Description giona.imperatori 2016-12-13 10:33:40 UTC

I'm filing this bug as suggested by the compiler error message.

I'm trying to compile Mono for ARM.
I followed the instruction found here (which seems quite old, based on 1.xx): http://www.mono-project.com/docs/about-mono/supported-platforms/arm/

Building for the host AMD64 linux (Ubuntu) machine went smoothly.
In the ARM ScratchBox I got the following error during the ./configure step

checking pthread.h presence... yes
configure: WARNING: pthread.h: present but cannot be compiled
configure: WARNING: pthread.h:     check for missing prerequisite headers?
configure: WARNING: pthread.h: see the Autoconf documentation
configure: WARNING: pthread.h:     section "Present But Cannot Be Compiled"
configure: WARNING: pthread.h: proceeding with the compiler's result

Hey Vladimir,

Can you take a look at this one?
Comment 2 Vladimir Kargov 2016-12-15 21:49:32 UTC

Could you specify what version of Scratchbox were you using?
Comment 3 giona.imperatori 2016-12-16 08:13:45 UTC

I used the repo "http://scratchbox.org/debian hathor main", so I guess I got the latest version from there.
Since I was not able to proceed I purged everything from my machine, that's why I now not able to give you the exact version.

Can you still reproduce with latest version of Mono?
Comment 5 Ludovic Henry 2018-01-24 16:24:24 UTC
Please provide a reproduction case if you can still reproduce to reopen. Thank you.
