嵌入式Linux运行官方的demoui可以进入函数main_loop_init，运行部署的项目却无法进入函数main_loop_init

[zyafly]

我用的是Ubuntu18.04，平台是全志R528-s3

1.在“awtk-linux-fb/awtk-port/main_loop_linux.c”加入以下打印信息：

  main_loop_t* main_loop_init(int w, int h) {
  main_loop_simple_t* loop = NULL;

log_debug("\n++++++++++12213132132313+++++++\n");
#ifdef WITH_LINUX_EGL
  lcd_egl_context_t* lcd = lcd_linux_egl_create(FB_DEVICE_FILENAME);
#elif WITH_LINUX_DRM
  lcd_t* lcd = lcd_linux_drm_create(DRM_DEVICE_FILENAME);
#else
  lcd_t* lcd = lcd_linux_fb_create(FB_DEVICE_FILENAME);
#endif

  return_value_if_fail(lcd != NULL, NULL);

#ifdef WITH_LINUX_EGL
#else
  native_window_raw_init(lcd);
#endif

  loop = main_loop_simple_init(lcd->w, lcd->h, NULL, NULL);
  loop->base.destroy = main_loop_linux_destroy;

#ifdef HAS_TSLIB

  s_ts_thread =
      tslib_thread_run(TS_DEVICE_FILENAME, input_dispatch_to_main_loop, loop, lcd->w, lcd->h);
#endif /*HAS_TSLIB*/
log_debug("\n+++++++++++++++++\n");
  s_kb_thread =
      input_thread_run(KB_DEVICE_FILENAME, input_dispatch_to_main_loop, loop, lcd->w, lcd->h);
  s_mice_thread =
      mouse_thread_run(MICE_DEVICE_FILENAME, input_dispatch_to_main_loop, loop, lcd->w, lcd->h);
log_debug("\n---------------------------\n");


  atexit(on_app_exit);

  return (main_loop_t*)loop;
}

2.按移植流程，在“awtk-linux-fb”文件夹中执行“scons”->"sh ./release.sh"->拷到开发板解压->运行"./release/bin/demoui"，可以打印以下信息

---------------------------

3.我编译自己的项目，在“awtk-linux-fb”文件夹中执行“scons APP=../user_apps/awtkdemo2”->"./release.sh ../user_apps/awtkdemo2/res demo"->拷到开发板解压->运行"./release/bin/demo"，可以打印以下信息

请问是我哪里搞错了吗？

把代码贴上来看看。

把代码贴上来看看。

我看了官方例程根目录下的“SConstruct”，代码如下
`import os
import scripts.app_helper as app

ARGUMENTS['SHARED'] = 'False'
ARGUMENTS['IDL_DEF'] = 'False'
helper = app.Helper(ARGUMENTS)
helper.call(DefaultEnvironment)

SConscriptFiles = ['src/SConscript']
SConscript(SConscriptFiles)`

把ARGUMENTS['SHARED'] = 'False' ARGUMENTS['IDL_DEF'] = 'False'贴到我部署项目的“SConstruct”，代码如下：

`import os
import scripts.app_helper as app

ARGUMENTS['SHARED'] = 'False'
ARGUMENTS['IDL_DEF'] = 'False'

CUSTOM_WIDGET_LIBS = [{
"root" : '3rd/awtk-widget-rlottie-main',
'shared_libs': ['rlottie'],
'static_libs': []
},
{
"root" : '3rd/awtk-widget-table-view',
'shared_libs': ['table_view'],
'static_libs': []
}]

DEPENDS_LIBS = CUSTOM_WIDGET_LIBS + []

helper = app.Helper(ARGUMENTS)
helper.set_deps(DEPENDS_LIBS)

app.prepare_depends_libs(ARGUMENTS, helper, DEPENDS_LIBS)
helper.call(DefaultEnvironment)

SConscriptFiles = ['src/SConscript', 'tests/SConscript']
helper.SConscript(SConscriptFiles)`

之后就正常了，我请问一下，这脚本“SConstruct”中这些是什么意思？

你最好用designer创建项目，不需要了解这些东西。

使用designer创建的项目放到Ubuntu编译，就会出现上述说的问题，已经试过了全志R528和sigmastart 的ssd201，均需要修改SConstruct脚本文件
