Quazip-1.3 static linking issue

231 views Asked by At

I have built Quazip-1.3 libs statically with zlib-win-build-1.2.12 (build-VS2019-MT) - libz-static.lib. When I try to build my project then I get a lot of linking errors:

LINK : warning LNK4217: symbol '?commit@QSaveFile@@QAE_NXZ (public: bool __thiscall QSaveFile::commit(void))' defined in 'Qt5Cored.lib(qsavefile.obj)' is imported by 'quazip1-qt5d.lib(qioapi.obj)' in function '"bool __cdecl quazip_close(class QIODevice *)" (?quazip_close@@YA_NPAVQIODevice@@@Z)'

    system("Pause");

I have used these commands to build QuaZip statically:

cmake -DCMAKE_BUILD_TYPE="Debug" -DCMAKE_MSVC_RUNTIME_LIBRARY="MultiThreadedDebug" -DBUILD_SHARED_LIBS=OFF -S . -B C:/ZipDev/quazip-1.3/msvc2019/static/x86/debug -D QUAZIP_QT_MAJOR_VERSION=5 "-DCMAKE_PREFIX_PATH=C:/Qt/5.9.9/msvc2019" -DZLIB_INCLUDE_DIR="C:/ZipDev/zlib-win-build-1.2.12" -DZLIB_LIBRARY="C:/ZipDev/zlib-win-build-1.2.12/build-VS2019-MT/Debug/libz-static.lib" -G "Visual Studio 16 2019" -A "Win32"

cmake --build C:/ZipDev/quazip-1.3/msvc2019/static/x86/debug --config Debug

Also, I have checked the QuaZip library - quazip1-qt5d.lib using lib /list and dumpbin /directives.

The issue only occurs with Quazip static libs, dynamic libs are working well. What could cause such errors with static libs? Thank you.

I have created my own CZip library which adds content to archive and extracts it. The issue is resolved.
