CMake was unable to find a build program corresponding to "Ninja". about libpitaya HOT 8 CLOSED

Did you run brew install ninja? If that does not work, you can modify the Makefile and remove the -GNinja section from the command. It will then use make instead of ninja.

Oops, now that I saw, setup-mac should install ninja. Do you have brew installed? If it does not work just do what I mentioned in the comment above

from libpitaya.

yes, I installed ninja with run " brew install ninja ". now, remove the -GNinja, but still reporting this error。

ardendeiMac:libpitaya arden$ ninja
ninja: error: loading 'build.ninja': No such file or directory

Ok, now the error is related to the toolchain. It says that there is not a file android.toolchain.cmake in that path. This means you have to point the program to the NDK location you have. Suppose you downloaded and installed the NDK r17b at ~. You would then run the following command to build for android:

make ANDROID_TOOLCHAIN_FILE=~/android-ndk-r17b/build/cmake/android.toolchain.cmake build-android

You can also run the target setup-android-mac, it will download the ndk into the folder temp at the current directory. If you do that, then you will have to change the ANDROID_TOOLCHAIN_FILE variable from the previous command to the newly downloaded ndk into the temp folder.

A complete setup to build for android could be someting like the following:

make setup-android-mac
make ANDROID_TOOLCHAIN_FILE=temp/android-ndk-r17b/build/cmake/android.toolchain.cmake build-android

from libpitaya.

Looking at the readme now this is an issue on the makefile, I will update it with the correct instructions for android.

from libpitaya.

make setup-android-mac
make ANDROID_TOOLCHAIN_FILE=temp/android-ndk-r17b/build/cmake/android.toolchain.cmake build-android

it's ok.
