Python distutils gcc 路径
我正在尝试交叉编译 pycrypto 包，而且我越来越接近，但是，我遇到了一个我无法弄清楚的问题。
我希望 distutils 使用交叉编译特定的 gcc，所以我设置了 CC 环境变量，它似乎尊重编译器第一次调用的设置，但仅此而已。
export CC="/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc"
/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc -fno-strict-aliasing -fwrapv -Wall -Wstrict-prototypes -fPIC -std=c99 --sysroot=/opt/teeos/buildroot/output/staging -I/opt/teeos/buildroot/output/staging/usr/include/python2.7 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/python2.7 -c src/_fastmath.c -o build/temp.linux-i686-2.7/src/_fastmath.o
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions build/temp.linux-i686-2.7/src/_fastmath.o -lgmp -o build/lib.linux-i686-2.7/Crypto/PublicKey/_fastmath.so
unable to execute gcc: No such file or directory
我暂时移动了我的系统 gcc，所以找不到它。
如何让 distutils 在每次调用编译器时尊重 CC=/opt/buildroot... 选项/设置我想要 distutils 使用的 GCC / LD 的路径？
I'm trying to cross-compile the pycrypto package, and I'm getting closer and closer however, I've hit an issue I just can't figure out.
I want distutils to use the cross-compile specific gcc- so I set the CC env var and it seems to respect the setting for the first invocation of the compiler, but thats it.
export CC="/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc"
/opt/teeos/buildroot/output/host/usr/bin/i586-linux-gcc -fno-strict-aliasing -fwrapv -Wall -Wstrict-prototypes -fPIC -std=c99 --sysroot=/opt/teeos/buildroot/output/staging -I/opt/teeos/buildroot/output/staging/usr/include/python2.7 -O3 -fomit-frame-pointer -Isrc/ -I/usr/include/python2.7 -c src/_fastmath.c -o build/temp.linux-i686-2.7/src/_fastmath.o
gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions build/temp.linux-i686-2.7/src/_fastmath.o -lgmp -o build/lib.linux-i686-2.7/Crypto/PublicKey/_fastmath.so
unable to execute gcc: No such file or directory
I temporarily moved my systems gcc so it can't be found.
How do I make distutils respect the CC=/opt/buildroot... option for every invocation of the compiler / set the path to the GCC / LD I want distutils to use?

这听起来类似于我最近给出的另一个答案 自定义distutils 编译器。您还需要定义
LDSHARED，这是用于生成最终共享对象的命令。看看这是否有效：然后将
gcc替换为您所需的编译器以及CC和LDSHARED环境变量中的选项：This sounds similar to another answer I recently gave for customizing the distutils compiler. You'll also need to define
LDSHAREDwhich is the command used to produce the final shared object. See if this works:Then replace
gccwith your desired compiler and options in theCCandLDSHAREDenvironment variables:
