c++ - nvcc/cuda 3.1 - ghtr-default.h 泛滥 "declared static"但未定义警告

Question

使用 nvcc(使用 cuda 3.1)编译项目时，我从 gthr-default.h 收到大量警告:

/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/x86_64-redhat-linux/bits/gthr-default.h:118: warning: ‘int __gthrw_pthread_once(pthread_once_t*, void (*)())’ declared ‘static’ but never defined
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/x86_64-redhat-linux/bits/gthr-default.h:119: warning: ‘void* __gthrw_pthread_getspecific(pthread_key_t) throw ()’ declared ‘static’ but never defined
/usr/lib/gcc/x86_64-redhat-linux/4.4.4/../../../../include/c++/4.4.4/x86_64-redhat-linux/bits/gthr-default.h:120: warning: ‘int __gthrw_pthread_setspecific(pthread_key_t, const void*) throw ()’ declared ‘static’ but never defined

我四处寻找，似乎无法找到抑制这种噪音的方法，除了删除 -Wall，我真的不想这样做。这对任何人来说都很熟悉吗？

我的 CXXFLAGS 是:

CXXFLAGS=-Isrc -I../cxxtest -I$(CUDA_INCLUDE_DIR) -Xcompiler -O2 -Xcompiler -Wall

我也尝试将 $(CUDA_INCLUDE_DIR) 添加到 -Xcompiler 选项，但无济于事。我不想从设置中删除 Wall...还有其他选项吗？

尝试将你的 pthreads 代码分离到不同的文件中，这样你就可以避免#including 任何文件触发这些警告...
