gnuplot中的pdfcairo'未知或不明确的终端类型'

Question

将gnuplot从4.6升级到5.0.1后，遇到如下错误：

set terminal pdfcairo size 3.0in,2.25in font ',8'
             ^
"plot.plt", line 114: unknown or ambiguous terminal type; type just 'set terminal' for a list

我该如何解决？

PS：pdfcairo 在之前的版本 (4.6) 中运行良好。

我通过以下命令安装 gnuplot：

#build it:
./configure --with-cairo 
make

#install it:
sudo make install

如GNUPLOT Version 5.0.1 Release Notes 中所述，默认情况下包含pdfcairo。

Cairo/pango/wxWidgets 这组终端包括

pngcairo、pdfcairo、epscairo 和 cairolatex 用于输出到文件

wxt 用于交互式显示所有这些都将默认构建，如果 配置脚本找到所需的 libcairo、libpango、libcairo、 libwxgtk 和相关支持库 要禁用这些终端：

./configure --without-cairo ./configure --with-cairo --disable-wxt

Answer 1

我用@Christoph 的善意提醒解决了这个问题。

要解决这个问题，请通过以下命令为 cairo 终端 安装依赖库：

sudo apt-get install libcairo2-dev
sudo apt-get install libpango1.0-dev

然后再次编译gnuplot：

#build it:
cd gnuplot-5.0.1 ; ./configure ; make

#install it:
sudo make install

现在，一切都很好。享受它:-)
