COSMIC compiler license file

[salvo5702]

Is Cosmic license delivery service still working ?

I submit the request, but I didn't get any answer!

Welcome @salvo5702, to the community!

Responsibility for the compiler’s licence file lies with the manufacturer, COSMIC Software, whom you should contact. As their website hasn’t changed significantly and still appears to be active, but I expect it may well take a few days.

However, the active user @Philipp Krause has been part of this community for a very long time and tirelessly points out that SDCC is indeed a very good alternative, which is also FOSS and requires no registration whatsoever: see, for example:

• the announcement for SDCC 4.4.0
• post 1
• post 2
• and many more interesting references to SDCC

Perhaps SDCC, possibly in conjunction with one of the available GUIs, could be an alternative for you?

In 2024, I did a comparison of the compilers targeting the STM8: http://www.colecovision.eu/stm8/compilers.shtml

While details will have changed, the basic situation is still be the same: SDCC is competitive in code size and speed, and far ahead in standard compliance.

The current release is 4.5.0, which is considered very stable - work from SDCC 4.4.0 focused on bugfixes with only few new features.

We are currently working on SDCC 4.6.0, which, also thanks to STF (German) and NGI0 (EU) funding, will bring many improvements, in particular in features relevant to safety and security (e.g. improved diagnostics, better handling of many cases that were undefined behavior in older C standards, support for the _Optional qualifier for pointer nullability (looks like via SDCC the STM8 will get support for this feature proposed by ARM even before the STM32 will get it via GCC)).
