已经想过很多方法,其中之一在/opt/src/mozilla-1.9.2/toolkit/library/Makefile,
+EXTRA_DSO_LDOPTS += -lexpat -lfreetype $(FT2_LIBS) 

但都不奏效.最好是编译成功提供一下思路.

undefined reference to `FcFreeTypeCharIndex(FT_FaceRec_*, unsigned int)' 

还是说缺程序库的问题
链接的时候才报的错
安装libfontconfig相关的库试试

还真的没有自己编译软件包，rpm习惯了

这个······


只有编译过了的同志才知晓。

没有从源码按过这个东西
如果可能的话  通过rpm包 或则yum等等这些方式安装吧 

没编译过，不敢打妄语

 firefox 不是java写的吗？

 可能之用到了那3个函数在静态库中。

没准那3个函数是新出来的
