Some error with ssize_t

[JeremyGiner]

I'm trying to compile a simple test program using dlls with cygwin and gcc and i get the following error :

Error: Error while running command env g++ "-IC:/workspace/haxe_test/New Project/build_cpp/obj/cygwin64/pch/haxe" -Iinclude -IC:\cygwin64\lib\gcc720_dll\include -IC:\cygwin64\lib\gcc720_dll\lib\vc_dll\mswu -IC:/HaxeToolkit/haxe/lib/hxWidgets/1,0,0..\include -DUNICODE -D_UNICODE -DwxMSVC_VERISON_AUTO -DWIN32 -DWXMSW -DWX__=1 -DWXUSINGDLL -c -O2 -DHX_LINUX -DHXCPP_M64 -DHXCPP_VISIT_ALLOCS -DHXCPP_API_LEVEL=331 -m64 -IC:/HaxeToolkit/haxe/lib/hxcpp/4,0,4/include -c -DwxUSE_LIBMSPACK -O2 -DHX_LINUX -DHXCPP_M64 -DHXCPP_VISIT_ALLOCS -DHXCPP_API_LEVEL=331 -m64 -IC:/HaxeToolkit/haxe/lib/hxcpp/4,0,4/include -x c++ -frtti -frtti ./src/wx/widgets/_FontWeight/FontWeightImpl.cpp "-oC:/workspace/haxe_test/New Project/build_cpp/obj/cygwin64/1fa3da40_FontWeightImpl.o"

I'm not really good with c++ stuff but it seems like hxcpp and wxWidget doesn't like each other. Any idea on what would be the problem?

[ianharrigan]

Hmm, what version of haxe, hxcpp, wx? Also, can you zip up the test app? Does this work with VC++? (ive never tried with gcc on windows but worked on OSX / linux)

[JeremyGiner]

haxe 3.4.0 hxcpp (Haxe C++ Runtime Support) (4.0.4) wxWidgets 3.1.1

Main.hx :

package;

import hx.widgets.*;

class Main {
    public static function main() {
        var app = new App();
        app.init();

        var frame:Frame = new Frame(null, "hxWidgets");

        var taskBarIcon = new TaskBarIcon();
        taskBarIcon.setBitmap(Bitmap.fromHaxeResource("haxe-logo-tiny.png"), "Some tooltip");

        var platform:PlatformInfo  = new PlatformInfo();
        if (platform.isWindows) {
            frame.backgroundColour = 0xFFFFFF;
        }

        //frame.menuBar = buildMenu();
        frame.sizer = new BoxSizer(Orientation.VERTICAL);
        frame.resize(800, 600);

        var imageList:ImageList = new ImageList(16, 16);
        imageList.add(Bitmap.fromHaxeResource("ui-check-boxes-series.png"));
        imageList.add(Bitmap.fromHaxeResource("layer-shape-line.png"));
        imageList.add(Bitmap.fromHaxeResource("ui-scroll-pane-list.png"));
        imageList.add(Bitmap.fromHaxeResource("information-button.png"));
        imageList.add(Bitmap.fromHaxeResource("application-dialog.png"));
        imageList.add(Bitmap.fromHaxeResource("globe-green.png"));

        var tabs:Notebook = new Notebook(frame);
        if (platform.isMac) {
            tabs.allowIcons = false;
        }
        if (platform.isWindows) {
            tabs.padding = new Size(6, 6);
        }
        tabs.imageList = imageList;

        frame.sizer.add(tabs, 3, Stretch.EXPAND | Direction.ALL, 10);

        frame.sizer.addSpacer(5);

        frame.layout();
        frame.show();

        app.run();
    app.exit();
    }
}

I don't know about VC++

[JeremyGiner]

My .hxcpp_config is quite wierd, i kind of copy-pasted bits of code from everywhere trying to fix some other errors i was having. I assume that if the error come from somewhere it might come from this config.

.hxcpp_config :

have you tried to compile this: https://github.com/haxeui/hxWidgets/tree/master/samples/00-Showcase

IIRC correct this compiles fine via the .hxml files on all OS's i tested.

[JeremyGiner]

Try to compile the project as is, it gave me the "no compiler define for target" which i fixed by adding my usual flag : -D cygwin -D windows -D HXCPP_VERBOSE=1 -D HXCPP_M64 -D WXWIN=C:\cygwin64\lib\gcc720_dll

And then it asked for a missing wx/setup.h file, which apparently a "master" copy exist in include/wx/msw/wx/setup.h so i just copied the file to include/wx. And now i have the error : #error "This file should only be included when using Microsoft Visual C++"

I'm just going to give up this is not worth the effort. My config of hxcpp is most likely the source of all that, so i'm just going to close the issue, thank for your help anyway.

[ianharrigan]

How come you dont want to use MSVC on windows? Also, how did you install haxe under cygwin? I presume you are using the cygwin terminal? Have you tried http://tdm-gcc.tdragon.net/ (ie, just gcc withut the cygwin env)?

Main problem is its hard to know how your system(s) are setup so hard to reproduce.
