Question

我是新手，请帮助我...... T_T ......

最近我在我的Ubuntu 14.04 64位上使用 ninja 构建了 pthreadpool （ NNPACK 所需）。它需要 Google PNaCl(Portable Native Client) 和 Google测试，我安装了两者。

在pthreadpool root dir中运行 python ./configure.py 后，它生成了一个文件 build.ninja ：

但是当我运行命令 ninja 时，出现错误：

＆＃13;

[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.

＆＃13;

我认为这可能是路径问题，所以我将 libgtest.a 和 libgtest_main.a （由Google Test生成）放在/ usr / lib / gtest中修改了 build.ninja ：

＆＃13;

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

＆＃13;

似乎ninja找到了lib文件，但出现了错误：

＆＃13;

[1/3] CXXLD[PNaCl] pthreadpool.bc
FAILED: /home/rokim/NNPACK/third-party/pthreadpool/build/test/pthreadpool.bc

pnacl-ld: /usr/lib/gtest/libgtest_main.a: Incompatible object file (X8664 != X8632)
ninja: build stopped: subcommand failed.

＆＃13;

我相信lib文件很好，因为我尝试使用g ++编译test.cpp：

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

它有效。

所以我认为pnacl或我使用它的方式可能有些不对。我用谷歌搜索了关于pnacl和gtest的32位64位不兼容问题，但我什么也没得到。现在我完全不知道该做什么，因为我是这个新手...

所以请，任何帮助，想法或建议都会非常适合！

对于Google PNaCl，我下载了nacl_sdk.zip并将其解压缩到/ home / rokim / nacl_sdk，我得到了 sdk_tools 和 pepper_49 最新版。

对于Google Test，我运行 sudo apt-get install libgtest-dev 。在 cmake 和 make 之后，我得到 libgtest.a 和 libgtest_main.a ，然后我将它们放入/ usr / lib和/usr/local/lib.gtest包含文件放入/ usr / include和usr / local / include。

您不能在主机系统中使用带有NaCl编译器的libgtest。您链接的所有内容都必须使用相同的（NaCl）编译器构建。所以你想用pnacl-clang构建libgtest，并将它与你的其他PNaCl构建链接起来。

PNaCl＆amp; gtest-pnacl-ld：不兼容的目标文件（X8664！= X8632）
