erlang-lz4's Issues

Push latest version to Hex.pm

Hi @szktty,
Would it be possible to push 0.2.4 to hex.pm?

https://hex.pm/packages/lz4

Thanks

New tag?

Hi,

Would you please consider publishing a new tag (0.2.5?) from the version of the software in the develop branch that contains simplification of native code compilation?

Cannot compile on otp 23

> DEBUG=1 rebar3 compile
# ...
failed with return code 1 and the following output:
ld: library not found for -lerl_interface
clang: error: linker command failed with exit code 1 (use -v to see invocation)

lerl_interface is deprecated by the looks of things https://www.erlang.org/news/tag/release

Cannot compile :lz4

Security fix for 32-bits systems

Hi Tetsuya

There is a new security fix for 32-bits system available at :
https://github.com/Cyan4973/lz4/releases/latest

The issue affects programs accepting very large data blocks in 32-bits mode.

As a security measure, all binders are invited to upgrade their underlying C source code to latest version.

Regards

Hex.pm package for 0.2.4 is broken on non-OSX

The package in Hex.pm includes OSX (Mach-O) objectfiles. These files break the build on any non-OSX platform. On Linux, I see

Grabbing lz4 from github works well.
