I'm following the instructions to cross compile for win32, and when I reach the configure step, I get errors telling me that I lack libraries (libmad) or header files (for libfaad). However, when I look for these files, they appear to be in ordinary places, such as /usr/local/lib and /usr/include. Can anyone tell me what I must change?

Here's the error message I get when running configure:

Code: Select all

$  ../extras/package/win32/configure.sh --host=i686-w64-mingw32
<lots of checks...>
configure: error: Could not find libmad on your system: you may get it from http://www.underbit.com/products/mad/. Alternatively you can use --disable-mad to disable the mad plugin.

...Yet when I look for libmad using `find` or `aptitude`, it appears to be installed. (Indeed, I downloaded the library from the url given in the error message):

Code: Select all

$ find / -name libmad.so
/usr/lib/i386-linux-gnu/libmad.so
/usr/local/lib/libmad.so
/home/<me>/Downloads/libmad-0.15.0b/.libs/libmad.so

$ aptitude search libmad

i A libmadlib                       - mesh adaptation library                   
p   libmadlib-dbg                   - mesh adaptation library                   
i   libmadlib-dev                   - mesh adaptation library

I also tried including the `--disable-mad` flag in my call to the configure script, but that yielded the error:

Code: Select all

configure: error: Cannot find development headers for libfaad...

...Yet the libfaad headers too appear to me be in their proper place:

Code: Select all

$ find / -name faad.h
/usr/include/faad.h
/home/<me>/dev/win/vlc/contrib/i686-linux-gnu/include/faad.h
/home/<me>/dev/win/vlc/contrib/win32/faad2/include/faad.h

Oh course, the one in /usr/local/lib/ are not for Win32!
Look in your config.log at the place where it searches for 3rd party.

Ah. Then do I need to add dirs to my PATH variable to include subdirs within <vlc root>/contrib/win32?

My config log provides the following details (among others):

Code: Select all

hostname = markham-Latitude-D830
uname -m = i686
uname -r = 3.5.0-17-generic
uname -s = Linux
uname -v = #28-Ubuntu SMP Tue Oct 9 19:32:08 UTC 2012

/usr/bin/uname -p = unknown
/bin/uname -X     = unknown

/usr/convex/getsysinfo = unknown

No, you might need to symlink your win32 to mingw32
