When I try and compile the latest CVS of linuxsampler I get this:

rumentResourceManager.lo -MD -MP -MF .deps/InstrumentResourceManager.Tpo -c InstrumentResourceManager.cpp -fPIC -DPIC -o .l bs/InstrumentResourceManager.o

etc etc.

I've checked the directory and SF.h isn't in the sf2/ directory. :/

Also, when I configure linuxsampler with --disable-sf2-engine, when I try and load a previously saved .lscp file, I get this in the linuxsampler terminal:

Endlessly.

Any ideas what's wrong here?

Thanks.

SF.h is from libgig, you need to update libgig to latest CVS too.

I don't know why you get that crash, sorry.

Just a heads up, I've compiled the latest libgig and the latest linuxsampler, but I still get this message.

To fix it I just copied SF.h from the libgig source into src/engines/sf2 and then changed all instances of <SF.h> to "SF.h".

But then when the linker comes along I get this:

Anyone have any ideas?

Did you remember to do "make install" in libgig?

Yep, I definatly did, and it's at the latest CVS at this time of writing.

You just copied over the sf2 header files. Thats enough for compiling, but not for linking the linuxsampler binaries. Better delete your modifications and your manually copied header files and clean install latest libgig from CVS and make sure there is no old version of libgig installed anywhere (e.g. /usr/lib and /usr/local/lib).

Thanks a lot Cuse!

I did a fresh install of both libgig and linuxsampler and also of jsampler and gigedit.

The SF2/SFZ engines cause linuxsampler to segfault whenever they're selected, is this a problem on my end or are the sf2/sfz engines not yet completely usuable?

Those 2 engines are still work in progress, theres certainly the possibility that they might crash here and there, but it should not segfault when you just select them.

Oh right cool.

What could I do to find out the cause of the segfaults?

You have to make a back trace. There are various ways to do it. the most simple one is by enabling core dumps in your shell by typing in the console before starting the sampler. After it crashed it will leave a file called "core" which can examine with and then in the gdb app typing "bt" for backtrace. But this to be useful, you have to compile libgig, linuxsampler and co with debuggin symbols turned on, eg. CXXFLAGS=-g
