      总结

      在使用OK536N-C的sdk搭建环境时总体是非常顺利的，只是qt_demo折腾了一下。希望飞凌的团队能看到并更新SDK压缩包.

      PC准备开发环境

      先下载到源码

      OKT536-linux-sdk.tar.bz2比较大，被分成了6个子压缩包：

      truedei@truedei-code:1-源码$ ls -l
总计 10747185
-rwxrwxrwx 1 root root        372  5月 16 20:48 md5sum.txt

truedei@truedei-code:1-源码$

      如果你害怕搞没，不想重新下载的话，可以先备份下：

      truedei@truedei-code:1-源码$ cd ..
truedei@truedei-code:2-镜像及源码$ cp -arf 1-源码 1-源码_bak

      可以使用md5sum校验：

      truedei@truedei-code:1-源码$ cat md5sum.txt

      解压多个被分割的压缩包时，需要先合并：

      cat OKT536-linux-sdk.tar.bz2.0* > OKT536-linux-sdk.tar.bz2

      然后解压tz2:

      bunzip2 OKT536-linux-sdk.tar.bz2

#得到：
22G  5月 16 21:40 OKT536-linux-sdk.tar

      会得到.tar，再继续解压.tar：

      tar -xvf OKT536-linux-sdk.tar

      解压完整个目录22G：

      truedei@truedei-code:1-源码$ du -sh OKT536-linux-sdk
22G	OKT536-linux-sdk
truedei@truedei-code:1-源码$

      然后拷贝不是中文的目录：例如我的：/media/truedei/soft/Ok536N-C

      truedei@truedei-code:1-源码$ cp -arf OKT536-linux-sdk ../../../../

      我是觉得解压一次不容易，还是cp过去一份比较好，虽然多占了22GB的空间，但是相对安全，例如某个操作破坏了当前的sdk内容，你还可以节省前面所有的操作。

      初探经验：最好赋予下权限，不然build.sh时会报权限不足：

      truedei@truedei-code:OKT536-linux-sdk$ chmod o+w ./ -R
truedei@truedei-code:OKT536-linux-sdk$

      调用时报：

      /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/build/mkcmd.sh: line 750: python: command not found

      原因是我系统中只有python3,没有低版本的python

      ubuntu24.04这样解决：

      sudo apt install python-is-python3

      先编译配置：

      sudo ./build.sh config

      然后直接执行./build.sh编译

      truedei@truedei-code:OKT536-linux-sdk$ ./build.sh

You seem to have the current working directory in your
LD_LIBRARY_PATH environment variable. This doesn't work.
make[1]: *** [support/dependencies/dependencies.mk:27: dependencies] Error 1

truedei@truedei-code:OKT536-linux-sdk$

      LD_LIBRARY_PATH environment variable. This doesn't work.

      说我的环境中存在LD_LIBRARY_PATH变量。

      先临时解决下：

      truedei@truedei-code:OKT536-linux-sdk$ echo $LD_LIBRARY_PATH 
/home/truedei/local/lib:
truedei@truedei-code:OKT536-linux-sdk$ 
truedei@truedei-code:OKT536-linux-sdk$ export LD_LIBRARY_PATH=""
truedei@truedei-code:OKT536-linux-sdk$ echo $LD_LIBRARY_PATH 

truedei@truedei-code:OKT536-linux-sdk$

      为了节省时间，这次可以单独编译rootfs:

      因为我遇到了权限问题，所以加了sudo

      truedei@truedei-code:OKT536-linux-sdk$ sudo ./build.sh buildroot_rootfs

      成功之后是这样的：

      media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/buildroot-202205
build auto finish

      我还发现了一个问题，在编译qt_demo时，Makefile中的qmake路径是写死的：

      cd browser/ && ( test -e Makefile || /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/qmake -o Makefile /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/forlinx/qt_demo/browser/browser.pro ) && make -f Makefile 
cd backlight/ && ( test -e Makefile || /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/qmake -o Makefile /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/forlinx/qt_demo/backlight/backlight.pro ) && make -f Makefile

      报错的路径：

      /home/yy/work/T536/.release/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/qmake

      正确的路径：

      /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/qmake

      导致该问题的原因：

      现在我在刚解压过的原始sdk中，没做过任何编译：

      truedei@truedei-code:qt_demo$ pwd
/media/truedei/soft/Ok536N-C/doc/OK536x-C_Linux5.10.198+Qt5.15.8_用户资料_R1/2-镜像及源码/1-源码/OKT536-linux-sdk/buildroot/package/auto/forlinx/qt_demo
truedei@truedei-code:qt_demo$

      发现已经生成了.qmake.stash和Makefile:

      truedei@truedei-code:qt_demo$ ls -alh

      随便打开一个Makefile看下心里就有数了：

      70d4366b-757d-4e42-9eda-0425200ac748-image.png

      排查的最终解决方案：

      清理掉qt_demo的所有Makefile和.qmake.stash。

      truedei@truedei-code:qt_demo$ find ./ -name "Makefile"
./4g/Makefile
./adc/Makefile
./backlight/Makefile
./books/Makefile
./browser/Makefile

truedei@truedei-code:qt_demo$ 


###删除：
truedei@truedei-code:qt_demo$ find ./ -name "Makefile" -delete
truedei@truedei-code:qt_demo$ find ./ -name "Makefile"
truedei@truedei-code:qt_demo$ 
truedei@truedei-code:qt_demo$ 
###删除qmake的缓存
truedei@truedei-code:qt_demo$ rm -rf .qmake.stash
truedei@truedei-code:qt_demo$

      这个问题的关键在与：

      • 1.我认为飞凌的团队在提供原始代码的时候，应该清理掉该项目编译生产的.o,Makefile,qt的stash文件；
      • 2.shell脚本可以优化下：

      现在的：

      cd 4g/ && ( test -e Makefile || /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/qmake -o Makefile /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/forlinx/qt_demo/4g/4g.pro ) && make -f Makefile

      会出现的问题：

      test -e Makefile命令会检测是否存在Makefile,如果存在就不执行后面的语句重新生产了；

      其实去掉test -e Makefile或者把||改成&&（感觉改成&&就起不到什么作用了，和检查不检查没区别）。

      写这个脚本的作者应该是这样想的：

      • 用户初次生产之后，就不让再次生成了，编译时可以节省时间；

      创建自己的项目

      这个牵扯到项目放在哪里，想知道放在哪里合适，就需要熟悉项目的整体架构。

      砍下这个目录：

      可以打开OKT536-linux-sdk/buildroot/package/auto/build.sh研究下：

      看得出来，这各forlinx就是飞凌新增的脚本片段。

      我们可以把OKT536-linux-sdk/buildroot/package/auto目录当项目根目录，继续创建目录

      我完全是把OKT536-linux-sdk/buildroot/package/auto/sdk_demo/usbcam_test拷贝过来了，改了个名字

      build.sh脚本新增：

      
#########truedei#########
echo "build $1 truedei ..."
make -C $LICHEE_BUILDROOT_DIR/package/auto/truedei/ $1
if [ $? -ne 0 ]; then
	echo  "build truedei fail ..."
	exit 1
else
	cp -rf $LICHEE_BUILDROOT_DIR/package/auto/truedei/bin/*	$LICHEE_BR_OUT/target/usr/bin/
fi

      Makefile需要修改下：

      57c7f6dd-e714-42d0-a25d-e16c3c498f28-image.png

      INSTALL_TRUEDEI_PATH变量是在auto目录下的makefile_cfg中定义的：

      
# 自定义自己的项目
INSTALL_TRUEDEI_PATH = $(PACKAGE_PATH)/truedei/bin

      然后就可以编译了，为了省时间，可以直接到项目中编译即可：

      truedei@truedei-code:truedei$ 
truedei@truedei-code:truedei$ pwd
/media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/truedei
truedei@truedei-code:truedei$ 
truedei@truedei-code:truedei$ 
truedei@truedei-code:truedei$ 
truedei@truedei-code:truedei$ make
-e 
/media/truedei/soft/Ok536N-C/OKT536-linux-sdk/out/t536/OKT536-C/buildroot/buildroot/host/bin/aarch64-none-linux-gnu-g++ -g  -o truedei  ./usbcam_test.o  -L/media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/sdk_lib
generate truedei success!!!
 cp -f truedei /media/truedei/soft/Ok536N-C/OKT536-linux-sdk/buildroot/package/auto/truedei/bin 
make finish!!!
