4 As with any autoconfiguring GNU software, installation is as easy as this:
11 You need GNU make. On HP-UX, you also need GNU sed.
14 - Linux/x86, gcc-2.95.x, gcc-3.[0-4]
15 - Linux/x86_64, gcc-3.[3-4]
16 - Linux/ia64, gcc-2.96, gcc-3.[2-3]
17 - Linux/arm, gcc-2.95.3, gcc-3.[0-3]
19 - Linux/sparc, gcc-2.95.3, gcc-3.[1-3]
20 - Linux/alpha, gcc-2.95.x, gcc-3.[0-3]
21 - Linux/powerpc, gcc-2.95.x, gcc-3.[0-3]
22 - Solaris 2.4 (sparc), gcc-2.95, gcc-3.[1-3]
23 - OSF/1 V4.0 (alpha), gcc-2.95, gcc-3.1
24 - Irix 6.5, gcc-2.95.x, gcc-3.0
27 The "make" step takes about 30 minutes, on a P-III / 1 GHz / 512 MB.
29 If you use g++ gcc-2.95.x or gcc-3.x, I recommend adding "-fno-exceptions"
30 to the CXXFLAGS. This will likely generate better code.
32 If you use g++ from gcc-3.0.4 or older on Sparc, add either "-O", "-O1" or
33 "-O2 -fno-schedule-insns" to the CXXFLAGS. With full "-O2", g++ miscompiles
34 the division routines. If you use g++ older than 2.95.3 on Sparc you should
35 also specify --disable-shared because of bad code produced in the shared
36 library. Also, do not use gcc-3.0 on Sparc for compiling CLN, it won't work
39 If you use g++ on OSF/1 or Tru64 using gcc-2.95.x, you should specify
40 --disable-shared because of linker problems with duplicate symbols in shared
41 libraries. If you use g++ from gcc-3.0.n with n larger than 1, you should
42 not add -fno-exceptions to the CXXFLAGS, since that will generate wrong code
43 (gcc-3.1 is okay again, as is gcc-3.0).

46 in the doc/ directory.
