I'd like to build an /opt/kdevelop that's self contained and doesn't reuire or break any system dependancies. I'm looking at the instructions at https://techbase.kde.org/KDevelop4/HowToCompile and I am stuck on "Modify diffsettings.h".

Code: Select all

/usr/include/libkomparediff2/diffsettings.h

does not exist. locate shows one copy of

Code: Select all

diffsettings.h

in

Code: Select all

kdevelop-4.7.0/kdevplatform-1.7.0/plugins/patchreview/settings/diffsettings.h

, the source package.

The note reads:

Code: Select all

Kubuntu 14.10 Plasma Since we are now using QT5, we need to update a this file

But I don't know if I am using QT5, I know I'm not using Kubuntu of the KDE environment, I'm running Linux Mint with the Mate desktop. The packaged kdevelop runs but is out of date.

So, do I need to update this file or not? And do I need a QT version to go into my /opt/kdevelop? Or... ?

So I ignored the part about QT5 and compiled kdevelop platform and kdevelop in /opt/kdevelop.

I can run the new kdevelop fine as root, but trying to run as a normal user cause it to crash imediatly.

There is a note in the install docs:

Code: Select all

Also, splash.qml needs to be copied to the /usr/share/kdevelop directory, otherwise the version of kdevelop will crash. or create a symlink

Code: Select all

ln -s /home/<your user name>/kdevelop4/share/kdevelop/ /usr/share

But splash.qml only exists in the build directory.

Code: Select all

kdevelop-4.7.0/app/splash.qml

Here's the crash log:

Code: Select all

OK, moving along, It seems that deleting the kdevelop files in /home/user/.kde/share/config/ and /home/user/.kde/share/apps/ fixes the crash on startup issue.
