Attempting to build a 32-bit version of Firefox on a Fedora Core 6 system with an AMD 64bit process fails here: c++ -o nsHTMLSharedElement.o -c -I../../../../dist/include/system_wrappers -include /home/wag/mozilla/trunk/config/gcc_hidden.h -DMOZILLA_INTERNAL_API -DOSTYPE=\"Linux2.6.18-1.2869\" -DOSARCH=Linux -DBUILD_ID=2007062214 -D_IMPL_NS_LAYOUT -I../../../../dist/include/xpcom -I../../../../dist/include/string -I../../../../dist/include/gfx -I../../../../dist/include/layout -I../../../../dist/include/widget -I../../../../dist/include/dom -I../../../../dist/include/js -I../../../../dist/include/locale -I../../../../dist/include/unicharutil -I../../../../dist/include/webshell -I../../../../dist/include/uriloader -I../../../../dist/include/htmlparser -I../../../../dist/include/necko -I../../../../dist/include/view -I../../../../dist/include/pref -I../../../../dist/include/docshell -I../../../../dist/include/xpconnect -I../../../../dist/include/xuldoc -I../../../../dist/include/caps -I../../../../dist/include/editor -I../../../../dist/include/imglib2 -I../../../../dist/include/mimetype -I../../../../dist/include/exthandler -I../../../../dist/include/uconv -I../../../../dist/include/intl -I../../../../dist/include/plugin -I../../../../dist/include -I../../../../dist/include/content -I../../../../dist/include/nspr -DMOZ_PNG_READ -DMOZ_PNG_WRITE -I../../../../dist/sdk/include -I/home/wag/mozilla/trunk/content/html/content/src/../../../base/src -I/home/wag/mozilla/trunk/content/html/content/src/../../../events/src -I/home/wag/mozilla/trunk/content/html/content/src/../../../xbl/src -I/home/wag/mozilla/trunk/content/html/content/src/../../../../layout/style -I/home/wag/mozilla/trunk/content/html/content/src -fno-rtti -fno-excepti [wag@localhost ~]$ tail build.out gmake[5]: Leaving directory `/home/wag/mozilla/trunk/fx32-obj/toolkit/airbag' gmake[4]: *** [libs] Error 2 gmake[4]: Leaving directory `/home/wag/mozilla/trunk/fx32-obj/toolkit' gmake[3]: *** [libs_tier_toolkit] Error 2 gmake[3]: Leaving directory `/home/wag/mozilla/trunk/fx32-obj' gmake[2]: *** [tier_toolkit] Error 2 gmake[2]: Leaving directory `/home/wag/mozilla/trunk/fx32-obj' make[1]: *** [default] Error 2 make[1]: Leaving directory `/home/wag/mozilla/trunk/fx32-obj' make: *** [build] Error 2

The cause of this is that exception_handler.cc includes both signal.h and asm/sigcontext.h. However, signal.h includes bits/sigcontext.h. Documentation seems to indicate that you should not include sigcontext.h, but include signal.h instead. I also changed minidump_generator.cc to include stdio.h instead of asm/sigcontext.h. With this patch the build goes to completion, but I have no way of testing if it actually will send correct crash data. I also have no way to test if this will build correctly on a 32 bit processor linux system or on other distributions.

Comment on attachment 269461 [details] [diff] [review] possible fix It's gonna take more than that to make Breakpad work on x86_64, and we don't take patches to Breakpad here, we only take them upstream.

Duping this over, we really just want a patch to disable building Breakpad on x86_64.

The intention of this patch was not to create a 64-bit build with breakpad. The intention was to permit building a 32 bit version of firefox including breakpad but doing the build using the 32-bit build tools on a 64 bit system. Duping it to that bug 385398 is really not correct. That bug is about trying to build a Linux 64-bit binary that includes breakpad, which is really a completely seperate issue. If you don't want to fix this, then it would be more correct to mark it WONTFIX than to dupe it to a bug about something that is really not the same.

Ok, I apparently didn't read your bug right. Sorry! Can you file an issue in Breakpad's issue tracker, and prepare a patch against Breakpad SVN? If we get it in upstream, we can merge back down here. http://code.google.com/p/google-breakpad/issues/list

OK filed issue 190. http://code.google.com/p/google-breakpad/issues/detail?id=190

I think this got fixed when I merged in bug 386632.
