- Subject: Problem of compiling and linking the C/C++ program using WIN32API with GCC
Hi,
I am a new CYGWIN user.
I actually tried to compile and link a C/C++ program using the 'w32api',
more exactly, the '/lib/w32api/libws2_32.a' library, with the following
command:
$gcc -o myprogram -lws2_32 -c myprogram.c
But, I always got the error messages from the 'ld' linker dynamic, such as:
- "Undefined reference to 'WSAcleanup@0'"
- "Undefined reference to 'WSAstartup@8'"
- "Undefined reference to '_inet_addr@4'"
- "Undefined reference to '_socket@12'"
- "Undefined reference to '_connect@12'"
- etc...
"collect2: ld returned 1 exit status"
This means that the linker dynamic 'ld' is unable to find and open the
corresponding 'libws2_32.a' library file.
I've also tried several other solutions, such as:
$ gcc -o myprogram -L /usr/lib -lws2_32 -c myprogram.c
or
$ gcc -o myprogram -l /usr/lib/w32api/libws2_32.a -c
myprogram.c
With these solutions, I've got the error message from 'ld' like this:
"Cannot find the -l/usr/lib/w32api/libws2_32.a"
"collect2: ld returned 1 exit status"
Someone can help me to resolve this problem
Thanks,
