Symbol lookup error

[KingDuckZ]

Hello, compiling this with meson 1.6.1 and gdc 14.2.1, I'm getting this error when I start my program (just an empty main):

[9/10] Generating symbol file subprojects/dyaml/libdyaml.so.0.10.0.p/libdyaml.so.0.10.0.symbols
./src/animerelink: symbol lookup error: /home/michele/dev/rambuild/animerelink/debug/src/../subprojects/dyaml/libdyaml.so.0: undefined symbol: _D3std9algorithm9searching__T3allSQBg6format8internal5write__T20formatValueImplUlongTSQDg5array__T8AppenderTAyaZQoTaZQCdFKQBlmIbMKxSQFaQDu4spec__T10FormatSpecTaZQpZ10__lambda16Z__TQFvTAaZQGcMFNaNfQmZb

demangled it looks like:

pure @safe bool std.algorithm.searching.all!(std.format.internal.write.formatValueImplUlong!(std.array.Appender!(immutable(char)[]).Appender, char).formatValueImplUlong(ref std.array.Appender!(immutable(char)[]).Appender, ulong, in bool, scope ref const(std.format.spec.FormatSpec!(char).FormatSpec)).__lambda16).all!(char[]).all(char[])

Note that meson.build seems to be missing 'source/dyaml/stdsumtype.d' and the lib version is set to 0.8.4. Adding stdsumtype.d gets me past the first error and produces the one above. This only happens when building a .so, static lib seems to link and run fine.
