I added libpqxx (pqxx) via vcpkg to CMake project, however it's failed while building. Here is CMake code:

find_package(libpqxx CONFIG REQUIRED) target_link_libraries(PqDataBase PRIVATE libpqxx::pqxx)

And included header:

#include <pqxx/pqxx>

I tried a lot of alternatives of adding CMake, but no one works. It might need dynamic linkage, but I have no idea how it does.

Here is error message:

  • You used vckg to generate msvc binaries and are now attempting to link that with MinGW. For c based code that has a chance of working for c++ its unlikely to work. Commented May 22, 2024 at 22:42
  • I used the different packages that installed via vcpkg, they work smoothly with the same environment. Commented May 23, 2024 at 17:16
  • You need to use one of the MinGW triplets and not the msvc ones: https://stackoverflow.com/questions/63031513/vcpkg-with-mingw Commented May 24, 2024 at 12:30
  • I tried it, at the moment there is issue of installing of x64-mingw-dynamic packages. Now issue is opened on github, I will try it. Thank you. Commented May 24, 2024 at 17:56
