Ardour trouble

[manic_b]

Hey all,

Ardour2 and Ardour3 are both hanging and/or crashing on opening. I haven't really looked at them before so I don't know if this has broken recently or was broken out of the box. Running from terminal, the output is impressively unhelpful, and much the same for both versions:

The best I've found googling this is "it's a plugin" which is of little help when I've got the entire KXStudio meta packages installed! Has anyone else run into this?

Same error messages, and it does start succesfully.

Running without LADSPA same problem. Running without VST, it starts up and also opens a log window with:

Code: Select all

Recording and playback work ok though, so that error may be nothing.

[manic_b]

It's about 26MB! It does look like dssi-vst is the culprit. Is there a way to exclude it from the path for Ardour?

[manic_b]

After a bit more poking:

LV2_PATH=/NOT works
and/or
VST_PATH=/NOT works

Presumably the issue lies in an interaction between an LV2 and the VST path.

I have an strace output file without LADSPA, but it's still about 16MB. I've tried to update the kxstudio paste but it doesn't want to upload. Grab it here.

[manic_b]

Yes, that seems to have done it! Thanks falktx

For some reason i'm having similar problems but looked in package manager and nothing with naspro was installed.

Well I tryed running

Code: Select all

    export LADSPA_PATH=/NOT
    export VST_PATH=/NOT
    ardour3

Like you siggested and it still didnt run. This was in the ardour log.

Code: Select all

I'm just not sure where to start looking for problems. I'm not sure exactly what you need



Edit.... i messed around with some drivers and got it going.
Sometimes I think your adding bugs to kxstudio to mess with me personally. I know it isn't true but I've started calling them The FaulkU bugs.

A shell aside...

Instead of

Code: Select all

export LADSPA_PATH=/NOT
export VST_PATH=/NOT
ardour3

You could do

Code: Select all

LADSPA_PATH=/NOT VST_PATH=/NOT ardour3

That way the variable assignments are valid only for that invocation of the command which follows them on the same line and no change to the environment apart from that invocation. No need to unset them or start a new shell or log out/in when trying different combinations.

Code: Select all

$ cat ./boo # the demo script
echo $fig $big
$ 
$ export fig=bag big=sag # set the env
$ echo $fig $big 
bag sag
$
$ fig=3 big=4 ./boo # but use these values for this invocation
3 4
$
$ ./boo # back to the env...
bag sag
$

It's been a decade. I simply don't remember all the rules and implications of exporting a shell variable, but I do remember that programmers in other languages love to export everything in the shell (just in case) and that it is actually better only to do so when you know you need to.
