Binwalk_easybuild

本项的目标是解决在较新的Linux发行版（例如 Debian 12）上安装binwalk的依赖（例如 sasquatch）时报错的问题。

第一个错误类似下面这样:

cc -g -O2  -I. -I./LZMA/lzma465/C -I./LZMA/lzmalt -I./LZMA/lzmadaptive/C/7zip/Compress/LZMA_Lib -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_GNU_SOURCE -DCOMP_DEFAULT=\"gzip\" -Wall -Werror  -DGZIP_SUPPORT -DLZMA_SUPPORT -DXZ_SUPPORT -DLZO_SUPPORT -DXATTR_SUPPORT -DXATTR_DEFAULT   -c -o unsquashfs.o unsquashfs.c

      |     ^~
unsquashfs.c:1841:9: note: ...this statement, but the latter is misleadingly indented as if it were guarded by the ‘if’

      |         ^~~~~~~~~~~~~

make: *** [<builtin>: unsquashfs.o] Error 1

关于这个问题，在这里有讨论很多解决方案。但是我认为，问题的本质是编译时使用了-Wall选项，将所有的警告都转为了错误，导致编译中断。所以，我的解决方案是去掉-Wall选项。

第二个错误类似下面这样：

g++ -O3 -Wall -c  -I ../../../ ZLib.cpp

                 from ZLib.cpp:53:

  160 |   return __m_RefCount; delete this; return 0; }

这个问题与第一个问题一样，也是通过去掉-Wall选项解决。

第三个错误类似下面这样：

这个问题在这里有解释和解决方案，我这里采用了@mzpqnxow的方法。
