Hi,

My build suddenly failed after my OS upgrade to Ubuntu 22.04 LTS

$ cat /etc/issue.net
Ubuntu 22.04 LTS

$ dpkg -l | grep -i ldc
ii ldc 1:1.28.0-1ubuntu1 amd64 LLVM D Compiler
ii libphobos2-ldc-shared-dev 1:1.28.0-1ubuntu1 amd64 LLVM D Compiler - Standard and runtime libraries, imports
ii libphobos2-ldc-shared98:amd64 1:1.28.0-1ubuntu1 amd64 LLVM D Compiler - Standard and runtime libraries

But, I'm using my local install ldc 1.29's dub to build, which pick up the ldc2 compiler correctly (see below the build dir name), but I run into lots of link errors:

/usr/bin/ld: //home//.dub/packages/dateparser-3.0.4/dateparser/source/dateparser/package.d:752: undefined reference to `_D3std8datetime8timezone9LocalTime7stdNameMxFNbNdNlNeZAya'

...

/usr/bin/ld: /home//.dub/packages/requests-1.1.7/requests/.dub/build/std-unittest-linux.posix-x86_64-ldc_v1.29.0-6C686308E30390EDCF080BEEC5E5A4C4/librequests.a(requests.pool.o):(.data._D29TypeInfo_S4core4time8Duration6__initZ+0x40): undefined reference to `_D4core4time8Duration8__xopCmpMxFKxSQBiQBgQBeZi'

After uninstall system packages:

$ sudo apt-get purge ldc libphobos2-ldc-shared98 libphobos2-ldc-shared-dev

The build succeed. But I'm just wondering why it mess up the local install and the system install; maybe it confuse the two conf files?

/my/local/ldc2/etc/ldc2.conf

/etc/ldc2.conf

A ../etc/ldc2.conf relative to the executable should take precedence over system-wide /etc/ldc2.conf. Running with -v shows the used config file and the invoked C compiler cmdline for linking, which should contain a -L<path to local lib dir> -lphobos2-ldc -ldruntime-ldc, supposedly making sure the local libs take precedence over the system libs.
