activating offload.

[Alin Marin Elena]

Hi All,

I have been trying with little success to build and use the gcc 5
snapshots 2015-02-22 and 2015-03-01 with offload support for xeon phi

the build in itself is successfull, I use gcc 4.9.2

install_dir=/ichec/packages/gcc/5.0.0-s20150301

mkdir -p build-fionn-phi
pushd build-fionn-phi
rm -rf *
../configure --build=x86_64-intelmicemul-linux-gnu
--host=x86_64-intelmicemul-linux-gnu \
--target=x86_64-intelmicemul-linux-gnu
--enable-as-accelerator-for=x86_64-suse-linux \
--with-pkgversion=ichec --enable-languages=c,c++,fortran --disable-libgcj \
--enable-__cxa_atexit --enable-libstdcxx-allocator=new  --prefix=$install_dir

make -j20
make install
popd
mkdir -p build-fionn-host
pushd build-fionn-host
rm -rf *

../configure --enable-languages=c,c++,fortran \
--enable-__cxa_atexit --enable-libstdcxx-allocator=new --with-pkgversion=ichec \
--disable-libgcj --build=x86_64-suse-linux --host=x86_64-suse-linux \
--enable-offload-targets=x86_64-intelmicemul-linux-gnu=$install_dir/
--prefix=$install_dir

make -j 20
make install
popd


I set up the environment(I use modules)
set base  /ichec/packages/$PKG/$VER
prepend-path PATH $base/bin
prepend-path LD_LIBRARY_PATH $base/lib
prepend-path LD_LIBRARY_PATH $base/lib64
prepend-path LD_LIBRARY_PATH $base/lib/gcc/x86_64-suse-linux/lib
prepend-path LD_LIBRARY_PATH $base/lib/gcc/x86_64-suse-linux/lib64
prepend-path LD_LIBRARY_PATH $base/lib/gcc/x86_64-intelmicemul-linux-gnu/5.0.0
prepend-path LD_LIBRARY_PATH /ichec/packages/gmp/5.1.2/lib
prepend-path LD_LIBRARY_PATH /ichec/packages/mpfr/3.1.2/lib
prepend-path LD_LIBRARY_PATH /ichec/packages/mpc/1.0.1/lib
prepend-path LIBRARY_PATH /ichec/packages/gmp/5.1.2/lib
prepend-path LIBRARY_PATH /ichec/packages/mpfr/3.1.2/lib
prepend-path LIBRARY_PATH /ichec/packages/mpc/1.0.1/lib
prepend-path LIBRARY_PATH  $base/lib/gcc/x86_64-suse-linux/lib64
prepend-path LIBRARY_PATH  $base/lib/gcc/x86_64-suse-linux/lib
prepend-path CPATH $base/include
prepend-path CPATH /ichec/packages/gmp/5.1.2/include
prepend-path CPATH /ichec/packages/mpfr/3.1.2/include
prepend-path CPATH /ichec/packages/mpc/1.0.1/include
prepend-path FPATH /ichec/packages/mpfr/3.1.2/include
prepend-path FPATH /ichec/packages/gmp/5.1.2/include
prepend-path FPATH /ichec/packages/mpc/1.0.1/include
prepend-path FPATH $base/include
prepend-path INCLUDE /ichec/packages/gmp/5.1.2/include
prepend-path INCLUDE /ichec/packages/mpfr/3.1.2/include
prepend-path INCLUDE /ichec/packages/mpc/1.0.1//include
prepend-path MANPATH $base/shared/man

then I try to build a very simple offload c code
https://sites.google.com/site/alinmelena/coding/xeon-phi/hello_v2-c

gcc -o hello_v2.X hello_v2.c -fopenmp
mkoffload-intelmic: fatal error: offload compiler
x86_64-suse-linux-accel-x86_64-intelmicemul-linux-gnu-gcc not found
compilation terminated.
lto-wrapper: fatal error:

r
eturned 1 exit status
compilation terminated.
/usr/bin/ld: lto-wrapper failed
collect2: error: ld returned 1 exit status

Any idea what I am doing wrong?
regards,
Alin
