gfortran and libgomp tests do not link the just-built libraries when "make check" is run unless the libraries are first installed in $prefix/lib.
This results in the following differences in the reported error rate for gfortran: Testing after running make install: < # of expected passes 14014 < # of unexpected failures 33 Testing without running make install: > # of expected passes 13143 > # of unexpected failures 824 For libgomp: Testing after running make install: < # of expected passes 1075 < # of unexpected failures 205 Testing without running make install: > # of expected passes 963 > # of unexpected failures 317 The results after make install, with two patches installed, can be found at http://gcc.gnu.org/ml/gcc-testresults/2006-08/msg01383.html -- Summary: "make install" required before testing libgomp and gfortran Product: gcc Version: 4.2.0 Status: UNCONFIRMED Severity: normal Priority: P3 Component: testsuite AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: lucier at math dot purdue dot edu GCC build triplet: powerpc-apple-darwin8.7.0 GCC host triplet: powerpc-apple-darwin8.7.0 GCC target triplet: powerpc-apple-darwin8.7.0 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28913
