linux - (QNAP NAS)Linux - 安装 pycurl (找不到 libcurl.a)

Question

我正在尝试在我的 NAS(QNAP TS-459) 上安装 Pycurl，但出现错误“libcurl.a:没有这样的文件或目录”。以下是来自控制台的日志:

知道如何解决问题吗？谢谢!

Answer 1

今天我在 Synology NAS 上遇到了同样的问题。问题是 curl-config --libs 和 curl-config --static-libs 都返回一些输出。因此，pycurl 会尝试为静态库和共享库进行编译。但是 libcurl 包没有静态库。所以，我通过以下方式解决了这个问题:

如果 curl-config --built-shared 返回 yes，请不要运行 curl-config --static-libs。

这是补丁:

     for e in libs:
         if e[:2] == "-l":
             libraries.append(e[2:])

适用于 v7.19.0。或者只从 here 获取最新版本的 setup.py
