Static libraries were always built without -fPIC and I don't think there was any change in this area. Ok, I wasn't sure either, but I don't remember setting it with Boost 1.37.
The environment is Linux with GCC 4.3.2, on x64.
Any chance you just recently upgraded to an x64 system? On x64, it's all or nothing, you cannot mix PIC and non-PIC code.
No, it was x64 before as well, same system. And I'm sure I used -fPIC on all of my code.
Thinking about this, shouldn't be -fPIC enabled on Linux/x64 by default?
I am not sure -- if gcc does not enable -fPIC in this configuration, why Boost.Build should second-guess it?
Otherwise, you can't link Boost
This is not an issue specific to Boost.
statically into a .so without changing the build parameters. Or are there any negative effects by enabling -fPIC?
-fPIC generates slower code. I am not aware of up-to-date data on how much slower. - Volodya
