Installation of efivar
![[Note]](../images/note.png)
Note
This package cannot function properly on a 32-bit system with a 64-bit UEFI implementation. Don't install this package (or efibootmgr) on 32-bit system unless you are absolutely sure you have a 32-bit UEFI implementation, which is very rare in practice.
Build efivar with the following commands:
make ENABLE_DOCS=0
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, Install by running this command:
make install ENABLE_DOCS=0 LIBDIR=/usr/lib
To avoid a hard dependency on mandoc we used
ENABLE_DOCS=0, but it causes all the man pages
skipped from the installation even though most of them actually
do not need mandoc. Still as the root user,
install these man pages:
install -vm644 docs/efivar.1 /usr/share/man/man1 install -vm644 docs/*.3 /usr/share/man/man3
Command Explanations
ENABLE_DOCS=0: Disable the generation of man
pages, in order to allow building this package without
mandoc installed.
LIBDIR=/usr/lib:
This option overrides the default library directory of the package
(/usr/lib64, which is not used
by LFS).
