尝试在 CentOS 6.x 上安装 tmux 失败并显示错误：'EVBUFFER_EOL_LF' undeclared

Question

我尝试使用以下步骤编译 tmux：

yum -y install ncurses-devel libevent-devel
wget http://downloads.sourceforge.net/tmux/tmux-1.9a.tar.gz
tar -xvzf tmux-1.9a.tar.gz
cd tmux-1.9a
./configure
make

该make命令失败，出现以下错误：

control.c:64:47: error: ‘EVBUFFER_EOL_LF’ undeclared (first use in this function)

以下是安装的 ncurses-devel 和 libevent-devel 软件包的详细信息。

在 CentOS 6.x 上安装 tmux 的正确方法是什么？

Answer 1

出现此问题是因为 yum 安装了 libevent 1.4 版，而 tmux 1.9 需要 libevent 2.0 版。解决方案是从源安装 libevent 2.0 版。

这是从头开始安装 tmux 的完整命令集。

yum -y install ncurses-devel

wget https://github.com/libevent/libevent/releases/download/release-2.0.22-stable/libevent-2.0.22-stable.tar.gz
tar -xvzf libevent-2.0.22-stable.tar.gz
cd libevent-2.0.22-stable
./configure
make -j 4
make install
cd ..

wget https://github.com/tmux/tmux/releases/download/2.1/tmux-2.1.tar.gz
tar -xvzf tmux-2.1.tar.gz
cd tmux-2.1
./configure LDFLAGS="-Wl,-rpath,/usr/local/lib"
make -j 4
make install

这里有三个命令块。

1. yum 命令安装编译 tmux 所需的 ncurses-devel 包（如果它还没有）。
2. 然后我们从源代码编译 libevent 2.0 版并安装它。
3. 然后我们从源代码编译 tmux 2.1 版并安装它。这样做时，我们确保将 tmux 链接到我们安装在 /usr/local/lib 中的 libevent，否则会出现此错误：tmux: error while loading shared libraries: libevent-2.0.so.5: cannot open shared object file: No such file or directory。

最后，执行tmux命令启动 tmux。

Answer 2

安装libevent-devel 的libevent 2 -devel 即时

在我的 64 位机器上：

yum install libevent2-devel.x86_64

如果您已经安装了 libevent-devel，请先卸载它。
