11:14.20manderssonI have some questions regarding compilation of optware packages.. would this be the right forum for such inqueries?
11:25.22Jin^eLDre
11:51.23manderssonAnyone experienced in building optware packages around?
11:51.50Jin^eLDmandersson: I can't say that I am experienced in that but I did build some...
11:52.07Jin^eLDwhat to you need?
11:53.10manderssonI'm trying to build mediatomb, since the current package is crippled imho, but it is linked against libstdc++ and not uClibc++...
11:53.24Jin^eLDhehe, small world
11:53.29manderssonI'm using the super-makefile and all...
11:53.41Jin^eLDwhat target are you building for?
11:54.05manderssonbrcm-24
11:54.15manderssonI have a wl500gP
11:54.37manderssonRunning openwrt
11:54.49manderssonAll I need is mediatomb with tag-support...
11:54.54Jin^eLDwell here you go - the openwrt uclibc version does not support exceptions
11:55.00Jin^eLDmediatomb can not run without c++ exceptions
11:55.28manderssonWell, it's up and running with the package from the repository...
11:55.31Jin^eLDand if you are not running optware but running openwrt then I am not sure if an optware package will actually work if you add it to openwrt
11:55.42manderssonAnd it is not linked against stdlibc++...
11:55.59Jin^eLDwhere did you install mt from?
11:56.07Jin^eLDfrom what feed?
11:56.59manderssonoptware/openwrt-brcm24/cross/unstable
11:57.44Jin^eLDaha.. I did not know that there are optware packages for openwrt, that's cool
11:57.46manderssonAn earlier release was built with tag-support but not with PS3-support and I need both :)
11:58.29Jin^eLDso the latest package, 0.11.0-4 I think - is without taglib?
11:59.04manderssonyes
11:59.15manderssonNeither taglib nor id3lib
11:59.31Jin^eLDsec, phone
11:59.35manderssonk
12:00.04manderssonApparently someone is able to build a functional binary, I want to know how :)
12:04.19Jin^eLDre
12:05.53Jin^eLDwell you can try the following
12:06.00Jin^eLDcheck out optware
12:06.11Jin^eLDmake wl500g-target
12:06.16Jin^eLDcd wl500g
12:06.21Jin^eLDmake directories
12:06.23Jin^eLDmake toolchain
12:06.24Jin^eLDmake mediatomb
12:06.55Jin^eLDhmm, make toolchain does not do what I would expect :)
12:08.29manderssonThe configure-script fails for the wl500g-target..
12:08.48manderssonI think that it is for ppl with olegs firmware or something..
12:09.37Jin^eLDwell, I happen to be one of the meidatomb devs and I plan to build static binaries for various devices
12:10.05Jin^eLDso that those could be used on any linux based firmware if necessary
12:10.15manderssonAh, I see.
12:10.17manderssonOh
12:10.22manderssonThat would do.
12:10.40Jin^eLDbut Optware is pretty cool, a lot of devices are supported
12:11.11manderssonYeah, and apparently someone is sitting on a toolchain that manages to build mediatomb correctly..
12:11.56manderssonOh well.
12:12.09Jin^eLDthe version that worked for you - was it also from the optware feeds?
12:15.05manderssonYes. The first one was 0.11.0-1 I believe but it lacked PS3-support.
12:15.18manderssonOr if it was -2, can't remember.
12:15.21Jin^eLDI doubt that, PS3 support must be enabled in config.xml
12:15.29Jin^eLDand it does not have external dependencies
12:15.37manderssonBut there is a configure-flag right?
12:15.39Jin^eLDso PS3 should work regardless of those issues
12:15.45Jin^eLDyes but it is "on" by default
12:15.56mandersson*doh*
12:17.30manderssonNow, if I only had a time-machine to fetch the old package..
12:17.57Jin^eLDwell, eno might be around later on, he will probably have an idea on what went wrong
12:18.23manderssonGreat.
12:19.12manderssonIt would be nice to be able to built it myself as well though.
12:19.18manderssonThanks for your help.
12:19.42Jin^eLDwell usually it's quit straightforward, not sure why make toolchain did not work out for the wl500g
12:21.09manderssonI'v read about the exceptions-issues you mentioned so it is probably related to C++ apps..
12:21.32Jin^eLDyes, it's an issue with uclibc++ that oleg firmware was using, not sure what openwrt is using
12:22.25manderssonThe uclibc++ from the optware feeds
12:22.30manderssonIn this case.
12:24.14Jin^eLDwell, let's see how far I get with the static builds, but it would be of course nicer to have it working via optware
12:24.48manderssonWhen are you planning on releasing them_
12:24.50mandersson?
12:25.10Jin^eLDnot sure, so far I am working on a build env (OE based) that would allow me to build for all kinds of targets
12:25.32Jin^eLDso depends on how fast I get the setup to do what I want
12:25.39manderssonAlright
12:26.35manderssonbtw, is there support for album-art in id3-tags?
12:27.26Jin^eLDyes
12:27.39Jin^eLDbut PS3 will only show them if they are not bigger than 120x120
12:28.30manderssonGreat. Both through taglib and id3lib?
12:28.37Jin^eLDyes

15:29.02enomandersson & Jin^eLD : openwrt-brcm24 is a different target than wl500g
15:29.16enomake openwrt-brcm24-target
15:36.52Jin^eLDeno: aaah.. thanks
15:52.22manderssonI'm using the openwrt-brcm24 target
15:53.48Jin^eLDok, taglib indeed fails there
15:53.50Jin^eLDbut id3lib works
15:54.34Jin^eLDeno: how would one correctly add an "if no taglib, try id3lib" dependency to the .mk ?
15:54.39manderssonYes but I am having trouble building mediatomb and making it link against the right C++ lib
15:55.50*** join/#nslu2-linux Ragnor (n=Ragnor@dslb-084-062-092-248.pools.arcor-ip.net)
15:56.43Jin^eLDmandersson: well, if their uclibc++ can not handle exceptions then you need to link vs libstdc++
15:56.47Jin^eLD..so I think
15:58.27manderssonYes but as I mentioned before, whoever put the package in the feed managed to build an link against uclibc++ and I am able to run it so..
15:59.24Jin^eLDare you sure it did not depend on libstdc++?
15:59.36Jin^eLDmaybe libstdc++ was just pulled in and you did not notice?
16:00.30manderssonldd tells me it's uclibc++ for the binary in the feed and libstd++ for the binary I build
16:01.12manderssonAnd I don't even have stdlibc++ installed.
16:01.28manderssonThe packaged in the feed named libstdc++ installs uclibc++
16:01.38Jin^eLDhm
16:02.27manderssonJust creating a link to uclibc++ doesn't work..
16:04.03manderssonI guess I should send an e-mail to the package maintainer...
16:04.13Jin^eLDhttp://www.deadlock.dhs.org/jin/mt/bcm/
16:04.25Jin^eLDcan you try the packages I built and see what it is linked against?
16:05.14manderssonSure. Hang ong
16:06.18enoJin^eLD: taglib then id3lib logic sounds good
16:09.57manderssonuclibc++
16:10.00manderssonOk
16:10.27manderssonSo my toolchain is obviously messed up somehow
16:11.19manderssonI'm using the "MasterMakefile" to set up the build env.
16:19.09Jin^eLDeno: I am not sure how to add that logic in the .mk file
16:20.25Jin^eLDmandersson: the only thing I did was : check out optware, cd trunk, make openwrt-brcm24-target, cd openwrt-brcm24, make directories, make toolchain, make mediatomb
16:20.48enosince id3lib is in PACKAGES on all platforms, we can do:
16:21.14enoifeq (taglib, $(filter taglib, $(PACKAGES)))
16:21.21eno# use taglib
16:21.23enoelse
16:21.28eno# use id3lib
16:21.31enoendif
16:21.39Jin^eLDsounds cool,thanks
16:21.52Jin^eLDI'll see that I make a patch then, did not catch rwhitby yet
16:34.53manderssonJin: Thanks for all the help
16:35.01Jin^eLDnp
16:35.05manderssonIt turned out the problem was in using the Master Makefile...
16:35.23manderssonChecking out the toolchain manually solved the problem.

17:44.14Jin^eLDeno: when my configure tries to link with id3lib for the openwrt-brcm24 target, I get undefined reference to `std::basic_ostream and stuff like that - so something c++ related
17:44.21Jin^eLDam I missing some special flag ?

18:17.57manderssonIt only worked half-way..
18:18.03Jin^eLDI know, it failed for me too
18:18.10Jin^eLDI was not able to actually link vs id3lib for some reason
18:18.35manderssonI managed that but there are unresolved symbols at run-time..
18:19.04Jin^eLDlike what?
18:19.11manderssonbin/mediatomb: can't resolve symbol '_ZNSs6assignEPKcj'
18:19.46Jin^eLDuhm..
18:20.23manderssonDon't know if there are more since it bails there..
18:20.54manderssonBut it seems libc++ related..
