从源代码编译 Inkscape 时出错

Question

对处理C++项目不太了解，我从GitLab repository下载了Inkscape的源代码，做了一些改动（添加了小功能），并尝试根据INSTALL.md中提供的指令进行编译以及他们网站上提供的其他资源。

虽然我似乎已经在系统上安装了所有依赖项，但在构建文件夹中运行 cmake 后我得到了这个结果：

DefineDependsandFlags.cmake:42 中的相关行是：

pkg_check_modules(INKSCAPE_DEP REQUIRED
              harfbuzz
              pangocairo
          pangoft2

          gsl
          gmodule-2.0
          libsoup-2.4>=2.42)

据我检查，所有这些软件包都已安装在我的系统上。

这里是CMakeError.log 的内容，这些行可能会提供一些线索：

/usr/bin/cc   -DCHECK_FUNCTION_EXISTS=pthread_create    CMakeFiles/cmTC_d21be.dir/CheckFunctionExists.c.o  -o cmTC_d21be -rdynamic -lpthreads

我在 Internet 上搜索时找不到任何帮助。
任何帮助，将不胜感激。

我已经尝试在 Kubuntu 17.04 和 Ubuntu 16.04 LTS 上编译

为了编译源代码，您需要安装一些缺少的依赖项。根据你的 cmake 结果：

A required package was not found

在 Ubuntu（Kubuntu 测试）中最简单的方法是从 ppa 存储库安装 Inkscape 开发包。在终端中输入以下命令，然后按 Enter：

sudo add-apt-repository ppa:inkscape.dev/trunk

之后，您需要启用源代码存储库。尝试取消注释deb-src 行。 （去掉开头的#）：

sudo vim /etc/apt/sources.list.d/inkscape_dev-ubuntu-trunk-zesty.list

• 注意，您可以使用自己喜欢的文本编辑器代替 vim。

现在使用sudo apt update 更新软件包列表。接下来就可以安装开发包了：

sudo apt build-dep inkscape-trunk

现在一切都准备好编译和运行了；）
