I try to build my program without jni ndk-build , but by a standalne arm-kind cross compliers way .
However ,after I write a simple sample , using STL and thread function with my own Makefile , and I do make command,
I encount all kind of weird program .
- error 0: in a dynamic library way
[dengwei@localhost ~]$ make
arm-marvell-linux-gnueabi-g++ hi.cpp -o hi1234 -lpthread
[dengwei@localhost platform-tools]$ adb push ~/hi1234 /data/
[dengwei@localhost platform-tools]$ adb shell
# /data/hi1234
/data/hi1234: not found
analyse: libpthread.so may not found.
- error 1: in a static library way
arm-marvell-linux-gnueabi-g++ -static hi.cpp -o hi1234 -lpthread
# /data/hi1234
terminate called after throwing an instance of '__gnu_cxx::__concurrence_broadcast_error' what(): __gnu_cxx::__concurrence_broadcast_error
[1] Aborted /data/hi1234
analyse: libpthread.a doesn't may real match and other unknow reason
some say add "-Wl,--whole-archive -lpthread -Wl,--no-whole-archive -lc " in complie command will fix the problem ,but it does NOT work for me.
I change cross compliers to use standalone cross compliers : ref to $(NDK)/docs/STANDALONE-TOOLCHAIN.html
==============thread succeed this time===============================
$make
arm-linux-androideabi-g++ hi.o -static -L /home/dengwei/standalone-toolchain/sysroot/usr/lib/libthread_db.a -L /home/dengwei/standalone-toolchain/arm-linux-androideabi/lib/libsupc++.a -lstdc++ -DTHREAD -o hi1234
---------------result:------------------------------
# ./hi1234
hello world
thread begin
thread end

But STL still can NOT work. I found solution here in stackoverflow
"I think "APP_STL:=stlport_static" must be in Application.mk file. Create a "Application.mk" file and write "APP_STL:=stlport_static" in it."
#include <cstddef>
#include <iostream>
using namespace std;
int main(void)
{
string sss;
const char *hs= "this is a string";
sss.assign(hs, strlen(hs));
printf("%s\n", sss.c_str());
return 0;
}
[dengwei@localhost jni]$ ndk-build
Compile++ thumb : test-libstl <= test-libstl.cpp
Executable : test-libstl
Install : test-libstl => libs/armeabi/test-libstl
I begin to find I did NOT fully unstand configure and Makefile
Here comes the solution:
LDFLAGS= -static
LIBS+= -L /home/dengwei/standalone-toolchain/sysroot/usr/lib/libthread_db.a
LIBS+= -L /home/dengwei/standalone-toolchain/arm-linux-androideabi/lib/libsupc++.a
INCLUDES= -I $(STANDALONE_PATH)/arm-linux-androideabi/include/c++/4.6/
INCLUDES+= -I $(STANDALONE_PATH)/arm-linux-androideabi/include/c++/4.6/arm-linux-androideabi
CXXFLAGS= -DTHREAD
CXXFLAGS+= -DUSE_STL
CXXFLAGS+= $(INCLUDES)
#CXXFLAGS+= -Wl,--whole-archive -lpthread -Wl,--no-whole-archive -lc
OBJS=hi.o
PROGRAM=hi1234
$(PROGRAM):$(OBJS)
$(CXX) $(OBJS) $(LDFLAGS) $(LIBS) $(CXXFLAGS) -o $@
clean:
rm $(OBJS) -rf
rm $(PROGRAM) -rf
INCLUDES+= -I $(STANDALONE_PATH)/arm-linux-androideabi/include/c++/4.6/arm-linux-androideabi
LIBS+= -L /home/dengwei/standalone-toolchain/sysroot/usr/lib/libthread_db.a
LIBS+= -L /home/dengwei/standalone-toolchain/arm-linux-androideabi/lib/libsupc++.a
above are using for static complie
==============stl succeed this time===============================

OK, I'm done here.
So , I need to write articles about configure and Makefile.
