config EXPERIMENTAL

    bool

    prompt "Try features marked as EXPERIMENTAL"

    default n

    help

      If you set this to Y, then you will be able to try very experimental

      features.

      Experimental features can be one of:

        - working, in which case you should tell me it is!

        - buggy, in which case you could try patching and send me the result

        - unfinished, in which case you could try hacking it and send me the result

        - non-existant, in which case you could also try hacking it in and send the result

config OBSOLETE

    bool

    prompt "Use obsolete features"

    default n

    help

      If you set this to Y, you will be able to select obsolete features.

      Such obsolete features are the use of old kernel headers, old

      gcc versions, etc...

config PARALLEL_JOBS

    int

    prompt "Number of parallel jobs"

    default 1

    help

      Number of jobs make will be allowed to run concurently.

      Set this higher than the number of processors you have, but not too high.

      A good rule of thumb is twice the number of processors you have.

      Enter 1 (or 0) to have only one job at a time.

config LOAD

    int

    prompt "Maximum allowed load"

    default 0

    help

      Specifies that no new jobs should be started if there are others jobs

      running and the load average is at least this value.

      Makes sense on SMP machines only.

      Enter 0 to have no limit on the load average.

      Note: only the integer part of the load is allowed here (you can't enter

            0.75 for example).

config NICE

    int

    prompt "Nice level"

    default 0

    range 0 19

    help

      Renices the build process up.

config USE_PIPES

    bool

    prompt "Use -pipe"

    default y

    help

      Use gcc's option -pipe to use pipes rather than temp files when building

      the toolchain.

comment "Paths"

config TARBALLS_DIR

    string

    prompt "Tarballs directory"

    default "${CT_TOP_DIR}/build/tarballs"

    help

      This is the directory into which tarballs are going to be stored once

      they are downloaded (or otherwise retrieved).

config SRC_DIR

    string

    prompt "Extract directory"

    default "${CT_TOP_DIR}/build/${CT_TARGET}/${CT_CC}-${CT_CC_VERSION}-${CT_LIBC}-${CT_LIBC_VERSION}/src"

    help

      This is the directory into which tarballs will be extracted.

      If you will build multiple toolchains, you should arrange to have one

      SRC_DIR for each toolchain, as different targets may require different

      patches to be applied.

      You should not need to change this from the default.

config BUILD_DIR

    string

    prompt "Build directory"

    default "${CT_TOP_DIR}/build/${CT_TARGET}/${CT_CC}-${CT_CC_VERSION}-${CT_LIBC}-${CT_LIBC_VERSION}/build"

    help

      This is the directory into which builds will occur.

      Once again, arrange for one build directory for each toolchain you build,

      to avoid collision.

      You should not need to change this from the default.

config PREFIX_DIR

    string

    prompt "Prefix directory"

    default "${HOME}/${CT_TARGET}"

    help

      This is the path the toolchain will run from.

config INSTALL_DIR

    string

#    prompt "Install directory"

    default "${CT_PREFIX_DIR}"

#    help

#      This is the path the target will be installed into.

#      

#      Normally, you would set this to ${CT_PREFIX_DIR}, but if for some reasons

#      you can't write there, you can install somewhere else and have a third

#      person do the install for you.

#      The reason you might also want to install elsewhere is if you are going

#      to package your shinny new toolchain for distribution.

config CUSTOM_PATCH

    bool

    prompt "Use custom patch directory"

    default n

    help

      If you have custom patches that you want to be applied, say 'Y' here and

      enter the path directory below.

      Note that you must ensure that the patch directory is arranged the same

      way the official directory is.

config CUSTOM_PATCH_ONLY

    bool

    prompt "Only use custom patches"

    default n

    depends on CUSTOM_PATCH

    help

      Don't apply patches coming with CT-NG, only those patches available in

      the directory below.

      If you say 'N' here, then the patches provided with CT-NG will be applied

      first, and then your patches.

config CUSTOM_PATCH_DIR

    string

    prompt "Custom patch directory"

    default ""

    depends on CUSTOM_PATCH

    help

      Enter the custom patch directory here.

      Usefull if you suspect a previous extract did not complete (eg. broken

      If you say Y here, then you will have see the warning lines from

      to extract the configuration of crosstool-NG from the log file.

      Definitely, say Y.
