Whatever I try to compile in Cygwin I get the following output:
checking for mingw32 environment... no checking for EMX OS/2 environment... no checking how to run the C preprocessor... gcc -E checking for gcc... gcc checking whether the C compiler (gcc ) works... no configure: error: installation or configuration problem: C compiler cannot creat e executables.
The last few lines of the logfile look like this:
configure:2810: checking for EMX OS/2 environment
configure:2822: gcc -c conftest.c 1>&5
configure: In function `main':
configure:2818: error: `__EMX__' undeclared (first use in this function)

configure: failed program was:

return __EMX__;
; return 0; }

This is a fresh Cygwin install with G++ and a bunch of other devtools added. Any idea what I need to do to get this thing working?
Update 0: Nick, your link to http://www.geektimes.com/linux/troubleshooting/c-cant-create-executables.html was tried already - unfortunately this instructions are for redhat and do not seem to apply to cygwin.
Your Configure is wrong.
Usually autoreconf -f helps. If not you need to check the failing rule and fix it.
