 Posted: Sun Dec 12, 2004 5:14 pm Post subject: Library build error relocation/fPIC? |
 |
|
Hi there,
As part of my application I distribute a statically linked library. However, when I compile the library on my new A64 box I get:
/usr/lib/gcc/x86_64-pc-linux-gnu/3.4.3/../../../../x86_64-pc-linux-gnu/bin/ld: gtkscintilla.o: relocation R_X86_64_32 can not be used when making a shared object; recompile with -fPIC
gtkscintilla.o: could not read symbols: Bad value
Can anyone help me with what this means and what I have to do to make the build 32/64 bit clean?
Thanks,
Andy

Your error message gives you the solution to your problem "recompile with -fPIC". i.e add -fPIC to you CFLAGS when compileing this shared library. According to the gcc man page:
| Quote: | -fPIC
If supported for the target machine, emit position-independent code,
suitable for dynamic linking and avoiding any limit on the size of
the global offset table. This option makes a difference on the m68k
and the SPARC. |
i.e you need to compile shared libs with -fPIC on amd64. |

Doh! Thanks, I was adding it to the LDFLAGS (thinking it was an error from the linker). Teach me to try and work on a Sunday 
Are there any documents on how to port applications (GTK ideally) to AMD64?
