解決：

1.downlod xz-5.0.3.tar.bz2

2. 解壓縮：#tar jxvf xz-5.0.3.tar.bz2

3. #cd xz-5.0.3

4. #make

5. copy liblzma.so.5.0.3 至 /opt/buildroot-gcc342/lib

6.#cd  /opt/buildroot-gcc342/lib

7.#ln -s lib liblzma.so.5.0.3  liblzma.so

8.#ln -s lib liblzma.so.5.0.3  liblzma.so.0

問題2. liblzma.so.0: wrong ELF class: ELFCLASS64

解決：重新編譯 squashfs4.2.tar.gz

1. download squashfs4.2.tar.gz

2. #tar zxvf   squashfs4.2.tar.gz

3. #cd  squashfs4.2/squashfs-tools

4. #vi Makefile (問題3 需要修改)

 GZIP_SUPPORT = 1

 19 

 20 ########### Building XZ support #############

 21 #

 22 # LZMA2 compression.

 23 #

 24 # XZ Utils liblzma (http://tukaani.org/xz/) is supported

 25 #

 26 # To build using XZ Utils liblzma - install the library and uncomment

 27 # the XZ_SUPPORT line below.

 28 #

 29 XZ_SUPPORT = 1

5.#make

6.將編譯好的mksquashfs 取代舊的

#cp mksquashfs  /opt/buildroot-gcc342/bin/mksquashfs_lzma-4.2

問題3 mksquashfs compressor xz is not supported
