Toolchain command do not take effect in CMake build after menuconfig settings
Here is an example:
Our current Toolchain File overwrite the ARCHIVE command
https://github.com/apache/nuttx/blob/992719730f355ed3132c3204153f919822870074/arch/arm/src/cmake/Toolchain.cmake#L92-L94
but <CMAKE_AR>
makes different choices depending on whether LTO
is enabled or not.
https://github.com/apache/nuttx/blob/992719730f355ed3132c3204153f919822870074/arch/arm/src/cmake/Toolchain.cmake#L75-L86
If every Toolchain configs is configured in defconfig, everything will work normally.
But if LTO
is not enabled in defconfig and I call cmake --build -t menuconfig
to open LTO
, then the expectation is different from the setting.
Because the execution of CMake is divided into three stages: configure, generate and build. the Toolchain command (such as CMAKE_AR above) is configured in stages configure, generate and is solidified in the generated build file (such as Makefile). so in the end this menuconfig modification will NOT take effect.
How can we improve this to make it work properly?
@pkarashchenko any idea?
In this case, we should regenerate Makefile?
