Hi,

If you want a fast way to rebuild dolphin then the kdesrc-build way
certainly isn't it. It will build a lot, and you only want dolphin.. So
that might be a bit overkill.
The reason it failed is probably (just guessing here) some missing that
might not be installed.

Here is how i would do it (on ArchLinux) but you can follow the same
principle in Ubuntu.

1. Install the build dependencies for a package. For ArchLinux that is a
plain simple PKGBUILD file (just a text file) followed by a "makepkg"
command. For Ubuntu "apt-get build-dep <package>" probably works.
2. Next up, get the source of the package you want to modify. Ubuntu with
apt-get probably has ways for that, but i don't know. Not an Ubuntu user
here. What i would do is clone the package in question (dolphin in this
case https://cgit.kde.org/dolphin.git/). Clone that and then checkout the
version that matches the one your Ubuntu version uses. It probably is "
16.04.3 so in the git repository you check that out with: "git checkout
v16.04.3" (you can see all tags on the dolhin url i just linked to or with
git commands.
3. Then it's time to build. Make a build folder anywhere you want. From
that folder you do "cmake <dolphin_source_folder>" then "make -j 17" (17 =
threads * 2 + 1. In my case i have 8 threads).
4. Wait :)
5. Now you have a dolphin executable

That should work.. It's my workflow if i want to test something out on a
specific version without recompiling everything.
