BUG?: "zstd 1.5.5 library detected but is lower than bundled version (1.5.2)"

[HenrikBengtsson]

When I build qs2 0.1.6 in R 4.5.2 on Ubuntu 24.04 LTS, I get:

zstd 1.5.5 library detected but is lower than bundled version (1.5.2) -- compiling from source

That looks like a mistake - the version of "zstd 1.5.5" is newer than the "bundled version (1.5.2)".

Hi Henrik, thanks for pointing that out. The bundled version is actually 1.5.6 and I forgot to update the message. So the issue is the message not the check.

I just pushed an update to CRAN but I'll fix the message in the next version.

Bundled version in header file:

qs2/src/ZSTD/zstd.h

Line 109 in 1937036

#define ZSTD_VERSION_RELEASE 6
