Gmsh 安装问题：无法启动 GUI（未找到 FLTK 库）和二进制安装弄乱了几何图形

【中文标题】Gmsh 安装问题：无法启动 GUI（未找到 FLTK 库）和二进制安装弄乱了几何图形

【英文标题】：Gmsh installation problems: cannot launch GUI (FLTK libraries not found) and binary installation messes up geometry

【问题描述】：

出于某种原因，Ubuntu 软件列出了非常旧的 gmsh (2.10.0) 版本，它没有布尔功能。我需要使用布尔运算，所以我想升级到最新的 3.0.6 版本。 apt-get 升级不起作用。

我尝试使用来自 gmsh.info 的二进制安装。从 bin 目录中输入 ./gmsh 打开 gmsh GUI 然而，它完全搞乱了几何图形（对于任何给定的 .geo 文件）。在之前的 2.10.0 版本中，相同的几何形状看起来很完美。所以我决定从源代码进行全新安装。

我设法安装了它，当我尝试时 gmsh --版本 它给了我这个：

3.0.6

所以我知道它已正确安装。

但是，如果我在终端中输入 gmsh，它不会打开 GUI。相反，它给了我一个输出：

gmsh -help

我从 cmake 日志中发现 gmsh 找不到 FLTK 库。以下是来自 cmake 的最新日志：

所以从这个日志中我知道它在定位 FLTK 库时遇到了问题（尽管我在构建 gmsh 之前安装了它）以及其他关于网格算法等的重要警告......

系统有 Ubuntu 16.04 LTS，gmsh 安装在 /opt/gmsh

有人知道问题可能是什么吗？如何启动 gmsh GUI 而不会弄乱任何几何图形？

【问题讨论】：

“构建依赖列表”packages.ubuntu.com/source/bionic/gmsh ... 说libfltk1.3-dev

感谢您的评论。但是你建议我做什么？另外，我的错误是我没有明确地说出这一点，但我确实在继续之前安装了 FLTK，看来无论如何都很难找到它..

【参考方案1】：

试试：

sudo apt-get install libfltk1.3-dev
