RE: How to build GTK+ AP for ARM based of Linux platform at x86 machines
Hi, Could you help to solve this problem? I use arm-gcc-4.1.2-glibc-2.5 to compile GTK application in scratchbox. That system will display these error messages. It seems GTK library EABI version not upgrade to version 4 or other problems. /scratchbox/compilers/arm-gcc-4.1.2-glibc-2.5/bin/../lib/gcc/arm-none-linux-gnueabi/4.1.2/../../../../arm-none-linux-gnueabi/bin/ld: ERROR: Source object /usr/lib/libgtk-x11-2.0.so has EABI version 0, but target example has EABI version 4 /scratchbox/compilers/arm-gcc-4.1.2-glibc-2.5/bin/../lib/gcc/arm-none-linux-gnueabi/4.1.2/../../../../arm-none-linux-gnueabi/bin/ld: failed to merge target specific data of file /usr/lib/libgtk-x11-2.0.so How to solve this problem please give me suggestion?

For example have a loot at scratchbox.org. The advantage is, that it contains all libs etc. already compiled for arm. So for compiling to arm you don't have to do anything special anymore. It's like compiling for x86. I hope I didn't miss the point of your post ;) Conny On Thu, 2009-04-09 at 13:51 +0800, Aries Huang wrote: Hi, Could you help to solve this problem?

Re: Pass more widgets as gpointer.
On Tue, Apr 21, 2009 at 08:57:41AM +0400, Vlad Volodin wrote: Hello, Jens The other way is to make your widgets global. Especially, me? I use GOjects, and always pass self object. For example, I inherit main window object from GtkWindow and later in widgets definition pass itself to callback. Also, you can use g_object_set_data for storing some useful pointers. Don't use global variables, they make the code hard to read and difficult to understand the context of the variables. Good luck 2009/4/20 Jens Hansen jensh...@gmail.com: Hello All. I'm quite new to C, but have done some gtk programming in perl. I've been looking for answers on the web, and in various tutorials, without any luck. My question is how to pass more widgets as a gpointer, to a callback function. (in C ) For instance if a OK button, has to read the state of three other widgets... In perl I would make an array of the widgets, and then pass the ref as the data argument to the callback. I cannot grasp how to do something like that in C. A typical approach to this is to create a FooContext structure that will hold pointers to all the elements that you need to use in your callback. You can instanciate it with g_new0() and later free it with g_free(). Be careful to hold object references and release them when you don't need them anymore. You could also use an array for this, but I prefer the structure approach, since you don't want to rely on the order you put the elements in the array later when you use them, removing/adding more elements you may need in the future can be a little cumbersome, etc. Claudio An example snippet would be really helpfull.

Strange GHashTable behaviour
Hello, I'm experiencing strange GHashTable behaviours when looking up a value throught a string key. I pass the key as a stack-allocated string to the hash table. For most lookups it works flawlessly but sometimes I get an invalid pointer. It even looks normal but data can't be accessed at that address. I have about 50 unique UUID keys and I'm inserting them to the hash table one by one with an associated data pointer. AFAIK, g_hash_table_lookup() should return NULL when the element with the provided key was not found in the table. So, does anyone have an idea what is going on here? Please help.
