Hi, Ruoyao,
In my CMakeLists.txt, I specify below:
include_directories(
"/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-linux-musl/include/c++/13.2.0"
"/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/lib/gcc/i686-linux-musl/13.2.0/include/ssp"
"/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-linux-musl/sysroot/usr/include"
"/home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-linux-musl/sysroot/usr/include/asm"
"/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"
)
The same errors still occurred and then I used the full path to specify in head files as follows:
#include </home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/i686-linux-musl/include/c++/13.2.0/cstring>
#include </home/Dingjun.Chen/x-tools/HOST-x86_64-pc-cygwin/i686-linux-musl/lib/gcc/i686-linux-musl/13.2.0/include/ssp/string.h>
The same errors still occurred. I do not know why? Did I do something wrong?
I look forward to your help!
Thank you very much for your reply!
Best regards,
Dingjun

Correction: should be "i686-linux-musl-cpp" instead of "cpp" for your configuration.
