Hi Matthias,
I noticed in Ubuntu when trying to rebuild most packages against ldc 1.30.0
that they were now failing to build with current dh-dlang, because including
/usr/share/dh-dlang/dlang-flags.mk caused dpkg-buildflags' LDFLAGS to be
exported and these flags are not understood by ldc (specifically:
-Wl,-Bsymbolic-functions and -Wl,-z,relro on Ubuntu). This can be seen in
Debian in the failed build of gir-to-d:
[...]
../meson.build:1:0: ERROR: Unable to detect linker for compiler `ldc2
-L=--version /tmp/tmpsh_a2h39.d -Wl,-z,relro -O -g -release -wi --allinst`
stdout:
stderr: ldc2: Unknown command line argument '-Wl,-z,relro'. Try: 'ldc2 --help'
ldc2: Did you mean '--icp-lto'?
[...]
(https://buildd.debian.org/status/fetch.php?pkg=gir-to-d&arch=amd64&ver=0.22.0-3%2Bb1&stamp=1661202072&raw=0)
Paradoxically, there is support in dh-dlang for mapping these flags for ldc,
but this support is not included automatically in dlang-flags.mk.
I've applied the attached patch in Ubuntu, which fixes the build problem.
Thanks for considering,

Yes, I overlooked this! This was fixed in Meson and is working fine
for years now :-)
Best,
