Trying to give more information.

that is what mingw is all about."
My problem about this was: Of the library I need I just had the headers,
some .cpp and a configure script, which created the makefiles (The name of
the library is GiNaC, a lib for symbolic computation, see www.ginac.de
for more information and if this is of any interest). As I somewhere read
that "porting ``Unix-type'' code is not necessarily trivial." I decided to
stick to cygwin 'cause it provided the POSIX functionality. I hoped the
-mno-cygwin flag would allow to build cygwin.dll independent executables
(The institute I work for just uses WinNT...). Unfortunately I didn't read
or understand the HowTo I wrote of in my last mail (
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/mno-cygwin-howto.txt
).
The author describes that one needs the mingw headers and libs to use the
-mno-cygwin and, well, it seems, I don't have these because I built the
library with the cygwin gcc. Unfortunately no workaround was given in the
HowTo so does anyone else have an idea how to make it work anyway.
eg would it be worth trying to build the whole library with the flag, or
should I better switch to Mingw32 (If yes has anybody information about
porting from POSIX to winpaths etc) or UWIN.
Hoping this gave more of the information you needed
