From b1183b6dca3e0d59ce8fa81767def6ea6188e8ec Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 9 May 2020 16:39:15 +0900 Subject: bpfilter: check if $(CC) can link static libc in Kconfig On Fedora, linking static glibc requires the glibc-static RPM package, which is not part of the glibc-devel package. CONFIG_CC_CAN_LINK does not check the capability of static linking, so you can enable CONFIG_BPFILTER_UMH, then fail to build: HOSTLD net/bpfilter/bpfilter_umh /usr/bin/ld: cannot find -lc collect2: error: ld returned 1 exit status Add CONFIG_CC_CAN_LINK_STATIC, and make CONFIG_BPFILTER_UMH depend on it.
