theres much more.. but it's too big
i did these project before and i know that it's working.. but maybe, now, the problem is the Linker Options.
what you can advice me?

[stahta01]

My guess is you are mixing two compiler toolchains together; that can result in weird errors like you got.
Link to how to use code tags https://wiki.codeblocks.org/index.php?title=FAQ-Compiling_%28general%29#Q:_How_do_I_report_a_compilation_problem_on_the_forums.3F

Edit: The reason I think two tool chains are being used.

Code

C:\Program Files (x86)\CodeBlocks\MinGW\i686-w64-mingw32\lib

Code

 "..\..\..\..\..\Program Files\CodeBlocks\mingw32\i686-w64-mingw32\lib\libwinmm.a"

Decide which toolchain you wish to use; then only use that one!

Re-read my last post, I edited it.

Tim S.

[cambalinho]

yes... was on Project Build Options... i change it. thanks for that.
but the same errors\warnings continues

[stahta01]

Please post the build log with at least the first error and up to three warning above it and post the next two lines down[below the error].
You cutting up the build log makes it impossible to help you!

Tim S.

[cambalinho]

heres the log and messages on zip file and the H file.

[stahta01]

You have to stop using libraries from two different toolchains.

Tim S.

[stahta01]

Is the g++.exe from 64 or 32 bit mingw compiler?

Are you using an 64 bit or 32 bit CB?

Tim S.

[cambalinho]

both 32 bits.

[cambalinho]

i found some errors that i didn't notice: the image class, for exemple, is redefinided.
i can fix these

[stahta01]

Please try using this way to do static library usage

Code

$(TARGET_COMPILER_DIR)/i686-w64-mingw32/lib/libmsimg32.a

Instead of doing this way!

Code

"..\..\..\..\..\Program Files\CodeBlocks\mingw32\i686-w64-mingw32\lib\libmsimg32.a"

You need to use *only* a single toolchain!!!!

Tim S.

[stahta01]

i found some errors that i didn't notice: the image class, for exemple, is redefinided.

Yes, fix those errors and then try my prior post suggestion.

Tim S.

[cambalinho]

done!!
now lets go to another error:

Code

a.KeyDown=[](int key, int repeat)
    {
        if(CombinationKeys({'A','S'},{'W'},{'R','T'}, {'O','P'})==true)
        {
            a.Text="hello world";
            MessageBox(NULL,"hi", "hello",MB_OK);
        }

        if(key==VK_ESCAPE)
            End();

    };

'a' it's from 'form' class:

Code

//KeyBoard events:
        event(KeyDown, (int *Key, int repeat)) = [](int *Key, int repeat) {;};

from:

Code

#define event(EventName, ... ) std::function<void(__VA_ARGS__ )> EventName

now i get the error here:

Code

a.KeyDown=[](int key, int repeat)
    {
        if(CombinationKeys({'A','S'},{'W'},{'R','T'}, {'O','P'})==true)
        {
            a.Text="hello world";
            MessageBox(NULL,"hi", "hello",MB_OK);
        }

        if(key==VK_ESCAPE)
            End();

    };

"C:\Users\Utilizador\Documents\CodeBlocks\classcontrols\main.cpp|73|error: no match for 'operator=' (operand types are 'std::function<void(int*, int)>' and 'WinMain(HINSTANCE, HINSTANCE, LPSTR, int)::<lambda(int, int)>')|"
what i'm doing wrong?

I can not help you with that; I have forgotten more C++ than I remember.

And, that is a C++ type problem, my skill is fixing build issues.

I still have problems with the idea that others can not understand build errors that are simple to me.

Tim S.

[cambalinho]

yes.. now it's fixed:

Code

a.KeyDown=[](int *key, int repeat)
    {
        if(CombinationKeys({'A','S'},{'W'},{'R','T'}, {'O','P'})==true)
        {
            a.Text="hello world";
            MessageBox(NULL,"hi", "hello",MB_OK);
        }

        if(*key==VK_ESCAPE)
            End();

    };

it's a pointer.. that's my error
now i have more 2 Warnings:
1)

Code

if (inst->clrBackColor==-1)

"warning: comparison of integer expressions of different signedness: 'color' {aka 'long unsigned int'} and 'int' [-Wsign-compare]|"
i use '-1' for transparent... can i avoid these warning?

2)

Code

hwnd = CreateWindowEx(NULL, classname, strCaption.c_str(),WS_OVERLAPPEDWINDOW | WS_CLIPCHILDREN,
                                  CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, parent, NULL, mod, this);

"warning: passing NULL to non-pointer argument 1 of 'HWND__* CreateWindowExA(DWORD, LPCSTR, LPCSTR, DWORD, int, int, int, int, HWND, HMENU, HINSTANCE, LPVOID)' [-Wconversion-null]|"
i don't know avoid these 2 warnings
