Bug ID: 113192
Summary: [14 Regression] ERROR: couldn't execute
"../../../gcc/libgomp/testsuite/flock": no such file
or directory
Product: gcc
Version: 14.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libgomp
Assignee: unassigned at gcc dot gnu.org
Reporter: danglin at gcc dot gnu.org
CC: jakub at gcc dot gnu.org, tschwinge at gcc dot gnu.org
Target Milestone: ---
Host: hppa64-hp-hpux11.11
Target: hppa64-hp-hpux11.11
Build: hppa64-hp-hpux11.11
HP-UX doesn't have flock but it does have perl. configure tries to create
a fallback but a relative path to libgomp/testsuite/flock is generated.
It is wrong when the testsuite is run.
AC_MSG_NOTICE([checking for flock implementation])
AC_CHECK_PROGS(FLOCK, flock)
# Fallback if 'perl' is available.
if test -z "$FLOCK"; then
AC_CHECK_PROG(FLOCK, perl, $srcdir/testsuite/flock)
fi

checking for flock... no

Support parallel testing in libgomp: fallback Perl 'flock' [PR66005]
It appears this problem can be worked around by exporting FLOCK.
