Which API is the best for developing cross platform C++ applications

Post by e.. » Sun, 11 Feb 2001 12:23:39



Hi,

I trying to develop a small text editor like application, and I want
to make cross-platform (Linux-Windows). I've developed on widows
before using C++Builder, and it was mostly a good experience. Now,
however, I developing Java application on Linux (RedHat) using Emacs,
and I like it very very much. So, I want to develop this application
using Emacs on Linux. Since I'll be using C++ in Linux for the first
time, and developing a cross-platform application for the first time I
thought I'd ask around for the best way to do this. What are the
available APIs? Which are more suited for cross-platform development
(like use cygwin on windows), and which have RAD capabilities?

                        thanks.

Well, I'm programming in Builder too and Inprise has finally released Kylix.
Kylix makes use of the CLX (a platform-independent component library).
Although the first release of Kylix only supports delphi, they (Inprise)
will release a C++ version in august. You should check out the Inprise site
for more information about Kylix.

1. Question RE: developing cross-platform applications

Greetings, Master Coders --

I'm about to embark on a software development project in which I will be
developing an application which I want to run on several different
operating platforms (initially just *NIX variants and MS-Windows, but
eventually others -- maybe BeOs; MacOS, etc.).  It will be a network
service (think POP mail or LDAP server) so user interface issues aren't
my main concern.  What I am worried about are what I would call the
"basics": endianness, word size, how to do basic disk i/o, etc.

So as a "for instance", something as simple as an integer variable means
very different things on various systems.  Is my int a 32-bit int or a
64-bit int?  Is it big-endian, or little-endian? The answer depends on
your platform.  I obviously want to write the core code for my app in
such a way that I can get exactly what I need on all platforms without
actually rewriting the entire application for each platform.

Now I could probably work out some system of #ifdef's and #define's to
do a lot of this, but if somebody has worked a lot of this out I'd
rather not re-invent the wheel.

I am wondering if anybody out there could recommend a book or article or
web page or something that gives practical, concrete solutions to these
problems.

Oh, and before somebody suggests I just write the thing in Java -- I've
considered that, but for various reasons I'm sticking with C/C++.

Thanks in advance,

- Cedric
