Hello All, I'm a newbie to this mailing list. I am trying to build static boost libraries and link to my libraries. I used ./bjam debug link=static cxxflags="-std=c++0x" stage to build the boost libraries. When I build my libraries (shared or static) with linking to boost libraries, I get the following error: libboost_regex.a(instances.o): relocation R_X86_64_32 against `.bss' can not be used when making a shared object; recompile with -fPIC libboost_regex.a: could not read symbols: Bad value Then I tried adding -fPIC while building my boost libraries. Didn't help. Any suggestions. Thank you Kotesh
If you want to compile something that will be in a shared library, you need to recompile Boost libraries with -fPIC. When switching to static libraries, this flag is not added. Static libraries don't need to be linked against Boost BTW. Cheers, Matthieu 2014-03-03 20:35 GMT+00:00 Koteswara Rao Ruvva <ruvva@yahoo.com>:

Thanks Matthieu. As I mentioned I used the -fPIC option while building the static boost libraries as shown below: ./bjam debug link=static cxxflags="-fPIC -std=c++0x" stage But didn't help. Still getting the same error message. BTW, following is my system info, if that helps: Linux lily-linux 3.5.0-46-generic #70~precise1-Ubuntu SMP Thu Jan 9 23:55:12 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux Kotesh ________________________________ From: Matthieu Brucher <matthieu.brucher@gmail.com> To: boost-users@lists.boost.org Sent: Monday, March 3, 2014 1:21 PM Subject: Re: [Boost-users] relocation R_X86_64_32 against If you want to compile something that will be in a shared library, you need to recompile Boost libraries with -fPIC.

You need to use the -fPIC option when building your code also. Any object files that are to be placed into a static library for the x86_64 architecture must be compiled using position-independent code. Jason

That's not exactly true. Only code that can end up in a _shared_ library (i.e. source code of a shared library or a static library that is linked against a shared library) needs to be compiled with this option.

Thanks. I swapped the static/shared library type in my description before. I concur with your explanation. Jason
That worked. Thank you Matthieu & Jason. ________________________________ From: Matthieu Brucher <matthieu.brucher@gmail.com> To: boost-users@lists.boost.org Sent: Monday, March 3, 2014 4:00 PM Subject: Re: [Boost-users] relocation R_X86_64_32 against
