[Mingw-users] Noob question re: apr-util on Msys

[Bill B. <bb...@ne...>]

This is probably a basic issue, but I wanted to toss it out there to 
see if something obvious is at play (probably).

I have installed the 201204026 Mingw/Msys package.  The two are in 
different directories in the C:\ filesystem; \Mingww  and  \Msys.  The 
purpose of the install is specifically (so far) to build gstreamer 
with all its plug packages and specific options.

So I'm following the gstreamer wiki for building up Msys and Mingw to 
be able to  build gstreamer:
  ( 
http://gstreamer.freedesktop.org/wiki/SettingUpMinGWMSysEnvironment)

Install msys-libxml2 2.8.0
    Updating msys-libxml2 to 2.8.0 fixes a zlib-related crash some 
users reported. After mingw-get msys-libxml2 package is updated to 
2.8.0 or later, this step can be skipped.

Install msys-sqlite 3-3.7.5-2
Install msys-apr apr-1.4.5-1
Install msys-apr-util 1.3.12-3 & 1.5.1
Install msys-neon
Install msys-pcre
Install msys-swig
Install msys-subversion
Install msys-gperf
Install msys-getopt

Then there is another section for configuring and building up packages 
for mingw which I haven't even started yet.  I'm stuck on 
msys-apr-util.  I started off with the recommended apr-util-1.3.12-3 
which fails in numerous places (during configure and make), and also 
tried the latest from Adobe, apr-util-1.5.1.  It needed to know where 
the installed apr was (/bin).  After a buildconf and configure which 
seemed to go ok, doing a make, resulted in:

The original version of apr-util tried had similar types of errors 
which seemed to center around this section, as it was repeated several 
times:

/usr/include/cygwin/if.h:78: error: parse error before "caddr_t"
/usr/include/cygwin/if.h:80: error: parse error before '}' token
/usr/include/cygwin/if.h:82: error: parse error before '}' token

Can anyone suggest a possible solution to getting this compiled?

There seems to be a glut of inaccurate procedures for building up 
Mingw/Msys for a variety of compilation chores, and each of them seem 
somewhat sound (to me) but end up not working correctly for one reason 
or another, or not accurately defining which build should be in Mingw 
and which should be Msys.  You're just supposed to know, I guess -- 
which I don't.  This is probably my fourth Mingw/Msys build from 
scratch, but the first that I adhered just to the Gstreamer 
guidelines.

Thanks.
