Two bugs on Arch Linux

[yoshi-k]

• gcc wants -fpermissive as a extra argument. ( I just added it to extra_compile_args in setup.py ) Output from the failed build

• Python import fails ( output below, perhaps a hardcoded soundcard?)

The first issue should be fixed in the code, not via -fpermissive.

About the second issue: Not sure exactly. There is no hardcoded soundcard. It just uses PortAudio, which I guess uses ALSA by default on Linux - looks also like ALSA from your output. Those entries ("cards.pcm.hdmi", /dev/shm/jack..., etc.) must come from some config on your system because nothing like that is hardcoded. Do you have some ~/.alsa* or /etc/alsa* or so?

[yoshi-k]

Sorry for the long delay. By now I discovered that the second error comes directly from PortAudio, so I will first try to get the library working.

Hi, I've had the same two errors described here. As far as the first issue goes, could i try to fix the code and file a pull request ?

PS: Inspite of the log messages that are described in the second error message, the audio plays fine on my machine.

P.P.S: I'm on ubuntu 14.04

[albertz]

Hey, yes, file a pull request, that would be great!

I'm not sure if this up-to-date anymore. Please open a new bug report with the exact error. Open multiple reports if there are multiple problems. Thanks!
