[SOLVED] PNaCl & gtest—pnacl-ld: Incompatible object file (X8664 != X8632)

I'm a newbie at this,Please help me ...T_T...

Recently I was building pthreadpool(required by NNPACK) with ninja on my Ubuntu 14.04 64bit. It requires Google PNaCl(Portable Native Client) and Google Test,and I installed both.

After I run python ./configure.py in pthreadpool root dir, it generated a file build.ninja:

But when I run the command ninja,there came the error:

[4/6] CXXLD[PNaCl] pthreadpool.bc
FAILED: /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.bc 
/toolchain/linux_pnacl/bin/pnacl-clang++ -o /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.bc /home/rokim/NNPACK/third-party/pthreadpool/build/pthreadpool.c.bc /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.cc.bc -lgtest -L/lib/pnacl/Release 
pnacl-ld: Cannot find '-lgtest'
ninja: build stopped: subcommand failed.

I thought it may be the path problem,so I put libgtest.a and libgtest_main.a (Generated from Google Test) in /usr/lib/gtest and modified the build.ninja:

libs = -L/usr/lib/gtest -lgtest_main -lgtest

It seems ninja found the lib files, but there came the error:

[1/3] CXXLD[PNaCl] pthreadpool.bc
FAILED: /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.bc 
/toolchain/linux_pnacl/bin/pnacl-clang++ -o /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.bc /home/rokim/NNPACK/third-party/pthreadpool/build/pthreadpool.c.bc /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.cc.bc -L/usr/lib/gtest -lgtest_main -lgtest -L/lib/pnacl/Release 
pnacl-ld: /usr/lib/gtest/libgtest_main.a: Incompatible object file (X8664 != X8632)
ninja: build stopped: subcommand failed.

I believe the lib files are good since I tried to use g++ to compile a test.cpp:

g++ test.cpp -lgtest_main -lgtest -lpthread

And it worked.

So I thought it might be something wrong about pnacl or the way I use it.I googled the 32bit 64bit incompatible problem about pnacl and gtest but I got nothing. Now I have totally no idea about what to do since I'm a newbie at this...

So please, any help, idea or suggestions would be greatly appriciate!

For Google PNaCl,I downloaded the nacl_sdk.zip and unziped it to /home/rokim/nacl_sdk and I got sdk_tools and pepper_49 up to date.

For Google Test,I run sudo apt-get install libgtest-dev . After cmake and make I got libgtest.a and libgtest_main.a then I put them into /usr/lib and /usr/local/lib.The gtest include file are put into /usr/include and usr/local/include.
