我正在尝试构建xulrunner版本2.0（从mozilla ftp站点下载的源代码），但在尝试创建libxul.so时，我不断获取一些未定义的引用。我尝试了10.0版，但结果相同。
我在Archlinux上构建，但我也从我从mozilla网站下载的VM上获得了与Ubuntu相同的错误。
在构建xulrunner之前，需要进行一些修改才能构建：
.mozconfig我正在使用：
mk_add_options AUTOCONF=autoconf-2.13
mk_add_options PYTHON=/usr/bin/python2
mk_add_options MOZ_CO_PROJECT=xulrunner
mk_add_options MOZ_OBJDIR=@topsrcdir@/obj-xulrunner
ac_add_options --enable-application=xulrunner
ac_add_options --disable-javaxpcom
大约30分钟后，我在尝试构建libxul.so时遇到了这些错误：
...

用于创建libxul.so的命令行确实包含＆＃39; -lfreetype＆＃39;，当我在libfreetype.so中查找FT_Done_Face函数时，它存在：
[dev400t@arch mozilla-2.0]$ nm --dynamic /usr/lib/libfreetype.so | grep FT_Done_Face
000000000001b300 T FT_Done_Face
我确实添加了＆＃34; -Wl，-t＆＃34;命令行的选项，以确保找到libfreetype.so：找到它。
我错过了什么？
答案 0 :(得分：1)
您的freetype2版本是＆gt; = 2.5.1。它包含此更改http://git.savannah.gnu.org/cgit/freetype/freetype2.git/commit/?id=fae382076409db198dfbff36ac4cbb97b05b30a1，就Firefox而言，它是向后兼容的。
您需要将修复程序从此错误反向移植到源代码树：https://bugzilla.mozilla.org/show_bug.cgi?id=944454或降级您的libfreetype2。
Firefox 26及更高版本（包括24 ESR）的源代码已包含修复程序。
