RE: Error when compiling static openSSL (libcrypto.a) into shared library

[Frank E. Gruman]

I have since also reproduced this error when compiliing with openssl-1.0.0e (LATEST).

 

Is there no one out there having challenges with this sort of compile?  Alternatives for getting this working on a 64-bit system?

 

Regards,

Frank

Subject: Error when compiling static openSSL (libcrypto.a) into shared library

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

Are you sure that all of your stuff is building with –fPIC?

 

I was having a similar problem, but once I made sure everything compiled with –fPIC, my errors went away.
