1.软件包对 RT-Thread 版本的判断使用如下方法: 在进行 RT-Thread 版本限制的时候,要注意此软件包或软件包版本是否真的在此 RT-Thread 版本不可用,还是由于 bsp 的问题 RT_VER_NUM 这个宏是在Kconfig中定义并在rtconfig.h中自动生成的 在.c/.h文件下采用如下方法(不要使用<rtthread.h>里定义的版本宏来判断)
#if RT_VER_NUM >= 0x50000 。。。 #else 。。。 #endif /*RT_VER_NUM >= 0x50000*/

2.针对Kconfig文件下,需要注意choice选择块内,不可再包含if块,否则在Kconfig-C版本前端中无法正确识别(python前端可以正确识别),如下为错误示范:
choice prompt "version" help Select the pahomqtt version if RT_VER_NUM >= 0x40100 config PKG_USING_PAHOMQTT_LATEST bool "latest" endif if RT_VER_NUM < 0x40100 config PKG_USING_PAHOMQTT_V110 bool "v1.1.0" endif endchoice
以下为正确示范,采用depends on关键字指定版本依赖,可选,如果使用全部RT-Thread版本则不需要加depends on:
choice prompt "version" help Select the pahomqtt version config PKG_USING_PAHOMQTT_LATEST bool "latest" depends on RT_VER_NUM >= 0x40100 config PKG_USING_PAHOMQTT_V110 bool "v1.1.0" depends on RT_VER_NUM < 0x40100 endchoice
默认版本可以不用特意用default关键字指定,按照版本从高到低排序即可,choice语法块会自动选择满足要求的最高版本。
Sorry, something went wrong.
