- Short: IXemul 44.0 - various utilities
- Author: various
- Uploader: fnf@ninemoons.com
- Type: dev/gcc
-
- This is ixemul.library release 44.0, a shared library that makes it possible
- to compile and run most Unix programs under AmigaOS with almost no changes.
- IXemul is part of the ADE (Amiga Developer's Environment), a community
- effort to produce a complete development environment that is stable,
- available in source, and completely self-hosting. See the ADE readme file
- at ftp://ftp.ninemoons.com/pub/ade/README for more details about ADE.
-
- As of version 43.1, IXemul includes Jeff Shepherd's networking code. If
- ixnet.library (included) is installed then ixemul.library will use the
- networking functions from the ixnet.library, instead of the default dummy
- implementation. Ixnet.library works with AS225 and with AmiTCP. It
- supports both clients and daemons. A program that uses networking functions
- is completely shielded from the AS225 and AmiTCP differences by
- ixnet.library, which will take care of all the details for you. That means
- that there is no longer any need to provide two different binaries, one for
- AS225 and one for AmiTCP. Furthermore, it is relatively easy to add support
- for other network packages.
-
- The following are the changes made since the 43.1 release:
-
- Kriton Kyrimis updated ixprefs.
-
- David Zaroski updated ixtrace.
-
- Fixed link count for directories. Thanks to Norbert Pueschel.
-
- umask implemented for for open() and mkdir(). Thanks to Norbert
- Pueschel.
-
- Added muFIBB_SET_GID, which will be implemented in the next
- version of MultiUser. The old way of handling setgid was
- confusing and even potentially dangerous. Thanks to Norbert
- Pueschel.
-
- Added the translation unix sticky bit -> AmigaDOS h bit. This one
- is more for aestaethical reasons, as the h bit is no longer
- supported in 3.x. Thanks to Norbert Pueschel.
-
- Added a field 'void *u_user;' near the beginning of the user
- struct which everybody is free to (ab)use. It can be handy to
- store task private data in the user struct, at least, I had to
- use it recently.
-
- Added an ix_amiga.h header, which will contain all amiga specific
- functions and macros in ixemul.library and libc.a, together with
- a description.
-
- Profiling has been enhanced. Ixprefs adds a new profiling
- preference: either take samples only while your program is
- running and the PC is within your program, or take samples while
- your program is running and if the PC is outside your program
- code (e.g. in ixemul or in intuition.library), use the last
- function your program entered before calling ixemul or whatever,
- or always take samples, even if other programs are running.
- Again, the last recorded function gets the hit in those cases.
-
- An array of 100 longs to store the A4 register of shared
- libraries has been added to the user struct. This array can be
- easily increased in future releases, should the need arise. The
- first 20 slots are for your own free use, the other slots should
- be registered. See the file REGISTRY in the ixemul source
- distribution for more details.
-
- Fixed yet another path bug. Running a shell script that's placed
- somewhere in your PATH from 'make' failed, unless the filename of
- the script was absolute.
-
- Added vfork_setup_child to libc.a. This is a wrapper intended to
- make life just a little bit easier for those who need to use the
- vfork2()/vfork_resume() trick. It replaces the old
- 'ix_resident()/ix_get_vars2()' pair.
-
- Fixed more problems with the routines that start a shell
- script. This time problems with symbolic links have been fixed.
-
- Fixed problems when parsing a pathname of a shell script,
- preventing the execution of that script.
-
- Replaced the stdio-sources by the NetBSD 44.0 versions, which
- incidentally fixed the broken fgetpos function. This change also
- adds printf() and scanf() support for the 'long long' datatype.
-
- Added support for the O_CASE open() flag: this will open an
- existing file only if the filenames match using a case-sensitive
- comparison.
-
- fstat() didn't compensate the file time for the current timezone
- offset.
-
- Ixemul now supports the 68010 CPU. Thanks to Pascal Eeftinck for
- pointing out that the 68010 uses a 68020-like stackframe.
-
- Build the version.[ch] files in the build directory instead of in
- the source directory.
-
- Fixed fchdir().
-
- Changed the machine name as returned by uname() to "m68k". Thanks
- to Lars Hecking for this.
-
- O_ASYNC I/O is now partially supported: select() will test for
- this situation.
-
- /dev/tty is now translated to console:.
-
- Implemented pseudo-terminals support using the FIFO device.
-
- Many, mostly small, changes to become more NetBSD
- compatible. Where possible, I've replaced the old sources with
- the NetBSD 1.1 sources.
-
- The select() function has been improved: it is now much faster
- and works much better.
-
- Using F_SETFL with fcntl() failed if the file wasn't a regular
- file. It now also works for pipes and sockets.
-
- Requesters that are from ixemul.library or ixnet.library now have
- the name of the library as their title, so that you can see that
- they are from the library, and not from the application. Thanks
- to Udo Schnurpfeil for suggesting this.
-
- The tty database functions unfortunately slipped through and
- weren't included with 43.1. They are back in 44.0.
-
- Implemented mmap() and friends. Of course, any mmap feature that
- actually requires a MMU will return an error. But if mmap() is
- used to load a file into memory, then it works fine.
-
- Applied patch from Kamil Iskra to improve ixemul stack extension
- handling.
-
-
- The net ixemul library distribution consists of several archives:
-
- ixemul-bin.lha Utils for gnu/bin, like ixtrace and ixconfig
-
- ixemul-sdk.lha Files needed to build applications that use
- ixemul.library.
-
- ixemul-doc.lha Various documentation, such as this file
-
- ixemul-src.lha Complete source code for ixemul library
-
- ixemul-tz.lha Pieces for doing TZ (timezone) management
-
- ixemul-CCCF.lha Specific flavors of the library, where 'CCC'
- is one of 000, 020, 030, or 040, for 68000, 68020,
- 68030, and 68040 respectively, and 'F' is either
- 'f', 's', or 't' for FPU support or soft floating
- point or a "trace" version (also soft float)
- respectively.

- the documentation archive.
