Currently the .so is in the same directory as the application, and the main
application is marked as x86.
running: MONO_LOG_LEVEL=debug ../MONO312/bin/mono SimuladorPDV.exe
I got:
Mono: DllImport error loading library
'/home/mueller/simulador/libnfcepack_agente.so':
'/home/mueller/simulador/libnfcepack_agente.so: wrong ELF class: ELFCLASS32'.
I'm also able to run others x86 applications on this mono installation, but
those app's doesn't [DllImport] and p/invoke other's .so
Can you confirm that mono is should work with this setup?

AFAIR your x64 mono will jit to 32 bits your x86 marked DLL if the main
application is also marked as x86 , and then it will p/invoke properly your 32
bit .so, although in Linux where to place .so files is a bit more complex.

Hi,
I forgot to say, but I'm trying to build it as x86 on a x64 machine - the
compilation as x64 worked (without the --host)
Compilation on a x86 box also worked.
This problem happens when I compile as x86 on a x64 box.
Thanks,
Rafael

Hello,
I am not sure why you are passing a --host command line option. Configure
should be able to figure this out on its own.

Hi there,
My (c#) application (compiled on windows, as x86) needs to load a 32 bits
library (.so), so I must compile mono as x86, right?
I've downloaded the 3.12 source and configured it with
./configure --host=i386-pc-linux-gnu
But it always fails to compile:
In file included from mono-context.c:8:0:
mono-context.c: In function ‘mono_sigctx_to_monoctx’:
../../mono/utils/mono-sigcontext.h:144:74: error: ‘REG_EAX’ undeclared (first
use in this function)
#define UCONTEXT_REG_EAX(ctx) (((ucontext_t*)(ctx))->uc_mcontext.gregs
[REG_EAX])
I've tried to add AC_GNU_SOURCE on configure.ac<http://configure.ac> and also
compiling with CFLAGS="$CFLAGS -D_GNU_SOURCE" but I still can't compile it.
I'm doing anything wrong? Any other advice to compile it on x86?
I've also tried with mono 3.2.3 and 3.6, without success.
Kind regards,
Rafael
