小知识：Facebook Open Platform编译FAQ

1：下载源码：http://developers.facebook.com/fbopen/

2：根据readme的说明，把fbml所需的软件下载到dependencies目录下

3：fbml的php扩展的编译，本身有个脚本，不过一般情况下都不能顺利通过那脚本编译成功

错误提示1:

gconvert.c:48:2: error: #error GNU libiconv not in use but included iconv.h is from libiconv

解决办法：

修改build-all.py

glib-2.14.6.tar.gz: (“./configure”, “make”, “sudo make install”),

改成

glib-2.14.6.tar.gz: (“./configure –with-libiconv=gnu”, “make”, “sudo make install”),

错误提示2：

make: *** [default] Error 2

解决办法：

修改dependencies/mozilla/layout/build/Makefile.inifdef

MOZ_ENABLE_GTK2EXTRA_DSO_LDOPTS += $(MOZ_GTK2_LIBS) \ $(NULL)

改成ifdef MOZ_ENABLE_GTK2EXTRA_DSO_LDOPTS += $(MOZ_GTK2_LIBS) \ -L/usr/X11R6/lib -lX11 -lXrender \ $(NULL)

这个错误一般发生在firefox编译的时候，我一般都手动解压缩firefox软件，然后修改Makefile.in，然后在build-all.py中屏蔽解压缩firefox的语句就行

错误提示3：

In file included from js/jsarena.c:49:

js/jsbit.h:173: error: size of array js_static_assert_line_173 is negative

make[1]: *** [js/jsarena.o] Error 1

make: *** [src] Error 2

解决办法：

修改 src/js/jsbit.h 第173行

S_STATIC_ASSERT(sizeof(unsigned long long) == sizeof(JSUword));

改成

S_STATIC_ASSERT(sizeof(unsigned long) == sizeof(JSUword));

这个错误发生在firefox编译成功后，进行fbml的编译时候发生的，如果你用build-all.py编译，不想进行前面的编译，可以根据脚本屏蔽前面的编译。
