[alsa-devel] Results: finally got this to work! RE: is statically linking libasound supported? because if i do it, i cant open the device!

[John Utz]

forgive the top post;

(supposedly IT is gonna turn on IMAP on the exchange server for YT RSN and then i can write rfc compliant email)

i followed tiwai's recommendation and corrected my configure arguments to disable shared and enable static.

once i correctly placed the conf files on the target boxes (rh62, gentoo) i was able to have success with a statically linked app on the gentoo box; however i had a lot of grief on rh62!

on rh62, i would get a segfault parsing the pcm.conf file.

however, once i limited my static linking to libasound only instead of libasound, libc, libpthread and libdl i was able to have success on rh62 as well.


tnx for your help IWAI-san!

* Well, I meant the libasound.a you made is broken.
* When you build libasound.a without --disable-shared, it passes -DPIC
* and it's built with assumption of shared library use.

AHH! thankyou for explaining that! i am greatful for the increase in my understanding of library compilation 'dynamics' (for want of a better term :-) )

tnx for the 'schoolin''

i'll report back on my outcome.
