Compiling on cygwin

Hi all,

I am trying to compile apr-1.4.5 on cygwin 5.1 [1] with thread support
(pthreads) so I'm doing a

    ./configure --enable-threads=pthread

But configure says that apr will be non threaded:

    checking for main in -ltruerand... no
    checking for library containing modf... none required

    Checking for Threads...
    APR will be non-threaded  <--- D'oh!
    checking for sigsuspend... yes

My question is: is it possible to build apr with thread support on
cygwin. If so, how?

If this is not possible, should I try with mingw?

Thanks in advance,
Antonio

Hi,

I finally got it compiling with threads with cygwin (I was missing a
buildconfig first) but then I had a problem with winsock.h that
I didn't know how to solve.

I think I'll try out with MS Visual Studio 2008 Express Edition. That
should be more "native", I assume.

Thanks,
Antonio

I don't know about APR capabilities when built with Cygwin.  Building
with MinGW uses APR's thread implementation for Windows, so yes
threads will be supported.

Whether to build APR with Cygwin or MinGW should follow the general
Cygwin/MinGW choice:

* Unix-y code in your application that requires emulation?  Cygwin
* No Unix-y code in your application?  MinGW

Note that you can't build APR as a shared library with 1.4.5, but that
will hopefully be resolved in the next release.  (That's already
supported in trunk.)
