Mario:
How to use LibGD (http://www.libgd.org) with PellesC?
I do not succeed in getting the lib from the Dll, can you help me?
Thx
Mario

koala:

I have the same problem, some solution?

(Compilation run fine, but on run some gd functions like gdImageJpeg cause segmentation fault)

Meanwhile i use PellesC to write code and mingw to compile.

Thank You

Problem due to the wrong calling convention.
Define the symbol 'WIN32' in your projects.
From ide menu project->project_options->compiler add 'WIN32' in the symbol's define box.
From command line use switch '/D' to define symbol 'WIN32'.

koala:
I tried, but i have same problem.

On menu project->project_options->compiler  at the bottom, now appears:

Comand line options: (CCFLAGS)
 -Tx86-coff -Ot -W1 -Gz -Ze -DWIN32

is all right?

Thank You

frankie:
Ok the problem is the incompatibility of PellesC and M$ file I/O approach.
To use the precompiled dll you have to omit the default libraries and link the msvcrt.lib instead.
Please look at the attached sample.
