| Enter the base name of the sysroot directory. Usually, this simply |
| is 'sysroot' (the default) or 'sys-root'. |
| |
| You are free to enter anything here, except for spaces, and '/' |
| (see SYSROOT_DIR_PREFIX, below). If you leave this empty, then the |

| Build static host binaries. |
| |
| If you wish to move the toolchain to another host, and you are not |
| confident that this host has the required versions of system libs, then |
| you can say 'Y' here, and all the host tools will be linked statically. |
| |
| The impacted tools are: |
| - the cross-binutils (GNU binutils, elf2flt) |
| - the cross-compiler (gcc) |
| - the cross-debugger (gdb) |
| |
| The default is 'N', to build dynamicaly-linked host binaries. |
| |
| NOTE: this has no connection to whether the target libraries will be |
| dynamic or static. This only applies to the tools themselves. |

| config TOOLCHAIN_PKGVERSION |
| string |
| prompt "Toolchain ID string" |
| default "" |
| help |
| Specify a string that identifies your package. You may wish to include |
| a build number or build date. This version string will be included in |
| the output of gcc --version, and also in binutils, eglibc, gdb and |
| gdbserver. |
| |
| If this string is left empty, the actual package version will be: |
| "crosstool-NG ${CT_VERSION}" |
| Otherwise, it will be: |
| "crosstool-NG ${CT_VERSION} - ${CT_TOOLCHAIN_PKGVERSION}" |

| Vendor part of the target tuple. |
| |
| A tuple is of the form arch-vendor-kernel-system. |
| You can set the second part, vendor, to whatever you see fit. |
| Use a single word, or use underscores "_" to separate words. |
| Use neither dash nor space, as it breaks things. |
| |
| Keep the default (unknown) if you don't know better. |
| |
| config TARGET_ALIAS_SED_EXPR |
| string |
| prompt "Tuple's sed transform" |
| default "" |
| help |
| Normally, you'd call your toolchain components (especially gcc) by |
| prefixing the target tuple followed by a dash and the component name |
| (eg. armeb-unknown-linux-uclibc-gcc). |
| |
| You can enter here a sed expression to be applied to ${CT_TARGET} to |
| create an alias for your toolchain. |
| |
| For example, "s/${CT_TARGET_VENDOR}/foobar/" (without the double quotes) |
| will create the armeb-foobar-linux-uclibc alias to the above-mentioned |
| toolchain. |
| |
| You shouldn't need to enter anything here, unless you plan to manually |
| call the tools (autotools-based ./configure will use the standard name). |

| Normally, you'd call your toolchain components (especially gcc) by |
| prefixing the target tuple followed by a dash and the component name |
| (eg. armeb-unknown-linux-uclibc-gcc). |
| |
| You can enter a shortcut here. This string will be used to create |
| symbolic links to the toolchain tools (eg. if you enter "foo-bar" here, |
| then gcc for your toolchain will also be available as "foo-bar-gcc" along |
| with the original name). |
| |
