Answer using chatGPT
{
This error is usually caused by incorrectly defined rules in the Makefile. In this Makefile rule, the error message error: multiple target patternsmeans that the make tool cannot resolve the name of the target file.
You need to put both the dependency and the command on the same line, and use a colon to separate the target file and the dependency. Here is a modified rule:
debug/qrc_res.cpp: res.qrc C:/Qt/6.5.0/mingw_64/bin/rcc.exe Active\ code\ page:\ 65001
C:/Qt/6.5.0/mingw_64/bin/rcc.exe -name res --no-zstd res.qrc -o debug/qrc_res.cpp
Note that we have changed the path separator for the output files in the command. In addition, if you Active\ code\ page:\ 65001just want to specify the encoding format, you can delete this line or specify the encoding format directly in the command.
You can then rerun the make tool to build your project.
