linker unable to find __assert_fail

I'm trying to build a library that makes use of boost, and while the library compiles OK, it's hitting a weird linker error that I don't understand. I built and installed Boost 1.54 (also tried 1.52), which went fine.

It claims to not be able to find __assert_fail, which I think is part of the standard library. I tried to build everything in 64-bit. I'm on Fedora 16, using gcc 4.6.3

Any ideas?

__assert_fail is normally a part of libc. Do you have it in your /lib/libc.so.6 and/or /lib64/libc.so.6? – n. 1.8e9-where's-my-share m.
Yes -- it's present in both. And the invocation of g++ does have -lc, so it should be finding it [adrian@tiger cmappertools]$ nm /lib/libc.so.6 | grep __assert_fail 4c7f2700 T __assert_fail 4c7f2550 t __assert_fail_base 4c7f2700 t __GI___assert_fail [adrian@tiger cmappertools]$ nm /lib64/libc.so.6 | grep __assert_fail 0000003e1002ef00 T __assert_fail 0000003e1002ed80 t __assert_fail_base 0000003e1002ef00 t __GI___assert_fail – Adrian Heilbut
Then perhaps your libtool uses a bad link line. Try linking manually, or add -v to the linker flags to maybe see what's wrong. – n. 1.8e9-where's-my-share m.
Correct me if I'm wrong, but don't I see -nostdlib in the fourth line above (immediately above the first error message)? – Ken White
Yes, however -lc and -lgcc_s are specified explicitly. And I did try getting rid of the -nostdlib flag and it didn't make any difference.. – Adrian Heilbut

several years later, on different Fedora (29), later version of boost, gcc, etc.etc. I ran into the same problem. Led more by intuition than understanding I got rid of gcc visibility pragmas (i.e. I commented out all the: #pragma GCC visibility push({whatever}) ... #pragma GCC visibility pop) and that did the trick - it compiled, linked and run successfully.

As Tarni mentioned,

hidden symbol `__assert_fail' isn't defined

is indeed caused by #pragma GCC visibility push(hidden)

However, if you absolutely need to hide some function that calls assert macro, you should include before hiding any symbols, e.g.


// Wrong place to hide
// #pragma GCC visibility push(hidden) 

#include <assert.h>

// Right place to hide
#pragma GCC visibility push(hidden) 

void fatal_debug(int foo, int bar){
    assert(foo == bar);
}


#pragma GCC visibility pop
