This patch adds the management of (almost) all the config options of openocd 0.8.0. A BR config variable is added for (almost) every adapter known to openocd and all the dependencies are automatically calculated from the chosen adapters, so only the necessary libraries are built. Note that CMSIS_DAP adapter requires hidapi (not libhid) and hidapi is not actually included in buildroot, so it has been removed. Also zy1000 adapters are actually broken in openocd and have been removed. The host version of the package enables all the possible adapters and the related libraries. [Thomas: - Slightly fixup the commit log. - Rename the patches to the new patch naming convention. - Update hash file using a contribution from Vincent Stehlé. - Move the thread dependency from the OpenOCD option down to each sub-option that actually needs it (when it needs libusb, libusb-compat or libftdi). We keep only one comment, as we would otherwise have to add too many repeatitive comments. - Remove commented options. - Add missing dependency on BR2_ARCH_HAS_ATOMICS when selecting BR2_PACKAGE_LIBFTDI. - Remove trailing white spaces. - Pass -std=gnu99, needed to build with a basic toolchain. - Write the OPENOCD_DEPENDENCIES and OPENOCD_CONF_OPTS conditions in a more compact way. - Adjust indentation for HOST_OPENOCD_CONF_OPTS. - Reword the comment above HOST_OPENOCD_CONF_OPTS.] Signed-off-by: Claudio Laurita <claudio.laurita@integrazionetotale.it> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) Use your shiny new root filesystem. Depending on which sort of
root filesystem you selected, you may want to loop mount it,
chroot into it, nfs mount it on your target device, burn it
to flash, or whatever is appropriate for your target system.
You do not need to be root to build or run buildroot. Have fun!
Offline build:
==============
In order to do an offline-build (not connected to the net), fetch all
selected source by issuing a
$ make source
before you disconnect.
If your build-host is never connected, then you have to copy buildroot
and your toplevel .config to a machine that has an internet-connection
and issue "make source" there, then copy the content of your dl/ dir to
the build-host.
Building out-of-tree:
=====================
Buildroot supports building out of tree with a syntax similar
to the Linux kernel. To use it, add O=<directory> to the
make command line, E.G.:
$ make O=/tmp/build
And all the output files (including .config) will be located under /tmp/build.
More finegrained configuration:
===============================
You can specify a config-file for uClibc:
$ make UCLIBC_CONFIG_FILE=/my/uClibc.config
And you can specify a config-file for busybox:
$ make BUSYBOX_CONFIG_FILE=/my/busybox.config
To use a non-standard host-compiler (if you do not have 'gcc'),
make sure that the compiler is in your PATH and that the library paths are
setup properly, if your compiler is built dynamically:
$ make HOSTCC=gcc-4.3.orig HOSTCXX=gcc-4.3-mine
Depending on your configuration, there are some targets you can use to
use menuconfig of certain packages. This includes:
$ make HOSTCC=gcc-4.3 linux-menuconfig
$ make HOSTCC=gcc-4.3 uclibc-menuconfig
$ make HOSTCC=gcc-4.3 busybox-menuconfig
