Hello all,
I am trying to compile a static libcrypto.a into a shared library. Every time
I do this I receive the following error:
[100%] Building CXX object
CMakeFiles/testprovider.dir/soapTestServiceGatewayProxy.cpp.o
Linking CXX shared library libtestprovider.so
/usr/bin/ld:
/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libcrypto.a(x86_64cpuid.o):
relocation R_X86_64_PC32 against `OPENSSL_cpuid_setup' can not be used when
making a shared object; recompile with -fPIC
Here are the environments I have tested this with:
CentOS 5 (x64)
- gcc 4.1.2-51.el5
- openssl-0.9.8r
- configured with ./config -fPIC
RHEL 5.5 (x64)
- gcc 4.1.2-15.el5
- openssl-0.9.8r
- configured with ./config -fPIC
I have tried passing -Wl,-Bsymbolic to the compiler when linking my shared
library to libcrypto.a and had no luck. I did try to compile after passing the
no-asm flag and it allowed me to link, but I have grave concerns about the
performance implications. The library is very performance critical. As it is
now, we can test functionality using a shared libcrypto.so, but this is not
ideal for production testing if we can avoid it.
Any thoughts? I had found some information out here -
http://rt.openssl.org/Ticket/Display.html?id=2466&user=guest&pass=guest . Does
anyone know in which release the formal patch noted in that link was included?
Regards,
Frank
