[gst-devel] Re: Native Win32 build of GStreamer 0.8.1

Fri May 7 07:30:03 CEST 2004

Hello,

After the problems described in the previous mail, I continued with trying
to build libxml2-2.6.9.
The ./configure succeeded but the subsequent make failed because the only
make I have on my system right now is nmake.
I tried nmake but that didn't work too well either. (expects $(SHELL) iso
${SHELL} [curly braces] for example)

Then I tried installing msys. Running the configure for glib and pkg-config
resulted in the same problems as listed below with one (major?) difference.
The configure in msys reports 
	checking for Win32... yes
while the configure under cygwin reports "no".
How should I tell cygwin that I have win32?

Then I tried the configure of libxml2 under msys followed by a make but this
make resulted in errors like
- ./libtool: cygpath: command not found [*** should I worry about this
one??]
- an error in xpath.c within a win32 #ifdef (line 10927) where a closing ')'
was missing
  which I could fix myself
- next a lot of errors occured in nanohttp.c because of undefined WSADATA
Here I gave up a 2nd time today :-(

Any opinions on whether msys/mingw or cygwin is the best approach for me?
Do I also need to install MinGW? 
Should I use gcc iso MSVC cl.exe? or should the latter also work fine?

I understand that these beginners questions are not that relevant for this
list but I do appreciate any help,

Marc
