Errors in building for android: <stdio.h> not found and openBlas failed to compile

[Siddhant24]

I get the following errors when trying to run ./tools/build_android.sh
The main error seems to be <stdio.h> not found. I followed the procedure mentioned in README. I have all the dependencies installed.
$NDK_HOME is set correctly:

echo $NDK_HOME 
/home/sid/Android/Sdk/ndk-bundle

@Siddhant24 I guess it's the NDK version problem. NDK version r16 (and later) changed a lot of things. Adding some special arguments or changing it to r15 could solve the problem. I'll re-check this problem and find a way to fix it.

[Siddhant24]

@solrex I also posted this issue on stackoverflow. Some suggestions in the comments.

Using NDK version r15 resolved openBLAS build problem. Now I get the following errors:

[solrex]

@Siddhant24 Do you have "make" installed? Try "which make".

[Siddhant24]

@solrex Yes I have "make" installed.
"which make" returns usr/bin/make

[noob-ja]

@Siddhant24
after hours of checking here and there,
i finally found the solution to the problem,
downgrade/upgrade cmake to 3.7.2
