无法在cygwin上安装pycurl：缺少openssl符号CRYPTO_num_locks等

Question

我试图在Windows 7 Cygwin上安装pycurl。我已经使用easy_install在该环境中运行，但命令

easy_install pycurl

给出一堆未定义的符号错误：

/tmp/easy_install-A69Atd/pycurl-7.19.3.1/src/pycurl.c:688: undefined reference to `CRYPTO_set_id_callback'

任何想法解决类似的问题？

的setup.py中缺少库-lcrypto，

class ExtensionConfiguration(object): 
    def __init__(self): 
     self.include_dirs = [] 
     self.define_macros = [("PYCURL_VERSION", '"%s"' % VERSION)] 
     self.library_dirs = [] 
     self.libraries = [] 

改变self.libraries包括crypto：

self.libraries = ["crypto"]
