I have the linux utils code (can be found here: https://www.kernel.org/pub/linux/utils/util-linux/) and I only need libuuid, nothing else. I’ve tried setting many ‘–disable-‘ flags but it still seems to be compiling things I don’t need.
Here’s my actual configure command:
./configure --disable-libblkid --disable-libmount --disable-mount --disable-losetup --disable-cytune --disable-fsck --disable-partx --disable-uuidd --disable-mountpoint --disable-fallocate --disable-unshare --disable-nsenter --disable-setpriv --disable-eject --disable-agetty --disable-cramfs --disable-bfs --disable-fdformat --disable-hwclock --disable-wdctl --disable-switch_root --disable-pivot_root --disable-kill --disable-last --disable-utmpdump --disable-mesg --disable-raw --disable-rename --disable-login --disable-nologin --disable-sulogin --disable-su --disable-runuser --disable-ul --disable-more --disable-pg --disable-setterm --disable-schedutils --disable-wall --build="$BUILD_ARCH" --host="$HOST_ARCH" --prefix="$outputdir" --exec-prefix="$outputdir"
and here’s my output:
<...build things including libuuid...> CC fdisks/cfdisk-cfdisk.o ../fdisks/cfdisk.c: In function 'get_string': ../fdisks/cfdisk.c:447:5: warning: implicit declaration of function 'getyx' [-Wimplicit-function-declaration] ../fdisks/cfdisk.c:447:5: warning: nested extern declaration of 'getyx' [-Wnested-externs] ../fdisks/cfdisk.c:447:11: error: 'stdscr' undeclared (first use in this function) <...>
Is there any way to only build libuuid?

Answer
The easiest approach would be to pull the latest linux-utils tarball from the link you provided, extract it’s contents, and then modify the root-level Makefile.am. Look for the section that looks like this:
include tools/Makemodule.am include include/Makemodule.am include lib/Makemodule.am include libuuid/Makemodule.am include libblkid/Makemodule.am include libmount/Makemodule.am include libsmartcols/Makemodule.am include libfdisk/Makemodule.am include schedutils/Makemodule.am include text-utils/Makemodule.am include term-utils/Makemodule.am include login-utils/Makemodule.am include sys-utils/Makemodule.am include misc-utils/Makemodule.am include disk-utils/Makemodule.am include bash-completion/Makemodule.am include tests/Makemodule.am
And modify it to look like so (leave only the libuuid entry uncommented):
#include tools/Makemodule.am #include include/Makemodule.am #include lib/Makemodule.am include libuuid/Makemodule.am #include libblkid/Makemodule.am #include libmount/Makemodule.am #include libsmartcols/Makemodule.am #include libfdisk/Makemodule.am # #include schedutils/Makemodule.am #include text-utils/Makemodule.am #include term-utils/Makemodule.am #include login-utils/Makemodule.am #include sys-utils/Makemodule.am #include misc-utils/Makemodule.am #include disk-utils/Makemodule.am # #include bash-completion/Makemodule.am # #include tests/Makemodule.am
Finally, from the root directory (of the archive you extracted), execute the following:
autoconf automake ./configure make
You may need to run automake --add-missing instead of automake, and autoreconf --force --install instead of autoconf, depending on the version of autotools installed on your system.
Now, just find your built library via find . -iname "*libuuid.so*".
