This was fixed ~6 years ago per bug 371129, but it seems that the fix has been lost in time. https://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-apps/busybox/busybox-1.18.4.ebuild?hideattic=0&view=markup Alternatively, is it possible that FEATURE_MOUNT_NFS is entirely obsolete, and can be hard-disabled when importing savedconfig? The help text is unclear if it's actually needed at all in newer kernels. Probably fix it BOTH ways: - Always disable FEATURE_MOUNT_NFS (provide some way for people who might be building for an ancient kernel to keep it?). - Include libtirpc cflags via pkgconfig. This would let anybody who also uses FEATURE_INETD_RPC keep compiling as well. make -f scripts/Makefile.build obj=sysklogd make -f scripts/Makefile.build obj=util-linux make -f scripts/Makefile.build obj=util-linux/volume_id x86_64-pc-linux-gnu-gcc -Wp,-MD,util-linux/.mount.o.d -std=gnu99 -Iinclude -Ilibbb -include include/autoconf.h -D_GNU_SOURCE -DNDEBUG -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -D"BB_VER=KBUILD_STR(1.27.2)" -DBB_BT=AUTOCONF_TIMESTAMP -march=native -O2 -pipe -fno-strict-aliasing -Wall -Wshadow -Wwrite-strings -Wundef -Wstrict-prototypes -Wunused -Wunused-parameter -Wunused-function -Wunused-value -Wmissing-prototypes -Wmissing-declarations -Wno-format-security -Wdeclaration-after-statement -Wold-style-definition -fno-builtin-strlen -finline-limit=0 -ffunction-sections -fdata-sections -fno-guess-branch-probability -funsigned-char -fno-unwind-tables -fno-asynchronous-unwind-tables -fno-builtin-printf -D"KBUILD_STR(s)=#s" -D"KBUILD_BASENAME=KBUILD_STR(mount)" -D"KBUILD_MODNAME=KBUILD_STR(mount)" -c -o util-linux/mount.o util-linux/mount.c util-linux/mount.c:252:22: fatal error: rpc/rpc.h: No such file or directory # include <rpc/rpc.h> ^ compilation terminated. make[1]: *** [scripts/Makefile.build:197: util-linux/mount.o] Error 1 make: *** [Makefile:742: util-linux] Error 2 * ERROR: sys-apps/busybox-1.27.2::gentoo failed (compile phase): * emake failed * * If you need support, post the output of `emerge --info '=sys-apps/busybox-1.27.2::gentoo'`, * the complete build log and the output of `emerge -pqv '=sys-apps/busybox-1.27.2::gentoo'`. * The complete build log is located at '/dev/shm/portage/sys-apps/busybox-1.27.2/temp/build.log'. * The ebuild environment file is located at '/dev/shm/portage/sys-apps/busybox-1.27.2/temp/environment'. * Working directory: '/dev/shm/portage/sys-apps/busybox-1.27.2/work/busybox-1.27.2' * S: '/dev/shm/portage/sys-apps/busybox-1.27.2/work/busybox-1.27.2'
Same for me here : if I disable FNS in config file, it builds fine.
nfs mount works now without libtirpc (I've disabled libtirpc features in the latest busybox)
