ardour build with vst support.

Hey,

I been trying to build Ardour with vst support but I get this error message:

Does anyone know what /usr/bin/ld: cannot find -lfst means?

Re: ardour build with vst support.

"/usr/bin/ld: cannot find -lfst" means that it didn't found libfst.

You need to install fst before building ardour with fst support. There's no package so you'll need to build it: http://linuxaudiosystems.com/fst/

Re: ardour build with vst support.

I do have fst-1.7 installed and I use it as a standalone to run vst programs.
some vst plugins needs a vsthost that's why I want to build Ardour with vst support.
where would I find the libfst?

Thanx Snowman. Me being from Toronto, I should be Snowman2 after the storm a few days ago. big_smile

Re: ardour build with vst support.

Where did you installed fst? I would assume that it would come with fst.
Search your system for it:
# updatedb
# locate libfst

Re: ardour build with vst support.

Hey Snowman, thanx again.
I looked at the Sconscript in Ardour and the one from the fst-1.7. I then edit the fst/vst section of the Ardour Sconscript.
Now I get this:

Re: ardour build with vst support.

Looks like it can't find the vst header files. Were they also installed? And where? Maybe you'll need to add an argument to scons so that it can find them.

Re: ardour build with vst support.

Yeah, that's what i was thinking but the vst files are in the .../ardour-0.99.1/libs/ardour/vst.

this seems to be the file in question:
