2 # MACHINE -- operating system specific information
5 nmh is known to compile on the following platforms (save the
6 exceptions noted below), using an ANSI C compiler, such as gcc.
9 Cygwin, setup version 2.763 (though it does not run correctly, see below)
12 Linux 2.2 to current (glibc 2.1 to current)
16 Solaris 7 and 8 (sparc,x86)
19 Known Compilation problems:
20 --------------------------------------
25 Some BSD4.4 machines have problems when running nmh's configure script.
26 They will be unable to find the location of vi and sendmail. This is
27 due to POSIX features (breakage?) in the shell sh. The solution is to
28 run the configure script under the shell `bash':
32 --------------------------------------
35 Version 5.3 at least has the same sh/bash bug as the *BSD systems
36 above. This appears to be fixed in 5.5.
38 Will not compile correctly unless you configure with the --enable-debug
39 option. It appears to find conflicts in the headers only when debugging
40 is disabled. With debugging enabled, it compiles and runs happily.
42 --------------------------------------
45 Be sure to install Cygwin package libncurses-devel, in the Devel or
46 Libs category. And libncurses10 or later in the Lib category.
48 Which nmh builds on Cygwin, not all of its programs operate. If
49 you're willing to help fix them, please contact the nmh maintainters
50 at nmh-workers@nongnu.org.
52 --------------------------------------
55 Lots of problems have been reported with using HPUX `cc'. In particular,
56 problems with `scan' giving incorrect dates (everything is 01/00).
57 It is highly recommended that you use `gcc' instead.
59 Also, new versions of HPUX (10.20?) will core dump in `scan' because
60 of some workaround code in zotnet/tws/lexstring.c. This workaround is
61 needed for older versions of HPUX, but causes problems on newer versions.
62 The solution is the added line (minus our indentation):
66 after line 15 of the file zotnet/tws/lexstring.c.
68 --------------------------------------
71 Irix make is notoriously buggy. If you're using it, you should "touch
72 config.h.in" before configuring to prevent a problem where it tries to
73 rebuild targets that shouldn't be rebuilt. (Alternately, you can just
74 use GNU make instead of Irix make.)
76 --------------------------------------
79 The configuration script does a test to discover if your vi is broken
80 (if it reports non-zero exit codes on certain pseudo-errors). This test
81 will hang if the program `ex' on your system is a link to the vi clone
82 `vile'. The workaround is to replace the command ex as a link to another
83 vi clone such as nvi or elvis.
85 --------------------------------------
88 With --enable-debug you'll see a lot of warnings. This is even worse
89 when compiling using the Sun Workshop compiler since it issues a
90 warning for every instance of a problem instead of summarizing them.
91 The main one concerns arrays with an index of type char. This is ok.
92 The array itself is a hash of chars, so the array size and the type
93 match. There isn't another safe and portable way to do this at the
94 moment. An explicit cast would get rid of the warnings, but I think
95 it's better to leave it complaining for now until we come up with
96 a better solution. The whole thing is probablly going to be chucked
97 with UTF-8 support anyway.
99 Other than the warnings, it builds ok.
100 --------------------------------------
101 SunOS 4.1.1/4.1.3/4.1.4:
103 You can't use the C compiler that comes with SunOS 4 since
104 it isn't ANSI C. But nmh builds just fine with gcc. With
105 --enable-debug you will see a lot of warnings.
