Linktime error using GRRLIB and related files Yo guys, I warn you: I began C++ coding on Thursday evening and did not do any on Friday, thus this is my second evening. I've been learning from teknecal's tuts on codemii, and am trying to splice some of that with the recent tic-tac-toe coding-assistance release. All I want to do at this stage is display a background png and have a cursor png follow the IR. I believe my code is sound, so far. I've been having trouble getting the linking to work: after much fiddling, I've got most things linking, but now I'm getting the error: c:/devkitPro/examples/wii/experiment2/source/pngu.c:1100: undefined reference to `png_get_io_ptr' Can anyone help me here? Perhaps a guide to what my dir structure should be, as well as the contents of the makefile bit for GRRLIB. I would be eternally thankful.http://forum.wiibrew.org/read.php?11,19601,19601#msg-19601Sat, 11 Jul 2026 09:51:48 +0200 Phorum 5.2.23 http://forum.wiibrew.org/read.php?11,19601,19636#msg-19636 Re: Linktime error using GRRLIB and related fileshttp://forum.wiibrew.org/read.php?11,19601,19636#msg-19636 RazorChrist CodingSun, 07 Jun 2009 05:23:04 +0200 http://forum.wiibrew.org/read.php?11,19601,19622#msg-19622 Re: Linktime error using GRRLIB and related fileshttp://forum.wiibrew.org/read.php?11,19601,19622#msg-19622
I've managed to display a background with a movable cursor on it. I might submit it and call it "Stroke Derrida".]]> alainvey CodingSun, 07 Jun 2009 04:10:17 +0200 http://forum.wiibrew.org/read.php?11,19601,19614#msg-19614 Re: Linktime error using GRRLIB and related fileshttp://forum.wiibrew.org/read.php?11,19601,19614#msg-19614
root dir (where makefile is)
 -- source (where main app/game source files go)
 ---- gfx (where all images go)
 ---- GRRLIB
 -------- fonts (folder)
 -------- GRRLIB.c
 -------- GRRLIB.h
 ---- libpng
 -------- pngu (folder)
 -------- png.h
 -------- pngconf.h
 -- lib (library files)
 ---- libpng.a

As far as your error goes, can you post the part of your code that uses that reference? I would also look at the code in the pngu.c file on line 1100, make sure you don't have anything misspelled.]]> RazorChrist CodingSun, 07 Jun 2009 03:19:07 +0200 http://forum.wiibrew.org/read.php?11,19601,19601#msg-19601 Linktime error using GRRLIB and related fileshttp://forum.wiibrew.org/read.php?11,19601,19601#msg-19601
