 Cross platform development strategy Hello,
I am writing C programs that need to run on both Windows and Solaris. I
want to write code on either one of these platforms and have them
compile on both without a lot of work. What is the best strategy to
ensure portability of C code? I am searching on web to find this
information.
What compilers/tools can I use to achieve this portability?
Is it possible to generate executables for all platforms while working
on the windows platform?
Please forgive me if my questions are oblique, I am a newbie.
Thanks.

The C Programming Language has been standardized (especially at C89).
Use the standard and write C programs according to it. Use compilers
that respect this standard on all platforms.

Perhaps, but not here. This is Usenet, a service of Internet. The 'web'
is another thing and very off topic here.

Those are called cross-compilers. Several exist. Go look. Good luck.

This answer is highly misleading. This is the appropriate
newsgroup for the OPs questions; in fact his objectives are the
objectives of this group.

Write programs in strict compliance with the C standard.
Quote: > What compilers/tools can I use to achieve this portability?
Any compiler that will compile standard C code. I have had good
luck lith the Solaris C compiler; and you can use either
Microsoft or Gnu C compiler (or any of a number of others) on
your Windows platform. I installed the Cygwin package (which
provides X-windows) on my Windows box so that I could have a
familiar *nix-like development environment and use my favorite
editor (nedit)
Quote: > Is it possible to generate executables for all platforms while working

I suspect, but am not sure, that there is a gcc/solaris
cross-compiler that will run on a windows box. You'll need to
check in a Gnu newsgroup for this one, unless someone here knows
and is willing to help or redirect.

Not a problem. For Unix/POSIX questions you may find
before posting.

The best strategy is to write it in standard-conforming portable C code,
which means you don't use any system-provided functions except those
specified by the C standard, and you make no assumptions about the operating
environment except those specified by the C standard. Read the comp.lang.c
FAQ. You can post reasonably-small complete compilable programs here and the
regulars of comp.lang.c are very good at picking code apart and making it as
portable as possible.
Quote: > What compilers/tools can I use to achieve this portability?
Any (hosted) standard C implementation will do. Chances are there are
several that you can download for free for your implementation -- this
definitely goes for both Solaris and Windows. I think there is a list in the
C FAQ (if not there should be) but if not then google away -- off the top of
my head, Cygwin (which includes GCC), MinGW32, DJGPP, LCC-Win32, and
Borland's Turbo C 2.01 and BCC 5.5 are all free.
Quote: > Is it possible to generate executables for all platforms while

Yes. Some compilers, for example gcc, can be built as a cross-compiler that
can produce many types of executable. Investigate this in the documentation
for your particular C implementation. How to use a particular compiler is
off-topic here, and should be taken to the relevant newsgroups or mailing
lists for that compiler.

Restrict yourself to the features described in K&R2 (if possible) and
your code will work without any problems on one platform, after being
developed and debugged on the other. Especially if you don't make any
assumptions about the endianness of the implementation.
If this is not possible, expect to have portability problems. To make
the job easier, carefully isolate the non-portable parts.
Quote: >What compilers/tools can I use to achieve this portability?
The portability depends on your code, not on the tools.
Quote: >Is it possible to generate executables for all platforms while working
>on the windows platform?
Probably not, but you really don't want to do that, even if it were
possible. Cross-developing is not for the beginners.

I fear you misunderstand me my friend. My comment was an attempt to
differentiate usenet and the web in the context of the Internet. It was
a feeble attempt and I'll think more about it before I comment on the
subject again.

# Hello,

For my work I split it into system independent code which includes most everything,
and system dependent included code. The interface defines what is needed to be done
not how it is done. The system dependent code is include files, each system its own
file in its own directory named for the system. The .c file includes
"quelque-chose.sys" and in the make I can do "cc -Iinclude/$(uname)".
The usual method however to use alot of defines and #ifdefs.
# What compilers/tools can I use to achieve this portability?
Others like to use gnu configure.
# Is it possible to generate executables for all platforms while working
# on the windows platform?
Depends if you have a cross compiler.
