Hi I am trying to compile numpy with gcc 4.7.1 and I am having the following issue.

"RuntimeError: Broken toolchain: cannot link a simple C program"

Do you have Python development headers installed? Usually a separate package called python-dev on linux. If so, can you compile with an older gcc? Ralf

I noticed that I need to pass the flag '-fno-use-linker-plugin' to be able to compile it. However, even though I did pass it by exporting the CFLAGS, it does not work. I guess that numpy do not use the CFLAGS for its internal extensions. How can I pass that option to it?
