#1235977 — Bug#1099464: lz4: `lz4c` Softlink Missing

Package: lz4
Version: 1.10.0-3
Severity: normal

Dear Maintainer,

	The softlink /usr/bin/lz4c -> /usr/bin/lz4 is no longer present.
Some utilities -- notably the Yocto build system -- assume it's present,
and will abort almost immediately if it's not.

	This softlink disappeared with the new upstream release from 1.9.x to
1.10.0.  Neither the Debian changelog nor upstream's release notes make
any mention of this change, which makes it a little puzzling.

#1236517

Hi Leo,

Thank you for letting me know.
I switched the build tool from autotools to CMake, and CMake had lz4c
setting removed.
This is the cause. I will fix this.

Best regards,
  Nobuhiro
