wxWidgets libjpeg problem

[Knx]

I've compiled wxWidgets 2.8.3.

But when I try to compile a wx project on C::B I get a lot of errors

Code

:: === test, Debug ===
:C:\CodeBlocks\wx\build\msw\..\..\src\common\imagjpeg.cpp:205: undefined reference to `jpeg_resync_to_restart'
:C:\CodeBlocks\wx\build\msw\..\..\src\common\imagjpeg.cpp:238: undefined reference to `jpeg_std_error'
:C:\CodeBlocks\wx\build\msw\..\..\src\common\imagjpeg.cpp:252: undefined reference to `jpeg_destroy_decompress'
:C:\CodeBlocks\wx\build\msw\..\..\src\common\imagjpeg.cpp:257: undefined reference to `jpeg_CreateDecompress'
...

Will this patch work?
I found it on wiki

How I "install" it?

[Biplab]

Most probably, the patch will not work.

Possible reason of that error is missing jpeg headers.

Are you compiling wxWidgets with C::B? Or you're compiling a wxWidgets project?

[Knx]

I've already compiled wxWidgets

Code

mingw32-make -f makefile.gcc

It took 10minutes+

I'm trying to compile a new wxWidgets project inside C::B.

No need for a patch, just add "wxjpeg" to your link libraries. Since you didn't specify "MONOLITHIC=1" when building wxWidgets, the default multilib version was built. When using the multilib version of wxWidgets, most programs need wxbase at least and usually the utility libraries (wxpng, wxtiff, wxjpeg, wxzlib, wxexpat, wxregex) and platform libraries as well. (For Windows, wxmsw_core, wxmsw_adv, and the rest).

What's wxjpeg?

If I compile with MONOLITHIC=1 I won't need to do anything right? I'll try it then.

What's wxjpeg?

wxjpeg is the name of the library containing the jpg stuff.
The filename should be (under windows) libwxjpeg.a and (debug build) libwxjpegd.a.

If I compile with MONOLITHIC=1 I won't need to do anything right? I'll try it then.

No, the image manipulation libs aren't build into the monolithic library. Just go to "Project"->"Build options"->select "Linker Settings"->click "Add" under "Link Libraries" and type in "wxjpeg".

[TDragon]

No, the image manipulation libs aren't build into the monolithic library.

The image manipulation libs aren't built into the static (default) monolithic library, true. A monolithic DLL build (SHARED=1) already includes them, however.

Ah, good to know

Compiled with

Code

mingw32-make -f makefile.gcc

Adding libraries

Code

ld.exe:: cannot find -lwxmsw28d_dbgrid
:: === Build finished: 1 errors, 0 warnings ===

When I compile with

Code

mingw32-make -f makefile.gcc SHARED=1 MONOLITHIC=1

It says that can't find "wx/setup.h"

[stahta01]

Verify that these files exist in your wxWidgets folder.

include\wx\msw\setup0.h
include\wx\msw\setup.h

Note: If include\wx\msw\setup.h is missing copy include\wx\msw\setup0.h to include\wx\msw\setup.h

Try below and see if it works for you, note it assumes MinGW is installed in C:\MinGW and that you are in your wxWidgets folder.

Code

CD build\msw
SET PATH=C:\MinGW\bin;C:\MinGW\mingw32\bin
mingw32-make -f makefile.gcc  SHARED=1 MONOLITHIC=1 clean
mingw32-make -f makefile.gcc  SHARED=1 MONOLITHIC=1

Yes, there is setup.h in that folder.
I've compiled as you said.

When I'm creating a wxW project It says:



also for release.

Compiling without anything it works. (mingw32-make -f makefile.gcc)

Turn ON FULL Compiler Logging and post the commands that have the error.

What directory are you using as the Specified wxWidgets Directory that does not have the setup.h?

Tim S

[Biplab]

Wizard sets include directory for setup.h file under lib dir. E.g., if you use the following command to compile wx:

Code

mingw32-make -f makefile.gcc

Then the setup.h file is copied to <wxWidgets_dir>\lib\gcc_lib\mswd\wx directory. Wizard adds this directory to the project file and the actual contents of this directory depends upon your choices.

So if you get such error that "setup.h not found", then probable reason is You're using wrong settings in the wizard.

The warning message is shown for a purpose.

IMO, you didn't change the options which was leading C::B to search for some critical libraries in a wrong directory. It tells you that particular target will throw error during compiling. It may come due to 1) the particular configuration you're trying to use doesn't exist in your system, 2) selection of wrong options in wizard.
