| # COMMENTARY ON RETRO68 APPLICATION BUILD PROCESS | |
| # =============================================== | |
| # | |
| # About | |
| # ===== | |
| # Retro68, the cross-compiler toolchain for the classic 68k Macintosh (e.g. System 7), uses | |
| # cmake makefiles. I prefer to use standard makefiles. To reverse-engineer how Retro68 | |
| # builds a sample application with a custom resource file, I built the sample application | |
| # Samples/Dialog. | |
| # | |
| # Build output, and project files | |
| # =============================== | |
| # The build process for the Dialog sample outputs a Macintosh application | |
| # (i.e. a file in the classic Macintosh sense of type “APPL”) with the | |
| # following resources: | |
| # | |
| # - two CODE resources: | |
| # resource ID 0 loads (LoadSeg) CODE resource ID 1, a stub that loads CODE ID 1 and jumps to it; | |
| # resource ID 1 with the actual application code (+ Retro68 support code). | |
| # - a SIZE resource. | |
| # r. ID -1 contains information on requested memory sizes, etc. | |
| # - a DLOG resource | |
| # r. ID 128 specifies the main window’s decorations, initial size and position. | |
| # - a DITL resource | |
| # r. ID 128 specifies all of the controls on our main DLOG. | |
| # | |
| # The build process essentially builds all of these resources separately (in “binary” form), and | |
| # then combines it together (in multiple combining steps) into the file of type “APPL”. | |
| # | |
| # Samples/Dialog has the following source files: | |
| # dialog.r (DITL, DLOG, SIZE resources) | |
| # dialog.c (eventually, CODE 1 resource) | |
| # There is another resource dependency: | |
| # libretro/RIncludes/Retro68APPL.r (CODE 0) | |
| # | |
| # | |
| # The commands run by cmake to build Dialog are printed below. | |
| # ============================================================ | |
