could not get version from cmake.dir

Question

when I build syc my android project it comes like this

How can I solve this error?

Answer 1

You may want to specify the cmake version in your build.gradle file thusly [1]

android {
    ...
    externalNativeBuild {
        cmake {
            ...
            // Specifies the version of CMake the Android plugin should use. You need to
            // include the path to the CMake binary of this version to your PATH
            // environmental variable.
            version "3.10.2.4988404"
        }
    }
}

For versions downloaded by the sdk manager, I didn't need to specify cmake.dir in my local.properties. Try deleting it entirely.

I needed to specify cmake.dir when I used a version of cmake that wasn't installed from Android Studio's sdk manager. Then I had to put the path to the cmake installation directory (the one containing the bin/cmake), not the cmake binary directory directly.

Answer 2

For me, I am using the newest version of CMAKE from the source repo. It by default installs to /usr/local/bin/cmake.

The problem is that the error message never says that it is adding /bin/cmake to the path...

so for the future in your local.properties make like so:

cmake.dir=/usr/local/
