IntelC++ Compiler V8.0 - Link error

[vimalvinayan]

> icc -o -fast *.cpp
NLMG.h
NRUTIL.cpp -> NRUTIL.o
NLMG.cpp -> NLMG.o
NRUTIL.h

The compiler creates the *.o files without any problems.

>icc -o roll_icc NRUTIL.o NLMG.o -lm

Getting this error when I try to link all the *.o files

/usr/lib/crt1.o(.text+0x18): In function `_start':
../sysdeps/i386/elf/start.S:77: undefined reference to `main'

Platform : SUSE Linux (Opteron)

Thanks

Make sure you've run the script "iccvars.sh" to set up the necessary build environment before using the "icc".

I don't remember exactly when the change was made, but icpc is the command currently intended for linking C++.

If you run nm on the .o file you make when compiling the main() function (with -c, but without the -fast option), the main symbol should show there. Your link message says no main() function is found.

Thanks Jennifer and Tim

I was able to download Version 9.0 of the Intel C++ compiler. Didn't have any problems with it.
