I'm not sure if this is a bug or not.. I get a build failure for sci-mathematics/snns when its trying to link against libfl.a (which is a part of sys-devel/flex). The failure is:
| Code: | creating build/temp.linux-x86_64-2.4

x86_64-pc-linux-gnu-gcc -pthread -fno-strict-aliasing -DNDEBUG -march=athlon64 -pipe -O2 -fPIC -I../kernel/sources -I/usr/include/python2.4 -c snns/krui.c -o build/temp.linux-x86_64-2.4/snns/krui.o

The reason is because I don't have -fPIC in my CFLAGS but all the files in the snns package are automatically built with -fPIC. I was reading through some of the threads and it said fPIC would lead to slower binaries but libraries should be built with -fPIC. I was wondering, should libfl.a in the flex package always be built with -fPIC or should the files snns package not be forced to be built with -fPIC? |

I have the same problem with app-misc/glimpse. Worked around it by adding -fPIC to CFLAGS, reemerging flex, removing -fPIC and proceeding. Emerge barked on me about -fPIC in CFLAGS though, so I've no idea whether it might lead to more breakage.

yea. I suppose I should just submit it as a bug and see what the devs have to say about it. |
