I'm new to ML development, but from what I understand, ML uses its own custom stdio.c.

I'm also trying to use an official pre-packaged embedded-Debian arm toolchain, but the most recent version is for gcc-4.4.

So, I'm getting a lot of errors like this:

error: NULL undeclared (first use in this function)

Can the stdio-related macros be updated so that they will compile with an older version of gcc?

I've already compiled ML2.3 successfully using the arm toolchain for gcc-4.6.2, but as I mentioned, the most recent version of gcc for embedded Debian is gcc-4.4.

I think if Debian/Ubuntu people were able to easily install a pre-packaged Debian version of the arm toolchain, it might help spur development from that side of the aisle.

I'm trying to get things to compile on a Debian system for the first time, but I have a few issues. I don't want to brick my camera, so I am asking out of an abundance of caution:

1. Are there any Debian/Ubuntu repositories for the arm toolchain that people are using with success? I think it would be helpful to include platform-specific instructions in the README files.

2. The toolchain/summon-arm script is looking for patch-gcc-4.6.2-config-arm-t-arm-elf.diff in the wrong place.

3. doc/menuindex.py is complaining about "Could not open menuindex.txt". What should I do about this? Is this safe to ignore, or is it a fatal error?

4. doc/menuindex.py is complaining about "mkdir: cannot create directory `cam': File exists". What should I do about this? Is this safe to ignore, or is it a fatal error?

5. ld is complaining about "stat: cannot stat `autoexec.bin': No such file or directory", but then I objcopy creates an autoexec.bin file. What should I do about this? Is this safe to ignore, or is it a fatal error?

Thanks
