Porting applications

[Bieb]

With the advent of EasyCode, I now plan to switch all my programming to Win32 ASM.  So, now that I'm doing this, what do I need to learn to port my apps written in Win32 ASM to Mac OS X and Linux (with the X window system)?

C

Bieb,

Jibz is right here, across different hardware and operating systems, you need a portable language so unless you have a strong enough stomach for JAVA, C is what you have left.

Hi Bleb,
I wanted to program asm for xwindows but there is virtually no help out there for it.  As Jibz said, it's a C world.
Actually with a grounding in masm, C is reletively easy to pick up, just the funny syntax to get used to and you seem to be looking too deep all the time, but this can't be a bad thing.

I know some basics of C, but what I mean is, I obviously won't be able to just take some Windows C code and recompile it for Mac OS or Linux.  What I mean is, what sorts of system calls, etc., will I need to learn, and where can I find some basic tutorials to get started with?

Your also programming across Intel/AMD vs Motorola uP ( microProcessors ) hardware as well as the OS hurdles.

There is an immense amount of information out there.  Do a search on xwindow programming. This is just one overview:

Hi Bieb,

There are also other problems about porting applications to other platforms. For example, the equivalent of API functions in Linux are interrupts like int $0x80

As far as Linux goes, you might want to take a look at this:

If you want the details  there's an O"Reilly book called "Understanding the Linux Kernel".
