Ray,
Thanks for the pointers. I installed the libraries you mentioned, I had
managed to get the headers happening myself, but then managed to get a
link error. Further investigation, and a sudden memory flash reminded me
that clang still uses the system linker, which, you guessed it, is the
gcc linker. If I remember correctly, clang will default to using lld,
the new llvm linker with the release of V4 in a few days - but I need it
tomorrow. I therefore had to install gcc after all that....
With respect to using clang, the reason I use it is that it's stable,
but more importantly the error reporting is vastly superior to gcc which
helps with teaching. It tells the students where the actual error is,
not like gcc which wildly flails around and then points to something 8
lines away, confusing the bejezzus out of the students. I must also say
that contrary to what you've said and Oscar, who's email came in as I'm
writing this, clang, to me is very stable. I usually run Gentoo Linux
machines and there are very few packages that I can't build with clang.
Anyway, lets save the compiler battles for another day, it's 1:30
Monday morning and I can finally build my environment - yeah!!!
Thanks for the help everyone,
Andrew
