源代码是什么
说白了就是各种编程语言，你现在所用的源码所有软件都是用各种源代码编出来的，大概样子就像：
<!--STATUS OK--><html><head>
<meta /w.gif?源码大厂面试源码分析q=%D4%B4%B4%FA%C2%EB&"+sQ+"path="+p+"&t="+new Date().getTime(); return true}

Facebook Open Platform编译FAQ
1：下载源码：/fbopen/
2：根据readme的说明，把fbml所需的源码软件下载到dependencies目录下
3：fbml的php扩展的编译，本身有个脚本，源码mkl源码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::2: error: #error GNU libiconv not in use but included iconv.h is 源码ijkplayerview源码from libiconv
解决办法：
修改build-all.py
'glib-2..6.tar.gz': ("./configure", "make", "sudo make install"),
改成
'glib-2..6.tar.gz': ("./configure --with-libiconv=gnu", "make", "sudo make install"),
错误提示2：

gmake[1]: Leaving directory `/usr/home/yunfeng/facebook/facebook/fb-open-platform/libfbml-1.2.0/dependencies/mozilla'
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/XR6/lib -lX -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，源码然后修改Makefile.in，源码然后在build-all.py中屏蔽解压缩firefox的源码语句就行
错误提示3：
In file included from js/jsarena.c::
js/jsbit.h:: error: size of array 'js_static_assert_line_' is negative
make[1]: *** [js/jsarena.o] Error 1
make: *** [src] Error 2
解决办法：
修改 src/js/jsbit.h 第行
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的源码编译时候发生的，如果你用build-all.py编译，源码不想进行前面的源码编译，可以根据脚本屏蔽前面的源码gammalab 源码编译。
