preprocessed source requested by error output
Hi , I have run into an error whose output requested a full bug report which I
am attempting to do following the various guidelines (short of installing
another compiler. ) I am unsure if this repeats some other reports of
'unrecognizable insn', my apologies.
Error was:
gcc ccv_memory.c -o ccv_memory.o -c -O3 -ffast-math -Wall -Wextra -msse2 -D
HAVE_CBLAS -D HAVE_LIBPNG -D HAVE_LIBJPEG -D HAVE_AVCODEC -D HAVE_AVFORMAT -D

I apologize in advance if this is known or due to my own ignorance; I was
unable to find this on the list of known / common bugs/problems. The -fPIC and
-shared and -mcmodel=large flags were all attempts to fix the error "relocation
R_X86_64_32S against `.rodata' can not be used when making a shared object;
recompile with -fPIC" (I am trying to build this code into a .so library).
