[Wine] Problem with FlexLM licensing

[Paul Jackson]

I'm trying to run up ModelSim (a commercial simulator for hardware 
description languages), which is licensed on FlexLM, using the hard disk 
number. This program isn't listed in the apps database.

I have a valid license, and the Flex tools are correctly identifying, 
under Wine, that there's a licence and that it's valid. They find the 
appropriate env variable, identify the license, and then confirm that 
the license is good. ModelSim has its own license diagnostic utility, 
and this also manages to find the license, and confirm that it's valid.

However, when I run up ModelSim itself, it complains about an invalid 
license environment.

I've got no idea what's going on here; presumably ModelSim is using a 
different mechanism to communicate with Flex when it runs its license 
diagnostic, and when it runs the app for real. I've tried running it 
under strace, but I haven't managed to get any clues on how it 
communicates with Flex.

Any ideas? Are there any known problems with running flex-licensed apps?

Thanks.
