cmake fails at biblesync - can't build on kubuntu 18.04

[mozmck]

Trying to build on Kubuntu 18.04 and not having success. I built and installed Sword from git, biblesync from git, and I installed all the other dependencies.

When running cmake for xiphos I get the following output and errors - and I can't figure out why or how to fix it. HELP!

A little more info if I use -Wdev with cmake:

CMake Warning (dev) at cmake/modules/FindBiblesync.cmake:18 (find_path):

I searched and the only instances I can find of BIBLESYNC_INCLUDE_DIRS and BIBLESYNC_LIBRARY_DIRS is in FindBiblesync.cmake where they are used. How are those variables supposed to be set?

I finally got it to work by changing XiphosDependencies.cmake to use pkg_check_modules instead of find_package. It currently uses pkg_check_modules in WIN32 but find_package in Linux. That seems backwards since pkg_check_modules uses pkg_config, and that is native on linux distributions. Anyhow, I don't know what the correct fix is here - so I'll leave this issue open for now.

It's likely that the install of Biblesync on your system installed the files to /usr/local. By default, pkg-config only looks in /usr. You could try reverting your change but exporting PKG_CONFIG_PATH=/usr/local/lib/pkgconfig before running CMake. That should tell pkg-config to also check the /usr/local prefix (or point it to wherever you installed the Biblesync files).

At least, I think that's the variable name...

[mozmck]

Well, I just checked and biblesync is installed in /usr - not /usr/local. Interestingly though, sword is installed in /usr/local and Xiphos configured and compiled just fine that way. I had problems at first with sword installed in /usr using autotools, so I tried using cmake and it put it in /usr/local by default and I just left it there.

[mozmck]

Just verified that the pkg-config default path includes /usr/local.

$ pkg-config --variable pc_path pkg-config /usr/local/lib/x86_64-linux-gnu/pkgconfig:/usr/local/lib/pkgconfig:/usr/local/share/pkgconfig:/usr/lib/x86_64-linux-gnu/pkgconfig:/usr/lib/pkgconfig:/usr/share/pkgconfig

If you want I have created a deb for Ubuntu on my ppa. Is your problem related to this commit?

[karlkleinpaste]

trying to understand if this is still a problem. i intend to release B2.0.2 with (or briefly before) the next Xiphos, as much to refresh various distros' countdown-to-death counters, there will be no new capability. is there anything actually wrong with either FindBiblesync.cmake or biblesync itself?

I had a similar issue, and it was that cmake was too old. checking Kubuntu 18.04 comes with cmake 3.10 which is below the 3.11 required. Specifying include dirs for imported modules doesn't work on earlier versions of cmake. You could try manually installing a newer version of cmake in a separate private location (by setting --prefix="~/tmpcmake"in the configure stage of compiling cmake), and setting (export) PATH to point to it before other paths, for eg. OLDPATH=$PATH; export PATH=~/tmpcmake:$PATH before trying to create xiphos package. once done, you could remove your private newer cmake and restore the PATH with export PATH=$OLDPATH

Or you can juste install the deb present in the Crosswire ppa: https://launchpad.net/~pkgcrosswire/+archive/ubuntu/ppa For 18.04 a new version of cmake is also present in this ppa.
