Right, it seems that it was build with it. The linker would probably have complained about a different symbol in case it wasn't. It says that x86_64cpuid.o has a R_X86_64_PC32 relocation. Since it's actually a assembler file, it means the assembler isn't PIC. Looking at the static library (with or without -fPIC) I get: Relocation section '.rela.init' at offset 0x530 contains 1 entries: Offset Info Type Sym. Value Sym. Name + Addend000000000001 000a00000002 R_X86_64_PC32 0000000000000000 OPENSSL_cpuid_setup + fffffffffffffffc In the the case with -fPIC it's the only exported symbol with a relocation that can be a problem. For a PIC version, you should change the call to: call [EMAIL PROTECTED] Then I get: Relocation section '.rela.init' at offset 0x8f0 contains 1 entries: Offset Info Type Sym. Value Sym. Name + Addend000000000001 000f00000004 R_X86_64_PLT32 0000000000000000 OPENSSL_cpuid_setup + fffffffffffffffc With that change, I can actually create a shared libcrypto.so without using -Bsymbolic. > surely wants to include copy of OpenSSL code into own .so.

A. -Bsymbolic might be able to change some relocation in others allowing you to create a shared library, but that's luck that the linker can do such an optimization. What -Bsymbolic is for is changing the order in which symbols are looked up by the dynamic linker.
