Mono 2.4 for ARM

I’m trying to build Mono 2.4 for an ARM device, following the instructions at http://mono-project.com/Mono:ARM and using an existing Scratchbox configuration.

I downloaded mono-2.4.tar.bz2 and extracted it with `tar xjf`. The host-mono part went fine, but when I tried to do the Scratchbox part, I had no “arm-mono” directory. When I tried to

> ./configure --disable-mcs-build

> make 

> make install DESTDIR=`pwd`/tmptree

in the mono-2.4 directory, `make` gave me a lot of warnings, and finally a series of “undefined reference to `GC_local_malloc'” errors, culminating in

collect2: ld returned 1 exit status

make[3]: *** [pedump] Error 1

make[3]: Leaving directory `/home/jon/src/dev/alp/cross/mono-2.4/mono/metadata'

make[2]: *** [all-recursive] Error 1

make[2]: Leaving directory `/home/jon/src/dev/alp/cross/mono-2.4/mono'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory `/home/jon/src/dev/alp/cross/mono-2.4'

make: *** [all] Error 2

Are there more up-to-date build instructions somewhere? Is ARM only supported for 1.x? Or am I just too stupid to get Mono running on our platform?

Many thanks. --with-tls=pthread got me past my first hurdle.

Alas, now I get

mini-arm.h:28:2: error: #error "At least one of ARM_FPU_NONE or ARM_FPU_FPA or ARM_FPU_VFP must be defined."

and I can’t seem to get past that. I’ve tried

./configure --disable-mcs-build --with-tls=pthread ARM_FPU_NONE=1

and

make ARM_FPU_NONE=1

and

ARM_FPU_NONE=1 make

and

export ARM_FPU_NONE=1

make

and I keep getting the same error. What do I have to do to enable software floating point (gnueabi)?

Hi,

  Try mono 2.4.2, or pass --with-tls=pthread to configure.

I tried

make –D ARM_FPU_NONE

but not

make –DARM_FPU_NONE

however, on Ubuntu 8.04, both give me

make: invalid option -- D

Use:

make -DARM_FPU_NONE

Excellent – thanks!

Now I get as far as

MCS     [net_2_0] convert.exe

make[2]: *** [convert.exe] Error 1

And I suspect that that is going to have to be between me and our Scratchbox maintainer: I have gmcs outside of Scratchbox but not inside it.

(I also suspect that I’ve been a bit spoiled by (once upon a time) Delphi and Visual Studio, and (now) by having a build engineer who maintains our Jamrules – this ./configure && make stuff is not anything I’m used to.)

Hi,

Use:
./configure <...>  CFLAGS=-DARM_FPU_NONE
