Question

我能够从源代码中成功地在Ubuntu 14.04上构建cython，如本SE问题/答案Compiling cython From source with icc所述，我从这里下载了源代码 - Cython source code download。

编译cython的命令是

CC = icc LINKCC = icc python3.4 setup.py build

我正在附上构建日志。 STILL 使用gcc进行链接。以下是构建日志的示例。

似乎CC = icc LINKCC = icc NOT 似乎将链接器更改为icc。它仍在使用x86_64-linux-gnu-gcc。当我设置环境变量LDFLAGS = -lirc时，环境变量被传递给gcc而不是icc。此外，当我将打印语句放在BuildExecutable.py中时，它们不会被调用。

icc -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -g -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/python3.4m -c /home/aswin/libPython/Cython-0.24/Cython/Plex/Scanners.c -o build/temp.linux-x86_64-3.4/home/aswin/libPython/Cython-0.24/Cython/Plex/Scanners.o

如何解决？

Answer 1

您需要覆盖链接器

通过设置导出LDSHARED =＆＃34; icc -shared＆＃34;。这会生成icc链接器。以下是键入

的构建日志示例

CC = icc python3.4 setup.py build_ext

或者您也可以通过键入

来执行相同的操作

LDSHARED =＆＃34; icc -shared＆＃34; CC = icc python3.4 setup.py build_ex

icc -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -g -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -fPIC -I/usr/include/python3.4m -c /home/a/libPython/Cython-0.24/Cython/Plex/Scanners.c -o build/temp.linux-x86_64-3.4/home/a/libPython/Cython-0.24/Cython/Plex/Scanners.o

您可以尝试将-static-intel添加到链接选项，以便所有英特尔特定功能都是静态链接的。
