RE: [Jython-users] Running a python script from java - help!

[Phil S. <psu...@es...>]

From the jnios  readme:

"This is a early release of the software, so don't be surprised if you 
find an error. jnios.cpp have at one time been compile on linux and 
solaris, but it have only tested in Windows. "

Others who posted to this list recently have confirmed that it does 
not at present work on linux. 

I hope you can get it working, it's a great package.

Subject: [Jython-users] Running a python script from java - help!




This is probably a really soppy question but I'm very very very stuck... 


I'm trying to run a python script from a java GUI.  I have had to use
jnios-1.7 to fix a problem I had with os.py, but now I'm getting:
java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: no posix in
java.library.path 


I tried to compile jnios-1.7/*.cpp, but it is looking for io.h, does io.h
even exist on UNIX?? 
config.h:35: io.h: No such file or directory 
Is there a precompiled unix version of posix.so that I can download?? 



I'm going round in circles here, ANY tips welcome!!!

Chars!
Shari
