I'm using a dual Pentium III running a modified Trustix Secure Linux. building mozilla from cvs, I get the following; make[4]: Entering directory `/usr/src/mozilla/widget/src/qt' nsLookAndFeel.cpp c++ -o nsLookAndFeel.o -c -DOSTYPE=\"Linux2.4\" -DOSARCH=\"Linux\" -DMOZ_REFLOW_PERF -DMOZ_REFLOW_PERF_DSP -DOJI -D_IMPL_NS_WIDGET -D_BSD_SOURCE -I../../../dist/include/xpcom -I../../../dist/include/string -I../../../dist/include/gfx -I../../../dist/include/layout -I../../../dist/include/content -I../../../dist/include/dom -I../../../dist/include/gfx2 -I../../../dist/include/appshell -I../../../dist/include/pref -I../../../dist/include/uconv -I../../../dist/include/widget -I../../../dist/include -I/usr/src/mozilla/dist/include/nspr -I/usr/include -I/usr/include -I/usr/include -I./../xpwidgets -I. -I../../../gfx/src/qt -I/usr/X11R6/include -fPIC -I/usr/X11R6/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wbad-function-cast -Wcast-align -Woverloaded-virtual -Wsynth -pedantic -Wno-long-long -pipe -pthread -DDEBUG -DDEBUG_root -DTRACING -g -I/usr/local/qt/include -DQT_GENUINE_STR -I/usr/X11R6/include -DMOZILLA_CLIENT -include ../../../config-defs.h -Wp,-MD,.deps/nsLookAndFeel.pp nsLookAndFeel.cpp nsLookAndFeel.cpp: In method `nsresult nsLookAndFeel::GetNavSize(nsILookAndFeel::nsMetricNavWidgetID, nsILookAndFeel::nsMetricNavFontID, int, nsSize &)': nsLookAndFeel.cpp:449: invalid use of undefined type `struct nsSize' ../../../dist/include/widget/nsILookAndFeel.h:45: forward declaration of `struct nsSize' nsLookAndFeel.cpp:450: invalid use of undefined type `struct nsSize' ../../../dist/include/widget/nsILookAndFeel.h:45: forward declaration of `struct nsSize' make[4]: *** [nsLookAndFeel.o] Error 1 make[4]: Leaving directory `/usr/src/mozilla/widget/src/qt' make[3]: *** [install] Error 2 make[3]: Leaving directory `/usr/src/mozilla/widget/src' make[2]: *** [install] Error 2 make[2]: Leaving directory `/usr/src/mozilla/widget' make[1]: *** [install] Error 2 make[1]: Leaving directory `/usr/src/mozilla' make: *** [build] Error 2

Disabling debug removes the problem, mozilla compiles happily, but won't start... mortenn@dr_p /usr/src/mozilla/dist/bin$ strace -o ~/strace ./mozilla ./run-mozilla.sh ./mozilla-bin MOZILLA_FIVE_HOME=/usr/src/mozilla/dist/bin LD_LIBRARY_PATH=/usr/src/mozilla/dist/bin:/usr/src/mozilla/dist/bin/plugins:/usr/local/qt/lib:/usr/local/qt/lib: LIBRARY_PATH=/usr/src/mozilla/dist/bin:/usr/src/mozilla/dist/bin/components SHLIB_PATH=/usr/src/mozilla/dist/bin LIBPATH=/usr/src/mozilla/dist/bin ADDON_PATH=/usr/src/mozilla/dist/bin MOZ_PROGRAM=./mozilla-bin MOZ_TOOLKIT= moz_debug=0 moz_debugger= /usr/src/mozilla/dist/bin/run-mozilla.sh: line 72: 20338 Aborted $prog ${1+"$@"} attaching output of strace

Duplicated the build problem. Looks like the forward declaration of 'struct nsSize' in http://lxr.mozilla.org/seamonkey/source/widget/public/nsILookAndFeel.h isn't good enough when actually implementing code that uses it. The fix appears to be just replacing the forward declaration with a #include "nsSize.h" . The crash on startup problem could be a number of things. Knowing the exact build config would help narrow the choices. Also, try generating a backtrace using gdb. I can't deduce anything from the strace.

I'll need to install gdb, but in the meantime here's some info about my system: Dual P-III 700 384 MB PC100 RAM running on a trustix 1.5 with everything the build page said I needed plus an upgraded OpenSSL which I did need, but the page didn't mention. (had OpenSSH 1.x)

okay... just how do I make a backtrace? I've never used gdb before (I have version 5.0)

Which mozilla build options did you use? See http://www.mozilla.org/unix/debugging-faq.html for info about using gdb.

mortenn@dr_p ~$ cat /root/.mozconfig # sh # Build configuration script # # See http://www.mozilla.org/build/unix.html for build instructions. # # Options for client.mk. # Options for 'configure' (same as command-line options). ac_add_options --disable-accessibility #ac_add_options --disable-debug #ac_add_options --enable-strip-libs ac_add_options --enable-crypto ac_add_options --enable-mathml ac_add_options --enable-svg ac_add_options --with-gtk ac_add_options --with-xlib ac_add_options --with-qt ac_add_options --with-jpeg=/usr ac_add_options --with-zlib=/usr ac_add_options --with-png=/usr I'm reading the debug-faq, but I haven't found anything regarding a backtrace yet...

Ok, with those configure options, the crash on startup is probably due to bug 91829. Mozilla cannot run with multiple toolkit components installed at once. Remove the unwanted toolkit libs or only configure with a single toolkit rm -f dist/bin/components/*_xlib.so rm -f dist/bin/components/*_qt.so

Comment on attachment 53218 [details] [diff] [review] Keep forward decl & add #include to file that actually uses class r=pavlov

Patch 53218 has been checked in.

eek! Please don't |#ifdef| |#include|s. See http://mozilla.org/hacking/portable-cpp.html#dont_ifdef_include .

Opened a new bug on my segfault... Bug 105190
