no tengo este problema en Linux, así que no sé por qué sucede esto en las ventanas. Ya lo busqué en Google y no encontré nada, excepto los archivos de la lista de correo, con la misma pregunta y respuesta diciendo "google it".¿Cómo resuelvo estos errores de enlace de libcurl?
estoy usando MinGW. Obtuve algunas advertencias del enlazador cuando construí libcurl pero parecían estar relacionadas con SSL y no sé si es un gran problema porque se construyó sin errores.

Hm. Pensé que libcurl creó tanto estática como dinámica. Intenté -DCURL_STATICLIB pero ahora recibo cientos de errores del enlazador, por ejemplo, referencia indefinida a WSAStartup @ 8, _imp__ares_library_init, ntohs @ 4, getsockopt @ 20 etc. – VVV

No está enlazando en ninguna de las bibliotecas dependientes. Necesitarás (al menos) -lwinsock2' plus cualquiera que sean los indicadores '-l' para las demás bibliotecas (parece que OpenSSL y posiblemente uno o dos más). –
