[SOLVED] libc++ update

Hello again,
I recently updated my Fedora to 28 and now I'm having trouble compiling Xonotic; the issue is that Fedora 28 uses a newer libc++ (8 instead of 7) but Xonotic requires 7.

So here's my question: will you guys upgrade to libc++ 8 any time soon (in which case I'd just wait for that to happen) or do you wanna stay on 7 for the foreseeable future (in which case I'd need to figure out how to get the older library back)?

What compile error are you getting?

Code:

+ cd /home/user/gitbuilds/xonotic/gmqcc
+ make -j8 gmqcc
make: *** No rule to make target '/usr/include/c++/7/new', needed by 'ast.o'.  Stop.

In my investigation I noticed that /usr/include/c++/7 doesn't exist anymore, since I upgraded to Fedora 28, which replaced gcc-c++ 7 with version 8 (located in /usr/include/c++/8).

So my question is whether you guys are planning to upgrade that in your repo anytime soon or not. If not then I guess I'd have to install the older version again from a non-maintained package, which I don't like to do.

Or are there any other options?

Just "make clean". You have outdated build artifacts. Also, libc++ and libstdc++ are different projects and looks like you are using libstdc++.

Thanks! That solved it, I can now compile Xonotic as before; I don't normally compile stuff manually so I'm pretty clueless. In case someone stumbles upon this in the future: What I did specifically was to run 'all clean' and then the usual sequence ('all checkout', 'all update', 'all compile -r sdl').
