Has anyone managed to build the Firefox-1.5-1 src rpm from the development try under current FC4? I was able to build both the required cairo and nspr src rpms (with a slight mod to avoid the modular X11 changes). However I find that the firefox build fails at... c++ -o nsNativeThemeGTK.o -c -I../../../dist/include/system_wrappers -include .. /../../config/gcc_hidden.h -DNATIVE_THEME_SUPPORT -DMOZILLA_INTERNAL_API -DOSTYP E=\"Linux2.6.14-1\" -DOSARCH=\"Linux\" -DBUILD_ID=0000000000 -DUSE_POSTSCRIPT -I ../.. -I./. -I./.. -I./../shared -I./../x11shared -I/usr/X11R6/include -I/usr/in clude/freetype2 -I/usr/include/freetype2/config -I../../../dist/include/xpcom -I../../../dist/include/string -I../../../dist/include/widget -I../../../dist/i nclude/view -I../../../dist/include/util -I../../../dist/include/pref -I../../.. /dist/include/uconv -I../../../dist/include/unicharutil -I../../../dist/include/ locale -I../../../dist/include/necko -I../../../dist/include/content -I../../../ dist/include/layout -I../../../dist/include/gfx -I../../../dist/include -I/usr/i nclude/nspr4 -I../../../dist/sdk/include -I/usr/X11R6/include -fPIC -I/usr /X11R6/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wca st-align -Woverloa ded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dt or -Wno-long-long -pedantic -fshort-wchar -pthread -pipe -DNDEBUG -DTRIMMED -Os -g -pipe -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -m32 -march=i386 -mtune=pentium4 -fasynchronous-unwind-tables -DXTHREADS -D_REENTRANT -DXUSE_MTSAFE_API -I/usr/i nclude/gtk-2.0 -I/usr/lib/gtk-2.0/include -I/usr/X11R6/include -I/usr/include/at k-1.0 -I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/freetype2 /config -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include -I/usr/X11R6/incl ude -DMOZILLA_CLIENT -include ../../../mozilla-config.h -Wp,-MD,.deps/nsNativeTh emeGTK.pp nsNativeThemeGTK.cpp mozilla-decoder.cpp: In function 'int mozilla_decoders_init()': mozilla-decoder.cpp:211: error: 'pango_cairo_font_map_get_default' was not decla red in this scope gmake[5]: *** [mozilla-decoder.o] Error 1 gmake[5]: *** Waiting for unfinished jobs.... nsFontMetricsPango.cpp: In member function 'virtual PRInt32 nsFontMetricsPango:: GetPosition(const PRUnichar*, PRUint32, nsPoint)': nsFontMetricsPango.cpp:984: warning: suggest parentheses around assignment used as truth value ../../../dist/include/layout/nsIMenuParent.h:101: warning: 'DirectionFromKeyCode _lr_tb' defined but not used ../../../dist/include/layout/nsIMenuParent.h:114: warning: 'DirectionFromKeyCode _rl_tb' defined but not used gmake[5]: Leaving directory `/home/howarth/rhdev/BUILD/mozilla/gfx/src/gtk' gmake[4]: *** [libs] Error 2 gmake[4]: Leaving directory `/home/howarth/rhdev/BUILD/mozilla/gfx/src' gmake[3]: *** [libs] Error 2 gmake[3]: Leaving directory `/home/howarth/rhdev/BUILD/mozilla/gfx' gmake[2]: *** [tier_9] Error 2 gmake[2]: Leaving directory `/home/howarth/rhdev/BUILD/mozilla' gmake[1]: *** [default] Error 2 gmake[1]: Leaving directory `/home/howarth/rhdev/BUILD/mozilla' make: *** [build] Error 2 error: Bad exit status from /var/tmp/rpm-tmp.95074 (%build) Could this be a problem due to the recent upgrade to gcc 4.0.2?
