Problemas con DLL en C++

[pacoman]

Buenas, soy nuevo en C++ y he aprendido un poco lo básico para hacer un trabajito puntual.

Estoy haciendo un programa para enviar un e-mail. Me he basado en [URL="http://www.marshallsoft.com/"]SEE4C SMTP/POP3/IMAP Email Engine Library for C/C++ and .NET[/URL] que contiene un DLL.
Bueno, he hecho este esbozo del futuro programa con los ejemplos que da pero al compilar me dice "[linker error] undefined reference to" y a continuacion todas las funciones ejecutadas que tendrían que salir del DLL.

(*)


He estado buscando pero no he encontrado salucion para arreglar el error.

(*) Es muy grande el código y no me deja publicarlo, ¿cómo lo puedo subir?

No es un problema con el codigo propiamente dicho, no estas enlazando la libreria de importacion (see32.lib o see64.lib).

PD. Lee el "_READ_ME_NOW.TXT" en \APPS\, ahi figuran los proyectos, makefiles, etc. para usar con cada entorno, el tuyo por el error que dio debe ser este: GCC.ZIP : Command batch files for MinGW GCC.

[pacoman]

Pero cual de todos tengo que utilizar?

[Eternal Idol]

¿Estas haciendo un programa de 32 bits? see32.lib

[pacoman]

Pero hablo del zip que me has mencionado antes, ¿cual de los bat debo utilizar y como?

==

Siento que puede que te maree un poco pero es que yo programo de normal PHP y HTML y en C++ estoy un poco en el vacio.

[Eternal Idol]

Si te fijas son todos mas o menos iguales, cambia el .c y el .exe:

gcc -Wall gb2312.c see32.lib -o gb2312.exe

Usa una linea de comandos como esa o agrega el .lib al proyecto en el IDE que uses.

[pacoman]

me sale el mismo error.

He probado la línea de comandos esa pero me dice que no es un archivo por lotes y el agregar el dll (que por cierto se llama see32.dll, por si tiene eso la culpa) no ayuda...

==

Pd.: Uso Dev-C++

[Eternal Idol]

No tenes que usar la DLL, sino la libreria de importacion (.lib). Proba esto:

http://www.rohitab.com/discuss/topic...evcpp-project/

"try alt-p -> parameters -> add library or object -> navigate to your library -> click ok -> click ok -> F9"

Si la linea de comandos falla por no encontrar el gcc entonces buscalo en el disco, es un ejecutable (gcc.exe).

[pacoman]

Sí, lo encontré!!

Yo estaba encabezonado en el dll y era el lib.

Gracias!!!
