Re: [simspark-devel] CMake and Autotools support

[Sander v. D. <sgv...@gm...>]

Hey,

I will try setting the minimum version to 2.4 and see what happens. If it
won't work it shouldn't be too big a problem to install a newer version (or
compile it, as on these systems we don't have root access). If it's too much
work to make it work under 2.4 I agree it's not worth it, was just wondering
if it would be a small fix to have it working out of the box with older
versions as in Ubuntu 8.04.

Thanks!

Sander
