Since948666dfde, librtlsdr in Buildroot is no longer built from an official release, but from a commit on the master branch. However, the commit that was referenced has a broken pkgconfig file templating, such that other packages using `pkgconfig --libs librtlsdr` as part of their build process (such as dump1090) could not be built anymore: Before948666dfde: $ cat staging/usr/lib/pkgconfig/librtlsdr.pc prefix=/usr exec_prefix=${prefix} libdir=${exec_prefix}/lib includedir=${prefix}/include Name: RTL-SDR Library Description: C Utility Library Version: 0.6.0 Cflags: -I${includedir}/ Libs: -L${libdir} -lrtlsdr -lusb-1.0 Libs.private: On948666dfde: $ cat staging/usr/lib/pkgconfig/librtlsdr.pc prefix= exec_prefix= libdir= includedir= Name: RTL-SDR Library Description: C Utility Library Version: 7082 Cflags: -I${includedir}/ Libs: -L${libdir} -lrtlsdr Libs.private: -lusb-1.0 In the meantime, upstream released a bugfix for that ([1]), so we bump to that commit as well, and update the only patch for shared libs accordingly, because upstream also added a new tool called `rtl_biast` in the meantime. Finaly, we update the hash file to the two-spaces convention.

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.
