if you can be bothered, see how much of it is the issues covered here #14 (comment)
it will most likely be a combination of a lib being too old and your weechat being too old. I could eventually check it out in vm but I suspect running into similar issues as when I did for ubuntu

[roughnecks]

I read that but honestly, I don't know: WeeChat 4.6.3 [compiled on May 17 2025 05:49:46]

I have loaded up a debian vm. in retrospect I missed an obvious part. for some reason your system does not have __progname

__progname: no

the diff dep will trip over this https://github.com/kristapsdz/libdiff/blob/aadb3d7fe4dcb4b212c77e4fc6c2599826aeb50a/compats.c#L175-L193

surprisingly enough I was not able to reproduce this part on my debian vm, nor the ubuntu vm from before. less surprisingly even besides that you run into the issues mentioned in the previous ubuntu issue later where liblmdb++ is not 1.0 but instead 0.9.14, which errors on dbi() calls later.

seeing as the ubuntu I was messing with had weechat 4.1.1, you might luck out on it after you get past those hurdles. I unfortunately do not have any quick fixes nor time to look at it right now.
you'd have to either find out why for some reason your glibc does not provide __progname or just bodge that function to return a string regardless of the compiler checks, its pretty much useless anyway only used for error logging.
then as for the ubuntu system get an up to date (1.0) lmdb++.h, and then hope the weechat is up to date enough for the other changes or roll those back.

EDIT: it will try to clean the submodule each time you run make clean, but for bodging the deps/diff/compat.c this should do, you should at least get further in compiling and to the next error

@bqv going by what you've done with #14, this is going pretty much the same way.
unless theres some unknown way to get a nice lmdb++ 1.0 on debain based distros.
their weechat version might be fine by now though

[bqv]

I really didn't want to bundle lmdb++, but if its the best solution here it may as well be done... Likewise the diff dep (last commit 8y ago, should probably just take ownership if distros keep breaking builds)

Open to build system patches, at least

[Ckath]

@roughnecks the __progname part has been fixed now, at worst you should now run into the lmdb++. your weechat is probably fine version wise
