`cannot find "-lgcc_s"` from gcc-3.4 on Ubuntu 11.04

  • 772

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
ubuntu patch-management gcc g++

    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

    And

    $ 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

  2. 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.

  3. 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
