Bug ID: 67002 Summary: [5] [SH]: Bootstrap stage 2/3 comparison failure - gcc/real.o differs Product: gcc Version: unknown Status: UNCONFIRMED Severity: normal Priority: P3 Component: target Assignee: unassigned at gcc dot gnu.org Reporter: glaubitz at physik dot fu-berlin.de CC: doko at gcc dot gnu.org, kkojima at gcc dot gnu.org, olegendo at gcc dot gnu.org Target Milestone: --- Target: sh*-*-* Created attachment 36053 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36053&action=edit gzip-compressed build log of gcc-5 (r225710) on sh4 Hello! After checking with the gcc-5 build logs for the other architectures in Debian which do not exhibit this particular comparison failure, I have decided to file this as a bug against upstream. This particular comparison failure also doesn't show with gcc-4.9, albeit I don't know whether gcc/real.o exist on gcc-4.9. Here is the tail of the build log: INFO=makeinfo --split-size=5000000 --split-size=5000000" compare make[4]: Entering directory '/«PKGBUILDDIR»/build' make[5]: Entering directory '/«PKGBUILDDIR»/build' rm -f stage_current make[5]: Leaving directory '/«PKGBUILDDIR»/build' Comparing stages 2 and 3 warning: gcc/cc1-checksum.o differs warning: gcc/cc1plus-checksum.o differs warning: gcc/cc1obj-checksum.o differs warning: gcc/cc1objplus-checksum.o differs Bootstrap comparison failure! gcc/real.o differs Makefile:20320: recipe for target 'compare' failed make[4]: *** [compare] Error 1 make[4]: Leaving directory '/«PKGBUILDDIR»/build' Makefile:20299: recipe for target 'stage3-bubble' failed make[3]: *** [stage3-bubble] Error 2 make[3]: Leaving directory '/«PKGBUILDDIR»/build' Makefile:20362: recipe for target 'bootstrap' failed make[2]: *** [bootstrap] Error 2 make[2]: Leaving directory '/«PKGBUILDDIR»/build' s=`cat status`; rm -f status; \ if [ $s -ne 0 ] && [ -z "$NO_CONFIG_LOG_DUMP" ]; then \ for log in $(find /«PKGBUILDDIR»/build -name config.log); do \ case "$log" in */prev-*) continue; esac; \ echo LOGFILE START $log; \ cat $log; \ echo LOGFILE END $log; \ done; \ fi; \ test $s -eq 0 LOGFILE START /«PKGBUILDDIR»/build/config.log This file contains any messages produced by compilers while running configure, to aid debugging if configure makes a mistake.
