Hi,
I got a few errors like [quote]multiple definition of `main’[/quote] hen linking a simple program. Since I didn’t know what was happening I made the program a bit simpler and tried again.
The program is just a hello wolrld program. You can copy/paste the code:
#include <iostream>
using namespace std;
void hello();
main()
{
hello();
}
void hello()
{
cout << "hello world" << endl;
}
the thing is, to compile I used
gcc -c hello.cc
gcc -o merge merge.cc -I/usr/tools/root/pro/include merge.cc -L/usr/tools/root/pro/lib -lCore -lCint -lHist -lGraf -lGraf3d -lGpad -lTree -lRint -lPostscript -lMatrix -lPhysics -lpthread -lm -ldl -rdynamic -L/usr/lib/gcc-lib/i386-redhat-linux/3.2.2 -lstdc++ -lg2c
Note that it would link all right using just
gcc -o merge merge.cc -L/usr/lib/gcc-lib/i386-redhat-linux/3.2.2 -lstdc++ -lg2c
but I decided to try the same libraries I used in the first program.
I’m using gcc 3.2.2 in Red Had 9.0 and ROOT 3.05/07 (for reasons of compatibility I don’t know exactly about I haven’t been able to update)
I don’t know what could I be misssing. Any help is greatly appreciated
