How to resolve linker error "cannot find -lgcc_s"

I have 3 tiny files which I use to make a static library and an app:

test.h

#ifndef TEST_H
#define TEST_H

class Test
{
    public:
        Test();
};

extern Test* gpTest;

#endif

test.cpp

#include "test.h"

Test::Test()
{
    gpTest = this;
}   

Test test;

main.cpp

#include "test.h"
#include <iostream>

using namespac开发者_开发百科e std;

Test* gpTest = NULL;

int main()
{
    return 0;
}

BUILD

g++ -c test.cpp -o test.o
ar cr test.a test.o
g++ -c main.cpp -o main.o
g++ main.o -o app -Wl,--whole-archive -L/home/dumindara/intest/test.a -Wl,-no--whole-archive

ERROR (linking step)

/usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

I tried everything: using -static-libgcc and linking to static libstdc++. Can't get this to work. It is all due to --whole-archive flag. But I can't do without it.

You have a typo. -no--whole-archive should be --no-whole-archive. Fixing the typo fixes the linker error.

I think -- is the problem here:

-Wl,-no--whole-archive

Try with

-Wl,-no-whole-archive

edit

About not seeing the test symbol in your app with nm app: I think you don't need -L since you give full path and name of test.a - do either

-Wl,--whole-archive -L/home/dumindara/intest/ -ltest -Wl,-no-whole-archive

or

-Wl,--whole-archive /home/dumindara/intest/test.a -Wl,-no-whole-archive

With regards to the comments so far: just drop the -Wl option entirely. Let g++ do its thing.

As for not finding the symbol test with nm, why would you expect anything else? You don't use it, your program doesn't need it, so it isn't pulled in. (If for some reason you need to include an object file which isn't referenced, e.g. because static initializers will make it visible, then specify the object file---don't put it in a library, which is the standard way of saying don't include it unless needed.)

whole-archive works, you are just not linking the lib. The correct thing to do is :

ar cr libtest.a test.o

and link with

-Wl,--whole-archive -L/home/dumindara/intest/ -ltest

Just a note: whole-archive only works with static libraries (.a) not with shared libraries (.so) is my experience.
