[fpc-pascal] linklib c using mingw, cygwin, both, or ...

[wolfram.klaeger at web.de]

I'm trying to follow the tutorial, How to use C code in FreePascal projects,

ftp://ftp.freepascal.org/pub/fpc/docs-pdf/CinFreePascal.pdf

In order to get gcc running on Windows, I tried both options, mingw and cygwin. This or that way, compiling hello.c to hello.o works. Linking hello.o to hello.pas via {$linklib c} fails, when hello.o was created via mingw/gcc. FPC can't find libc.dll or libc.a, since mingw does not install it. 

With cygwin's gcc, libc.a can be found straightforward, where I would expect it, in c:/cygwin/lib/. fpc compiles without warning, now windows needs cygwin1.dll. Done, as well, but my hello.exe still ends up with runtime error 216.

Any advice, another way around?

Thanks in advance
