Use Perl to port Windows DLLs to Palm OS

developerWorks writes "Porting existing Windows DLLs to Palm OS has historically been a tedious process. This article introduces you to an interesting technique that makes this process easier by using Perl. It demonstrates a Perl script that analyzes existing C source code and automatically generates many of the source files required for porting. You should be able to use the code outlined in the article to help with your own porting projects."

Writing portable code

[cpeterso]

I don't think writing Perl scripts to munge your C sources is a very safe or easy to maintain design. Everyone knows that different systems have different APIs and "quirks". I think the Linux kernel takes an interesting approach to portable code. C macros (#defines and #ifdefs) are only allowed in header files, so the C source files for the core code are exactly the same for all platforms. All the platform-specific quirks and macro workarounds are isolated to header files specific to just that platform's arch directories.
