ndk-build is stupid and tries to compile any .cpp file in src

[Ghabry]

Maybe ndk-build should depend on a list like all other sane build systems and stop compiling my non-clean upd conflict files player.BASE.cpp because they end on .cpp -.-

[fdelapena]

As a detail, the problem is at builds/android/jni/src/Android.mk which uses wildcards.
A possible solution without needing to maintain yet another makefile file list might be by using Androgenizer, which generates .mk files from autotools. CMake might help too. Or just a plain maintenance shell script to do the trick.

[fdelapena]

Is this one fixed with the updated build?

[Ghabry]

Nope

[fmatthew5876]

Does this bug still exist in 2019?

[carstene1ns]

Yes, and this also affects most dedicated ports with Makefiles. Will vanish when this has been adapted to cmake.

[Ghabry]

ndk-build is very likely the last one which is going to be adopted to CMake because nobody wants to understand how the interaction between gradle and CMake works.
