Today's GCC 9.1 update. Does it break anything?


I found that the recent -current has updated GCC with a major version bump (along with a new option in LLVM, thanks, Patrick Volkerding!).

Does it break much? I have some important stuff on my machine compiled with GCC 5, so that shouldn't matter much, but as far as I remember, C++ (NOT pure C) doesn't guarantee linking compatibility even between different major versions of the same compiler.

Should I wait for glibc and friends to be recompiled with GCC 9, or just roll the update on?

This is a relevant question. I'd like to know as well.

Did we get the D language support (gcd), I don't see It in the SlackBuild?

gcc is used to compile stuff, not to run it.

A little of each, really. The gcc-g++ package supplies libstdc++.so.6, for example. But with the versioned symbols that have been in use for a long time, it's unlikely that a newer libstdc++ will break anything.

Don't think so. I don't find it on my system.

Well, I did update the system after all, and everything seems to be working okay.

I realize that Didier. What I meant is other programs are still running fine having been compiled with an earlier version of gcc. That has not always been the case with earlier versions of gcc.

Woops.

My Konqueror broke down.

There was an error loading the module WebKit.
The diagnostics is:
Cannot load library /usr/lib64/kde4/kwebkitpart.so: (/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /usr/lib64/libQtWebKit.so.4))

When re-installing the nvidia blob, it complained that the kernel was compiled with the previous version of gcc. I told it to go ahead and everything is fine.

I stand corrected, thanks for the heads-up.

After update my KDE can't start. It dies on first icon (disk) and return to login window.
Hopefully XFCE works.
