I have tested with genkernel-4.2.6-r{2,3,4} and with the live ebuild. The precise thing that fails for me is libxcrypt, during the building of the initramfs, giving errors such as: ----------- libtool: compile: x86_64-gentoo-linux-musl-gcc -DHAVE_CONFIG_H -I. -I./lib -DIN_LIBCRYPT -Wall -Wextra -Walloc-zero -Walloca -Wbad-function-cast -Wcast-align -Wcast-qual -Wconversion -Wformat=2 -Wformat-overflow=2 -Wformat-signedness -Wformat-truncation=1 -Wlogical-op -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wnull-dereference -Wold-style-definition -Wpointer-arith -Wrestrict -Wshadow -Wstrict-overflow=2 -Wstrict-prototypes -Wundef -Wvla -Wwrite-strings -Wpedantic -Werror -fno-plt -Os -pipe -fomit-frame-pointer -c lib/alg-md5.c -fPIC -DPIC -o lib/.libs/libcrypt_la-alg-md5.o In file included from lib/crypt-port.h:41, from lib/alg-md5.c:38: /usr/include/sys/cdefs.h:4:2: error: #warning usage of non-standard #include <sys/cdefs.h> is deprecated [-Werror=cpp] 4 | #warning usage of non-standard #include <sys/cdefs.h> is deprecated | ^~~~~~~ ----------- As a small side-note about the error, it is the same that I get when trying to emerge libxcrypt with the clang tool-chain, however, in genkernel's case the error persists even if I go back to using gcc.
