If you check out source code from GIT right now, it will not build and I have not found a solution. But if you add the following contents to a file called Makefile in libbthread-master directory, you can build: PLATFORM = $(uname -o) ifneq ($(PLATFORM),Android) all: # mv pt-test.c pt-test # cat `ls *.c` > just-pt.c g++ -c -o jpt.o just-pt.cc -I. ar crs jpt.a jpt.o clean: rm -f *.a *.o install: else all: install: clean: endif
