7 prompt "Number of parallel jobs"
10 Number of jobs make will be allowed to run concurently.
11 Set this higher than the number of processors you have, but not too high.
12 A good rule of thumb is twice the number of processors you have.
14 Enter 1 (or 0) to have only one job at a time.
18 prompt "Maximum allowed load"
21 Specifies that no new jobs should be started if there are others jobs
22 running and the load average is at least this value.
24 Makes sense on SMP machines only.
26 Enter 0 to have no limit on the load average.
28 Note: only the integer part of the load is allowed here (you can't enter
36 Use gcc's option -pipe to use pipes rather than temp files when building
41 prompt "Shell to use as CONFIG_SHELL"
42 default CONFIG_SHELL_BASH
44 config CONFIG_SHELL_SH
46 prompt "sh (the system shell)"
48 Use 'sh' as CONFIG_SHELL.
50 ./configure scripts and Makefiles make intensive use of calling
51 sub-shells. This is usually done by calling /bin/sh. /bin/sh ought
52 to be an at-least-POSIX-conformant shell (that is, able to interpret
55 On many (most?) systems, /bin/sh is a symlink to bash. On some other
56 systems (eg. Ubuntu, latest Debian), /bin/sh points to dash (or ash).
57 bash is a full-featured shell, with many extension to POSIX, but is
58 quite slow (see ection BUGS in the bash man page), while dash is
59 faster, with very few extensions to POSIX. On the other hand, some
60 ./configure scripts, although written to use /bin/sh, may really
61 require to be run by bash.
63 The default is to use bash, as some components (eg. GMP) will fail
64 to build with anything else than bash.
66 config CONFIG_SHELL_ASH
68 prompt "ash (READ HELP!)"
70 Use 'ash' as CONFIG_SHELL.
72 See help for CONFIG_SHELL_SH, above, for more explanations.
74 NOTE: It is advised that you do NOT use ash as CONFIG_SHELL, as some
75 components are broken. If you decide to use ash, and the build breaks,
76 don't come moaning and set the CONFIG_SHELL to bash, below.
78 config CONFIG_SHELL_BASH
82 Use 'bash' as CONFIG_SHELL.
84 See help for CONFIG_SHELL_SH, above, for more explanations.
86 config CONFIG_SHELL_CUSTOM
90 Enter full path to the custom shell below.
92 See help for CONFIG_SHELL_SH, above, for more explanations.
94 config CONFIG_SHELL_CUSTOM_PATH
96 prompt "Path to custom shell"
97 depends on CONFIG_SHELL_CUSTOM
104 default "sh" if CONFIG_SHELL_SH
