linking multiple function from .lib to CYGWIN

[Mümin A . via Cygwin]

Hi,

I can only link one function at a time in a *msvc *built library but when I
use multiple functions in the CYGWIN
compiler,  I got that error message.

int main()
{
helloWorld2();
return 0;
}

That is compiled and linked successfully.

int main()
{
helloWorld2();
helloWorld3();
return 0;
}

That is  compiled but linking throws  a bug report.
