[SOLVED] MPEG-DASH, libdash

qrange · 08-13-2013, 04:51 AM

I'm trying to install libdash in Debian_testing_amd64 using instructions for Ubuntu.

However, 'make' fails with error:

Code:

DOMParser.h:18:30: fatal error: libxml/xmlreader.h: No such file or directory

Could you please tell me how to fix it?
Anyone using libdash on Debian?

thanks.

# apt-file search xmlreader.h

.. Or use the on-line search for "libxml/xmlreader.h"
http://packages.debian.org/search?su...%2Fxmlreader.h

→ → # apt-get install libxml2-dev

P.S. : Compiling libdash.

# apt-get install g++-4.4

Assume : $ svn co https://svn-itec.uni-klu.ac.at/repos2/dash/trunk
Edit g++ in { libdash/source/defaults.mk } to g++-4.4

.. Then 'make' in trunk/libdash/libdash/ should do OK.

Will provide trunk/libdash/bin/libdash.so

unfortunately packages 'libxml2-dev' and 'libxml2-dev:386' are already installed.

I can't download from that site, it says "svn-itec.uni-klu.ac.at uses an invalid security certificate." (Error code: sec_error_untrusted_issuer)

don't have trunk/libdash/libdash/ directory.

I managed to apt-get install g++-4.4 (at least that

)

thanks.

OK, if you didn't use $ svn co <url>, then you may have a very old package.

Please try this version, libdash-svn.rev204-1.tar.bz2, 23 kB
https://docs.google.com/file/d/0B7S2...it?usp=sharing
That's the latest version, with "Linux files only",
and the "defaults.mk" already says g++-4.4 .

And : No prerequisites are required. Has internal {xml2 headers}.

thanks.
I've downloaded libdash-svn.rev204-1.tar.bz2, and now have libdash.so (560Kb).
not sure how to use it though. are there examples for it in C or similar?
which language would you recommend?

Just for information you are using a quite old version of the library the newest version (3.0) is available on github [1] including a sample application based on QT.

# 9, @c|mueller : Welcome to LQ.

Thank you. Much easier :

This new version can be compiled with a contemporary g++ (e.g. -4.7.x).

$ git clone https://github.com/bitmovin/libdash
$ cd libdash/libdash/ && mkdir build && cd build/ && cmake ../ && make
... Will provide :
libdash/libdash/build/bin/{libdash_networkpart_test, libdash.so}

qrange · 08-14-2013, 08:47 AM

oh, but that's the one I started with!
I had downloaded libdash-master.zip and tried 'make'.

Well then. The git version compiles OK in e.g. Debian Wheezy :
$ git clone https://github.com/bitmovin/libdash
$ cd libdash/libdash/ && mkdir build && cd build/ && cmake ../ && make

qrange · 08-15-2013, 01:51 AM

back to square one...

Code:

DOMParser.h:18:30: fatal error: libxml/xmlreader.h: No such file or directory

I've found xmlreader.h here:

/usr/include/libxml2/libxml/xmlreader.h
libdash-master.zip/libdash/libxml2/include/libxml/xmlreader.h

but don't know how to fix it.

thanks.

Ref. " git clone https://github.com/bitmovin/libdash "
Are you sure you did the "cmake configuring" in the right way ?
1) cd libdash/libdash/
2) mkdir build
3) cd build/
4) cmake ../
5) make

P.S.: The "libdash-master.zip" may be buggy.
Libdash was bug fixed 16 days ago: https://github.com/bitmovin/libdash

I see. the problem with github is that it doesn't work here, behind proxy. at least it didn't long time ago, I'll try again.
thanks.

edit: it worked from git clone!
I got 'libdash_networkpart_test' and 'libdash.so'. thanks again
