Thanks Dan i will for sure check your package but right now i'm still
struggling with my build.Once more i tried to build it with libc
obtained from your minibasic port.After first build i still receive
bunch of errors and so after second time.Issuing a make for third time
gives no errors and i can see .hex file in project folder.Any idea
what's going on?
Regards.

Don't apologize. In the next release, I'll be sure to mention that

Hello again,
Nevermind the questions about makefiles It was a problem with the windoze
PATH environment variable It was because of the openocd entry in the PATH
E.V. (conflicts between cygwin and openocd sh.exe inside the C:\Program
Files\openocd-r423\utils\bin directory). Just removed the 2 entries of the
openocd in the PATH and everything compiled at the first time
Sorry for the previous posts about this ;)

Im almost getting to the point of compiling this in linux, but I have to

Can someone give advice here?

Ah, cool. I'll have to load up the Winders version of the tool chain
and try it out. The newlib I use is the one that the Gentoo
'crossdev' tool selects.
Thanks,

Dan, if you don't mind, I'd like to include your Makefile in my
next
release. I've made a handful of changes to the codebase for another
project, and have plans in the next couple weeks to backport them into

One more thing.... your demo requires the version of newlib without
the syscall stubs and without reentrant syscalls. WinARM and most
distributions don't have this. I compiled a newlib with this. It
should be in the distribution of
minibasic-arm-0.5e.zip
in the LPC2000 Group files section. There is a libc.a, libm.a, and
libg.a in there that should work with the LPC 2148 demo. I had to
include "-nostartfiles" in the linker line so it would use my stripped
down newlib rather than the full version. You can distribute this
library with your code if you wish (it's just a customized newlib).
