If, for example, GCC is configured such that 'libgomp-plugin-nvptx.so.1'
dynamically links against 'libcuda.so.1', but testing is run on a system where
there is no 'libcuda.so.1', this produces output such as:
PASS: libgomp.oacc-fortran/error_stop-1.f -DACC_DEVICE_TYPE_host=1 -DACC_MEM_SHARED=1 -foffload=disable -O0 (test for excess errors)
PASS: libgomp.oacc-fortran/error_stop-1.f -DACC_DEVICE_TYPE_host=1 -DACC_MEM_SHARED=1 -foffload=disable -O0 execution test
FAIL: libgomp.oacc-fortran/error_stop-1.f -DACC_DEVICE_TYPE_host=1 -DACC_MEM_SHARED=1 -foffload=disable -O0 output pattern test, is CheCKpOInT
libgomp: while loading libgomp-plugin-nvptx.so.1: libcuda.so.1: cannot open shared object file: No such file or directory
ERROR STOP
Error termination. Backtrace: [...]
, should match CheCKpOInT(
|
|^M)+ERROR STOP (
|
|^M)+Error termination.*
..., where after 'CheCKpOInT' we got 'libgomp: while loading [...]' injected
before the expected 'ERROR STOP'.
