Error compiling dcraw_common.cpp

[LordJonas]

Hi.

After some time whitout working with CEGUI i'm back.

For some strange reason when i compile the cegui-dependencies i get this errors :

This is my working environment:

Windows 10 Pro 64 bits
Code::Blocks 16.01
MinGW64 v6.30 architecture i686 Threads posix Exception sjlj revision 2
Cegui-Dependencies v0.8
Cegui v0.87
CMake 3.8.0

Any sugestion ?

What dependencies version is this / where did you get it from?

[LordJonas]

Hi.

The dependencies package come from the link in the official page:

https://bitbucket.org/cegui/cegui-dependencies/get/v0-8.zip

[Ident]

Did you change the compiler settings? It seems like this is a warning counting as error, and the warning comes from FreeImage. Not much we, as CEGUI, can do about either of that, unless the project setting comes from our CMake (does it?)

[LordJonas]

Yes, the project settings were generated by CMake indeed...

I had tried with different compiler versions and as far i can tell only TDM-GCC x86-x64 v5.1 does not produce this error.

[LordJonas]

After some deep investigation in the web i found that mingw is compatible with FreeImage 3.15.0 until version 5.4. From version 6 this situation changes and you get those errors...

[Ident]

That's unfortunate. Be aware however that you can always use Silly or Devil instead of FreeImage. I personally use Silly, which is the loader CrazyEddie made by himself.

[LordJonas]

I could be crazzy but i'll try to incorporate FreeImage 3.17.0 in the cegui dependencies and see how it goes...

[Ident]

Ah I misread your previous post. So you say it should work fine with 3.15.0 ? Well, What happens if you ignore the warning and just go on?

[LordJonas]

Good question...

Let's try that...
