1 These are instructions for how to compile Quat 1.20 for Linux/Unix,
2Windows and Mac OSX.
3
4In general you will need FLTK 1.1 (1.0.x doesn't work) and ZLIB 1.1.4.
5You can get FLTK 1.1 at http://www.fltk.org/
6Currently, FLTK 1.1 is still in beta. FLTK 1.1.0b13 is tested and works
7well.
8ZLIB is available at http://www.zlib.org/
9It's always possible to compile a console (text-mode-only) version which
10doesn't require FLTK and C++.
11
12How to compile Quat 1.20 under Linux/Unix
13=========================================
14
15   Before you can compile Quat, you need to have FLTK 1.1 and
16ZLIB 1.1.4 compiled and installed.
17Compiling Quat should then be as easy as:
18
19./configure
20make
21make install
22
23 Fluid, the user interface designer of FLTK, is only required if you
24plan to modify the user interface (the *.fl files). Fluid is part
25of the FLTK library and should be installed on every system that
26has FLTK installed.
27
28 To configure FLTK, ./configure looks for 'fltk-config'. If it can't
29find it, it compiles as a console version only (without a user
30interface). In this case, if FLTK is installed but could not be
31found, invoke ./configure like this:
32./configure FLTK=<pathname of fltk-config>
33for example:
34./configure FLTK=/usr/local/fltk-1.1/bin/fltk-config
35All information needed about FLTK is read from fltk-config.
36
37  If you want to compile a text-only version (without a user
38interface), you can pass the option '--disable-gui' to 'configure'.
39In that case you don't need FLTK. The C++ compiler is not needed
40for the text-only version.
41
42How to compile Quat 1.20 under Windows
43======================================
44
45 Generally, you must have ZLIB 1.1.4 and FLTK 1.1 compiled with the
46compiler you want to also compile Quat.
47
48Using MinGW
49-------------
50
51 In short: All should work the same as under Unix. So see
52description above.
53
54 MinGW is a port of the GNU gcc C/C++ compiler to Windows. It's
55open source and available for free:
56http://www.mingw.org/
57
58 A tested configuration is MinGW 1.1 and MSys 1.0.6.
59(MSys is a 'Minimal System' for gcc, it includes a shell, and
60common Unix tools like 'grep' for example.)
61
62 Other links that may help:
63http://www.xraylith.wisc.edu/~khan/software/gnu-win32/
64http://agnes.dida.physik.uni-essen.de/~janjaap/mingw32/index.html
65(The second link is more informative, but a bit outdated the last
66time I visited.)
67
68 If you've downloaded and installed MinGW and MSys, compiled ZLIB and
69FLTK you can start compiling Quat.
70The advantage of MinGW is that the configure script runs as under
71Unix. So please see the section above for invoking ./configure
72Everything said there also applies to MinGW.
73
74CYGWIN Environment
75------------------
76
77 Compilation should work with the 'configure' script as under
78Unix.
79
80 Quat doesn't need the 'cygwin.dll', so it's best to compile it
81using '-mno-cygwin' (which is the default). However, Cygwin seems
82to lack the C++ headers and libraries in no-cygwin mode, so if you
83get errors that 'iostream' or 'string' cannot be found, you have
84to install these headers and libstdc++.a from the Mingw distribution.

87
88Other compilers
89---------------
90
91 I don't have any information about other compilers, sorry. But
92maybe there's a Project file for your compiler in the 'Makefiles'
93directory.
94
95 If you manage to compile Quat using another compiler, I would be
96glad to hear from you! You can send me the project file you used, and
97I can put it in future distributions of Quat.
98
99How to compile Quat 1.20 under Macintosh OS X
100=============================================
101
102 In theory, this should be possible now. FLTK 1.1 is portable to the
103Mac, and there's a gcc distribution for OS X.
104
105 However, as I don't have access to a Mac, and I even don't know it,
106I can't say any further. If you get it to run on a Mac, please send me
107an email. It would be great if somebody would offer binaries for Mac!
108
109Optimizing for Athlon using gcc
110===============================
111
112 I received this information from Marco Pfatschbacher (many thanks!)
113He writes that he tried many variants of gcc's optimization options
114on his Athlon 500, and had the best results with the following flags:
115----
116CFLAGS = -s -static -O3 -fomit-frame-pointer -Wall -mpentiumpro
117   -march=pentiumpro -fforce-addr -fforce-mem -malign-functions=4
118   -funroll-loops -fexpensive-optimizations -malign-double
119   -fschedule-insns2 -mwide-multiply

124
125Basic Installation
126==================
127
128   These are generic installation instructions.
129
130   The `configure' shell script attempts to guess correct values for
131various system-dependent variables used during compilation.  It uses
132those values to create a `Makefile' in each directory of the package.
133It may also create one or more `.h' files containing system-dependent
134definitions.  Finally, it creates a shell script `config.status' that
135you can run in the future to recreate the current configuration, a file
136`config.cache' that saves the results of its tests to speed up
137reconfiguring, and a file `config.log' containing compiler output
138(useful mainly for debugging `configure').
139
140   If you need to do unusual things to compile the package, please try
141to figure out how `configure' could check whether to do them, and mail
142diffs or instructions to the address given in the `README' so they can
143be considered for the next release.  If at some point `config.cache'
144contains results you don't want to keep, you may remove or edit it.
145
146   The file `configure.in' is used to create `configure' by a program
147called `autoconf'.  You only need `configure.in' if you want to change
148it or regenerate `configure' using a newer version of `autoconf'.
149
150The simplest way to compile this package is:
151
152  1. `cd' to the directory containing the package's source code and type
153     `./configure' to configure the package for your system.  If you're
154     using `csh' on an old version of System V, you might need to type
155     `sh ./configure' instead to prevent `csh' from trying to execute
156     `configure' itself.
157
158     Running `configure' takes awhile.  While running, it prints some
159     messages telling which features it is checking for.
160
161  2. Type `make' to compile the package.
162
163  3. Optionally, type `make check' to run any self-tests that come with
164     the package.
165
166  4. Type `make install' to install the programs and any data files and
167     documentation.
168
169  5. You can remove the program binaries and object files from the
170     source code directory by typing `make clean'.  To also remove the
171     files that `configure' created (so you can compile the package for
172     a different kind of computer), type `make distclean'.  There is
173     also a `make maintainer-clean' target, but that is intended mainly
174     for the package's developers.  If you use it, you may have to get
175     all sorts of other programs in order to regenerate files that came
176     with the distribution.
177
178Compilers and Options
179=====================
180
181   Some systems require unusual options for compilation or linking that
182the `configure' script does not know about.  You can give `configure'
183initial values for variables by setting them in the environment.  Using
184a Bourne-compatible shell, you can do that on the command line like
185this:
186     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
187
188Or on systems that have the `env' program, you can do it like this:
189     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
190
191Compiling For Multiple Architectures
192====================================
193
194   You can compile the package for more than one kind of computer at the
195same time, by placing the object files for each architecture in their
196own directory.  To do this, you must use a version of `make' that
197supports the `VPATH' variable, such as GNU `make'.  `cd' to the
198directory where you want the object files and executables to go and run
199the `configure' script.  `configure' automatically checks for the
200source code in the directory that `configure' is in and in `..'.
201
202   If you have to use a `make' that does not supports the `VPATH'
203variable, you have to compile the package for one architecture at a time
204in the source code directory.  After you have installed the package for
205one architecture, use `make distclean' before reconfiguring for another
206architecture.
207
208Installation Names
209==================
210
211   By default, `make install' will install the package's files in
212`/usr/local/bin', `/usr/local/man', etc.  You can specify an
213installation prefix other than `/usr/local' by giving `configure' the
214option `--prefix=PATH'.
215
216   You can specify separate installation prefixes for
217architecture-specific files and architecture-independent files.  If you
218give `configure' the option `--exec-prefix=PATH', the package will use
219PATH as the prefix for installing programs and libraries.
220Documentation and other data files will still use the regular prefix.
221
222   In addition, if you use an unusual directory layout you can give
223options like `--bindir=PATH' to specify different values for particular
224kinds of files.  Run `configure --help' for a list of the directories
225you can set and what kinds of files go in them.
226
227   If the package supports it, you can cause programs to be installed
228with an extra prefix or suffix on their names by giving `configure' the
229option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
230
231Optional Features
232=================
233
234   Some packages pay attention to `--enable-FEATURE' options to
235`configure', where FEATURE indicates an optional part of the package.
236They may also pay attention to `--with-PACKAGE' options, where PACKAGE
237is something like `gnu-as' or `x' (for the X Window System).  The
238`README' should mention any `--enable-' and `--with-' options that the
239package recognizes.
240
241   For packages that use the X Window System, `configure' can usually
242find the X include and library files automatically, but if it doesn't,
243you can use the `configure' options `--x-includes=DIR' and
244`--x-libraries=DIR' to specify their locations.
245
246Specifying the System Type
247==========================
248
249   There may be some features `configure' can not figure out
250automatically, but needs to determine by the type of host the package
251will run on.  Usually `configure' can figure that out, but if it prints
252a message saying it can not guess the host type, give it the
253`--host=TYPE' option.  TYPE can either be a short name for the system
254type, such as `sun4', or a canonical name with three fields:
255     CPU-COMPANY-SYSTEM
256
257See the file `config.sub' for the possible values of each field.  If
258`config.sub' isn't included in this package, then this package doesn't
259need to know the host type.
260
261   If you are building compiler tools for cross-compiling, you can also
262use the `--target=TYPE' option to select the type of system they will
263produce code for and the `--build=TYPE' option to select the type of
264system on which you are compiling the package.
265
266Sharing Defaults
267================
268
269   If you want to set default values for `configure' scripts to share,
270you can create a site shell script called `config.site' that gives
271default values for variables like `CC', `cache_file', and `prefix'.
272`configure' looks for `PREFIX/share/config.site' if it exists, then
273`PREFIX/etc/config.site' if it exists.  Or, you can set the
274`CONFIG_SITE' environment variable to the location of the site script.
275A warning: not all `configure' scripts look for a site script.
276
277Operation Controls
278==================
279
280   `configure' recognizes the following options to control how it
281operates.
282
283`--cache-file=FILE'
284     Use and save the results of the tests in FILE instead of
285     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
286     debugging `configure'.
287
288`--help'
289     Print a summary of the options to `configure', and exit.
290
291`--quiet'
292`--silent'
293`-q'
294     Do not print messages saying which checks are being made.  To
295     suppress all normal output, redirect it to `/dev/null' (any error
296     messages will still be shown).
297
298`--srcdir=DIR'
299     Look for the package's source code in directory DIR.  Usually
300     `configure' can determine that directory automatically.
301
302`--version'
303     Print the version of Autoconf used to generate the `configure'
304     script, and exit.
305
306`configure' also accepts some other, not widely useful, options.
