Hi, i want to know how to auto run CMakeGenerate before CMakeBuild, I try to set:

augroup vim-cmake-group
    autocmd User CMakeBuildPre CMakeGenerate
augroup END

but it failed. image

Hi, thanks for asking this.

Autocommands should be used to run synchronous command, i.e. command that block the execution until they complete. :CMakeGenerate is an asynchronous command, it starts a job in the background and it does not block execution.

At the moment, if there's a (asynchronous) :CMake command running, attempting to run another :CMake command will throw the error you're seeing. I could implement something to fix this, e.g. pipeline commands and run them when nothing else is running, but I'd have to think whether this is a good idea.

Anyway, is there a good reason why you want to run :CMakeGenerate before :CMakeBuild? In general it should not be necessary, see for instance When should I rerun cmake? - Stack Overflow

I am a beginner of cmake, the information you provided is very useful. As you said it is not necessary. Thanks for your reply.
