Re: Compiling HOpenGL under recent versions of GHC

Hi ppl,

i thought i would add some comments, being a Gentoo user:

groovy, ta. I have my own shell scripts as well, to automate the build 
process from CVS, but this may make things even easier. The Gentoo 
ebuild system is excellent.

I recently built GHC CVS on my Gentoo linux and I did have problems 
which i think were with the hopengl if i recall correctly.

i also had problems with objectio, either in the snapshot or CVS or both,
but the build was fine when objectio was not enabled.

BUT, the ghc-6.3.20040504 CVS snapshot was OK. It compiles HopenGL 
apps fine, eg the glxgears app that was recently posted on this list. I havent
tried running any HopenGL apps with the ghci from that snapshot tho.

It is a shame the Redbook examples have not yet been modified also, to suit 
the new GHC package inclusion syntax tho :(

I will run those tests that Svenne suggested and post my results, both for 
the ghc-6.3.20040504 CVS snapshot and the latest CVS. But not tonight.

cheers,

John
