when i finish to install multilib package i came across a big problem ! gcc (5.3) dosn't compile anything !! if i try to compile a simple "hello world" program i got:

Code:

 [marco ~]$ gcc prova.c
/usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: /usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../lib64/crti.o: unrecognized relocation (0x2a) in section `.init'
/usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: final link faild: Bad value

What gcc programs do you have installed?

Code:

ls -la /var/log/packages/gcc*

Hi drudox and welcome to this forum.

I assume that you are running Slackware64-current, as gcc 5.3 was recently included in it

@All: It 's always good to give such information.

I suggest that you first try to compile your program on a pure 64-bit Slackware current (not multilib) and see what you come up with. This could help find out if if this is a multilib related issue or not.

Also, did the same programs compile OK with the previous gcc version, pure 64-bit as multilib?

What versions of the glibc package do you have installed?

Code:

ls -la /var/log/packages/glibc*

if you pulled from some of the new rsync's you may have problems.
I would go this route.

Code:

##UPGRADE MULTI-LIB
 #!/bin/bash
# Init
FILE="/tmp/out.$$"
GREP="/bin/grep"
#....
# Make sure only root can run our script
if [ "$(id -u)" != "0" ]; then
   echo "This script must be run as root if you install regular user
   please use the assume root command " 1>&2
   exit 1
fi

# ...
cd /var/cache
lftp -c   'open http://slackware.com/~alien/multilib/ ; mirror -c -e --delete-first  current' # replace with slackware version
cd /var/cache/current # replace with slackware version
upgradepkg --reinstall --install-new *.t?z
cd /var/cache/current/slackware64-compat32  # replace with slackware version
upgradepkg --install-new *?/*.t?z

upgraded to multilib packages:

Code:

gcc-5.3.0_multilib-x86_64-2alien
gcc-g++-5.3.0_multilib-x86_64-2alien
gcc-gfortran-5.3.0_multilib-x86_64-2alien
gcc-gnat-5.3.0_multilib-x86_64-2alien
gcc-go-5.3.0_multilib-x86_64-2alien
gcc-java-5.3.0_multilib-x86_64-2alien
gcc-objc-5.3.0_multilib-x86_64-2alien
glibc-2.23_multilib-x86_64-1alien
glibc-i18n-2.23_multilib-x86_64-1alien
glibc-profile-2.23_multilib-x86_64-1alien
glibc-solibs-2.23_multilib-x86_64-1alien
install-multilib-1.1.0-x86_64-1dj

I switched back to original packages

Code:

glibc-2.23-x86_64-1       glibc-profile-2.23-x86_64-1
glibc-i18n-2.23-x86_64-1  glibc-solibs-2.23-x86_64-1
1) gcc-5.3.0-x86_64-2
2) gcc-g++-5.3.0-x86_64-2

and the problem persists

Code:

gcc a.c
a.c:1:1: warning: return type defaults to 'int' [-Wimplicit-int]
 main() {
 ^
/usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: /usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../lib64/crti.o: unrecognized relocation (0x2a) in section `.init'
/usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status

I dont get what could be wrong. The lib crti.o
is from glibc-2.23-x86_64-1 which is the 'sane' lib.

Anyone else with the same problem?

Found it.

binutils was binutils-2.25.1-x86_64-1.
I guess it was 2.23 before. Anyways I upgraded to
binutils-2.26-x86_64-1 and GCC is compiling now.

Today I had to compile something and I had this very problem.

Compiling this small sample program:

Code:

#include <stdio.h>
int main() {
fprintf(stdout, "Hello, world.\n");
return(0);
}

Got me this output:

Code:

[eduardo:~]$ gcc compiletest.c 
/usr/gnat/libexec/gcc/x86_64-pc-linux-gnu/4.9.3/ld: /usr/lib/../lib64/crti.o: unrecognized relocation (0x2a) in section `.init'
/usr/gnat/libexec/gcc/x86_64-pc-linux-gnu/4.9.3/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
[eduardo:~]$

I'm using gcc-5.3.0-x86_64-3 and binutils-2.26-x86_64-3. No multilib.

I ensured that both the gcc series and binutils were reinstalled before running this test.
Any help or hints?

Oh well. Please disregard. Was doing some Ada coding with GNAT (from AdaCore) on a custom location and forgot to set the proper env variables. My bad *facepalm*. All is well now.

Leaving it here because it might help someone find the cause of this annoyance.
