mscv fatal error LNK1181: cannot open input file

The Meson build system
Version: 1.6.0
Source dir: D:\a\canfigger\canfigger
Build dir: D:\a\canfigger\canfigger\builddir
Build type: native build
Project name: canfigger
Project version: 0.3.1999
C compiler for the host machine: cl (msvc 19.41.34123 "Microsoft (R) C/C++ Optimizing Compiler Version 19.41.34123 for x64")
C linker for the host machine: link link 14.41.34123.0
Host machine cpu family: x86_64
Host machine cpu: x86_64

When I try to build the tests:

fatal error LNK1181: cannot open input file 'canfigger.lib'

To build the library and declare it, I have

buildtarget = library(
  meson.project_name(),
  src,
  version : meson.project_version(),
  install: not meson.is_subproject()
  )

# How to use in a superproject and other info
# https://mesonbuild.com/Subprojects.html
canfigger_dep = declare_dependency(
  include_directories : include_directories('.'),
  link_with : buildtarget
  )

For the exe tests, I use 'canfigger_dep' as the dependency.

What is the proper way to do this so the tests will build on Windows? They already build on Linux, MacOS, and BSD. (All my changes are in this pull request.

MSVC defaults to hidden visibility; if no symbols are public in a shared library, it will not create the corresponding .lib file. You would need to tag the public symbols with __declspec(dllexport) or provide a symbol list with the vs_module_defs argument.

Thanks @QuLogic I'm now using this def file:

; canfigger.def
LIBRARY "canfigger"
EXPORTS
    ; Export functions for use in other applications
    canfigger_parse_file
    canfigger_free_current_key_node_advance
    canfigger_free_current_attr_str_advance

The tests are building but failing to run:

exit status 3221225781 or signal 3221225653 SIGinvalid

Seems to work better when I link statically:

if build_machine.system() != 'windows'
  buildtarget = library(
    meson.project_name(),
    src,
    version : meson.project_version(),
    install: not meson.is_subproject(),
    )
else
  buildtarget = static_library(
    meson.project_name(),
    src,
    install: not meson.is_subproject(),
    # vs_module_defs: 'canfigger.def'
    )
endif

Unfortunately, 1/8 tests passed, 1 failed, and the rest timed out.

Unfortunately, 1/8 tests passed, 1 failed, and the rest timed out.

Using "rb" as the second argument to fopen() fixed most. 6/8 pass now, 2 timeout. So... not really a meson issue of course.

So I guess the question remains, Should I just use static libraries on Windows? Or what step did I miss after I added the def file and all the tests built, I just got exit status 3221225781 or signal 3221225653 SIGinvalid is:closed for all of them?
