Not the answer you'll probably want to hear, but:

- Use an up-to-date compiler

- Use package distributions like vcpkg or conda-forge that already brings all the dependencies "for free"

- It seems you mix builds of different compilers (VS vs mingw). That's a bit asking for troubles ;-)

Resend with more information:

I am trying to build GDAL 3.8.4 on windows under VS2015. The build failed at linking stage that a bunch of external symbols not found, specifically the symbols in libproj, libcurl. I checked the dll library stub .lib for libproj and libcurl using “dumpbin” and found the symbols in the library a little different, for example the linker error shows “__imp__curl_slist_append” not found, the symbol output from the “dumpbin” is “__imp_curl_slist_append” .

Any idea how to fix this?

Thanks!

GDAL 3.8.4 build on Windows from VS2015 x64 command prompt: “cmake –build .” throws the following error (there are more similar errors):

cpl_vsil_az.obj : error LNK2001: unresolved external symbol __imp__curl_slist_append [E:\gdal-3.8.4\build\GDAL.vcxproj]

cmake options has:

set (GDAL_USE_CURL                ON   CACHE  BOOL "" FORCE)

set (CURL_INCLUDE_DIR "E:/SDK/curl-8.6.0_1-win64-mingw/include" CACHE PATH "" FORCE)

set (CURL_LIBRARY_RELEASE "E:/SDK/curl-8.6.0_1-win64-mingw/bin/libcurl-x64.lib" CACHE FILEPATH "" FORCE)

libcurl-x64.lib is the DLL stub. Using dumpbin on libcurl-x64.lib shows that “__imp_curl_slist_append” is available. But the linker error is “__imp__curl_slist_append” not found. There is an extra “_” in it.

Any idea why this error occurred?

Thanks!
