I am facing a problem while trying to compile Python for android armv7a using the latest NDK version (clang). The configure script fails to find pthread library, which should be bundled in libc. Here is the full configure output: Building for armv7a-linux-androideabi configure: loading site script ./config.site checking build system type... x86_64-pc-linux-gnu checking host system type... armv7a-unknown-linux-androideabi checking for python3.7... python3.7 checking for python interpreter for cross build... python3.7 checking for --enable-universalsdk... no checking for --with-universal-archs... no checking MACHDEP... checking for --without-gcc... no checking for --with-icc... no checking for armv7a-linux-androideabi-gcc... armv7a-linux-androideabi16-clang checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... yes checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether armv7a-linux-androideabi16-clang accepts -g... yes checking for armv7a-linux-androideabi16-clang option to accept ISO C89... none needed checking how to run the C preprocessor... armv7a-linux-androideabi16-clang -E checking for grep that handles long lines and -e... /bin/grep checking for a sed that does not truncate output... /bin/sed checking for --with-cxx-main=<compiler>... no checking for the platform triplet based on compiler characteristics... none checking for -Wl,--no-as-needed... yes checking for egrep... /bin/grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking minix/config.h usability... no checking minix/config.h presence... no checking for minix/config.h... no checking whether it is safe to define __EXTENSIONS__... yes checking for the Android API level... 16 checking for the Android arm ABI... 7 checking for --with-suffix... checking for case-insensitive build directory... no checking LIBRARY... libpython$(VERSION)$(ABIFLAGS).a checking LINKCC... $(PURIFY) $(MAINCC) checking for GNU ld... yes checking for --enable-shared... yes checking for --enable-profiling... no checking LDLIBRARY... libpython$(LDVERSION).so checking for armv7a-linux-androideabi-ar... arm-linux-androideabi-ar checking for armv7a-linux-androideabi-readelf... arm-linux-androideabi-readelf checking for a BSD-compatible install... /usr/bin/install -c checking for a thread-safe mkdir -p... /bin/mkdir -p checking for --with-pydebug... no checking for --with-assertions... no checking for --enable-optimizations... no checking for --with-lto... no checking for -llvm-profdata... no checking for -Wextra... yes checking whether armv7a-linux-androideabi16-clang accepts and needs -fno-strict-aliasing... no checking if we can turn off armv7a-linux-androideabi16-clang unused result warning... yes checking if we can turn off armv7a-linux-androideabi16-clang unused parameter warning... yes checking if we can turn off armv7a-linux-androideabi16-clang missing field initializers warning... yes checking if we can turn off armv7a-linux-androideabi16-clang invalid function cast warning... no checking if we can turn on armv7a-linux-androideabi16-clang mixed sign comparison warning... yes checking if we can turn on armv7a-linux-androideabi16-clang unreachable code warning... yes checking if we can turn on armv7a-linux-androideabi16-clang strict-prototypes warning... yes checking if we can make implicit function declaration an error in armv7a-linux-androideabi16-clang... yes checking whether pthreads are available without options... no checking whether armv7a-linux-androideabi16-clang accepts -Kpthread... no checking whether armv7a-linux-androideabi16-clang accepts -Kthread... no checking whether armv7a-linux-androideabi16-clang accepts -pthread... no checking whether armv7a-linux-androideabi16-clang++ also accepts flags for thread support... no checking for ANSI C header files...
