emerald rebuilding package from source. compile fails. help needed

[deepclutch]

I am rebuilding emerald theme from debian source(from a ppa). I've edited accordingly the files in debian/ directory particularly, adjusting the dependency "compiz-dev" to match the installed compiz-dev version(compiz-dev (>= 0.8.4) ) . I am totally clueless what I need to do now. I tried going to the debian/patches directory and tried patching the source! never worked!
the compile errors about some undeclared variables. Can anyone Help Me?

Now I tried building package after installing build dependencies. but, it errors as below:

I have emerald source debianized and it built successfully using dpkg-buildpackage. it compiles fine. but, only the version from ppa complains of weird errors.

[SevenMachines]

decor_quads_to_property is missing 2 decor_extents_t arguments which need to be added for compilation to succeed with newer version of compiz. You can add them yourself, it'll run, but you might want to check out emeralds git repository or something first.

Hi,
How to set those variables? and what are the values.

TIA+

[SevenMachines]

In short, i dont know, without spending time going through the code. As a guess...
decor_quads_to_property used to require 2 decor_extents_t, input and maxinput, now it also needs frame_input and frame_max_input. Perhaps you can get away with mirroring the input and maxinput values, you'd need to go investigate libdecoration and its use further to know. Now method sig is

void
decor_quads_to_property (long    *data,
       Pixmap    pixmap,
       decor_extents_t *frame_input,
       decor_extents_t *input,
       decor_extents_t *frame_max_input,
       decor_extents_t *max_input,
       int     min_width,
       int     min_height,
       decor_quad_t    *quad,
       int     nQuad);

So for instance, in main.cpp:507 we have

decor_quads_to_property(data, GDK_PIXMAP_XID(d->pixmap),
          &extents, &maxextents, 0, 0, quads, nQuad);

So the following would possible work

decor_quads_to_property(data, GDK_PIXMAP_XID(d->pixmap),
          &extents, &extents, &maxextents, &maxextents, 0, 0, quads, nQuad);

Thanks for the tip. but, before that I tried copying a latest version(0.9-2) /usr/include/compiz/decoration.h from libdecoration0-dev(only this file extracted). it compiled fine and built packages albeit throwing up some warning messages.

Original /usr/include/compiz/decoration.h is ere(the version I've installed) : http://paste.ubuntu.com/728637/

The Warning Messages more due to the failing of symlinking of known libraries. I guess? I haven't installed the packages as I know, dpkg will complain of symlinks not found.

The type of change I mentioned before allows emerald to compile and run on the current oneiric version of libdecoration0, 0.9.6. Copying an older decoration.h header to somewhere to allow something to compile will likely come back to bite you, stick with headers and libraries of the same version, otherwise errors are likely to ensue somewhere along the line.
The dpkg-shlibdeps warnings are not unusual, sometimes there a sign of something that should be fixed, sometimes a sign of something that dpkg-shlibsdeps just can't an answer to. Theres a section in

 $ man dpkg-shlibsdep

that covers what all the warnings and errors mean.

Yes. it was an idiotic try, I did. the Compiz version in this system is: 0.8.4-4 , libdecoration0-dev: 0.8.4-5
obsolete versions? since the current version reached 0.9.6 for both.
I checked http://paste.ubuntu.com/728637/ (the version of /usr/include/compiz/decoration.h in the system) and it has "decor_quads_to_property" only once declared:

int
decor_version (void);

void
decor_quads_to_property (long            *data,
                         Pixmap          pixmap,
                         decor_extents_t *input,
                         decor_extents_t *max_input,
                         int             min_width,
                         int             min_height,
                         decor_quad_t    *quad,
                         int             nQuad);

am confused if it'll work. since My understanding of Programming is almost Nil .

the distro carries this old version. I am trying to compile from git the latest available compiz at 0.9.5 as a better option.

You shouldnt need to change emerald to use the version of emerald on the libdecoration0 version you're using. Judging from your versions are you using lucid? I'll install a virtual machine and see if I get the same problem

[deepclutch]

sorry that I haven't posted about the distro- I am trying this in My Debian Testing/unstable distro.

while Oneric compiz/emerald works fine in Dell Laptop. the rebuilding scene came because of this problem.

Building emerald 0.8.8 from
http://cgit.compiz.org/fusion/decorators/emerald/

On up to date debian sid gives me no problems. Did you accidently install newer libdecoration0-dev, patches or something? Maybe the ppa is a bit non-standard, see how you go with the 0.8.8 archive or an newer version from the git repository above
