Linker, die nicht mit grundlegenden Bibliotheken in Cross Compiles verlinken

Ich habe einen Alpha -Cross -Compiler auf einem X86_64 -Host, der alles zu erstellen scheint, aber ich kann es nicht dazu bringen, dieses einfache Testprogramm zu kompilieren: < /p>

Code: Select all

#include       /* puts */
#include       /* atexit */

void fnExit1 (void)
{
puts ("Exit function 1.");
}

void fnExit2 (void)
{
puts ("Exit function 2.");
}

int main ()
{
atexit (fnExit1);
atexit (fnExit2);
puts ("Main function.");
return 0;
}
