#6 undefined references when configured with --disable-jack

[Karl Lindén]

When configuring synthv1 (SVN trunk) with ./configure --disable-jack, make gives the following error:

please note that the default combined build is not effective when you either configure --disable-jack or --disable-lv2.

please follow, in either case,

a. to build the jack standalone client and only:

./configure --disable-lv2
make jack
make install_jack

b. to build the lv2 plugin and only:

./configure --disable-jack
make lv2
make install_lv2

hth.
cheers

In my opinion jack should not be included in all targets if --disable-jack is given. Likewise for lv2. I'm attaching a patch that will let them to be conditionally included in all targets.

[Rui Nuno Capela]

brilliant! i'll apply and commit right away. :)

thanks

[Rui Nuno Capela]

fixed on svn trunk [r131]
thanks

[Karl Lindén]

Perfect! Thank you very much!
