Hello,starting with GCC 4.9.0, compiler will use just slim objects files during LTO compilation. That means, no assembly output is put to object files. I noticed that libtool uses nm tools to extract symbol from object file: http://pastebin.com/RF1VubdR. Would it be possible to add -fno-lto for this check?
I think there should be added '-fno-lto' at line 14: (eval $ac_compile -fno-lto) 2>&5 What do you think about that? Thank you, Martin
