# Overall toolchain configuration: paths, jobs, etc...

menu "Paths and misc options"

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 "`pwd`/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 "`pwd`/${CT_TARGET}/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.

config BUILD_DIR
    string
    prompt "Build directory"
    default "`pwd`/${CT_TARGET}/gcc-${CT_CC_VERSION}-${CT_LIBC}-${CT_LIBC_VERSION}"
    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.

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.

config REMOVE_DOCS
    bool
    prompt "Remove documentation"
    default n
    help
      Remove the installed documentation (man and info pages).
      Gains around 8MiB for a uClibc-based, C and C++ compiler.

comment "Downloading and extracting"

config NO_DOWNLOAD
    bool
    prompt "Avoid downloads"
    default n
    help

config ONLY_DOWNLOAD
    bool
    prompt "Only download tarballs"
    default n
    depends on ! NO_DOWNLOAD
    help
      Only download the tarballs. Exit once it done.
      
      Usefull to pre-retrieve the tarballs before going off-line.

config FORCE_DOWNLOAD
    bool
    prompt "Force downloads"
    default n
    depends on ! NO_DOWNLOAD
    help
      Force downloading tarballs, even if one already exists.
      Usefull if you suspect a tarball to be damaged.

config FORCE_EXTRACT
    bool
    prompt "Force extractions"
    depends on ! ONLY_DOWNLOAD
    default n
    help
      Force extraction of already exctracted tarballs.
      
      Usefull if you suspect a previous extract did not complete (eg. broken
      tarball), or you added a new set of patches for this component.

    default LOG_INFO
