I don't know the specifics for liblo.

The normal GNU build approach with third party libraries and MinGW for SCons is:

1. Download the sources.

2. Untar them in your home directory.

3. Change into the base source directory.

4. Run ./configure.

5. Run make.

5. Run make install (on Linux, that would be sudo make install). This SHOULD put the libraries into /usr/local/lib, the binaries into /usr/local/bin, and the headers into /usr/local/include. With MSys/Mingw/ the /usr directory may be inside MSys/1.0/local or something like that -- can't recall exactly. 

6. SCons SHOULD already know how to look in /usr/local/lib, /usr/local/include, etc. so after that you SHOULD be able to link.

7. But if not, put the COMPLETE PATH for '/usr/local/lib' into custom.py, same for bin and include. Might be c:/utah/usr/MSys/1.0/local/lib. Depends on how you installed things.

I think it might help if you examined the Web documentation for the Filesystem Hierarchy Standard at http://www.pathname.com/fhs/pub/fhs-2.3.html.  GNU, MinGW, MSys, etc., all try to follow this pretty closely. Keep in mind that there are (way too many) variations on the theme. But the basic idea is, build in your home directory or in /usr/local/source/liblo or whatever, then install into standard locations (which will usually be /usr/local/ib for libraries and /usr/local/include for headers), then the compiler should automatically know where to find them.

Hope this helps,
Mike

James,

I haven't tried this myself, so I might be wrong, but the configuration log
says that it's looking for liblo-0.22/lo/lo.h, not just lo.h.

You've supplied the path:
    customCPPPATH.append('c:/utah/usr/liblo-0.22/lo')
but you should probably provide:
    customCPPPATH.append('c:/utah/usr')

Worth trying at least.

Sigurd

re: winbuild of OSC opcodes, csound scons cannot find lo.h.  I'm stumped, 
again.  I tried also putting cvs liblo.a in windows32 folder to no avail.  
Still no joy with this build business.

bash script...
my.sh:
#!/bin/sh
c:/python23/python c:/python23/Scripts/scons  buildInterfaces=1 
buildPythonOpcodes=0 useOSC=1 buildLoris=0 buildStkOpcodes=0 gcc3opt=0 
noDebug=0 buildPDClass=0 useDouble=0 dynamicCsoundLibrary=1 $1 $2 $3 $4


MSYS:
>./my.sh

System platform is 'win32'.
Build platform is 'mingw'.
SCons tools on this platform:  ['default', 'mingw', 'gcc', 'g++', 'gnulink',

'ar', 'gas', 'm4', 'tar', 'zip']
