pdfcairo在gnuplot中的“​​未知或模糊的终端类型”

Question

将gnuplot从4.6升级到 5.0.1 后，遇到以下错误：

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

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

  

Cairo / pango / wxWidgets这套终端包括

     

pngcairo，pdfcairo，epscairo和cairolatex输出到文件

     

用于交互式显示的wxt如果是，则默认情况下将构建所有这些   配置脚本找到所需的libcairo，libpango，libcairo，   libwxgtk和相关的支持库要禁用这些终端：

     

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

Answer 1

我用@Christoph的亲切提醒解决了这个问题。

要解决此问题，请通过以下命令为基于cairo的终端安装依赖库：

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： - ）
