Bug ID: 107631
Summary: many tests don't link on Mac OS X 10.7
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: modula2
Assignee: gaius at gcc dot gnu.org
Reporter: ro at gcc dot gnu.org
CC: iains at gcc dot gnu.org
Target Milestone: ---
Host: x86_64-apple-darwin11.4.2
Target: x86_64-apple-darwin11.4.2
Build: x86_64-apple-darwin11.4.2
After I got gm2 and libgm2 to build on Mac OS X 10.7, test results aren't too
bad:
=== gm2 Summary for unix ===
# of expected passes 11604
# of unexpected failures 108
# of unresolved testcases 66
=== gm2 Summary for unix/-m32 ===
# of expected passes 10380
# of unexpected failures 708
# of unresolved testcases 690
=== gm2 Summary ===
# of expected passes 21984
# of unexpected failures 816
# of unresolved testcases 756
Fortunately, the causes for failure are limited:
