Re: Strange problem with multi-section
Actually it is the output of obj-res. I only put section attribute at the function prototypes. Could you tell me how to figure out where is something like .data+0x1998. I can't find it in the objdump output. Or I may use some options?

Congratulations; this diagnostic is not easy to produce. The most likely way to get it is via putting a section attribute on something that is not code. (Because the name of the technique is multiple *code* sections, it's not easy to imagine why anyone might do that :-).) You probably also have to initialise some other global variable to point to that something. Where do your SECT1 and SECT2 section annotations appear? Only on functions, one hopes (and conceivably on constant data, but here there be dragons). You can track this down even more quickly by using objdump or nm to find out which of your global variables is at .data+0x1998, and looking at its initialiser.

.bss full?
Hi, I'm using multi-section code. When I'm adding more code into the project, ld tells something like: /usr/m68k-palmos/bin/ld: region datares is full (xx section .bss) Now I have 3 sections (besides the .text .data .bss). Why is .bss full? Is it because there is too many reloc entries. As I know, they should be in .data section. By the way, I didn't add any global data, just some functions. Thanks, __ Do you Yahoo!?

Strange problem with multi-section
Hi, When I multi-sectioned my C++ program, g++ has some warnings like: g2palm:.data+0x1998: warning: reloc relative to strange section 'SECT2' g2palm:.data+0x19d6: warning: reloc relative to strange section 'SECT2' g2palm:.data+0x19fc: warning: reloc relative to strange section 'SECT1' g2palm:.data+0x1a5c: warning: reloc relative to strange section 'SECT1' And when I ran it on Palm simulator, all resources, like forms, menus, labels disappeared, although it seems to be still running (I got trace output). Anybody knows the problem? By the way, can I put virtual functions into different sections? I mean, the virtual functions in the inherited class. Thanks, __ Do you Yahoo!? Yahoo!

Multi section for C++?
Hi, Due to the 64K code limit, we have to use multi-section code for Palm program. PRC-tool provides sample code for multi-section code. But it is only about C. How to do that for C++?

Re: Bitmap offscreen window larger than 64KB?
Actually I just want to create a blank bitmap for double buffer purpose, not from a resource. The pixels are generated programatically. I looked at the Palm API reference and it seems that BmpCreate can create a bitmap larger than 64K. Anybody can verify that?

Actually you cannot create any resource larger than 64kb on PalmOS, unless you do it on the memory card or split in several 64k blocks. Or I have to draw such large dynamic BMP with WinDrawPixel() directly on the screen? Urgh, that would be very ugly... You can split your resource (image or anything you want) and make blocks to render on the screen. Aaron, that's with you. :) -- J.

Re: Bitmap offscreen window larger than 64KB?
Nice finding. I also searched the old archives and somebody suggests use BmpCreate to get bitmap memory as malloc, which can be larger than 64KB.

Re: Bitmap offscreen window larger than 64KB?
Are you using FtrPtrNew to allocate storage memory to store the image data? I'm wondering whether it is efficient enough for fast rendering, if I have frequent update to the bitmap. So what is better? 1. Use BmpCreate to allocate a bitmap 64Kb for double buffer. I think performance is nice, but... 2. Use FtrPtrNew to allocate storage memory, the performance is a problem. Any suggestions? For my app, it is a large bitmap with frequent pixel update (not very frequent, like per several seconds).
