专家,

我尝试在虚拟的Python环境中使用pip安装numba。我遇到以下错误:

但是 omp.h 存在于 /usr/local/llvm70/lib/clang/7.0.1/include/omp.h .

非常感谢您为解决此问题提供的任何帮助。我在跑步 FreeBSD 12 和 python3.6 . 我有软链接 llvm7 作为默认值,作为一个信息,这将是有帮助的。

我想makefile在找 欧姆 与实际位置不同的位置。如果是这样,在 pip 安装?

随访: 设置 CPPFLAGS 正如@hoefring所建议的,确实解决了上述问题。但是,下一个错误如下:

我有两个 alloca.h 在以下位置:

/usr/src/contrib/ofed/libibverbs/alloca.h
/usr/src/cddl/compat/opensolaris/include/alloca.h

我不知道应该包括哪一个。

谢谢你的努力。

Linux

omp.h 通常是 gcc 编译器,例如安装在Ubuntu上的

$ sudo apt install libgcc-7-dev

FreeBSD

标题由提供 devel/openmp . 安装时可以使用:

$ sudo pkg install devel/openmp

这个地方 欧姆 进入之内 /usr/local/include ,默认情况下包括dirs。

自定义包括

如果要在自定义include目录下附加头,请使用 CPPFLAGS / CFLAGS 环境变量:

$ CPPFLAGS="-I/usr/local/llvm70/lib/clang/7.0.1/include/" pip install numba

我想是第二个错误吧 numba 写的时候并没有考虑到freebsd(也不确定cuda和freebsd的总体表现是否不错)。也许吧 open an issue ?我想补丁的建议是 numba/npyufunc/workqueue.c 应该是

 #include <pthread.h>
 #include <unistd.h>
+#if !defined (__FreeBSD__)
 #include <alloca.h>
+#endif
 #define NUMBA_PTHREAD
 #endif

除此之外,试着包括第二个( /usr/src/cddl/compat/opensolaris/include/alloca.h )
