[New-bugs-announce] [issue36145] android arm cross compilation fails, h

[muhzi]

New submission from muhzi <air.oamyst517 at yahoo.com>:

This is a follow up of #36141, I'm trying to build python for android armv7a.
The problem was the configure script fails to find pthread_create in the android headers. Now after getting past the configuration, I get a build error:

armv7a-linux-androideabi16-clang -c -mfloat-abi=softfp -mfpu=vfpv3-d16 -Wno-unused-result -Wsign-compare -Wunreachable-code -DNDEBUG -g -fwrapv -O3 -Wall    -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Wstrict-prototypes -Werror=implicit-function-declaration   -I. -I./Include    -DPy_BUILD_CORE -o Python/pytime.o Python/pytime.c

        ^

    if (pytime_fromtimespec(tp, &ts, raise) < 0) {
        ^

The declaration for pytime_fromtimespec needs the token HAVE_CLOCK_GETTIME to be defined to 1, which isn't the case (as per pyconfig.h). I checked the android headers and time.h seems to have the necessary function for this token. 

I uploaded pyconfig.h for reference (attached).
