Opened: 2006-02-03 06:02 0000
Description:   Opened: 2006-02-03 06:02 0000 
app-emulation/bochs can be built with either an internal debugger or a GDB
stub. The USE flag "debugger" currently enables or disables the internal
debugger, but the GDB stub is never built. It should be, with USE="-debugger".

Makes sense. Committed, thanks

This fix isn't sufficient for -debugger; --disable-smp is also necessary, per
http://bugs.gentoo.org/show_bug.cgi?id=135679

Reopening because as noted, bochs now fails to build with USE=-debugger

this is "fixed" for >=app-emulation/bochs-2.2.6 by never enabling SMP as shown
in the Changelog :

  26 Nov 2006; Luca Barbato <lu_zero@gentoo.org> bochs-2.2.6.ebuild:
  remove smp since it breaks gdb stub

--enable-smp has been validated to work in amd64 when USE="debugger" though

------- Comment #8 From Carlo Marcelo Arenas Belon 2007-09-18 14:42:00 0000 ------- 
starting with >=app-emulation/bochs-2.3.5 for USE="-debugger" smp is now
unconditionally disabled to prevent a build failure as suggested here.

there is no way yet to enable smp for the ebuild (unless it is done only for
USE="debugger") but that is arguably a different bug as there is currently no
way to break the build unless the ebuild is modified, and modified in the wrong
place ;)

The bug is still present in app-emulation/bochs-2.3.7

I've modified the ebuild so that all supported combinations of SMP, GDB stub
and internal debugger can be selected using the flags smp, gdbstub and
debugger.
It disables smp and shows a warning with USE="smp gdbstub" and aborts with an
error message if USE="gdbstub debugger" is used.
This ebuild also fixes the QA warning from #258141.

Ebuild with additional USE flags for selecting SMP, GDB stub and debugger
support
