FW: Error from memcpy in cstring

[Dingjun Chen]

Hi, Ruoyao, 

Thanks indeed for your advice. After I change 'include_directories' below and then the errors occurred before are gone. 

Thanks again and have a great day, 

Best regards, 

Dingjun


include_directories(
        "/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/lib/gcc/i686-linux-musl/13.2.0/include/ssp"
        "${PROJECT_SOURCE_DIR}/include"
        "/home/Dingjun.Chen/usr/include/rtd"
        "/home/Dingjun.Chen/usr/include/gsc"
     )

All entries above just seem wrong.

/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-
linux-musl/include/c++/13.2.0 should be a default system C++ header path.

/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-
linux-musl/sysroot/usr/include should be a default system header search paths if --sysroot is used correctly.

The other paths contain internal implementation details, and they should never be used with -I.

In this case /home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-
linux-musl/lib/gcc/i686-linux-musl/13.2.0/include/ssp contains a string.h, so using it with -I causes #include <string.h> to find a wrong string.h.
