fftw's library name depends on the precision option. Consequently, it's possible to install multiple flavor on the same target. This patch breaks fftw long double precision into a new package and: - makes BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE select BR2_PACKAGE_FFTW_LONG_DOUBLE to keep compatibility with packages that use BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE. This option will be removed in a follow-up commit; - makes fftw depend on fftw-long-double when this package is enabled. Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com> [Yann/Thomas: - Force --disable-long-double in FFTW_CONF_OPTS, just for the sake of clarity (fftw is no longer going to build the long double variant) - Use FFTW_LONG_DOUBLE_DL_SUBDIR to avoid downloading fftw multiple times - Minor reformatting tweaks in fftw-long-double.mk - Do not deprecate BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE and instead make it select BR2_PACKAGE_FFTW_LONG_DOUBLE, so that packages using BR2_PACKAGE_FFTW_PRECISION_LONG_DOUBLE continue to work.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Tested-by: "Yann E.

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
