c++ - Qt5 cmake Windows Linker Error -

-



i wanted start new project uses qt in combination cmake. (hope i) followed docs, seems if linker not doing work correctly:

cmakefiles\qttest.dir/objects.a(main.cpp.obj): in function `qstring::qstring(char const*)': p:/qt/5.9.1/msvc2015_64/include/qtcore/qstring.h:659: undefined reference `__imp__zn7qstring16fromascii_helperepkci' cmakefiles\qttest.dir/objects.a(main.cpp.obj): in function `qtypedarraydata<unsigned short>::deallocate(qarraydata*)': p:/qt/5.9.1/msvc2015_64/include/qtcore/qarraydata.h:237: undefined reference `__imp__zn10qarraydata10deallocateeps_yy'

i'm using mingw-w64 (the x86_64 installation) clion , bundled cmake , qt 5.9.1. cmakelists.txt looks this:

cmake_minimum_required(version 3.8) project(qttest)  set(cmake_cxx_standard 14) set(cmake_module_path ${project_source_dir})  set(cmake_verbose_makefile on)   # qt set(cmake_include_current_dir on) set(cmake_automoc on) set(qt5_no_link_qtmain on)  set(cmake_prefix_path p:/qt/5.9.1/msvc2015_64/lib/cmake) find_package(qt5core required)  get_target_property(qtcore_location qt5::core location) message("qtcore version ${qt5core_version} @ ${qtcore_location}")  # qttest executable set(source_files main.cpp) add_executable(qttest ${source_files}) target_link_libraries(qttest qt5::core)

when creating build files outputs (correctly) qtcore version 5.9.1 @ p:/qt/5.9.1/msvc2015_64/bin/qt5core.dll main.cpp contains call qstring testing purposes:

#include <qtcore/qstring>  int main() {     qstring string = qstring("test"); }

why happen?

i have many .npy (numpy) , .json files saved in s3, need download , load these files. for json files downloading files , loading dictionary using following code: obj = s3.object(bucket, key) response = obj.get() body = response['body'].read().decode('utf-8') data = json.loads(body) that way avoid writing .json file disk , reading it. now want same .npy files, equivalent? currently downloading file, saving temp file on disk , loading np.load avoid if possible. following https://stackoverflow.com/a/28196540/3509999 : obj = s3.object(bucket, key) io.bytesio(obj.get()["body"].read()) f: # rewind file f.seek(0) arr = np.load(f) wiki
