Ubuntu 14.04编译squashfs3.2-r2时出错
1./usr/bin/ld: mksquashfs.o: undefined reference to symbol ‘log10@@GLIBC_2.0’
/usr/bin/ld: note: ‘log10@@GLIBC_2.0’ is defined in DSO /lib/libm.so.6 so try andding it to the linker command line
/lib/libm.so.6: could not read symbols: Invalid operation
找到“squashfs3.2-r2/squashfs-tools”目录下Makefile文件
修改：mksquashfs: LDLIBS += -lpthread -lunlzma_r -llzma_r -lstdc++
成：mksquashfs: LDLIBS += -lpthread -lunlzma_r -llzma_r -lstdc++ -lm

在mksquash_lzma-3.2/squashfs3.2-r2/squashfs-tools/Makefileunsquashfs: LDLIBS += -lunlzma後面加上–lz可解決
