Hi rtld masters! I'm restructuring linuxpluginwraapper by supporting ELF symbol versioning. I noticed that there are some problems. 1. I'll never try to support Flash6, and I'll support Flash7. Because Flash6 required some old(2.0.x) freetype2 functions. I tried to make a compat functions, and noticed that I cannot care these functions:-(. *NOTE* This isn't a issue caused by ELF symbol versioning. *NOTE* 2. "T" (the symbol is in the text (code) section) symbol cannot be resolved like following behavior. $ firefox /home/nork/Flash/AYB2.swf LoadPlugin: failed to initialize shared library /usr/X11R6/lib/linux-flashplugin7/libflashplayer.so [/usr/X11R6/lib/linux-flashplugin7/libflashplayer.so: Undefined symbol "_ZN12NetworkASyncD1Ev"] (NOTE)_ZN12NetworkASyncD1Ev = NetworkASync::~NetworkASync() $ nm -DC /usr/X11R6/lib/linux-flashplugin7/libflashplayer.so (snip) 000677e0 T NetworkASync::~NetworkASync() (snip) $ elfdump /usr/X11R6/lib/linux-flashplugin7/libflashplayer.so (snip) entry: 757 st_name: _ZN12NetworkASyncD1Ev st_value: 0x677e0 st_size: 33 st_info: STT_FUNC STB_GLOBAL st_shndx: 10 (snip) # I trying to test with $FreeBSD: src/libexec/rtld-elf/rtld.c,v 1.109 2005/12/18 19:43:32 kan Exp $ linux-flashplugin-7.0r61 FreeBSD nadesico.ninth-nine.com 7.0-CURRENT FreeBSD 7.0-CURRENT #68: Wed Dec 21 20:56:36 JST 2005 nork@nadesico.ninth-nine.com:/usr/obj/usr/src/sys/NADESICO i386 # New codes are in following place: http://people.freebsd.org/~nork/LinuxPluginWrapper.tar.bz2 (NOTE) Alpha-- quality codes, please cd LinuxPluginWrapper/wrappers/browser, and make all install.
