[SOLVED] Stuck compiling libc++

tazza · 12-20-2017, 08:00 PM

After a bit of searching, I found the following: https://www.linuxquestions.org/quest...ng-4175612648/

stating that xlocale.h has been removed and that there is a commit found at: https://github.com/llvm-mirror/libcx...57563164dd327e

The thing is, how do I use it? I've tried searching how to use a patch and found things like "patch -p0 <patchname>' but when I run it the system just sits there doing nothing.

I need it to get discord running, and after seeing the dependency list for libc++ am using sbopkg for the first time ever. Pretty happy so far

You should be using ponce's repo if you're using -current. Regular SBo only is tested against the latest stable (14.2 right now), but ponce maintains a custom repo that tries to keep up with -current. He has a patch for libc++ to deal with xlocale.h up there.

See his thread for details on how to use it. (Hint: this is how to use it with sbopkg.)

While bassmadrigal is right here, to answer the original question...

Any commit or pull request at github can be turned into a patch by adding '.diff' or '.patch' at the end of the url. For example.

https://github.com/llvm-mirror/libcx...164dd327e.diff
https://github.com/llvm-mirror/libcx...64dd327e.patch

This then can be then applied to the source tree with.

Code:

patch -p1 -i /path/to/foo.patch

Or the commit can be reversed.

Code:

patch -R -p1 -i /path/to/foo.patch

Additionally the repo can be cloned and you can use git to do these and much more.

I didn't need a patch when I built it (version 5.0.0) on -current three weeks ago.

thanks for this: I had switched to 4.0.1 when I updated it on august because it wasn't building on current but I'll move to 5.0.0 now.

Well it doesn't work now

I also lost my VPN connection today and random mac address, I've seen this addressed in other questions and will deal with it when I get time.

Code:

3 warnings and 1 error generated.

libc++:

it cannot because you are still using the 14.2 repository with sbopkg (and it looks like you are on current): see the first answer you got in this topic

Thanks, I know and I will.. as I said in my prior message.. "I'll look into the other recommendations in this thread and report back." Other things going on at the moment.

Ok. All sorted.

Special thanks to Orbea in explaining how things actually work.

Also thanks to Bass for the links. I didn't do it that way but have upgraded my sbopkg.conf accordingly, so in the future it will be referencing current. As I mentioned, sbopkg is new to me (normally grabbing a few dependencies is no big deal) but great to know some of the larger packages can be handled automagically.

Cheers.
