Eliminated the two inline functions. Support for function inlining in plain C is a bit uneven. The CRC calculation is now a macro, and the thread get-by-index is a plain function.

NufxLib README, updated 2014/12/23

UNIX
|
|
====
|
|
|
|
Run the "configure" script. Read through "INSTALL" if you haven't used
|
|
one of these before, especially if you want to use a specific compiler
|
|
or a particular set of compiler flags.
|
|
|
|
You can disable specific compression methods with "--disable-METHOD"
|
|
(run "sh ./configure --help" to see the possible options). By default,
|
|
all methods are enabled except bzip2.
|
|
|
|
Run "make depend" if you have makedepend, and then type "make". This will
|
|
build the library and all of the programs in the "samples" directory.
|
|
There are some useful programs in "samples", described in a README.txt
|
|
file there. In particular, you should run samples/test-basic to verify
|
|
that things are more or less working.
|
|
|
|
If you want to install the library and header file into standard system
|
|
locations (usually /usr/local), run "make install". To learn how to
|
|
specify different locations, read the INSTALL document.
|
|
|
|
There are some flags in "OPT" you may want to use. The "autoconf" default
|
|
for @CFLAGS@ is "-g -O2".
|
|
|
|
-DNDEBUG
|
|
Disable assert() calls and extra tests. This will speed things up,
|
|
but errors won't get caught until later on, making the root cause
|
|
harder to locate.
|
|
|
|
-DDEBUG_MSGS
|
|
Enable debug messages. This increases the size of the executable,
|
|
but shouldn't affect performance. When errors occur, more output is
|
|
produced. The "debug dump" feature is enabled by this flag.
|
|
|
|
-DDEBUG_VERBOSE
|
|
(Implicitly sets DEBUG_MSGS.) Spray lots of debugging output.
|
|
|
|
If you want to do benchmarks, use "-O2 -DNDEBUG". The recommended
|
|
configuration is "-g -O2 -DDEBUG_MSGS", so that verbose debug output is
|
|
available when errors occur.
|
|
|
|
|
|
BeOS
|
|
====
|
|
|
|
This works just like the UNIX version, but certain defaults have been
|
|
changed. Running configure without arguments under BeOS is equivalent to:
|
|
|
|
./configure --prefix=/boot --includedir='${prefix}/develop/headers'
|
|
--libdir='${exec_prefix}/home/config/lib' --mandir='/tmp'
|
|
--bindir='${exec_prefix}/home/config/bin'
|
|
|
|
If you're using BeOS/PPC, it will also do:
|
|
|
|
CC=cc CFLAGS='-proc 603 -opt full'
|
|
|
|
|
|
Mac OS X
|
|
========
|
|
|
|
This works just like the UNIX version, but includes support for resource
|
|
forks and Finder file/aux types.
|
|
|
|
Tested with Xcode v5.1.1 and Mac OS 10.8.5.
|
|
|
|
|
|
Win32
|
|
=====
|
|
|
|
If you're using an environment that supports "configure" scripts, such as
|
|
DJGPP, follow the UNIX instructions.
|
|
|
|
NufxLib has been tested with Microsoft Visual C++ 12 (Visual Studio 2013).
|
|
To build NufxLib, run the "Visual Studio 2013 x86 Native Tools Command
|
|
Prompt" shortcut to get a shell. Change to the nufxlib directory, then:
|
|
|
|
nmake -f makefile.msc
|
|
|
|
When the build finishes, run "test-basic.exe" to confirm things are working.
|
|
|
|
If you want to have zlib support enabled, you will need to have zlib.h,
|
|
zconf.h, and zlib.lib copied into the directory. See "makefile.msc" for
|
|
more details.
|
|
|
|
The makefile builds NufxLib as a static library and as a DLL.
|
|
|
|
|
|
Other Notes
|
|
===========
|
|
|
|
If you want to use the library in a multithreaded application, you should
|
|
define "USE_REENTRANT_CALLS" to tell it to use reentrant versions of
|
|
certain library calls. This defines _REENTRANT, which causes Solaris to
|
|
add the appropriate goodies. (Seems to me you'd always want this on, but
|
|
for some reason Solaris makes you take an extra step, so I'm not going to
|
|
define it by default.)
|
|
|
|
Originally, NufxLib / NuLib2 were intended to be usable natively on the
|
|
Apple IIgs, so some of the design decisions were influenced by the need
|
|
to minimize memory usage (e.g. being able to get a directory listing
|
|
without holding the entire directory in memory) and interact with GS/OS
|
|
(forked files have a single filename, files have type/auxtype). The IIgs
|
|
port was never started.
