=== generic installation instructions ===
|
||
|
||
Set CC and possibly CFLAGS, CPPFLAGS, LDFLAGS, LIBS. If cross-compiling,
|
||
also set TARGET_OS. To disable tests, set e.g. HAVE_STRLCPY=0; to enable
|
||
them, set to a value other than 0 or 1. Ensure /bin/ed is installed. For
|
||
MKSH_SMALL but with Vi mode, add -DMKSH_S_NOVI=0 to CPPFLAGS as well.
|
||
|
||
Normally, the following command is what you want to run, then:
|
||
$ (sh Build.sh -r -c lto && ./test.sh -v) 2>&1 | tee log
|
||
|
||
Copy dot.mkshrc to /etc/skel/.mkshrc; install mksh into $prefix/bin; or
|
||
/bin; install the manpage, if omitting the -r flag a catmanpage is made
|
||
using $NROFF. Consider using a forward script as /etc/skel/.mkshrc like
|
||
https://www.mirbsd.org/cvs.cgi/contrib/hosted/tg/deb/mksh/debian/.mkshrc?rev=HEAD
|
||
and put dot.mkshrc as /etc/mkshrc so users need not keep up their HOME.
