在 CentOS 上安装 M2Crypto

Question

我正在尝试通过从源代码编译来在 CentOS 上安装 M2Crypto。 我正在做一个 python setup.py 构建 但我收到以下错误，

/usr/local/lib/python2.6/distutils/dist.py:266: UserWarning: Unknown distribution option: 'test_suite'
  warnings.warn(msg)

SWIG/_evp.i:9: Error: Unable to find 'openssl/opensslconf.h'
SWIG/_ec.i:7: Error: Unable to find 'openssl/opensslconf.h'
error: command 'swig' failed with exit status 1

请指教......

Answer 1

以下内容应该有效：

env SWIG_FEATURES="-cpperraswarn -includeall -D__`uname -m`__ -I/usr/include/openssl" python setup.py build

编辑：当然还需要 openssl-devel 包。

Answer 2

我刚刚遇到这个问题。在 M2Crypto 的安装文件中：

Note about Fedora Core -based Distributions
----------------------------------------------------

Fedora Core (and RedHat, CentOS etc.) have made changes to OpenSSL
configuration compared to many other Linux distributions. If you can not
build M2Crypto normally, try the fedora_setup.sh script included with
M2Crypto sources.

我的解决方案是获取源 来自 PyPI 或来自来源。然后在 M2Crypto 目录中：

$ chmod +x fedora_setup.py
$ ./fedora_setup.py install

如果您使用的是 virtualenv，请更改该文件中 python 解释器的路径，或者在构建之前激活您的环境。

我的系统上唯一不满足的依赖项是openssl-devel。

Answer 3

安装openssl-devel。

Answer 4

按照 Brian 的说明进行操作，并确保您已安装 openssl-devel。如果您遇到这样的错误：

./fedora_setup.sh build
running build
running build_py
running build_ext
building 'M2Crypto.__m2crypto' extension
swigging SWIG/_m2crypto.i to SWIG/_m2crypto_wrap.c
swig -python -I/usr/include/python2.6 -I/usr/include -includeall -o SWIG/_m2crypto_wrap.c SWIG/_m2crypto.i
SWIG/_evp.i:12: Error: Unable to find 'openssl/opensslconf-i686.h'
SWIG/_ec.i:7: Error: Unable to find 'openssl/opensslconf-i686.h'
error: command 'swig' failed with exit status 1

您正在 64 位硬件上运行 i386 操作系统。 arch =´uname -m´ 将生成 i686。解决这个问题最简单的方法是创建一个符号链接。

sudo ln -s /usr/include/openssl/opensslconf-i386.h /usr/include/openssl/opensslconf-i686.h

或者，如果您遇到以下错误：

./fedora_setup.sh build
running build
running build_py
running build_ext
SWIG/_m2crypto_wrap.c:27555: error: ‘Swig_var__evp_err_set’ undeclared (first use in this function)
SWIG/_m2crypto_wrap.c:27564: error: ‘Swig_var__dh_err_get’ undeclared (first use in this function)
SWIG/_m2crypto_wrap.c:27564: error: ‘Swig_var__dh_err_set’ undeclared (first use in this function)
SWIG/_m2crypto_wrap.c:27576: error: ‘Swig_var__rsa_err_get’ undeclared (first use in this function)
...

某些标头丢失，只需发出以下命令并重试：

sudo yum install python-devel

Answer 5

我现在（2018年）遇到了这个问题，我通过安装 openssl-devel、gcc 和 make

yum install gcc gcc 解决了它-c++ make openssl-devel

Answer 6

这适用于 RHEL 8.7，也可能适用于 CentOS 8

pip install swig wheel M2Crypto
yum -y install gcc gcc-c++ make openssl-devel python3-devel
