digitalmars.D.learn - Newbie linker errors - still missing _fltused _tls_index _tls_used

reply malpropism <propellerhead nonexistent.con> writes:
I just ported my Java application to D, got it to compile, but 
not to link.

I'm using Windows 10 64 bit, DMD 2.088.0 , Visual D 0.50.1.  This 
would be a C/C++ project in Visual Studio with only D code.

With my first attempt, I'm missing 65 externals, 328 errors.

I added these two files

ucrt.lib
vcruntime.lib

to the Additional Dependencies in the linker property pages and 
have my missing external count down to 6, 70 errors.

I'm missing the following 6 symbols:

_fltused _tls_index _tls_used localtime tzset mainCRTStartup

What other libs would I need to add to the linker's additional 
dependencies?

I suspect you have disabled the C runtime library selection in the D
compilation options to build against the shared C runtime DLLs (you can
select that, too). Or your code might be missing a main function in
which case the selection might not be embedded into any object file.

In this case, you should add msvcrt.lib instead of vcruntime.lib.
Depending on used functionality you will also need
legacy_stdio_definitions.lib.

Thanks for very prompt reply and apologies for my extremely late 
answer.  Due to the current situation, I now have much more time 
to work on this.

In short, I upgraded to the most recent (1.20.1) LDC compiler, 
the most recent (0.52.0) Visual D, but am staying with VS 2017.

When I try to compile and link with "Release", the linker 
unresolved symbols problem goes away.  (Things which are too good 
to be true usually are)

When I try to compile and link with "Debug", I'm back to a 
similar state as before.   (429 errors, 175 unresolved externals)

I also tried adding a small .cpp file thinking it might trick the 
linker setup to add more files and libraries, I got more (455) 
errors.

When I save the linker output /VERBOSE:lib and compare the linker 
output, I have appended what stands out: (that is, missing from 
Debug yet present in Release)

Thanks for your suggestion.  In VS 2017, the Property Pages have 
a configuration drop down list box which allows you select among 
Active(Debug), Debug, Release, and All Configurations.  Mine was 
set to All Configurations, leaving me to believe that setting 
something would apply to both Debug and Release.   On the surface 
it seemed to work, setting one or another parameter was felt in 
both Debug and Release.  Verbose -v compilation, for example.

Your message gave me the idea to check the .vcxproj file directly 
and sure enough, Debug and Release were (quite) different, the 
relevant offending bit of XML in the Debug linker area was

<IgnoreAllDefaultLibraries>true</IgnoreAllDefaultLibraries>
