To get debug symbols for Inkscape, you'll probably need to recompile it. We use cmake and it has a Debug mode which produces debugging symbols:


cmake -DCMAKE_BUILD_TYPE=Debug ../
To participate, [[Special:Userlogin|create an account]] and [[Special:Upload|upload your logos]]. A deadline will be announced once we have a better feel for how many submissions to expect. The [[moderators]] act as a jury.
This assumes that you're building everything in a build folder and the repository root is the parent directory.


If you're looking an older non-cmake version, you'll need to enable the CXXFLAGS manually.
Why participate? Your logo may end up being used on millions of works large and small, giving you exposition and recognition. You will be fully acknowledged on this website as the artist. We may also announce prizes during the course of the contest.


Debugging with GDB
Some advice and ideas:
To start debugging Inkscape with GDB, load it up:
* Don't make it too complex. See the Wikipedia article [[w:logo|logo]] for some information on what makes a good logo.
* It's all about works being used freely, merged, copied, changed, and so on. A visual metaphor that reflects this may make the most sense.


gdb path/to/inkscape
If you are confused by the wiki process, feel free to e-mail Erik at <tt>moeller AT scireview DOT de</tt>, and he will take care of things.
If you want Inkscape to start right away and your version of GDB is new enough, you can start it with


gdb path/to/inkscape -ex r
''Please note:'' it was recently decided to [[Talk:Definition/Unstable#Pushing_to_1.0|drop]] the term "Free Expression" because it was too ambiguous in our context. Thus, we don't need two different logos anymore, only a "Free Content" logo.
To keep gdb from paginating (splitting output from commands into pages, makes creating backtraces for bug reports more difficult) you can put this in ~/.gdbinit:


set pagination off
== New Creative Commons Logos ==
To use GDB's text UI, you can run gdb -tui or gdbtui.


When the program crashes you might see something like this:

To find out where the crash occurred (you might not always be able to), you should run:

Now you have activated frame 2. You can see the state of the processor registers in frame 2 and any local variables that the compiler has embedded in the debug symbols.
===Yin Yang===
"Yin Yang" by Bernhard Schillo. The shape of the logo is one half of the yin and yang symbol. I believe, this is a good basis for this logo, cause it symbolizes contradictions, which generate reality. In this case the "C" (for Culture) coexists with the "uncultured" nature. Or another possible connotation: free culture and not free culture. Human culture of property can't exist without the "seed" of free culture contained in itself and without a strong free culture on the opposition. The forces have to work together.
The Logo also reminds to the Copyright-Logo. But the circle around the "C" is not a circle. The shape indicates, that something is given back.  


(gdb) info locals
The logo should be elaborated if used. These are just my first ideas and drafts. I will think about it again when the discussion about the name is finished. And i hope, my english is understandable :)

Stepping execution and breakpoints
Sometimes, you would like to be in control of program execution instead of just letting it run wildly.


You can tell GDB to stop when it reaches a certain function, upon a certain condition, or when a value in memory changes. These are known as breakpoints and watchpoints.
== Free Content Logo ==


Stopping when a function is called:

Breakpoint 3 at 0xf657a5: file ../../src/ui/tools/select-tool.cpp, line 629.
Here is another logo proposal to illustrate the Free content idea : I made it with Inkscape, so the SVG source file is available.

Creating breakpoints that will only be stopped on once:


(gdb) tbreak foo::bar
...hope you'll like it ! :-)

Evaluating expressions
If GDB can figure out what you are talking about, it can print pretty much anything. GDB also is immune to the private boundary of a class.

A handy feature to try to determine if a heap object still exists (hasn't been delete()d yet) is to use the new GDB command info vtbl:

Revision as of 20:28, 20 May 2021

We need a "Free Content" logo that can be attached to works covered by licenses which meet the conditions defined in the Free Content Definition. This logo should consist of:

  • a symbol or sign that is the same for both logos (minor variations allowed)
  • a label, probably "Free Content"

Logos must have a vector graphics source (SVG preferred), but must be uploaded in a bitmap format (transparent PNG preferred). A good, free software vector graphics application which can handle SVG and PNG exports is inkscape. The dimensions are up to you as long as the images scale well. In order for your logo to be used, the logo itself must be free content with a reduced attribution requirement, but we can work this out with you once we have picked your logo.

To participate, create an account and upload your logos. A deadline will be announced once we have a better feel for how many submissions to expect. The moderators act as a jury.

Why participate? Your logo may end up being used on millions of works large and small, giving you exposition and recognition. You will be fully acknowledged on this website as the artist. We may also announce prizes during the course of the contest.

Some advice and ideas:

  • Don't make it too complex. See the Wikipedia article logo for some information on what makes a good logo.
  • It's all about works being used freely, merged, copied, changed, and so on. A visual metaphor that reflects this may make the most sense.

If you are confused by the wiki process, feel free to e-mail Erik at moeller AT scireview DOT de, and he will take care of things.

Please note: it was recently decided to drop the term "Free Expression" because it was too ambiguous in our context. Thus, we don't need two different logos anymore, only a "Free Content" logo.
