|
||
HAVE_CAN_FSTACKPROTECTORALL ac_flags
|
||
|
||
==== cpp definitions ====
|
||
DEBUG dont use in production, wants gcc, implies:
|
||
DEBUG_LEAKS enable freeing resources before exiting
|
||
MKSHRC_PATH "~/.mkshrc" (do not change)
|
||
MKSH_A4PB force use of arc4random_pushb
|
||
MKSH_ASSUME_UTF8 (0=disabled, 1=enabled; default: unset)
|
||
MKSH_BINSHPOSIX if */sh or */-sh, enable set -o posix
|
||
MKSH_BINSHREDUCED if */sh or */-sh, enable set -o sh
|
||
MKSH_CLRTOEOL_STRING "\033[K"
|
||
MKSH_CLS_STRING "\033[;H\033[J"
|
||
MKSH_CONSERVATIVE_FDS fd 0-9 for scripts, shell only up to 31
|
||
MKSH_DEFAULT_EXECSHELL "/bin/sh" (do not change)
|
||
MKSH_DEFAULT_PROFILEDIR "/etc" (do not change)
|
||
MKSH_DEFAULT_TMPDIR "/tmp" (do not change)
|
||
MKSH_DISABLE_DEPRECATED disable code paths scheduled for later removal
|
||
MKSH_DISABLE_EXPERIMENTAL disable code not yet comfy for (LTS) snapshots
|
||
MKSH_DISABLE_TTY_WARNING shut up warning about ctty if OS cant be fixed
|
||
MKSH_DONT_EMIT_IDSTRING omit RCS IDs from binary
|
||
MKSH_MIDNIGHTBSD01ASH_COMPAT set -o sh: additional compatibility quirk
|
||
MKSH_NOPROSPECTOFWORK disable jobs, co-processes, etc. (do not use)
|
||
MKSH_NOPWNAM skip PAM calls, for -static on eglibc, Solaris
|
||
MKSH_NO_CMDLINE_EDITING disable command line editing code entirely
|
||
MKSH_NO_DEPRECATED_WARNING omit warning when deprecated stuff is run
|
||
MKSH_NO_EXTERNAL_CAT omit hack to skip cat builtin when flags passed
|
||
MKSH_NO_LIMITS omit ulimit code
|
||
MKSH_NO_SIGSETJMP define if sigsetjmp is broken or not available
|
||
MKSH_NO_SIGSUSPEND use sigprocmask+pause instead of sigsuspend
|
||
MKSH_SMALL omit some code, optimise hard for size (slower)
|
||
MKSH_SMALL_BUT_FAST disable some hard-for-size optim. (modern sys.)
|
||
MKSH_S_NOVI=1 disable Vi editing mode (default if MKSH_SMALL)
|
||
MKSH_TYPEDEF_SIG_ATOMIC_T define to e.g. 'int' if sig_atomic_t is missing
|
||
MKSH_TYPEDEF_SSIZE_T define to e.g. 'long' if your OS has no ssize_t
|
||
MKSH_UNEMPLOYED disable job control (but not jobs/co-processes)
|
||
|
||
=== 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 -f) 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.
