First, apply a patch to fix an issue building with GCC 9 or later:
patch -Np1 -i ../efivar-37-gcc_9-1.patch
Build efivar with the following commands:
make CFLAGS="-O2 -Wno-stringop-truncation"
The test suite of this package is dangerous. Running it may trigger firmware bugs and make your system unusable without using some special hardware to reprogram the firmware.
Now, as the root user:
make install LIBDIR=/usr/lib BINDIR=/bin
Move the shared libraries to /lib,
and recreate the symlinks in /usr/lib:
mv /usr/lib/libefi{boot,var}.so.* /lib &&
ln -sfv ../../lib/$(readlink /usr/lib/libefiboot.so) /usr/lib/libefiboot.so &&
ln -sfv ../../lib/$(readlink /usr/lib/libefivar.so) /usr/lib/libefivar.so
CFLAGS="-O2
-Wno-stringop-truncation": This option overrides the
default compiler flags to avoid a build failure.
LIBDIR=/usr/lib: This
option overrides the default library directory of the package
(/usr/lib64, which is not used by
LFS.)
BINDIR=/bin: Make
efivar avaliable even
if /usr is offline.
