As we've advised before: 1) Build 6.6, not any older version 2) Build in shared mode, not static 3) Build each module separately, not the top-level Once all of the above are working for the modules you're interested in, you can try 6.5. And once 6.5 builds in shared mode, you can try static. I don't think it's a valid request to try 6.2 in static right now. The only reason to build 6.2 in static is if you've already got an existing project building with 6.2 in static right now and want to continue releasing it. That's obviously not the case. Since you're clearly starting a new project, you must start with the latest stable or latest LTS. And if the modules build independently, then you're done. The top-level build is a convenience. That means if it works, great; if it doesn't, then you already had a solution. > > -- CMAKE_BUILD_TYPE was set to: 'Release' > > -- Performing Test HAVE_FFI_CALL > > -- Performing Test HAVE_FFI_CALL - Success > > -- Found FFI: C:/msys64/mingw64/lib/libffi.dll.a > > -- Found ZLIB: C:/msys64/mingw64/lib/libz.dll.a (found version > > "1.3.#define ZLIB_VERSION "1.3"") > > CMake Error at C:/msys64/mingw64/lib/cmake/zstd/zstdTargets.cmake:42 > > > > (message): > > Some (but not all) targets in this export set were already defined. > > > > Targets Defined: zstd::libzstd_static > > Targets not yet defined: zstd::libzstd_shared Looks lik the CMake-provided zstdTargets doesn't support static mode on Windows. Maybe it doesn't support static modes at all or just on Windows. I don't know whether those files come from CMake itself or from Zstandard -- I am guessing the latter. Therefore, you can submit your bug reports here: https://github.com/facebook/zstd If you don't care about the library sizes and decompression performance, you can turn zstd support off in Qt, by passing -DFEATURE_zstd=OFF. > After reading the log, I think it is because the configure process called > find_package(zstd) twice: > > 1.

Yes: don't build from the top-level. I told you that months ago. -- Thiago Macieira - thiago.macieira (AT) intel.com Cloud Software Architect - Intel DCAI Cloud Engineering
