Details on this package are located in Section 8.60.2, “Contents of Diffutils.”
The Diffutils package contains programs that show the differences between files or directories.
Prepare Diffutils for compilation:
./configure --prefix=/usr \
--host=$LFS_TGT \
gl_cv_func_strcasecmp_works=y \
--build=$(./build-aux/config.guess)
The meaning of the configure options:
gl_cv_func_strcasecmp_works=y
This option specify the result of a check for the
strcasecmp. The check requires
running a compiled C program, and this is impossible during
cross-compilation because in general a cross-compiled program
cannot run on the host distro. Normally for such a check the
configure
script would use a fall-back value for cross-compilation, but
the fall-back value for this check is absent and the
configure
script would have no value to use and error out. The upstream
has already fixed the issue, but to apply the fix we'd need
to run autoconf
that the host distro may lack. So we just specify the check
result (y as we know the
strcasecmp function in
Glibc-2.41 works fine) instead, then configure will just use the
specified value and skip the check.
Compile the package:
make
Install the package:
make DESTDIR=$LFS install
