Cannot launch kmymoney2 - dyld: Library not loaded: /opt/local/lib/libjpeg.7.dylib

[forums@…]

When I try to launch my compiled port for kmymoney2, it fails with the following error:

strewth:opt jeffery$ kmymoney2
dyld: Library not loaded: /opt/local/lib/libjpeg.7.dylib
  Referenced from: /opt/local/lib/libkhtml.4.dylib
  Reason: image not found
Trace/BPT trap

Any ideas what I need to do to fix this linking error?

Don't forget WikiFormatting. You don't need to Cc yourself.

There is no port kmymoney2... There is a port kmymoney...

Looks like whatever port provides libkhtml.4.dylib is still linking with libjpeg.7.dylib, and needs a revision bump to force it to re-link with libjpeg.8.dylib. Can you use

port provides /opt/local/lib/libkhtml.4.dylib

to tell us what port that is so we can increase its revision to force the rebuild?

kdelibs3

kdelibs3 did already receive a revbump following the upgrade to jpeg 8; see r64763 and #23260.

Please force kdelibs3 to rebuild using:

sudo port clean kdelibs3
sudo port -n upgrade --force kdelibs3

It looks like one needs to specify the correct kdelibs3 version in kmymoney's Portfile?!

[ryandesign (Ryan Carsten Schmidt)]

Huh? There is no way to specify a version of a port in a dependency.

[mkae (Marko Käning)]

Really? Oh, I guess this is a must in a situation like this. If a user has a too old kdelibs3 one cannot shift it to the user and let her/him figure out what has to be done to get a port built...

What can be done about this?

[ryandesign (Ryan Carsten Schmidt)]

MacPorts doesn't have the infrastructure to let a user install any arbitrary version of a port. The user can only install the current version of the port. (There are instructions in the wiki for installing an older version, but that's more of a workaround and not really part of MacPorts as such, and not something most users should need to use at all.)

When jpeg was updated to version 8, all of its dependents were revbumped so that the user would be informed (via "port outdated") that they need to be rebuilt (to link with the new version of the jpeg library).

Jeffery, does kdelibs3 show up in the output of "port outdated" for you? If so, then just upgrade it and any other outdated ports as per usual (e.g. "sudo port upgrade kdelibs3"). If kdelibs3 does not show up in "port outdated", do you have any idea why your kdelibs3 is not already linked with jpeg 8? Did you deliberately downgrade any of your ports at any time for example?

[mkae (Marko Käning)]

Yep, you are right, normally this should not have happened if Jeffery would have upgraded his installation accordingly.

Please force kdelibs3 to rebuild

Jeffery, did that work?

[ryandesign (Ryan Carsten Schmidt)]

Closing due to lack of response. If rebuilding kdelibs3 did not solve this problem please let us know.
