   The arm toolchain is 32 bits the gcc is 32 bits my ubuntu linux is 64 bits is that why it is getting invalid conversion from int?

   josheeg@josheeg-desktop:~/libmaple$ make install

   Perhaps.. If the compiler is producing 64-bit code then int may have 64-bit precision while timer_dev_num is 32-bit (but I would expect it to only give a warning if anything).

   Anyway, the compiler should be producing 32-bit ARM code, not x86_64/IA64 (whichever you're using) regardless of the host's architecture, so most likely your target architecture is set wrong.

   Are you sure you have included the correct header file which defines 'timer_dev_num' ?
   Have you changed the c compilers flags in the makefile?

   I found the definition of timer_dev_num, and it's an enum, and so I'd expect there to be no problems, BUT, you'd get that sort of error if the compiler was confused about the type. Another possibility (but I'd expect a slightly different error message) is if the enum is a short, and there were a strict check that the timer_dev_num is a short, and hence the int is losing precision (but that error used to be a different message)

   1. maple tutorials problem it doen't mention removing BRLTTY & the unzip
   command doen't work with the * wildcard tiping it out that part works.

   2. A solution I got from the leaflabs team "It's unlikely that this is a 64 vs. 32 bit Linux problem. The file test-session.cpp had a bug in it that later changes to libmaple uncovered. I pushed a fix to github the other day that should fix this problem.

   Try updating your git repo, then compiling again. From the libmaple directory, run:

   $ git pull origin master
   $ make clean
   $ cp examples/test-session.cpp main.cpp
   $ make"

   3. then last I am having trouble getting my path info right in ubuntu 10.10 I loaded this like in eatch time so the fixed path info should not be a problem.

   "then afterward I try the original compile again and get this error

   I also tried make again and get this error last time I had to fallow the install procedure again.

   josheeg@josheeg-desktop:~/libmaple$ make

   [...]
   /bin/sh: arm-none-eabi-gcc: not found
   make: *** [build/./libmaple/systick.o] Error 127

   This is a problem with your PATH environment variable. Make sure that you have correctly set your PATH to include the directory which contains arm-none-eabi-gcc."

   so can anyone assist me with the correct path script or string to make the gcc compiler or g++ one with the tutorial to work?
