需要安裝的依賴項有zlib-devel、xz-devel.x86_64
修改Makefile文件以支持xz壓縮的squashfs文件，去掉Makefile中 #XZ_SUPPORT = 1的#號
yum install -y zlib-devel xz-devel.x86_64 tar xzvf squashfs4.3.tar.gz cd squashfs4.3/squashfs-tools sed -i 's/#XZ_SUPPORT/XZ_SUPPORT/g' Makefile make && make install
如果沒有安裝zlib-devel會報錯，提示
“...error: ‘Z_OK’ undeclared (first use in this function)...”
如果沒有安裝xz-devel.x86_64make&&make install不會報錯，不過嘗試解壓xz壓縮的文件會報錯，提示
...‘LZMA_OK’ undeclared (first use in this function)...
