* Correct warning: cast to smaller integer type -- X_init/lispbitmap * Fixes to INTRSAFE, INTRSAFE0 and ensure TIMEOUT, TIMEOUT0 used appropriately INTRSAFE and INTRSAFE0 must clear errno before executing the library or system call because not all library calls set errno on success. Avoid casting pointers or larger integer values down to smaller ints before comparing to 0 or -1, and use NULL (a pointer) rather than 0. Fix cases where the result of the library call is a pointer rather than an int to use TIMEOUT0 instead of TIMEOUT, testing for NULL rather than -1 on timeout (errno == EINTR) * Remove useless validity check of LASTVMEMFILEPAGE_word pointer * Convert pointer arithmetic type in drawline from int to ptrdiff_t * Add NOTE warning about a 32-bit vs 64-bit issue affecting currently unused GET_NATIVE_ADDR_FROM_LISP_PTR
Maiko
Maiko is the implementation of the Medley Interlisp virtual machine, for a byte-coded Lisp instruction set and some low-level functions for connecting with Lisp for access to display (via X11) and disk etc.
For an overview, see Medley Interlisp Introduction.
See the Medley repository for
- Issues (note that maiko issues are there too)
- Discussions (Q&A, announcements, etc)
- Medley's README
Bug reports, feature requests, fixes and improvements, support for additional platforms and hardware are all welcome.
Development Platforms
We are developing on FreeBSD, Linux, MacOS, and Solaris currently on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.
Building Maiko
Building requires clang, make, X11 client libraries (libx11-dev). For example,
$ sudo apt update
$ sudo apt install clang make x11dev
$ cd maiko/bin
$ ./makeright x
- The build will (attempt to) detect the OS-type and cpu-type. It will build binaries
ldeandldexin../ostype.cputype(with .o files in..ostype.cputype-x. For example, Linux on a 64-bit x86 will uselinux.x86_64, while MacOS 11 on a (new M1) Mac will usedarwin.aarch64. - If you prefer using
gccoverclang, you will need to edit the makefile fragment for your configuration (makefile-ostype.cputype-x) and comment out the line (with a #) that definesCCforclangand uncomment the line (delete the #) for the line that definesCCforgcc. - There is a cmake configuration (TBD To Be Described here).
Building For MacOS
- Running on MacOS requires an X server, and building on a Mac requires X client libraries. An X-server for MacOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases
Building for Windows 10
Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server). See Medley's README for more.
