I'm unable to compile anything in my linux pc. I have no idea why, probably I've installed some package and made a mess. I've uninstalled and reinstalled gcc and other packages, but no good news.. still this problem.

This is the message:

/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-
linux/bin/ld: /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/crt1.o: unrecognized relocation (0x29) in section `.text'

Any idea of what does it mean and how to fix this problem?

cheers

For anyone else that encounters this issue: I think @gabib44's problem was using a older version of ld to link a library that had been built with a newer version.

"unrecognized relocation" occurs when the relocation type is greater than the greatest known relocation type in your version of ld. 0x2a (R_X86_64_REX_GOTPCRELX) is presently the relocation type with the greatest value; I guess @gabib44's ld was old enough to not know about the relocation type before that one (0x29, R_X86_64_GOTPCRELX).

I had this problem myself when I was building a library with binutils v2.26 (which knew about relocation 0x2a) but then incorporating that library on a build machine using binutils v2.24

The fix is either to build the library that you want to link with a older version of the binutils suite, or to upgrade ld on the machine that wants to link that library.
