Title: [SOLVED] Compiling libPNG failing on pre-build steps, "copy" or "xcopy"
Post by: Melchior on July 22, 2017, 09:13:32 am

After importing from the
- .\lpng1630\projects\visualc71\libpng.vcproj

"copy"  doesn't  work because it creates a prompt for overwrite confirmation
regardless if  the file exists or NOT.. and because its in the compile log there is no way to interact
with said prompt...

so I resorted to modifying the cmdline from/to:

Code

from: "copy ..\..\scripts\pnglibconf.h.prebuilt ..\..\pnglibconf.h"

to  : "xcopy ..\..\scripts\pnglibconf.h.prebuilt ..\..\pnglibconf.h /Y"

even though...
and even then it only works if I manually copy and rename said file
first.. its strange.. and annoying...

idk.. if you could figure out a fix for that too?, please.

I FOUND this.... after an extensive Google search..

Code

echo f | xcopy /Y /F ..\..\scripts\pnglibconf.h.prebuilt ..\..\pnglibconf.h 

works from a .cmd batch file BUT fails inside of CodeBlocks... XD
go figure....

then this

Code

echo.>pnglibconf.h
xcopy /Y /F ..\..\scripts\pnglibconf.h.prebuilt ..\..\pnglibconf.h

works from cmd prompt or bat file BUT again fails in C::B..
does C::B NOT like the "echo" command???

so I tried this from the same site/article,
C::B didn't like it eirther so,
then modified to add "cmd /C"
IT WORKS, C::B LIKED THAT!!! lol :D : D

Code

cmd /C type ..\..\scripts\pnglibconf.h.prebuilt > ..\..\pnglibconf.h
