M2Crypto未安装在venv中,或者swig未定义__x86_64__,这破坏了针对OpenSSL的编译

linux

我正在尝试将Python M2Crypto软件包安装到x86_64 RHEL
6.1计算机上的virtualenv中。此过程将调用swig,该失败将失败,并显示以下错误:

$ virtualenv -q --no-site-packages venv
$ pip install -E venv M2Crypto==0.20.2

我已经通过RedHat的RPM软件包安装了OpenSSL 1.0.0。

/usr/include/openssl/opensslconf.h导致错误的部分如下所示:

#if defined(__i386__)
#include "opensslconf-i386.h"
#elif defined(__ia64__)
#include "opensslconf-ia64.h"
#elif defined(__powerpc64__)
#include "opensslconf-ppc64.h"
#elif defined(__powerpc__)
#include "opensslconf-ppc.h"
#elif defined(__s390x__)
#include "opensslconf-s390x.h"
#elif defined(__s390__)
#include "opensslconf-s390.h"
#elif defined(__sparc__) && defined(__arch64__)
#include "opensslconf-sparc64.h"
#elif defined(__sparc__)
#include "opensslconf-sparc.h"
#elif defined(__x86_64__)
#include "opensslconf-x86_64.h"
#else
#error "This openssl-devel package does not work your architecture?"
#endif

gcc定义了正确的变量:

$ echo | gcc -E -dM - | grep x86_64
#define __x86_64 1
#define __x86_64__ 1

但是明显的喝醉没有,因为这是失败的那行:

swig -python -I/usr/include/python2.6 -I/usr/include -includeall -o \
  SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i

有没有办法通过更改系统配置来解决此问题?M2Crypto被安装在virtualenv中,这是我无法控制的较大脚本的一部分,因此,避免与M2Crypto文件混在一起是一件好事。

M2Crypto提供了fedora_setup.sh脚本来处理Fedora / RL / CentOs版本的问题,但是pip当然对此一无所知。

pip安装失败后,它将下载的内容保留在venv / build / M2Crypto目录中。做这个:

cd <path-to-your-venv>/venv/build/M2Crypto
chmod u+x fedora_setup.sh
./fedora_setup.sh build
./fedora_setup.sh install

这在我的安装过程中起作用
