[Mono-dev] Cross-compiling Mono for ARM

Yes… We was looking at it and looks that they changed lots of standard headers…

Unfortunately, here in Brazil they don’t have a dev team, only in France and take ages to get a reply…

Will try get them on table and see what we can do…

Thank you,

Best regards,

From these:
...arm-elf/include/stdint.h:243: error: conflicting types for 'intptr_t'
...arm-elf/include/stdint.h:244: error: conflicting types for 'uintptr_t'

it is pretty clear that ingenico messed with the standard header files, and guard clauses (#IFDEFs) aren't thus able to avoid such duplications, You'll need to see how to avoid the duplication but that may instead define things wrongly for symbols mono uses.

I wish you luck,

O..:.)oooo

Hello Andres...

I think I finally got it compiled but, now when I'm including on my C project the mono headers, my app don't compile anymore:

Any clues?


Thanks

Hey, I recommend you to put more details on what you have already tried.
For example the details you already posted on the gitter channel when you were talking with Miguel about using CC='armv6-cc' ./configure.
