Hola Antonio:

Al enlazar me pone

Error: Unresolved external '_png_init_io' referenced from C:/FWH\LIB\FIVEHC.LIB|FWPNG
Error: Unable to perform link

Que debo corregir.

Un saludio

Carlos

Antonio,

Excelente idea.

Sin embargo, este Harbour da el siguiente error:

Error: Unresolved external '_png_init_io' referenced from C:\FWH\LIB\FIVEHC.LIB|FWPNG

Mr Antonio

There is no call to any function in FWPNG module in the entire FWH libraray
Then why is the FWPNG is linked requiring png.lib?

I am using both Harbour (3.2) and xHarbour without png.lib for all development work.
Why should there be any difference with Harbour 3.4?

Hi, I'm not using any FWPNG function, but If I take png.lib off I get more unresolved external

regards

Ruben Dario Fernandez.

Are you directly using any functions from FWPNG.PRG in your application?

If not, there is no need to link png.lib from 15.02 onwards.

Estimados: Me da error con la version 1503 y Harbour 3.4

Unresolved external '_png_init_io' referenced from C:\FWH1503\Lib\FiveHC.lib|FWPNG
Tengo png.lib incluida en el proyecto...
Gracias
