- doc/*, INSTALL: Mention that both shared and static library are
  now build by default.

1 Installation:
2 =============
3
4 As with any autoconfiguring GNU software, installation is as easy as this:
5
6 $ ./configure
7 $ make
8 $ make check
9 $ make install
10
11 You need GNU make. On HP-UX, you also need GNU sed.
12
13 Known to work with:
14 - Linux/x86, gcc-2.7.0, gcc-2.7.2, gcc-2.8.0, egcs-1.1, gcc-2.95
15 - Solaris 2.4 (sparc), gcc-2.7.0, gcc-2.7.2, egcs-1.1, gcc-2.95
16 - OSF/1 V4.0 (alpha), egcs-1.1, gcc-2.95
17 - Irix 5.3, CC 4
18
19 The "make" step takes about 4 hours, on a 486 DX / 33 MHz / 8 MB.
20
21 On Linux, g++ needs 15 MB to compile the tests. So better have
22 17 MB swap space and 1 MB room in $TMPDIR.
23
24 If you use gcc and g++ version 2.7.x, don't add -O2 to the CXXFLAGS, because
25 "g++ -O" generates better code for libcln.a than "g++ -O2".
26
27 If you use g++ version 2.8.x or egcs-2.91.x (a.k.a. egcs-1.1) or gcc-2.95.x,
28 I recommend adding "-fno-exceptions" to the CXXFLAGS. This will likely
29 generate better code.
30
31 If you use g++ version egcs-2.91.x (egcs-1.1) or gcc-2.95.x on Sparc, add
32 either "-O", "-O1" or "-O2 -fno-schedule-insns" to the CXXFLAGS. With full
33 "-O2", g++ miscompiles the division routines. Also, if you have g++ version
34 egcs-1.1.1 or older on Sparc, you must specify --disable-shared because g++
35 would miscompile parts of the library.
36
37 On MIPS (SGI Irix 6), pass option "--without-gmp" to configure. gmp does
38 not work when compiled in "n32" binary format on Irix.
39
40 More detailed installation instructions can be found in the documentation,
41 in the doc/ directory.
