GTK in Code:Blocks (Windows 10)

Hi there,

After a serious Windows 10 crash, I had to re-format my disk and to re-install everything on my computer, but I remain unable to re-install GTK on Code:Blocks.

The version of Code:Blocks is the last one available (20.03) but I want to install the 2.24 version of GTK.

GTK is apparently correctly installed (after pkg-config; and gtk-demo works fine). I've correctly declared (I think) in Code:Blocks directories and libraries. However, I remain unable to compile my codes, and get the following error messages:

--- Quote ---ld.exe||cannot find -lgtk-win32-2.0| ld.exe||cannot find-lgobject-2.0| ld.exe||cannot find -lglib-2.0|
--- End quote ---

These libraries are in gtk/lib, which is declared in Code:Blocks.

This is now driving me crazy.. Especially since I've done that several times before without problems..

Thanks for any help on that & cheers,

Eric.

and the path where you installed GTK.

GTK is installed here: C:\Program Files (x86)\CodeBlocks\MinGW\gtk

Thanks in advance for your help!

The "skipping incompatible library" error is shown because you are trying to link with libraries created with other compilers. The .lib are probably from Visual Studio and the .dll.a from other version or GCC (or the same version with different number of bits, 64 vs 32). You must create those libs with the same compiler and options used when compiling your program.

Thanks, but I do not see how this can be the explanation.

First of all, I'm not the one that compiled the GTK library. I took binaries already available for Windows. Second, as I said, I already installed this same GTK library on the same computer, with the same Windows version before, without any problem. So, I do not think the problem is coming from the library.

The only difference between what I did before, on the same machine, and what I'm trying to do now, is that I now use a new version (updated) of Code:Blocks, that maybe comes with a new version of gcc. For example, the GTK library is in 32 bits (I assume this is what the "win32" means), while I indeed install a 64 bits version of Code:Blocks. Can this be a possible explanation of the problem I have?

In all cases, thanks for your time and help on this.

Eric.
