So I thank you for your help...I have upgraded my compiler to 4.0.2 and now I have what
looks like linking issues. Any help is greatly appreciated.
Here is sample code:
[test]$ more test.cpp
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <stddef.h>
#include <ostream>
#include <iostream>
#include <fstream>
using namespace std;
int main(int argc, char *argv[])
{
char *filename;
fstream filein;
setbuf(stdout,NULL);
filename = argv[1];
filein.open(filename,fstream::in);
if (filein == NULL)
{
printf("Error opening %s\n",filename);
exit(2);
} else {
printf("File opened correctly %s\n",filename);
}
return 0;
}
-----------------------------------------------------
My makefile:
[test]$ more makefile
DEBUG = true
SHELL = /bin/bash
OBJECTS = test.o
#ifeq ($(DEBUG),true)
OPS = -w -g #-O3
#else
#OPS = -w -O3
#endif
test: $(OBJECTS)
gcc $(OPS)-o test $(OBJECTS)
test.o: test.cpp ; gcc $(OPS) -c test.cpp
clean: $(OBJECTS) test; rm -f $(OBJECTS) test
-----------------------------------------------------
