Compile OpenSSL with the 'shared' option?

Question

On CentOS 5.4, OpenSSL compiles fine without 'shared' option. But when I passed that option the compilation fails with:

/usr/bin/ld: libcrypto.a(x86_64-gcc.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC

When I try: ./config shared CFLAGS=-fPIC that doesn't work.

What can I do to get OpenSSL to compile with the 'shared' option?

Thanks

Answer 1

Same problem here, BUT usually Makefiles will consider environment variables for compiler or linker options.

So, if you place the -fPIC option before calling the configure script, it should take care of it. You can do it with:

CFLAGS=-fPIC ./config shared --prefix=/your/path 

or

export CFLAGS=-fPIC ./config shared --prefix=/your/path 

It worked for me.

Answer 2

There is an option -fXXX that you can pass to config so you can do it with:

./config -fPIC shared
