Problem compiling transupp.cpp

Hi.

I'm getting compiling problem of transupp.cpp.. Is it something in my
enviroment? Can I "fix" it somehow, by removing dllimport? (how?) Or
should I just disbale related component(s)?

Did this appear only recently?
Then it must be related to CMake include dir changes. Gilles, Andi?

It seems to be enviroment-realted... I have had it for some time
already with emerge Kde 4.5  enviroment.

The build for installed Kde enviroment (it was 4.4.1 I think) works
fine. Verified just now, by erased the build folder & watched that

It compile with TDM-GCC. I tested it yesterday.

Yes, but if I try TDM-GCC with emerged kde then it fails. And I have
no idea why, I have near-zero experience in C world. Some
lib/header/?? incorrect?

The emerge applies some huge patch to jpeg lib... Maybe I shopuld just
try to recompile it without patches applied... But I have no idea what
else I need to recompile after that?

I was able to compile it with the attached diff applied. The jconfig.h
seems to be the guilty one, it defines
    #if defined(libjpeg_EXPORTS)
        #define JPEG_EXPORT __declspec(dllexport)
    #else
        #define JPEG_EXPORT __declspec(dllimport)
    #endif

...
#define GLOBAL(type) JPEG_EXPORT type
#define EXTERN(type) JPEG_EXPORT type

Do you have compiled digiKam using MSVC or GCC ?

GCC.

But it is not about compiler. It is about how emerge builds (or
patches, I can't say for sure) the jpeglib.

One more patch, again for jpeg but jpeglossless kipi-plugin this time.
Now everything did compile fine.

Unfortunately turned out that my KDE was non-functional (something
causes run time exceptions in many programs) so I can't check out if
digikam works Ok.

Gert,

Thanks for the patch.

Please open a file in bugzilla digiKam component, with your patches
attached. I will include these fix just before 1.7.0 release.

i wil lcheck also compilation with these patch under windows, but not
now, i'm too busy

 Ususally, it's always better to use bugzilla than mailing list,
because it's more easy to follow bug entries against a mailling list
tread.

Generally ML entry is drowning in a huge messages list after 10 days.

Thanks in advance

Done, https://bugs.kde.org/show_bug.cgi?id=258600

I was 90% sure that the problem source is between the keyboard and
chair... Or at least specific to my computer.
