[Mono-list] Mono on Xeon Phi

[Yury Serdyuk]

Hi !

I have tried to do the first steps to cross-compile Mono for Intel Xeon 
Phi coprocessor.

At first, I've tried to configure Mono as

 >./configure --prefix=<..> --host=x86_64-k1om-linux CC="icc" CFLAGS="-mmic"

but I've got the error

> checking for clang... configure: error: in `/home/ips_serdyuk/mono-3.0.1':
> configure: error: cannot run test program while cross compiling

The corresponding fragment of configure is

> CFLAGS="$CFLAGS -g $WARN"
> CFLAGS_FOR_LIBGC="$CFLAGS_FOR_LIBGC -g"
>
> { $as_echo "$as_me:${as_lineno-$LINENO}: checking for clang" >&5
> $as_echo_n "checking for clang... " >&6; }
> if ${mono_cv_clang+:} false; then :

The last test program is compiled with the success:

> [root at node002 Xeon_Phi]# cat clang_test.c
> int main() {
>   #ifdef __clang__
>        return 0;
>   #else
>        return 1;
>   #endif
> }[root at node002 Xeon_Phi]#icc -mmic -o clang_test clang_test.c
> [root at node002 Xeon_Phi]#

Are there any suggestions how to fix above problem?

Thanks.
