Antonio, ¡estoy inquieto!

[José Vicente Beltrán]

Antonio,
Veo con cierta inquietud que nuestro barco se está decantando de manera muy clara por Harbour, y esto no sería malo si no fuera porque implicitamente está abandonando xHarbour. Espero estar equivocado, porque mi problema, y supongo que no soy el unico que lo tiene, es que algunos de mis programas mas veteranos y por tanto con un desarrollo mas complejo, con funciones muy especificas desarrolladas a lo largo de años (20 en algún caso) y que están funcionando muy bien bajo xHarbour 1.2.3 no es posible cambiarlos a Harbour, secillamente porque no compilan o lo hacen con muchos errores, lo que hace imposible el proceso de paso.
la diferencia ahora mismo entre Harbour y xHarbour es notable y en mi caso concreto insalvable porque no se puede reescribir una aplicación del tipo expuesto sin hacer pasar a los clientes por un nuevo proceso de pruebas superado ya hace mucho tiempo, y que para mas inri resulta que suelen ser los clientes mas importantes
Iniciar con Harbour 32/64 bits los nuevos programas está muy bien porque el mercado y las tendencias cambian, pero ¿que hacemos con los casos como el que acabo de exponer?, acaso ¿no habrá nuevas actualizaciones del compilador xHarbour?, ¿Como se le dice a determinados clientes que la aplicación que usan como centro de su sistema ya no va a cambiar al ritmo esperado?

Pues lo dicho, necesitaba exponer este pensamiento, asi que... ¡sigo inquieto!

Saludos

Mi pequeña experiencia hizo que pasar de xHarbour a Harbour no sea nada. Literalmente nada o casi, sólo un par de lineas pero nada más. Me costó configurar el xEdit ( con el cual programo y compilo ) Una Vez hecho esto, fue sólo presionar un botón
Entiendo que mis programas no son complejos, pero tienen sus 10 años de desarrollo al menos y una vez compilado ningún error en funcionamiento. Tal vez si nos pasas tus errores entre todos salga la solución y tu paz para no estar tan inquieto.

Abrazo

José Vicente,

No tienes por qué preocuparte, acabo de revisar el repositorio de xHarbour y sigue activo:

http://sourceforge.net/p/xharbour/code/HEAD/tree/trunk/xharbour/ChangeLog

Asi que si necesitas, por el motivo que sea, seguir trabajando con xHarbour puedes estar tranquilo. Y aqui, por supuesto, seguiremos dando soporte técnico siempre a xHarbour, porque nuestros usuarios son lo primero y jamás dejaríamos a nadie "tirado"

Lo que si está claro es que Harbour ha superado ya con creces a xHarbour y de ahí que recomendemos a todos que migreis a Harbour.

Pero lo dicho, tienes todo nuestro soporte como siempre y a todos los usuarios que tengan que seguir con xHarbour

Maestro Antonio, una pregunta:

Se tengo FWH64 Bits, y recompilo las librerias de FiveWin 64 con el compilador de xHarbour 32 Bits, funciona normal ó no?

Gracias, saludos.

[Antonio Linares]

João,

xHarbour no funciona en 64 bits que yo sepa, asi que lo que planteas no es posible

Y además de eso, muchas funciones internas de xHarbour no tienen equivalencia en Harbour

[José Vicente Beltrán]

Está claro que el futuro, en estos momentos pasa por Harbour, pero os aseguro que el problema para mi es serio porque hablo de aplicaciones que interactuan con módulos escritos en delphi, Java, incluso VB en algún caso. (solo pensar en un traspaso a Harbour, se me baja la tensión), por cierto que gran parte de la integración con aplicaciones desarrolladas en delphi es gracias a los (tan denostados) indices NTX, solo quería dejar constancia de ello, y leer de Antonio lo que acabo de leer , lo cual me apacigua la 'inquietud' de alguna forma

Gracias

[Manuel Valdenebro]

Jose Vicente,

Recientemente he pasado una aplicación importante desde xHarbour a Harbour. Logicamente, cualquier cambio trae complicaciones, en mi caso ha sido el tema de los Codepage. Pero una vez solucionado esto, el cambio de Harbour a xHarbour no ha sido demasiado complicado.

Yo sigo trabajando con xHarbour, pero he hecho pequeñas modificaciones en los módulos para hacerlos compatibles y compilo en xHarbour para los clientes y en Harbour para mi, para ir probando. Eso me va a permitir, por ejemplo, cuando los clientes exijan 64 bit, poder compatibilizar 32 bit y 64 bit sin mucho jaleo.

Soy receloso para los cambios, cuando la cosa funciona. Tarde tiempo en pasar de Clipper a FiveWin y de FW a FWH. Esta vez prefiero estar preparado.

[José Vicente Beltrán]

Hola Manuel,
Gracias por compartir tu experiencia, algo parecido he intentado yo, pero por el momento he sido derrotado en toda regla, de ahí "mi bajón", de todas formas tus palabras me animan a seguir intentando el "paso".

Saludos

Foro,

Creo que algun dia llegare a migrar y ya lo he pensado, mi problema principal y que me preocupa, radica en que uso tmysql y veo que no esta en harbour.

Me diran que use tdolphin, se que no es mala la idea y si la usaria en nuevos desarrollos.

Pero, alguien ha podido adaptar tmysql de xHarbour para Harbour ?

Saludos

[Antonio Linares]

Paco,

Tienes el código fuente de la Clase TMySQL ?

De ser asi, por favor publícalo aqui y te ayudamos a compilarlo con Harbour

[Francisco Horta]

Antonio,

Paco,

Has intentado compilarlo con Harbour ? Añade ese PRG como uno más de tu aplicación

[Francisco Horta]

Antonio

Voy a probarlo y comento

Pues retomando el tema despues de un rato, estoy tratando de crear la lib de la clase tmysql que uso en xharbour para usarla con harbour,

pero me tira estos errores, y pues la verdad no entiendo de .c y veo que es los wrappers de mysql.c

alguien que me pueda ayudar?

adjunto los errores y el codigo de mysql.c
