Subject: [parisc-linux] Problem with weak symbols
Date: Tue, 07 Jan 2003 14:05:25 +0100 [thread overview]
Message-ID: <3E1AD095.FA5CF165@web.de> (raw)
Hi,
I have a problem with weak symbols on parisc. If I use the following
small program, the result should be always (nil), but it isn=B4t:
> cat weak.c
#include <stdio.h>
#include <ctype.h>
=
asm (".weak linux_bla");
asm (".weak linux_foo");
=
extern const char * linux_bla;
extern const int linux_foo[];
=
int
main ()
{
printf("linux_bla: %p\n", &linux_bla);
printf("linux_foo: %p\n", &linux_foo);
return 0;
}
> ./weak
linux_bla: 0x205f0
linux_foo: (nil)
The main difference in compiling seems to be the different relocation
type for both symbols:
> readelf -r weak.o
=
Relocation section '.rela.text' at offset 0x410 contains 10 entries:
Offset Info Type Symbol's Value Symbol's Name =

linux_foo + 0
00000038 00c0c R_PARISC_PCREL17F 00000000 =
printf + 0
I am currently using gcc version 3.2.1, binutils version 2.13.90.0.16
20021126, glibc version 2.3.1, but I had this problem already with gcc
3.0.4 and all compilers inbetween. Is there a possibility to work around
this?
