Compiling a DMG (for mac) under window ?

[scalion]

Hi all,
I'm a new user of BBCSL, i see it's a very interesting language.
I need help on a question : Can i compiling a .DMG program (for mac) under window from a .BBC source ?
I program under Window but i have a friend who working on Mac and i want to share some program in future (for the moment i learn how BBCSDL Basic work and what can i do, I have the impression that this language is quite powerful).

I looked on this forum for a response but i dont found... I'm French and My level of English is very poor and that doesn't help me much.

Thank's for your help.

Unfortunately you can only create an Application Bundle for the platform on which BBCSDL is running. So for example if it is running in Windows you can create a .exe file and if running in MacOS you can create a .dmg file, but you cannot create a .dmg file in Windows or a .exe file in MacOS.

The technical reason for this is that building an application bundle relies on features provided by the Operating System. For example building a .exe file requires calling the UpdateResource Windows API function and building a .dmg file requires calling the hdiutil MacOS API function.

However in practice you will always want to test your program on the target platform. Although BBCSDL's cross=platform credentials are good you cannot guarantee 100% that if a program runs in Windows it will also run in MacOS, or vice-versa. For example there are differences in the filesystem: Windows will accept the backslash character (\) as a directory delimiter whereas MacOS will only accept the forward slash (/).

I purchased a relatively cheap Mac Mini to allow me to test programs on the Mac and build .dmg files. Similarly I have a dual-boot PC which allows me to run Windows or Linux, so I can test programs and build application bundles for both those Operating Systems.

Thank you for this quick response and your very complete explanations.
I understand why this is not possible.
I'm going to try with a virtualbox under Linux.
I wish you a good day.
