Welcome to ORCA/C 2.2.0! This is a release containing updates from
|
||||
community members (Stephen Heumann and Kelvin Sherlock).
|
||||
|
||||
ORCA/C 2.2.0 adds support for almost all of the new language and library
|
||||
features required by the C17 standard. It also has several other new
|
||||
features, such as additional lint checks to help identify bugs and
|
||||
portability problems. In addition to these new features, ORCA/C 2.2.0
|
||||
includes hundreds of bug fixes in the compiler and libraries.
|
||||
|
||||
The ORCA/C manual has been fully updated to cover ORCA/C 2.2.0, so new
|
||||
users should simply refer to that. Users familiar with older versions
|
||||
of ORCA/C can refer to the cc.notes file in the Release.Notes directory
|
||||
for a description of the changes between ORCA/C 2.0 and ORCA/C 2.2.0.
|
||||
|
||||
ORCA/C 2.2.0 requires a real or emulated Apple IIGS with at least the
|
||||
following specifications:
|
||||
|
||||
* 2 MB of RAM (3 MB or more recommended)
|
||||
* a hard drive or SSD
|
||||
* System 6.0.1 or later
|
||||
|
||||
ORCA/C can also be run on modern Mac, Windows, or Linux systems as a
|
||||
cross compiler by using Golden Gate, a specialized emulation tool by
|
||||
Kelvin Sherlock. It is available separately from Juiced.GS:
|
||||
https://juiced.gs/store/golden-gate/
|
||||
|
||||
If you have any questions, or if you want to get involved in ORCA/C
|
||||
development, please get in touch. The ORCA/C development project is
|
||||
hosted on GitHub, and bug reports or patches can be submitted there:
|
||||
https://github.com/byteworksinc/ORCA-C
|
||||
|
||||
Thanks to:
|
||||
* Mike Westerfield, for writing ORCA/C, releasing the source code,
|
||||
and permitting it to be updated by the community.
|
||||
* Kelvin Sherlock, for providing several patches and bug reports, and
|
||||
for writing several useful tools for modern Apple II development.
|
||||
* Soenke Behrens, for compiling a list of ORCA/C bug reports and test
|
||||
cases, which has helped me to identify and fix a number of bugs.
|
||||
* The developers of Csmith (http://embed.cs.utah.edu/csmith/), an
|
||||
automated compiler testing tool that has helped to find several bugs.
