交叉编译e2fsprogs，配置了：
../configure –host=arm-linux –prefix=/home/crifan/rootfs-2007/root/usr –exec-prefix=/home/crifan/rootfs-2007/root/usr –includedir=/root/buildroot/buildroot/build_arm/staging_dir/usr/include –libdir=/root/buildroot/buildroot/build_arm/staging_dir/lib –enable-fsck –with-cc=/root/buildroot/buildroot/build_arm/staging_dir/usr/bin/arm-linux-uclibc-gcc
然后make，在ld的时候出现错误：
LD tst_uuid

/home/crifan/tmp/e2fsprogs-1.41.3/build/lib/uuid/../../../lib/uuid/gen_uuid.c:153: undefined reference to `__aeabi_read_tp’

【解决办法】
google了下，说是：
http://lists.cross-lfs.org/pipermail/clfs-support-cross-lfs.org/2009-June/000628.html
“Yes, you need to disable threading for e2fsprogs when you’re using
uClibc. I believe the option is –disable-tls.”
即，交叉编译，用的uClibc的话，要禁用tls，去
configure –help里面能找到此选项的说明：
–disable-tls disable use of thread local support
所以，在配置的时候，加上参数–disable-tls即可：
../configure –host=arm-linux –prefix=/home/crifan/rootfs-2007/root/usr –exec-prefix=/home/crifan/rootfs-2007/root/usr –includedir=/root/buildroot/buildroot/build_arm/staging_dir/usr/include –libdir=/root/buildroot/buildroot/build_arm/staging_dir/lib –enable-fsck –with-cc=/root/buildroot/buildroot/build_arm/staging_dir/usr/bin/arm-linux-uclibc-gcc –disable-tls
然后make就可以顺利编译过了，然后make check 后，make install即可。
