DwTag[] tagEncodings = DwTag.values(); ^ ../../frysk-sys/lib/dwfl/DwarfDieFactory.java:82: error: Type ‘DwTag’ not found in the declaration of the local variable ‘tag’.

This is expressed in .java.h implicit rule. But to build .class files, compiler needs DwTag.java and other files... and this dependency isn't stated in Makefile. -- Summary: Missing foo.h: bar.java dependencies in build system Product: frysk Version: unspecified Status: NEW Severity: normal Priority: P2 Component: general AssignedTo: frysk-bugzilla at sourceware dot org ReportedBy: pmachata at redhat dot com GCC build triplet: x86_64-unknown-linux-gnu GCC host triplet: x86_64-unknown-linux-gnu GCC target triplet: x86_64-unknown-linux-gnu OtherBugsDependingO 1600 nThis: http://sourceware.org/bugzilla/show_bug.cgi?id=5074 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
