commit: https://git.buildroot.net/buildroot/commit/?id=b869760f11f148a06027e63c0d0bbccb55a217f3 branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next When building checkpolicy/test, the linker reports the following error: cc dispol.o -lfl /usr/src/selinux/DESTDIR/usr/lib/libsepol.a -L/usr/src/selinux/DESTDIR/usr/lib -o dispol /usr/lib/gcc/x86_64-pc-linux-gnu/6.2.1/../../../../lib/libfl.so: undefined reference to `yylex' collect2: error: ld returned 1 exit status According to flex documentation (https://github.com/westes/flex/blob/master/doc/flex.texi), -lfl is used to provide an implementation for yywrap(). However every flex file now uses "%option noyywrap", which makes -lfl no longer mandatory. Remove this option from checkpolicy Makefiles.
