After editing the Makefile to give names (as mentioned in the readme) it compiled everything but then died on the final link.
It was trying to write the output to /src/ide I believe. (no such directory on my system).
I changed it to bin/TheIde and let er rip.
It then came back with
/usr/lib/gcc/i686-pc-linux-gnu/3.4.5/../../../../i686-pc-linux-gnu/bin/ld: ./bin/ide/GCC32-Gcc-Gui-Linux-Main-Shared/SelectPkg.o(.gnu.linkonce.r._ZTV14CallbackAction+0x8): unresolvable relocation against symbol `__cxa_pure_virtual@@CXXABI_1.3'
/usr/lib/gcc/i686-pc-linux-gnu/3.4.5/../../../../i686-pc-linux-gnu/bin/ld: final link failed: Nonrepresentable section on output
collect2: ld returned 1 exit status
distcc[23448] ERROR: compile (null) on localhost failed
make: *** [bin/Theide] Error 1
I'm not sure what to do with that.
I'm compiling using Linux
gcc -v

Please, try to remove
-ffunction-sections
from the
CC = c++ -c -O2 -Os -ffunction-sections
line.
Mirek
P.S.: I am sorry for linux troubles - we are seeking for capable Linux maintainer/releaser for years now...

I've not seen -ffunction-sections before. What does it do?
As far as Linux I might be able to give you a hand. Let me get more familiar with your system first though. After I get this up and running I'm going to try to make a autoconf make system for it. (If nothing else it will refresh my skills).

Well, -ffunction-sections is a flag for compiler that puts each function into separate section. This makes dead-code removal possible for the linker.
However, it unfortunately turns out that "ld" does not do removal anyway, and some ld versions react with the error message you have encountered (meanwhile, our own MinGW ld replacement "uld" is able to use this).
I have already encountered the error in ubuntu a "-ffunction-sections" is now removed from TheIDE GCC builder in Linux, but it looks like it somehow survived in makefile generator...
When thinking about autoconf etc, please keep always keep in mind the "synthetic" nature of Makefile. OTOH, if something is needed to be added to Makefile generator, we will be happy to do so.
Also, the whole linux distribution structure is open to discussion. What we have now is what we were able to put together with our limited resources...

Try using TheIDE for one or two weeks for professional development.
And after it switch back to your conventional environment with make.
You will find that conventional model unusably slow.
Using U++'s build environment is viery addictive 
I started using upp about 2 monts ago, but I can not imagine going back to make or scons world.

I wouldn't say that better!

Well, BLITZ is very different system. Please read the explanation again:) OTOH, BLITZ needs to know more about what he compiles than makefiles are able to provide (it is C++ specific, goes through files, checks things and even generates some stub C++ code).
For full debug mode rebuild, BLITZ can be as much as 4 times faster .
The reason why it seem slow at first is that because of BLITZ, we can avoid traditional system of compiled libraries - in U++, all libraries exist in source form only. If you compile any example for the first time, complete "U++ library" gets recompiled on the way (and gets cached).

Well I'll not argue the point since we both agree it is cool. However perhaps you can help with a bug. In Linux the sdlexample won't link the sdl library. How do I tell it to?

In Package organizer. (Project/Package organizer).
BTW, we have not tested SDL in linux yet (In fact, SDL is not a part of U++, we have added it to Win32 version just to make things easy for people interested in game development and not necessarily interested in U++ library). I would welcome fix there - the simplest would be to post here fixed .upp and .cpp files of SDLExample package.
