Unknown file format name raw

[RoccoMathijn]

Hi!

I'm working on an Apple M2. I have snappy 1.1.10 and snzip 1.0.5 installed via Homebrew,
When I try to run a command using raw format I get an error. For example:

λ ~ snzip -t raw
Unknown file format name raw

Readme says The raw format support is enabled only when snzip is compiled for snappy 1.1.3 or upper. so I tried to compile from source but also then it's not working.

λ ~/Downloads/snzip-1.0.5 ./configure --with-snappy=/opt/homebrew/Cellar/snappy/1.1.10`
...
checking snappy::Uncompress(snappy::Source*, snappy::Sink*)... no
configure: WARNING: raw format is not supported with this snappy version.
...

Any ideas?

Could you post config.log to gist?
It is created in the current directory when configure runs.

Could you run the configure with CXXFLAGS=-std=c++11?

$ ./configure CXXFLAGS=-std=c++11

In config.log:

configure:5688: checking snappy::Uncompress(snappy::Source*, snappy::Sink*)
configure:5701: g++ -o conftest -g -O2 -Wall -I/opt/homebrew/Cellar/snappy/1.1.10/include   -L/opt/homebrew/Cellar/snappy/1.1.10/lib conftest.cpp -lsnappy  >&5

  static constexpr int kBlockLog = 16;
         ^

constexpr requires C++11 or later.

Yes now it works!

For my understanding: Is this a bug in the Homebrew formula? Should that flag be set there?
