You just need to add the library containing the missing symbols (-lXft) to your link line for your executable. Make sure that it comes _after_ the reference to the library that uses them. Thanks, Lyle -----Original Message----- From: gcc-help-owner@xxxxxxxxxxx [mailto:gcc-help-owner@xxxxxxxxxxx] On Behalf Of Bahadir Balban Sent: Thursday, December 16, 2004 10:51 AM To: gcc-help@xxxxxxxxxxx Subject: linking question - can objects in static archive refer to shared libs? Hi, I am building an executable that links with various libraries. One of these libraries is a static one named libgfx_gtk.a. This is created from various object files as below. arm-linux-ar cr libgfx_gtk.a nsDrawingSurfaceGTK.o nsFontMetricsXft.o nsRegionGTK2.o nsNativeThemeGTK.o ... arm-linux-ranlib libgfx_gtk.a 2 of the object files above, refer to shared library symbols in libXft.so. Objects and the archive both compile fine. Is it reasonable to have a static archive with objects that have references to shared symbols like this? Because when I build an executable that links with this static archive, I get undefined references as below: /dist/lib/components/libgfx_gtk.a(nsFontMetricsXft.o)(.text._ZN16nsFontM etricsXft16DrawUnknownGlyphEjiiP9_XftColorP8_XftDraw+0x6c): In function `nsFontMetricsXft::DrawUnknownGlyph(unsigned int, int, int, _XftColor*, _XftDraw*)': : undefined reference to `XftDrawRect' XftDrawRect is a symbol exported from X11 library libXft.so.1.Also note that this complaint is from the libgfx_gtk.a archive, rather than the actual executable being linked. Below is my command to compile my executable. What should I do to resolve these undefined references? (My X11 libs are in a seperate directory but normally they are successfully found by the linker) arm-linux-gcc -I/opt/toolchain/arm-linux/local/include -I/opt/toolchain/arm-linux/local/X11R6/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -pthread -pipe -DNDEBUG -DTRIMMED -ffunction-sections -Os -I/opt/toolchain/arm-linux/local/include/gtk-2.0 -I/opt/toolchain/arm-linux/local/lib/gtk-2.0/include -I/opt/toolchain/arm-linux/local/include/atk-1.0 -I/opt/toolchain/arm-linux/local/include/pango-1.0 -I/opt/toolchain/arm-linux/local/X11R6/include -I/opt/toolchain/arm-linux/local/include/glib-2.0 -I/opt/toolchain/arm-linux/local/lib/glib-2.0/include -o TestGtkEmbed TestGtkEmbed.o -L/opt/toolchain/arm-linux/local/lib -L../../../../dist/bin -L../../../../dist/lib -lgtkembedmoz -L/opt/toolchain/arm-linux/local/X11R6/lib -lX11 -ldl -lm -lsupc++ -L../../../../dist/lib/components -lcaps -lchrmlite -lcookie -ldocshell -leditor -lembedcomponents -lgfx_gtk -lgklayout -lgkplugin -lhtmlpars -li18n -limglib2 -ljar50 -lnecko -lnsappshell -lpref -luconv -lwebbrwsr -lwidget_gtk2 -lxpconnect -lunicharutil_s -lucvutil_s -ljsj -lgtkxtbin -lgfxshared_s -lgkgfx -L../../../../dist/lib/components -L../../../../dist/lib -lmozpng -L../../../../dist/lib -lmozjpeg -L../../../../dist/lib -lmozz -L/opt/toolchain/arm-linux/local/X11R6/lib -lXt -lSM -lICE -L../../../../dist/bin -lmozjs -L../../../../dist/bin -lxpcom -L../../../../dist/bin -L/opt/mozilla_build/mozilla/dist/lib -lplds4 -lplc4 -lnspr4 -L/opt/toolchain/arm-linux/local/lib -Wl,--export-dynamic /opt/toolchain/arm-linux/local/X11R6/lib/libXext.so.6 -lXext -L/opt/toolchain/arm-linux/local/lib -lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lpangox-1.0 -lpango-1.0 -lgobject-2.0 -lgmodule-2.0 -ldl -lglib-2.0 -lm Also here is how I compile the object file with X11 symbol references. arm-linux-gcc -o nsFontMetricsXft.o -c -DNATIVE_THEME_SUPPORT -DXPCOM_TRANSLATE_NSGM_ENTRY_POINT=1 -DOSTYPE=\"Linux\" -DOSARCH=\"Linux\" -I../.. -I./. -I./.. -I./../shared -I./../freetype -I./../x11shared -I/opt/toolchain/arm-linux/local/X11R6/include -I/opt/toolchain/arm-linux/local/X11R6/include/freetype2 -I../../../dist/include/xpcom -I../../../dist/include/string -I../../../dist/include/widget -I../../../dist/include/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/dom -I../../../dist/include/layout -I../../../dist/include/imglib2 -I../../../dist/include/gfx -I../../../dist/include -I/opt/mozilla_build/mozilla/dist/include/nspr -I/opt/toolchain/arm-linux/local/X11R6/include -I/opt/toolchain/arm-linux/local/include -I/opt/toolchain/arm-linux/local/X11R6/include -fno-rtti -fno-exceptions -Wall -Wconversion -Wpointer-arith -Wcast-align -Woverloaded-virtual -Wsynth -Wno-ctor-dtor-privacy -Wno-non-virtual-dtor -Wno-long-long -pthread -pipe -DNDEBUG -DTRIMMED -ffunction-sections -Os -I/opt/toolchain/arm-linux/local/include/gtk-2.0 -I/opt/toolchain/arm-linux/local/lib/gtk-2.0/include -I/opt/toolchain/arm-linux/local/include/atk-1.0 -I/opt/toolchain/arm-linux/local/include/pango-1.0 -I/opt/toolchain/arm-linux/local/X11R6/include -I/opt/toolchain/arm-linux/local/include/glib-2.0 -I/opt/toolchain/arm-linux/local/lib/glib-2.0/include -I/opt/toolchain/arm-linux/local/include -I/opt/toolchain/arm-linux/local/X11R6/include -DMOZILLA_CLIENT -include ../../../mozilla-config.h -Wp,-MD,.deps/nsFontMetricsXft.pp nsFontMetricsXft.cpp Many Thanks, Bahadir
