mzscheme extension problems

[Stephane Letz <letz@grame.fr>]

Hi,

We have some problems in developing an extension that use threads.

First i compiled and load successfully the extension in Drscheme. Some
functions worked, but because the external code open OS threads, i've got
several segmentation fault.

Using the 103 distribution, I compiled the system with OS threads, but had
to hack the linux_thread.c file to make it compile (Linux kernel 2.4.3
Mandrake 8.0 distribution)

I tried to load again the extension but now get the error :  "undefined
symbol : scheme_current_process"

I tried also to link the mzdyn.o file into my .so extension but get the error :
"multiple definition : scheme-initialiez-internal"

I tried the CVS version but can not compile because of errors when
compiling the linux_thread.c file.

Any ideas?

Thanks

Stephane Letz
