Title: Nspire Online Compiler
Post by: compu on May 02, 2011, 03:20:31 pm

I made a small tool that lets you upload a zip archive containing source code of an nspire program and compiles it.
You can modify the EXE and OBJS variables in the makefile to whatever you want.

It uses arm-elf-gcc 4.4.6 because I have problems to get 4.5 to work.
__builtin_unreachable() was added in 4.5 so you will always get a warning:

Code: [Select]

/home/julian/ndless/include/os.h: In function 'exit':
/home/julian/ndless/include/os.h:389: warning: implicit declaration of function '__builtin_unreachable'

Hmm nice, is this for ASM and C or Lua?

At the moment, only C is supported, but it is easy to add Asm.

What OS is the server running? (for arm-elf-gcc)

Debian with Linux Kernel 2.6.18.

Letting anyone run arbitrary commands on your server isn't a bit risky? Or are there any filter mechanisms?

PHP has a filter function called escapeshellcmd() that will filter all |, ;, etc. out.

Couldn't you still run arbitrary commands by changing nspire-gcc in the makefile to anything you want?

Probably, unless he uses REGEX to filter out non-GCC calls.

Yes, I have accidentally moved the directory, I will fix it as soon as possible ;)
