You are mixing the Cygwin and MinGW environments. This *will not work*. The thing you are trying to compile does not appear to have been ported to allow it to run on native Windows, and to run it on Cygwin would require a Cygwin-compiled gtk+, which is a whole new can of worms.

You have 2 options, as far as I can see - give up, or devote lots of time to either porting GPA, or compiling a Cygwin gtk+ (and all its many dependencies.)

Okay, I'll try another way.

Thanks alot for your help

Well, the undefined references to pipe and kill were "solved" by linking
one of the "forbidden" libraries (-lcygwin, -lc, -lg...), so it seems there
are at least dummy implementations, or do I misinterpret this?

As it looks like now, my only alternatives are: Linking one of those
"forbidden" libraries and getting a "multiple definition of `atexit'",
or not linking them and getting that bunch of undefined references.

What can I do here? I've been sitting on this problem for a week now, and
I don't have any ideas what more to try.

Actually, pipe and kill might not be. Don't know. You'd have to look and
find out.

Good to know... Anyway, the other ones should be there, don't they?

'fork' isn't available under MinGW.

Okay. The full compiler call is attached in file log1, the error message in
log2. It's everything left from the whole output of 'make'; all other jobs have
already run fine.

In short the error messages say, I get 'undefined reference's to QUITE a lot of
functions, among them some essential gcc functions like __assert, __errno,
pipe, kill, fork etc.

Yours,

Ahh. You will need to use the same setting as your gtk+ was compiled with.
Based on what you say above, I think that you will need -mno-cygwin.

But, you will *not* solve anything by adding -lcygwin.

Post details of the errors with -mno-cygwin but without -lcygwin.

Max.

It seemed to be the only way to avoid the undefined references I had before.
I had tried some other ways, but they either didn't work at all or yielded
the same result. (Explicitly linking with -lc, for example, got me the same
error message; just "libcygwin.a" was replaced by "libc.a".)

Okay, but what else?

To be honest, as long as I end up with a runnable gpa.exe for Windows, I
dont' care... I gave it a try using Cygwin.

Then GTK+-2.0 refuses to link.

It is, at least the binaries.

If you add -mno-cygwin, then you are trying to compile GPA for MinGW, not
Cygwin.

Aaargh! First you tell gcc to not use cygwin, then you tell it to sort-of
use cygwin.
No wonder its confused!

Solution: Don't do that.

Do you actually intend to compile GPA for MinGW or Cygwin?
If Cygwin, drop the -mno-cygwin.
If MinGW, make sure the gcc-mingw package is installed.

Conflict between libcygwin.a and GCC core libraries

[Markus Gerwinski]

Hi folks,

I'm currently trying to compile GPA (s. http://www.gnupg.org/gpa.html) on
Cygwin. To get it up and running, first of all I had to insert "-mno-cygwin
-mms-bitfields" into the compiler options. After changing some more stuff in
the makefiles, compiling runs fine now, but linking still causes trouble.
First, I got a lot of `undefined references' to functions as basic as
`__assert'. To get rid of them, I included "-lcygwin" by hand into the linker
options. Now, the undefined references have disappeared, but instead I get
the following error message:

  libcygwin.a: multiple definition of `atexit'
  crt2.o:crt1.c: first defined here

Since libcygwin and crt2 are both essential parts of the development
environment itself, I don't see a possibility how to solve this conflict.
Can anyone help me?

Thanks alot in advance

  Markus
