unrar 6.2.6 build error w/ rar2fs1.29.6

[KyleSanderson]

6.2.5 seems to be the last version that builds.

Is this a report of build problems with rar2fs or unrarsrc? Looks like the latter to me. In fact, I cannot seem to build any 6.2.x versions, the last working buildable version for me is 6.1.8. So something have changed in unrarsrc from RARLabs that requires a more recent C++ compiler?

[tfiskgul]

On Gentoo, unrar-6.2.3 and rar2fs-1.29.5 builds fine with gcc-12.2.1

[hasse69]

I am on a much older version of gcc/g++ and currently don't have the possibility to upgrade, which means this is going to be difficult for me to investigate right now.

[hasse69]

Luckily I could find a host for which I was able to install gcc-12.1.0. For me it works just fine to build unrarsrc-6.2.6 in combination with latest version of rar2fs.

[KyleSanderson]

Yeah, it's unrarsrc with the issue it seems like.

I highly recommend buildah if you can swing it, then you can remove the artifacts out if that's your preference.

[hasse69]

Not sure what you mean really. The unrarsrc is a completely separate buildable package but rar2fs requires access to some of its private source files (headers).

[hasse69]

Can this issue be closed?

[KyleSanderson]

Yes it can.
