undefined reference to `main' [message #506721]

I started a new workspace and created a simple Hello World C program. When I build the project I get

**** Build of configuration Debug for project Try1 ****

make all 
Building file: ../Main.c
Invoking: GCC C Compiler
gcc -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"Main.d" -MT"Main.d" -o"Main.o" "../Main.c"
Finished building: ../Main.c
 
Building target: Try1
Invoking: GCC C Linker
gcc  -o"Try1"  ./Main.o   
/usr/lib/gcc/i486-linux-gnu/4.4.1/../../../../lib/crt1.o: In function `_start':
/build/buildd/eglibc-2.10.1/csu/../sysdeps/i386/elf/start.S:115: undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [Try1] Error 1

in the console window.

I then build the canned Hello World C++ program in the same workspace. It builds and runs fine. I then try to rebuild my Hello World C program and it builds and runs fine.

This stuff is driving me nuts! Can anyone help?

Thanks.

Please show your code.

Do 'gcc main.c -o Try1' and tell us if it works.

I've tried so many things since my original post that I can no longer get back to the state that I was in then. I've since reinstalled Eclipse using files directly from the Eclipse website rather than installing the package that came with my Linux program and seem to now be up and running OK.

Thank you for your interest though.
