch file add missing #include unistd.h Tarball from Intel does not compile due to missing include unistd.h in the ATVersion.cpp source file. Created a user patch to fix missing include file declaration. [attachment] I used the hook /etc/portage/bashrc to force my user patch to be applied.
better later than never, thanks, added the patch and fixed the ebuild (did not work with later GCC).
