Setting environment with a script

[A. Farber]

Hi,

I have a question not related to Perl's syntax, but to its usage.

I have a script which generates GNU Makefiles out of a bigger
number of input files. With that script I'd also like to
set environment variables for a build - so that I have one
big all-in-one script.

With Unix that's easy - I'll let the users call my script as

eval `create_makefiles.pl` in sh
and
eval `create_makefiles.pl -c` in csh

and generate export/setenv commands when called this way.

But what could I do to make it also work on Windows?
(in a DOS-window, not in Cygwin) Does anybody solve this
problem already or knows a module doing similar things?

Thanks
Alex

You've almost partitioned the problem but you've just stopped one step
short. You problem is about the ways processes can interact under
windows - the fact that one or more of the script is in Perl is not
relevant.

With Unix that's easy - I'll let the users call my script as

eval `create_makefiles.pl` in sh
and
eval `create_makefiles.pl -c` in csh

and generate export/setenv commands when called this way.

But what could I do to make it also work on Windows?

You can have the Perl script create a batch file the call that batch
file. There may be better ways but this is really a question about
Windows not Perl so perhaps you should ask in a Windows newsgroup.
