I've come across a few RPMS with missing debuginfo and wasted a great
deal of time trying to rebuild to get the debuginfo.
The problem seems to be that some ant scripts force debugging to be
off or perhaps inherited from a property that no-one remembered to
set. This is compounded by the fact that some ant scripts unzip source
archives and then call ant recursively to build them: in such a case
it's very hard to patch build.xml to force debugging=true.
This patch for ecj forces debuginfo always to be generated while
rebuilding an RPM, no matter what ant thinks. I realize it's
something of a kludge, but it's better than the current situation.
When compiling C/C++/etc, RPM passes "-g" in RPM_OPT_FLAGS. An
alternative to this patch might be to scan RPM_OPT_FLAGS for "-g" and
only turn on debugging if it's present. However, I doubt that in
practice it'd make any difference.
Andrew.
