Can't Compile on Linux

[MattS]

after unzipping source.zip and going into the directory i ran make and i get these errors:

Yeah.... any help would be nice :S

It looks like your math headers are wrong/missing somehow. I've not tested compiling Irrlicht with GCC 3.4.x so I'm not sure whether it will work or not, but look around for maths headers on your system and include them manually:

Code: Select all

fgrep -R 'GRAD_PI' /usr/include/*

That'll return any headers that have that define in, chances are, they will be linked to or include to define for sqrt, etc too.

Manually include this file into the irrlicht files that need it I guess.

As always, if using a distro, check that you have all the standard development packages installed, check and optional '-devel' packages to sdee whether they look like they will install maths related headers.
