I'm trying to use gcc-3.4 on the latest Ubuntu. The package is from debian snapshots.

It probably assumes different default directory structure, so for example I was forced to give it -I /usr/include/i386-linux-gnu/, which gcc-4 assumed implicitly.

Currently it compiles everything I gave it just fine, but it can't link. Even the simplest executable results the error:

$ gcc-3.4 ~/tmp.cc -o ~/tmp
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

Apparently you need to add the library /lib/i386-linux-gnu/libgcc_s.so.1 and the compiler expect the soft link /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc_s.so pointing it to the correct place, however:

$ ls -l /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc_s.so
lrwxrwxrwx 1 root root 18 2011-05-03 04:55 /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc_s.so -> /lib/libgcc_s.so.1


$ ls /lib/libgcc_s.so.1
ls: /lib/libgcc_s.so.1: No such file or directory

Fix the symlink, and all will be well

$ sudo ln /lib/i386-linux-gnu/libgcc_s.so.1  /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc_s.so

Now it works correctly!

$ g++-3.4   ~/tmp.cc -o ~/tmp
  • This is useful when working with the davidva/gcc49 copr in Fedora. I was missing the libgcc_s.so in the right subdir /opt/gcc-4.9.3/lib64/gcc/x86_64-fedoraunited-linux-gnu/4.9.3. – bgStack15 Jan 21 '18 at 4:02

for me the command:

sudo ln /lib/i386-linux-gnu/libgcc_s.so.1  /usr/lib/gcc/i486-linux-gnu/3.4.6/libgcc_s.so

does not solve the issue.

This command, instead, does solve it:

sudo cp /lib/i386-linux-gnu/libgcc_s.so.1 /lib/libgcc_s.so.1
  • If it compiles, it should be good. Are you using latest Ubuntu? – Elazar Leibovich May 11 '11 at 6:26

I had a similar problem, but in my case trying to install gcc 4.2 (to compile in Matlab Simulink) in Ubuntu 11.04

In my case I wrote:

sudo ln  /lib/x86_64-linux-gnu/libgcc_s.so.1  /usr/lib/gcc/x86_64-linux-gnu/4.2.3/libgcc_s.so

And now gcc-4.2 is compiling.
