Compilation Error on Ubuntu 18.04 (

[sroycode]

Hi:

On Ubuntu 18.04 , configured with "./configure --with-included-rocksdb --with-included-boost --prefix=${HOME}/.local",
libicu-dev version 60.2-3ubuntu3.1

I am getting the following error in "make"

                 from /usr/include/unicode/utypes.h:44,

                 from icu.cc:16:

It looks like you're missing libicu. I don't have the exact package name but it might be libicu-dev or libicuuc-dev. It turns out this package should be optional and that code shouldn't be compiled when it's not available, so I will fix that.

libicu-dev version 60.2-3ubuntu3.1 is already there , is there a version related issue ?

[jevolk]

Sorry for jumping the gun. Do you have some information about your platform and version for libicu compiler? Also unfortunately Ubuntu 18.04 is no longer really tested here as we're developing on 20.04 now, but it was used for a long time and did work. I'd like to get to the bottom of this and keep it working.

I pushed a potential fix to my staging repository at https://github.com/jevolk/charybdis.git but I haven't tested it with your libicu version 60.2 (I'm using 66.1 here). Feel free to pull master from this repository and report if there are additional compilation errors beyond this.

Hi:
Charybdis went through on that step, gave another error:

Thanks! What compiler version?

Thanks! What compiler version?

Yes, unfortunately this is a bit too old at this point. If you try to export CXX=g++-8 and then reconfigure that should work on Ubuntu 18.04. As an aside, you may need to git clean -f -x -d before running configure again (though you may not, but we've had reports of trouble when performing similar things).
