[vorbis] Problem compiling ogg on OpenBSD-2.7

[Rakhesh Sasidharan]

> What do the last several lines of your libogg-1.0beta4/config.log say?
The last few lines seem OK.  I'm not attaching them, as I have got over
that problem. 

> What type of architecture are you running OpenBSD?
i386.

> CXX=gcc 
> export cc 
> export CXX 
> ./configure 
This solves the problem.  The whole thing compiles, and it installs the
libraries, include files etc.  Thanks a lot! Is it possible to get an
explanation of why things worked now (or what the problem was, earlier)?

But now I have other problem(s):

When compiling "libvorbis-1.0beta4", I get the following:

checking for Ogg... no
*** Could not run Ogg test program, checking why...
*** The test program failed to compile or link. See the file config.log for the
*** exact error that occured. This usually means Ogg was incorrectly installed
*** or that you have moved Ogg since it was installed. In the latter case, you
*** may want to edit the ogg-config script: 
configure: error: must have Ogg installed!

I checked config.log, and it reports the following:
--------------

configure:1759: checking for cos in -lm

Sorry, that was kind of big.  I didn't know what to do, but I was
surprised about ogg.h being missing.  I checked around, and it is
installed at /usr/local/include/ogg/ogg.h.

[root at OpenBSD](libvorbis-1.0beta4)# ls /usr/local/include/ogg/
config_types.h  ogg.h           os_types.h

Also, what exactly is the order in which I should compile and install
all the packages that I got from the ftp site ? So far I have installed
libogg; I tried installing libao and got the following at the "make"
stage:

[root at OpenBSD](libao-0.6.0)# make
Making all in src
Making all in plugins
Making all in oss
Making all in esd
Making all in alsa
Making all in arts
/bin/sh ../libtool --mode=compile gcc -DPACKAGE=\"libao\" -DVERSION=\"0.6.0\" -DSIZEOF_SHORT=2 -DSIZEOF_INT=4 -DSIZEOF_LONG=4  -I. -I. -I.. -I../include    -O20 -D__NO_MATH_INLINES -fsigned-char -DAO_PLUGIN_PATH=\"/usr/local/lib/ao\" -c audio_out.c

*** Error code 1

Stop in /intel/ogg/libao-0.6.0/src.
*** Error code 1

Stop in /intel/ogg/libao-0.6.0/src (line 228 of Makefile).
*** Error code 1

Stop in /intel/ogg/libao-0.6.0 (line 174 of Makefile).
[root at OpenBSD](libao-0.6.0)# exit

It was after this that I had tried libvorbis, and ended up with the
errors I had shown above.

Regards.
