Hi, folks. Longtime user, firsttime poster. I've got what I think is a new problem, but probably one that will come up from other people as it's related to Ubuntu Dapper (the newest release). I updated to Dapper with no major probs, aMule worked fine, but then I recompiled from CVS. ./configure ran fine, make and make install fine, but when I tried to run it:

endgamer@cpc1-kemp1-5-0-cust10:~/new/wxGTK-2.6.3$ amule
amule: /usr/lib/libwx_gtk2u_core-2.6.so.0: version `WXU_2.6.2' not found (required by amule)
amule: /usr/lib/libwx_gtk2u_core-2.6.so.0: version `WXU_2.6.3' not found (required by amule)

Any ideas? I've tried numerous versions of the CVS, including going back to the one I had compiled before, haven't yet resorted to going back to a release version. I've also recompiled wxWidgets a couple of times from the 2.6.3 sources, seem to be no problems with that.

If anyone can offer advice I'd really appreciate it - I can usually troubleshoot from error messages but this one really doesn't give me enough to work with as far as where the problem is located....

Hello Endgamer!

aMule doesn't find the required libraries, because they are in /usr/local/ and it doesn't search there.

Add the following flag to your wxGTK-configure-command: --prefix=/usr/
Or just update your LD_LIBRARY_PATH before starting amule:
export LD_LIBRARY_PATH=/usr/local/bin:$LD_LIBRARY_PATH

I hope that solves your problems or at least give you a hint on where to search the error.

Hi Wuischke, thanks for your response,
     Unfortunately that doesn't seem to have done it - I recompiled wx with the --prefix arg, and it still didn't work, so then I recompiled amule, and that didn't fix it, then I exported the LD_LIBRARY_PATH just as you said (I copied and pasted to make sure I didn't mess it up) and it still gave exactly the same error - any other ideas?

OK, then let's ensure, that the libraries are where I thought they are:
ls /usr/local/lib | grep wx

And please excuse my mistake above, the right command is: export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

[Endgamer]

Ah-ha! Thankyou, that seems to have got it! I set the path and it worked! Now, I'm told that setting the LD_LIBRARY_PATH variable isn't actually a great idea, so how do I make sure wxwidgets goes to the right location? I definitely compiled it with --prefix=/usr/ and that didn't do it...

[wuischke]

OK, open your Makefile in the wxwindows-source-directory and check whether the first line reads prefix = /usr/
If this applies a 'make install' should copy the files to the right place.

Yes, this is right. Edit /etc/ld.so.conf instead.

Just add a line that contains nothing else than

/usr/local/lib

to the file

/etc/ld.so.conf,

afterwards run the command

/sbin/ldconfig

and you're done.

I don't recommend building wxWidgets yet again with --prefix=/usr! /usr is reserved for pre-compiled, pre-packaged software. All self-compiled software belongs to /usr/local. Otherwise you risk making your system unmanagable sooner or later.

Thankyou, both of you - you've been a great help. I'm still feeling my way around the libraries etc and any information which makes things clearer is great!
