Thanks a lot for your kinds replied Andrew,
However, when I get to X86 (whether Intel or AMD) it does not work
anymore. I can compile the files, and build the static library
libroc.a.
It works fine and I can move it from AMD to intel (not the other way
around, but I assume it is a problem with my installation). However,
when I try to build a dynamically linked library, gcc complains that
"Relocation R_X86_64_32 against 'a local symbol' can not be used
when making a share object; recompile with -fPIC"
then it tells me it can't read symbols .o because it is a bad value.
You need to compile everything that goes into a dynamically linked
library with -fPIC.
I have to admit my ignorance on compilers building, but once i
download unpack and so on the gcc compiler package, I can't
figure out in which of the hundreds of lines of the various makefiles
or configuration files I should put the -fPIC flag.
Forgive my naive question,
Lorenzo
