That is a convenience wrapper to diet-ng:

Instead, create your own output range (maybe a char[]
appender?) and compile to that yourself:
import diet.html : compileHTMLDietFile;
import std.array : appdender;
auto app = appender!(char[]);
compileHTMLDietFile!("index.dt")(app);
auto resultingHTML = app.data;

Thank you very much.

[1]: https://www.tockos.org https://man7.org/linux/man-pages/man3/dl_iterate_phdr.3.html dl_iterate_phdr is used to iterate over the elf program headers and is used to get a textual back trace among other things. These are typically calls found in Linux systems and if you don't have that, you have to replace them with your own calls or just remove the call all together. Much of the elf stuff can be removed. The only things that might be essential is that druntime needs to know where the TLS data is per thread for scanning.

cant' help much but just in case - see
https://github.com/ldc-developers/ldc/pull/2405#issuecomment-346187456,
may be it helps
also you can define this symbol yourself with assert(0) to check if it
is called at all
what about - quick glance at
https://linux.die.net/man/3/dl_iterate_phdr says us that this symbol is
used only with shared objects so you can try to define it yourself with
assert(0) like this (not tested!!!):
```D
extern(C):
alias Callback = int function (void*, size_t, void*);
int dl_iterate_phdr(Callback callback, void* data)
{
assert(0);
}
```
this lets you to link druntime at least and if those symbols were called
abort the execution
