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.
