Bug ID: 92553
Summary: OpenMP offload static linking error
Product: gcc
Version: 9.2.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: lto
Assignee: unassigned at gcc dot gnu.org
Reporter: xw111luoye at gmail dot com

Target Milestone: ---
I have a linking error when building miniQMC.
The offload functions are first archived in libqmcwfs.a and then linked to the
final binary.
Recipe:
git clone https://github.com/QMCPACK/miniqmc.git
cd miniqmc
git co OMP_offload
cd build
cmake -D CMAKE_CXX_COMPILER=g++ -D ENABLE_OFFLOAD=1 ..
make -j32 check_spo
