今天我可以成功交叉编译arm6版的godot 3.5.1无tools版，可以在trimui smart pro上运行。
编译方法大概是这样（虽然有一个链接问题未完全解决）：
（1）去掉platform/frt/SCsub中关于FRT_PKG_CONFIG的调用，换成frt_env.Append
（2）确保交叉工具链的/usr/include文件夹只包含很少文件，
避免和godot内的库版本不同而编译失败
（3）libvpx有一处获取CPU特性的代码，我改成返回0
（4）用scons交叉编译，通过frt_arch和CCFLAGS和LINKFLAGS指定交叉编译参数，
用PATH环境变量导入gcc程序目录
关于godot mono，上次说的动态AddChild和Instantiate，我没有详细研究，
其实我目前看到有两种动态Instantiate实例化的写法，都是基于
PackedScene.Instantiate（可以强制转换返回值，或者使用泛型类型参数）。
这两种写法区别在于，一种是需要(PackedScene)ResourceLoader.Load("res://tscn路径")
获取PackedScene对象，然后再实例化（感觉像是写ActionScript3），
还有一种是在C井中用Export标注来导出属性，然后在godot编辑器-检查器-修改这个属性指定场景，
从而获取PackedScene对象，然后再PackedScene.Instantiate实例化。
相对而言第一种写法可以没那么依靠godot编辑器，更依靠于字符串，
而不需要手工绑定到tscn场景文件

## [WIP] Cross compiling PPSSPP 1.5.4 debug version to avoid crashing when running imouto.iso homebrew (not by me) softwares or games
* PC version build, don't download zip/tar.gz from github
$ git clone https://github.com/hrydgard/ppsspp
$ cd ppsspp
$ git checkout v1.5.4
$ git submodule update --init
$ mkdir build
$ cd build
$ cmake ..
(modify CMakeCache.txt CMAKE_BUILD_TYPE:STRING=Debug)
$ cmake ..
$ make -j8
$ ./PPSSPPSDL
* https://www.petrockblock.com/forums/topic/guide-to-succefully-compile-ppsspp/
* imouto.iso
* ppsspp_v1.5.4_min.tar.gz
* CMAKE_BUILD_TYPE:STRING=Debug
```
ppsspp闪退好像是因为一个函数sceMpegAvcDecode出问题，不过可能升级到最新版就会没事，
问题是我不会编译这个，等以后有时间再研究
我试过可以很容易在xubuntu 20下编译PC版linux版的PPSSPP，前提是要
git submodule update --init，如果不做子模块导出的话，
直接cmake会提示错误，简单来说就是不能下官方的zip源码包，
而是应该检出tag版本，例如git checkout v1.5.4，
最好预留两三G的硬盘，然后直接cmake和make即可编译成功
——可能只是用了一下OpenGL和SDL2的系统库，其他大多数库都是静态链接的
关于linux掌机跑psp自制游戏会闪退的问题，我现在可以在xubuntu 20下
编译PPSSPP 1.5.4版并且正确运行会在linux掌机上闪退的自制游戏
（这个移植游戏不是我做的）——事实上我编译默认release版，
跑这个游戏也会闪退，只不过我找到解决办法，
就是把CMakeCache.txt的CMAKE_BUILD_TYPE的值改成debug（默认空白），
然后再编译一次即可，体积会增加一倍，但好处是不会出现闪退的情况。
当然这只是对于1.5.4版而言，最新版估计也能用类似的方法解决
