无法直接部署到web，踩坑完毕后发现无法显示页面 #21

我用的编译命令是, 先前已用emsdk_env部署环境 不知是不是和和这个有关，部署其他传统awtk项目就没弹出这个。 |

浏览器里是个受限环境，跑不了httpd服务。通常在嵌入式系统中启用httpd服务，AWTK web通过xml http request去请求httpd，获取数据来显示。 |
那web上无法显示界面的问题如何解决，需要卸掉httpd服务吗？ |
不太清楚你的意思，但我感觉httpd服务跟在web上无法显示应该是无关的，我自己按照mvvm-c-hello的sconstuct配置尝试把awtk-mvvm移植到designer的模版项目运行temperature1的例子，demo在桌面上正常运行，但是部署到web也是同样什么都无法显示。 |

之前 mvvm 没有支持 web。你更新一下 awtk 和 awtk-mvvm，参考下这两个文件：
谢谢 |
|
更新了，尝试部署awtk-mvvm新加的那个build.json，结果报错: |
|
awtk也要更新 |
|
awtk-web build.py里build_awtk_js有办法让它只编译部分未编译的文件吗？ |
|
这次awtk和awtk-mvvm都更新过了。 我按照mvvm_for_web.md里的声明改了application.c，就变成了这种情况。 之前自己移植是修改main.c, 在 #include "mvvm_app.inc"
#define GLOBAL_INIT() mvvm_app_init()
#define GLOBAL_EXIT() mvvm_app_deinit()这样demo程序运行时, 通过GLOBAL_INIT将跳转到mvvm_app_init。 不知道会不会和这个冲突，但是我如果把上面main.c的修改去掉的话scons桌面端是无法运行的。 模版项目目前只根据mvvm_for_web.md改了application.c，build.json如下： 我不知道自己哪个步骤忘搞了。 |
|
上述问题已解决，mvvm_for_web.md的声明需要改改，application.c上对 应该是实现而不是声明，因为没有源文件链接，上面两个函数真正的实现是放在了awtk-mvvm的mvvm_app.inc文件里面，引用不到。 解决方法： 然后再根据【调用 MVVM 初始化和反初始化函数】修改。 |
|
根据mvvm_for_web.md文档的方法，还是无法在浏览器上显示mvvm_c_hello例子的内容，不过awtk designer的模版项目能移植mvvm并且部署到浏览器了。 |
首先提示找不到httpd头文件，在build.json的Includes加入
"../awtk-restful-httpd/src/httpd"解决。然后报错：
原因是httpd.c用的上述函数并没有被include。
在httpd.c加上
报错：
又改为：
解决。
然后编译提示undefined symbol, 继续在build.json添加路径，修改完毕的build.json如下(项目README提到的依赖我是安装在同级目录)：
