Since Linux 3.10, perf's NO_NEWT configuration option simply sets NO_SLANG=1 and there is no dependency on libnewt. We already handle NO_SLANG correctly based on whether or not BR2_PACKAGE_SLANG is selected, so all we accomplish by setting NO_NEWT=1 is disabling perf's TUI when all of the dependencies are available. To simplify all of this, introduce a new config option to enable the perf TUI which depends on slang and add a check to prevent building the TUI on versions which are too old. The check for NO_SLANG is equivalent to checking if NO_NEWT is required as NO_SLANG was added in the same commit that removed the libnewt dependency and deprecated NO_NEWT (6692c262df4f, "perf tools: Remove dependency on libnewt", 2013-03-28).

Morin.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> |

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
