Steps taken

  1. nimble init project-name && cd project-name
  2. nimble install wxnim
  3. echo 'requires "wxnim#head"' >> project-name.nims

  4. nvim src/project-name.nim and write

    import wxnim/[wx, genui]

{.experimental: "implicitDeref".}

{.emit: "#include <wx/spinctrl.h>".}

var cbChoices = @["Combobox 1", "Combobox 2", "Combobox 3"]

var
  spinner: ptr WxSpinCtrl
  slider: ptr WxSlider
  gauge: ptr WxGauge

proc spinnerCallback(e: varWxSpinEvent) {.cdecl.} =
  let val = e.getPosition()
  spinner.setValue(val)
  gauge.setVal(val)

genui:
  mainFrame % Frame(title = "Hello world"):
    Panel | Boxsizer(orient = wxHorizontal):
      StaticBox(label = "Basic controls")[proportion = 1] | StaticBoxSizer(orient = wxVertical):
        Button: "Button"

    CheckBox: "Checkbox"
    TextCtrl(value = "Entry")
    StaticText: "Label"
  5. nvim config.nims and write 
    --define:"wxWidgetsPath:wxwidgets-mingw"
--define:"mingw"
  6. Download the headers and libraries from https://www.wxwidgets.org/downloads/ under the MinGW-w64 8.1 label for x86_64. The headers from https://github.com/wxWidgets/wxWidgets/releases/download/v3.2.5/wxWidgets-3.2.5-headers.7z and the libraries from https://github.com/wxWidgets/wxWidgets/releases/download/v3.2.5/wxMSW-3.2.5_gcc810_x64_ReleaseDLL.7z
  7. mkdir wxwidgets-mingw and unzip the downloaded archives into that directory.

  8. nimble build

Sorry for not getting back to you sooner, been busy lately. Just pushed a version to fix some issues with Nim 2.0.6. However I see you use 2.1.1 which is an unstable development version. I can't reproduce your errors with the stable version, so I have to assume it's a bug in whatever development version you where using. I also tried your code and apart from some typos it also seems to have some logic errors. Below is my updated version which works fine:

import wxnim/[wx, genui]

var cbChoices = @["Combobox 1", "Combobox 2", "Combobox 3"]

var
  spinner: ptr WxSpinCtrl
  slider: ptr WxSlider
  gauge: ptr WxGauge

proc spinnerCallback(e: var WxSpinEvent) {.cdecl.} =
  let val = e.getPosition()
  spinner.setValue(val)
  gauge.setValue(val)

genui:
  mainFrame % Frame(title = "Hello world") | Boxsizer(orient = wxVertical):
    Panel | Boxsizer(orient = wxHorizontal):
      StaticBox(label = "Basic controls")[proportion = 1] | StaticBoxSizer(orient = wxVertical):
        Button: "Button"

    CheckBox: "Checkbox"
    TextCtrl(value = "Entry")
    StaticText: "Label"

mainFrame.show()
runMainLoop()

The code sample is a subset of the example here https://github.com/PMunch/wxnim/blob/master/examples/genuimacro/controlgallery.nim

PMunch commented 1 week ago

Yes I recognized the code. But when I now full the latest version of this repo it builds fine with the latest Nim version. So I'm unable to reproduce your issue. Did you try to upgrade to the latest stable Nim version and the latest version of wxnim? Keep in mind that old versions still in .nimble/pkgs might override those in .nimble/pkgs2, so best delete the entire old package cache.

I have only ~/.nimble/pkgs2. Are you trying to cross-compile it from linux using mingw toolchain?
