Title: GCC fails to compile anything
Post by: eagleking95 on February 19, 2016, 08:05:13 AM

Hello everyone. I have a TCL virtual machine on VirtualBox. I have installed gcc.tcz, gcc_libs.tcz, gcc_libs-dev.tcz and gcc_base-dev.tcz using Apps. However I cannot compile.

For example for the following C code:

Code: [Select]

int main() { return 0; }

Raises errors from /usr/local/bin/ld: cannot find crt1.o. If I add

Code: [Select]

#include <stdio.h> then it says: fatal error: stdio.h: No such file or directory.

Any ideas how can I get it to work? Thanks!!

It works, thanks!

However I came across another issue. I am trying to compile a program that is using ptrace to block some system calls but I cannot access their codes neither using __NR_<callName> or SYS_<call_name>. For example the compiler gives the error that __NR_socket or SYS_socket is undeclared.

I have included sys/syscall.h, syscall.h and bits/syscall.h ... I don't understand why it says it's undeclared. These constants are defined in those header files.

Any tips/ideas?

Hi eagleking95

For example the compiler gives the error that __NR_socket or SYS_socket is undeclared.

That's because they are called  __NR_socketcall  or  SYS_socketcall.

From  bits/syscall.h:

"Never use <bits/syscall.h> directly; include <sys/syscall.h> instead."

Information about what you are trying to compile and exact error messages will make it easier to help you.
