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-3.x, gcc-4.0.x, gcc-4.1.[0-1]
15 - Linux/x86_64, gcc-3.[3-4], gcc-4.0.x, gcc-4.1.[0-1]
16 - Linux/ia64, gcc-3.[2-4], gcc-4.0.x, gcc-4.1.[0-1]
17 - Linux/arm, gcc-3.[0-3], gcc-4.0.x, gcc-4.1.[0-1]
18 - Linux/mips, gcc-3.3, gcc-4.0.x, gcc-4.1.[0-1]
19 - Linux/sparc, gcc-3.[1-3], gcc-4.0.x, gcc-4.1.[0-1]
20 - Linux/alpha, gcc-3.[0-3], gcc-4.0.x, gcc-4.1.[0-1]
21 - Linux/powerpc, gcc-3.[0-3], gcc-4.0.x, gcc-4.1.[0-1]
22 - Solaris 2.4 (sparc), gcc-3.[1-3]
23 - OSF/1 V4.0 (alpha), gcc-3.1
27 The "make" step takes about 30 minutes, on a P-III / 1 GHz / 512 MB.
29 If you use g++ from gcc-3.x, I recommend adding "-fno-exceptions" to the
30 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. Do not use gcc-3.0 on Sparc for compiling CLN, it
37 If you use g++ on OSF/1 or Tru64 using gcc-3.0.n with n larger than 1, you
38 should not add -fno-exceptions to the CXXFLAGS, since that will generate
39 wrong code (gcc-3.1 is okay again, as is gcc-3.0).
