Re: Requesting Help on libcurl compile

Hello, Ray. I appreciate the response.

I added -lcrypt32 to the original code and successfully was able to resolve
most errors to just the following:

C:\msys64\mingw64\bin\..\lib\gcc\x86_64-w64-mingw32\12.2.0\..\..\..\..\x86_64-w64-mingw32\bin\ld.exe:
C:\libs\curl_new64\lib\libcurl.a(strerror.o):strerror.c|| undefined
reference to `__imp___sys_nerr'
C:\msys64\mingw64\bin\..\lib\gcc\x86_64-w64-mingw32\12.2.0\..\..\..\..\x86_64-w64-mingw32\bin\ld.exe:
C:\libs\curl_new64\lib\libcurl.a(strerror.o):strerror.c|| undefined
reference to `__imp___sys_errlist'

The following compiled successfully:

  #include <stdlib.h>
  #include <stdio.h>

  int main(int argc, char *argv[])
  {
     /* print from errlist such as "Illegal byte sequence" etc */
     printf("%s\n", _sys_errlist[_sys_nerr - 1]);
     return 0;
  }

But in the following, I received an *"Illegal byte sequence"* output:

  #include <stdlib.h>
  #include <stdio.h>
  #include <curl/curl.h>

  int main(int argc, char *argv[])
  {
     /* print from errlist such as "Illegal byte sequence" etc */
     printf("%s\n", _sys_errlist[_sys_nerr - 1]);
     return 0;
  }

Thank you!
