构建文件时的Eclipse CDT错误

Question

When trying to build a simple Hello world program in C and Elcipse, I get the following errors:

make: *** [C.exe] Error 1 CC/C++ Problem

recipe for target 'C.exe' failed makefile /C/Debug line 29 C/C++ Problem

undefined reference to `WinMain' C line 39, external location: C:\\cygwin64\\usr\\src\\debug\\cygwin-1.7.33-1\\winsup\\cygwin\\lib\\libcmain.c C/C++ Problem

I'm using Cygwin. How can I fix this? I am selected the Cygwin toolchain, and I have the PATH set to C:\\cygwin64\\bin.

Answer 1

The undefined reference means you are missing a library. To set this up right click the project, select Properties -> C/C++ General -> Paths and Symbols -> Libraries and Libraries Paths . Add the appropriate library and build again.

Also look here - gcc-undefined-reference-to and here .
