Re: Newbie questions - compiling Linux exes on Windows OS

Hi Dan,

Many thanks for your informative reply. Although now not
directly related to the list topic, I have just a few final
questions to resolve certain things.

Right. I did think there was a chance of that...

Is it inefficient in terms of transferring data between
server and user, or in the processing and manipulation of
data itself on the server? For example, I want to run a
conversion script where the user sends a single MIDI or a
picture to be converted. This single file is sent to the server
for complicated processing with maths and stuff, but no data
is actually being communicated between server and user until
the very end - where a single converted file is easily sent
to the user. So perhaps the inefficiency you speak of isn't
an issue in this case?

The reason I want to use C/C++ is because I eventually also want to
make the program as a standalone product so people can use it offline
aswell as online. But to avoid the hassle of compilation every
time I want to try the program out, I might use perl or PHP
after all. In this case, is perl or PHP closer to simple C/C++ code?

One other factor to use perl or PHP is the ease of use required
to test a program on my own PC. The last thing I want to do keep
uploading the program to my server in the bug-testing stage to see
if the programs works. I'd rather just test it on my own system,
and upload it at the end.

I use CoreFTP to upload to my site using SSH. If what you're saying
is as simple as I think it is, is there any instant way of performing
a compile on a file (using a shell or something), or will I need
to enquire further to obtain information to obtain the location
of the server's compiler exe?

Right, I'll probably stick with the compiler on my host. But out of
interest, if I compiled as linux/unix exe, wouldn't that be a
generic exe that would be compatible with most unix/linux
setups? If I can compile a Windows exe and assume it to run
on most Windows setups, then why can't I do the same for linux/unix?
After all, my (image/MIDI) conversion program will only use simple
maths and file accessing commands to read and write data to a file.

Tripod. Only kidding ;) I use a host called Neopages.

Cheers,
