Installation:
=============

As with any autoconfiguring GNU software, installation is as easy as this:

$ ./configure
$ make
$ make check
$ make install

You need GNU make. On HP-UX, you also need GNU sed.

Known to work with:
  - Linux/x86, gcc-3.x, gcc-4.[0-2].x
  - Linux/x86_64, gcc-3.[3-4], gcc-4.[0-2].x, gcc-4.3.0
  - Linux/ia64, gcc-3.[2-4], gcc-4.[0-2].x
  - Linux/arm, gcc-3.[0-3] (*), gcc-4.[0-2].x (*)
  - Linux/mips, gcc-3.3, gcc-4.[0-2].x
  - Linux/sparc, gcc-3.[1-3], gcc-4.[0-2].x
  - Linux/alpha, gcc-3.[0-3], gcc-4.[0-2].x
  - Linux/powerpc, gcc-3.[0-3], gcc-4.[0-2].x
  - Linux/hppa, gcc-4.2.x (*)
  - Solaris 2.4 (sparc), gcc-3.[1-3], gcc-4.[0-2].x (*)
  - OSF/1 V4.0 (alpha), gcc-3.1
  - Irix 6.5, gcc-3.0
  - OS X Leopard (x86), gcc 4.0.1

(*) On these platforms, problems with the assembler routines have been
reported. It may be best to add "-DNO_ASM" to CPPFLAGS before
configuring.

Using gcc-4.2, the "make" step takes about 15 minutes, on an x86_64 / 2 GHz.

If you use g++ from gcc-3.0.4 or older on Sparc, add either "-O", "-O1" or
"-O2 -fno-schedule-insns" to the CXXFLAGS. With full "-O2", g++ miscompiles
the division routines. Do not use gcc-3.0 on Sparc for compiling CLN, it
won't work at all.

More detailed installation instructions can be found in the documentation,
in the doc/ directory.
