Getting a gcc include error trying to build vector-add example for FPGA emulation using OneAPI on my local server.

Hi John, thanks for responding.

My steps were as follows:

* open a terminal window

* download OneAPI base toolkit from https://software.intel.com/en-us/oneapi/base-kit:

* under 'download the toolkit' selected 'get it now'

* chose Linux, chose Online Installer, downloaded l_BaseKit_b_2021.1.5.720.tar.gz

* tar xvf l_BaseKit_b_2021.1.5.720.tar.gz

* module load gcc/8.3.0

* in l_BaseKit: ./install.sh --tmp-dir ../tmp

* download FPGA add-on from https://dynamicinstaller.intel.com/oneapi/toolkits/base-kit/linux/ -- "Intel® FPGA Add-on for oneAPI Base Toolkit"

* tar xvf intel-fpga-addon-for-oneapi-base-kit-for-a10gx-linux.zip

* in addon l_intel subdirectory: ./setup.sh --install-dir /.alpha/public/inteloneapi --tmp-dir ../../tmp

The possibly-relevant entries in my environment (from running 'env' as you suggested):

Thanks for any advice!

One additional clue (perhaps) from today. My colleague sent me the following:

In Makefile.fpga I replaced the following line:

CXX := dpcpp

with:

CXX := dpcpp --gcc-toolchain=/.alpha/public/opt/gcc-8.3.0

That got rid of the include file complaints, but added the new complaint

"Error: No recognized input file format on the command line".

Not sure whether it actually fixed the original problem and allowed the process to hit the next problem, or just caused a new problem to occur before the old problem could actually be encountered.

The only reason I have for thinking it's the first rather than the second is that while the commands

clang -x c -v -E /dev/null

and

dpcpp -x c -v -E /dev/null

both produce output that includes

"Selected GCC installation: /.alpha/lib/gcc/x86_64-redhat-linux/4.8.5",

the command

dpcpp --gcc-toolchain=/.alpha/public/opt/gcc-8.3.0 -x c -v -E /dev/null

produces output that includes:

"Selected GCC installation: /.alpha/public/opt/gcc-8.3.0/lib/gcc/x86_64-pc-linux-gnu/8.3.0".

Not really sure where to go from here.
