Thread: problems with a C program on different machines, using different compilers

Hi

I have Fedora Core 5 2.6.17-1.2174_FC5 with gcc version: gcc (GCC) 4.1.1 200
60525 (Red Hat 4.1.1-1)

everything compiles well, and run smoothly on my machine. But the actual pro
duction machine is Linux 2.4.20-46.9.legacysmp
with gcc version gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5)

on the production machine, I get errors like:
1) warning #266: function declared implicitly
while ((read = getline (&line, &len, sfile)) != -1) {

2) undefined reference to `sem_init'
3) undefined reference to `sem_destroy'

while I am using the correct headers:
#define _GNU_SOURCE
#include <stdio.h>

for the getline

and
#include <semaphore.h>

for the sem_init and sem_destroy

I receive the same "warning #266: function declared implicitly" for my own d
efined functions as well, while my header is included,

any ideas where could be the problem,

sorry for asking a question that might be basic, but it is my first time to
move code between different machines in linux and compilers versions,

I appreciate any help,

thanks,

Manal

Hi

Thank you for your reply,

I am trying to talk to the administrators to do this, but didn't get a reply yet, and I have deadlines to catch, and afraid they might say they can't because of other users might find it conflicting with their work,

so, trying to plan for the worst actually, if there is any way I can fix my code to the older versions, I would like to learn it,

thanks again,
Manal
