Getting Error: "In function `_start': Undefined reference to main"

[Roy Strachan]

When trying to compile a simple test program I get the error: "In function `_start': Undefined reference to main". Of course there is a 'main' in my program (but no '_start', which must be a control in c::b).  Does anyone know how to get past this?

This is a Compiler (Linker) Error; without knowing your compiler the only thing to think is wrong is user error (or bad compiler).

Your likely typo-ed the word main (case-sensitive) or the arguments it takes or the return type.

My problem when I got this message turned out to be a file name problem. I had named my main module 'main.cc'. I removed it from the project, renamed it to 'main.cxx', and added it back into the project. The error disappeared.
