在MiniGUI官網提供了編譯方法：http://www.minigui.com/blog/quick-start
編譯5.0和4.0的方法類似，這兩個版本的下載鏈接分別是https://github.com/VincentWei/build-minigui-5.0和https://github.com/VincentWei/build-minigui-4.0，下面以編譯4.0為例。
交叉編譯工具鏈：arm-linux-gnueabihf-gcc 7.3
下載：
$ git clone https://github.com/VincentWei/build-minigui-4.0.git $ cd build-minigui-4.0
執行 ./fetch-all.sh，下載軟件包
編譯兩個會用到的工具bin2c和upf2c：
$ cd mg-tools/tools $ gcc bin2c.c -o bin2c $ sudo cp bin2c /usr/local/bin $ cd mg-tools/font-tools $ gcc upf2c.c -o upf2c $ sudo cp upf2c /usr/local/bin
然后進入cross-build/arm-r16-linux/，這里提供了一個交叉編譯MiniGUI的參考，不過編譯的是時候會有一些問題。
- 修改modify-this-config.sh:
diff --git a/cross-build/arm-r16-linux/modify-this-config.sh b/cross-build/arm-r16-linux/modify-this-config.sh index 698bc6f..c5e0a08 100644 --- a/cross-build/arm-r16-linux/modify-this-config.sh +++ b/cross-build/arm-r16-linux/modify-this-config.sh @@ -3,7 +3,7 @@ # You must set TINA_DIR for r16 tina dirctory. # It is the ONLY line you have to modify in the whole compiling process. -TINA_DIR=/home/projects/r16/tinav2.5 +TINA_DIR=${PWD}/build
- 下載軟件包，./fetch-all.sh
- 修改libinput.txt，替換交叉編譯工具鏈
- 修改build-all.sh，替換交叉編譯工具鏈
下面開始編譯：
- 在交叉編譯libharfbuzz的時候遇到一些問題，然后我用qemu static +ubuntu arm文件系統的辦法直接編譯一個arm版本的harfbuzz庫，編譯時的configure參數使用build-all.sh中的。編譯完成后，將得到的庫和頭文件拷貝到rootfs/usr/local下。
然后為rootfs/usr/local/lib/libharfbuzzex.so.0.20501.0建立一個軟連接，因為在編譯minigui時會檢測libharfbuzz.so
ln -sf libharfbuzzex.so.0.20501.0 libharfbuzz.so
- udev編譯錯誤：
3rd-party/udev-182/src/sd-daemon.c:394: undefined reference to `mq_getattr'
修改build-all.sh，編譯udev時為LDFLAGS增加參數"-lrt"
- minigui編譯錯誤
freetype2.h:65:10: fatal error: ft2build.h: No such file or directory #include <ft2build.h>
修改build-all.sh，編譯minigui時增加-I$WORK_DIR/rootfs/usr/local/include/freetype2
harzbuff-minigui-funcs.c:66:10: fatal error: hb.h: No such file or directory #include <hb.h>
修改build-all.sh，編譯minigui時增加-I$WORK_DIR/rootfs/usr/local/include/harfbuzz
- libmgncs4touch編譯錯誤
grep: /usr/lib/arm-linux-gnueabihf/libfreetype.la: No such file or directory sed: can't read /usr/lib/arm-linux-gnueabihf/libfreetype.la: No such file or directory
刪除rm rootfs/usr/local/lib/libharfbuzzex.la
- mg-tests編譯錯誤
/lib/libminigui_ths.so: undefined reference to `dlsym' /lib/libminigui_ths.so: undefined reference to `dlerror' /lib/libminigui_ths.so: undefined reference to `dlopen' /lib/libminigui_ths.so: undefined reference to `dlclose'
重新編譯minigui，增加編譯參數"-ldl"，然后make clean，重新執行build-all.sh
上面默認編譯的MiniGUI是線程模式，下面編譯process模式，修改build-all.sh，修改minigui的編譯參數“--with-runmode=procs”，然后將“-lminigui_ths”改為“-lminigui_procs”。編譯：
- minigui編譯錯誤
drmvideo.c:2054:18: error: format '%lu' expects argument of type 'long unsigned int', but argument 6 has type 'size_t {aka unsigned int}' [-Werror=format=]
修改minigui的編譯參數，增加：-Wno-error=format=
下面是交叉編譯minigui的壓縮包的下載鏈接：
鏈接: https://pan.baidu.com/s/1JjN3QEr0njw-UWmXdeHF6Q 提取碼: 215s
將procs模式的minigui拷貝到跟文件系統中，然后再把編譯好的mg-samples目錄拷貝到板子上。
修改/usr/local/etc.MiniGUI.cfg:
[system] # GAL engine and default options # The equivalent environment variable: MG_GAL_ENGINE gal_engine=fbcon # The equivalent environment variable: MG_DEFAULTMODE defaultmode=800x600-16bpp # IAL engine # The equivalent environment variable: MG_IAL_ENGINE ial_engine=console mdev=/dev/input/mice mtype=IMPS2
kernel配置上需要配置：
Device Drivers ---> Input device support ---><*> Mouse interface
在運行測試程序時會遇到如下問題：
[root@vexpress-a9 mginit]# ./mginit KERNEL>LoadSharedResource: No such file or directory KERNEL>InitGUI (step 9): Can not load shared resource! Aborted
原因是mginit在運行時，在kernel_LoadSharedResource中其中會創建一個lock文件：/var/tmp/mginit，但是在目前的板子上不存在/var/tmp目錄，所以需要手動在板子上創建一個目錄。
[root@vexpress-a9 mginit]# mkdir /var/tmp
然后重新運行：
root@vexpress-a9 mg-samples]# cd mginit/ [root@vexpress-a9 mginit]# ./mginit IAL: use 'tty' native keyboard engine, with the device file '' IAL Native Engine: keyboard device has been connected. IAL Native Engine: mouse device has been connected. libpng warning: iCCP: known incorrect sRGB profile new child, pid: 870. New comming in client: do_client_join_layer: SERVER: Join a client (graphics) to layer mginit New client joined layer: (mginit, graphics)
運行截圖：
完。
