我正在安装libwebsocket，它给我错误：---

目前，当我运行libtool --version：---
/home/pi$ libtool --version

如果我运行whereis命令，则会得到以下输出：----
/pi/libtool-2.4.2$ whereis libtool
libtool:
我必须安装libtool 2.4.2版才能摆脱上述错误。
现在我已经为libtool安装了2.4.2版本：-
ftp://ftp.gnu.org/gnu/libtool/libtool-2.4.2.tar.gz
安装2.4.2版本的libtool后，如果运行whereis命令，则会得到以下输出：
/pi/libtool-2.4.2$ whereis libtool
libtool: /usr/local/bin/libtool
但是如果我运行libtool --version：---
/home/pi$ libtool --version
ltmain.sh (GNU libtool) 1.5.26 (1.1220.2.492 2008/01/30 06:40:56)
为什么libtool --version命令没有显示libtool 2.4.2的最新安装版本？
当我运行./autogen.sh时，我也遇到libwebsocket的错误。
最佳答案
您是否使用CMake尝试了最新版本（1.22）？直接构建。
$ git clone git://git.libwebsockets.org/libwebsockets
$ cd libwebsockets/
阅读README.build。不知道libwebsockets的旧版本，但是我猜它是
现在更多的是使用CMake而不是自动工具。
$ mkdir build && cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX:PATH=/usr/local
最后一行类似于：
$ ./configure --prefix=/usr/local
整个过程很快完成，没有任何问题。
