Hi !

- The log extract was probably too short sorry, here is a longuest version.
- The 'java' command was already found by the shell (and JAVA_HOME is set),
no problem here.
- All the paths in the -L directives (and -I ones) are correct.
- If "jvm.dll" (under windows) file isn't correctly located, we get a normal
"cannot find -ljvm ..." error. I located mine by adding the *-L/F/PROG/Java/
**jdk1.6.0_23/jre/bin/client *directive. Note that if I use the "*
jdk1.6.0_23/jre/bin/server/jvm.dll" *instead of the "*
jdk1.6.0_23/jre/bin/client/jvm.dll*' one, we get the following error :
"*f:/PROG/Java/jdk1.6.0_23/jre/bin/server/jvm.dll:
file not recognized: File format not recognized*"
- The remaining error always seems to be linked with that jvm.dll file but
how (...?)

Longuer extract :
