Re: [PD] Developing a python-mysqql-database-soundfile-player was: accessing mysql database

accessing mysql database
by Luigi Rensinghoff 14 Apr '07

14 Apr '07

Hi List, i successfully installed "py/pyext" on an intel macbook, and got pyhton, mysql and mysqldb running. The patch by georg holzmann i was trying to use is attached. Since i have no clue about python and sql and all of that i need some help to get started. i managed to create a database with mysql, its called "sfx_database" but when i try to connect via the patch i get the error: PD mysql: could not log into MySQL server in python i imported MySQldb, i think that is necessary and i executed dir(MySQLdb), but i am not sure if it is really loaded. Who could help me debug/troubleshoot that ??

pd with Boodler
by ryan holsopple 13 Apr '07

13 Apr '07

Has anybody used netsend to activate agents using the listen.agent [module.Class] in the python based Boodler? I have been able to send messages with netsend, but the agent one doesn't seem to work. This question may be a bit out of date, sorry. Thanks, Ryan

Hi list, this is to announce that PureMeasurement is now at version v12III07 and can be downloaded from http://www.hoertechnik-audiologie.de/downloads/PureMeasurement_v12III07_for… Important things to note: - you need a recent iemlib (should work with 1.17) - data will now be saved as 32bit floating point wav files (except pm_recorder2ch, where the user can choose between 16/24bit fixed point and 32bit floating point) --Matthias

get patch path
by Patco 13 Apr '07

13 Apr '07

I tried the python os.getcwd() function but it outputs path names with '////' instead of '/'. (Anyway the py external has problems i don't understand right now, it works when i run it with double-clicking on the patch but give me 'AttributeErrors' when I open the patch or create the py object from pd on win32). Is there another solution for getting the path of a patch or at least the working directory's path?

statically linking externals to external libs
by forwinder 12 Apr '07

12 Apr '07

Hi folks, I finished this external a few weeks back. http://www.forwind.net/forwind.net/software.htm To compile I used flext and as an external library I used SndObj. With flext I initially dynamically linked to the libsndobj.so using libs += -lsndobj. This seemed to work at the time. last week I was messing with my SndObj install. Now I cannot compile or load the external which previously had worked fine. Therefore to get around this I was hoping to statically link the SndObj library to the pure data external during compilation. Firstly has anyone had any experience with external libraries and externals using flext. And if so what would be your advice. I am running ubuntu linux and pure dyne linux. I am tempted to dump the whole flext thing and just compile for pure data on linux using something like ANT. Conor
