linux下无法编译成功

１、根据操作文档，在awtk执行，sons后，进入awtk-quickjs下执行scons，提示如下
`
3rd/quickjs/quickjs-libc.c: In function 'js_os_signal':
3rd/quickjs/quickjs-libc.c:1814:5: error: unknown type name 'sighandler_t'

2、通过手动执行quickjs仓库的make，编译后的文件直接copy到awtk-quickjs/lib下，执行scons，依然报错
scons: done reading SConscript files.
scons: Building targets ...
scons: *** [src/c/main.o] UnicodeDecodeError : 'ascii' codec can't decode byte 0xe5 in position 23: ordinal not in range(128)
scons: building terminated because of errors.

具体是什么系统，什么版本？sighandler_t没有定义有点不正常。

ubuntu16.04

[shiyafei]

看C部分代码，是结合xml一起的，quick-js这个暂时不支持xml的吗，只能通过函数来绘制界面？

[xianjimli]

支持XML。
AWTK依赖的库都安装了吗？

安装了

我知道了，原来要定义_GNU_SOURCE。你更新一下试试，谢谢。

我在luban的嵌入式linux编译，也有这个问题，定义_GNU_SOURCE宏，没解决。
