Hi
For vaguely justifiable reasons I'm trying to get Csound running on the 
64bit version of Windows XP.
Some of the 64 bit binaries in the releases up to 6.08 work, most fail 
initially with a procedure entry point error regarding inet_pton which 
appeared in Vista (given the dialog box title seems to be to do with 
fluidsynth). After 6.08, none of the binaries work.

I have a VS2019 environment on Win10 with the v141_xp platform toolset, 
and had to do some slight alterations (namely bits with 
InterlockedExchange8/InterlockedExchangeAdd8 and InitOnceExecuteOnce, 
which aren't available in XP), and things were looking quite promising, 
but now I'm a bit stuck with threads.
There are quite a few things in threads.c that aren't available on XP, 
eg InitializeConditionVariable. I have started to try and use the 
pthread package from vcpkg in place of native Windows threads but may be 
getting myself into more problems down the line.
Before I do I thought I would see if anyone has any advice. I realise XP 
is well out of support so might be a bit of a dead end. I have not tried 
building with MSYS yet so perhaps there could be more joy with that 
route.

thanks
Richard

I have a working build now, although not completely tested, the 
contentious bits seem to be addressed so looks good. The actual code 
needed only few minor tweaks in the end, and most of the pain was around 
the tooling and alternative threading library (pthreads4w, non-MinGW 
pthreads).
This should work on newer versions of windows except for the reliance on 
an environment variable (LOCALAPPDIR, in XP it's APPDIR, causes a 
segfault). I considered making everything conditional and then 
submitting a PR, but given the probable low demand combined with 
awkwardness of tooling, it's probably not that worth it.

If anyone is interested the binaries are here, and if the topic comes up 
anywhere please do point in my direction and I may be able to help.

Thank you!
There are some limitations namely the Fluid opcodes and virtual keyboard don't work at the moment.
These are described on the page below which I have just updated with a 32-bit build for XP too, and will keep updated with any future builds.

Hi!

 

I think this is marvellous! I am sure there is still enough XP-s around, would be great to have a newer Csound available for them.
