RT-Thread Stuido 添加LVGL后编辑报错？
发布于 2022-05-13 13:04:16 浏览：75
STM32F49BIT6使用RT Thread Studio 2.2.3 版本4.1.0系统，添加sdram和LTDC驱动后，RGB屏幕正常启动，添加LVGL库和对应的5个接口文件，debug后报下面错误：
make -j8 all
linking...
arm-none-eabi-gcc: error: CreateProcess: No such file or directory
make: *** [makefile:179: rtthread.elf] Error 1
"make -j8 all" terminated with exit code 2. Build might be incomplete.后在“项目”->"解除命令行长度限制"，包下面错误：
make -j8 all
process_begin: CreateProcess(NULL, project_linker.exe link.temp arm-none-eabi-gcc, ...) failed.
make (e=2): 系统找不到指定的文件。
make: *** [makefile:179: rtthread.elf] Error 2
"make -j8 all" terminated with exit code 2. Build might be incomplete.
怎么解决？

应该是这个的问题，但是现在又报其它的错误

如果使用little2RTT软件包，则一切正常
