Subject: "multiply defined" error
Date: Sun, 14 Nov 1999 15:30:00 -0000 [thread overview]
Message-ID: <942622165.193303@marvin> (raw)
Hi,
I compiled all my .cc files (including a file with main() ) with g++ -c
This worked fine.
Now, I want to fit everything together with g++ file1.o file2.o file3.o ....
but this gives lots of errors, all the same.
The errors look like this :
-----------------------------------------------------------
ld: fatal: symbol `MCL::MCL(char *, char *, char *)' is multiply defined:
(file mcltrain.o and file mcl.o);
-----------------------------------------------------------
Why is this ?
I DID include lines likes this in my files :
-----------------------------------------------------------
#ifndef File1_h
#define File1_h 0
...
#endif
-----------------------------------------------------------
Please help me out.
Thank you!
Emmanuel Lambert
