从源代码编译Inkscape时出错

Question

Not having well knowledge on dealing with C++ projects, I have downloaded the source code of Inkscape from its GitLab repository and made few changes (adding small feature) and tried to compile based on the instruction provided in INSTALL.md and other sources available on their website.

While it seems I have all the dependencies installed on the system, I get this result after running cmake in build folder:

The relevant lines in DefineDependsandFlags.cmake:42 are:

              pangocairo

          gsl
          gmodule-2.0
          libsoup-2.4>=2.42)

As far as I checked, all these packages are already installed on my system.

Here is the content of CMakeError.log in which these lines might gives some clue:

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

I couldn't find any help from searching in Internet.
Any help would be appreciated.

I have tried compilation on both Kubuntu 17.04 and Ubuntu 16.04 LTS

There are some missing dependencies you need to install in order to compile the source code. According to your cmake results:

A required package was not found

The easiest way in Ubuntu (Kubuntu tested) is to install Inkscape development packages from the ppa repository. Type the following command in terminal then hit Enter:

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

After that you need to enable source code repository. Try to uncomment deb-src line. (Remove # from the beginning):

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

• Note that you can use your favorite text editor instead of vim.

Now update the list of packages using sudo apt update . Next you're ready to install the development packages:

sudo apt build-dep inkscape-trunk

Now it's all set to compile and run ;)
