I am one of the developers of the Csound 5 project.

I created a build system for this project that uses SConstruct and, on Windows, MSYS/MinGW to build the entire project. This build system was working fine for years until a few days ago.

I upgraded my Python installation to Python 2.4.2, and reinstalled MSYS and MinGW with all versions current as of this date.

Now the build system does not work on Windows. It fails in the configuration portion of the build. The config tests produce compiler commands like this, and fail:

gcc -Wall -g -gstabs -O2 -D_WIN32 -DWIN32 -DPIPES -DOS_IS_WIN32 -mthreads -DBETA -DUSE_DOUBLE -I. -IH -IC:\utah\usr\msys\1.0\local\include -IC:\utah\usr\mingw\include -IC:\utah\opt\Python24\include -IC:\utah\usr\mingw\include -IC:\utah\opt\lua50\include -IC:\utah\opt\Tcl\include -IC:\utah\opt\boost -IC:\utah\opt\jdk1.5.0\include -IC:\utah\opt\jdk1.5.0\include\win32 -IC:\utah\opt\pd-0.38-4-devel-2\src -I\usr\local\include -I\usr\include -c -o .sconf_temp\conftest_0.o .sconf_temp\conftest_0.c

The problem appears to be caused by SCons using '\' to separate components of a pathname, instead of '/' which is what works with gcc.

How can I instruct SCons to create pathnames with '/' instead of '\'?

Is there any way to get the MSys sh to translate pathnames with '\' to pathnames with '/'? All commands passed to tools must use Posix style pathnames.

I am getting desperate, thanks for any help you can provide.

Regards,
Mike Gogins

I discovered that using massign inside an instr resets midi continuous controllers.
Is this supposed to be so ?

It would be good to be able to massign without resetting controllers, imho.
An attached csd shows the behaviour, when instr 2 is called, gkctrl1 resets to zero (Csound version of 13th Dec 2005 on windowsXP, coundrc =-odac16 -iadc16 -b128 -B2048 -M0 -m0 -+rtaudio=pa --expression-opt -d -+raw_controller_mode=1)

great ! very useful.

I also noticed that the vst plugin opcodes (vstinit family) seems to be gone,
at least I can't use them, and they don't show when trying csound -z.
Haven't tried rc2 yet, but will soon. Looking forward to usinng the chn opcodes.
