hi olaf,


did you specify the -march flag? otherwise, can you try to enable a `native' 
build (cmake -DNATIVE=ON .)


if you cannot install, you could try to specify the plugin path manually ... to 
figure out, what is breaking your code, you could try to bisect the sc sources 
to find the commit, that breaks your code ... then it should be easy to solve 
the issue!

cheers, tim

it compiles

i can start supernova and get this:

i can not install it so i can not test it because current svn sc breaks 
something in my sc-code i`m just using :-(

which i forgot and do (without the patch)

||cmake -DCMAKE_CXX_FLAGS=-march=i686 ..

i get

hm, you version of gcc seems to be quite ancient (older than 4.2). if you would 
use a more recent gcc, you could use the NATIVE option to cmake ...

nevertheless, i have updated the wiki page with a hint to specify the -march 
flag manually [1]




possible ... i'll try and have a look!

hi olaf,

[snip]

it is currently a `stupid' jack application. no care is taken to do a proper
cleanup, if jack terminates ...


hrm ... the code seems to be generated for generic x86, meaning, that there is
no support for cmpxchg8b. in a way this is nice, because the code won't crash
the machine when running supernova on an i486 cpu ...

nevertheless, can you test this patch?

thnx, tim

first of all:
when i stop jack with qjackctl supernova does not stop:

its processing but is marked as:

it also does not reconnect to jack when i restart jack.

all channels bigger 1 are destorted in the way that the buffer is not 
written in the right way.

Re: supernova blocks super

Tim Blechmann — 2010-10-19T11:56:50

hi olaf,


some time ago, i switched from using the `supernova' branch to using the 
`master' branch. i suppose, you are still working on the supernova branch.
so i suppose, you should switch to the master branch before:
git checkout master
then:
git pull

cheers, tim

Re: supernova blocks super

olaf hochherz — 2010-10-19T11:47:38

to do this i should update supernova ... but what did i do wrong with 
git, it should be just a normal "svn checkout" and "svn update"
but git pull gives me:

$ git pull

hi olaf,


just to confirm, that i understand it correctly: if you start too many synths at 
the same time,
- scsynth gets zombified by jack
- supernova blocks the computer
?


well, the more information, i get on how to trigger the behavior, the easier for 
me to fix the bug!

thnx, tim

supernova blocks super

olaf hochherz — 2010-10-17T15:31:43

hey

one reason why i don't work with supernova in the moment is, that it is 
able to block the computer.
scsynth is not able to deliver sound to jack and gets zombified  by jack 
immediately when i start to many Synth.

are there any plans to stop supernova from beeing able to block the 
computer on a rt-kernel linux?

best
olaf
