cross compiling for windows issue

[GeorgeNs]

Hi,and sorry of i bug you again about cross on linux.
I tried to cross compile the fat1 expecting to be easy without so many issues-configurations and i could build it succesfully using the mingw32 static.posix version of mxe enviroment. I tested it on windows (10) with ardour and the gui opens.. everything works. However,something strange happens if i close the gui window and go to make a recording,ardour crashes. That happens only if i close the plugin's gui window . If i keep it open there is no crash.
I am wondering what can be the issue since i didn't get any warning during building,can be the pthread win32 libs or something from the robtk package windows ui directories(?)

Thanks

Without a backtrace, I can only guess.. probably some static d'tor in glib. or, perhaps a symbol conflict between ardour's DLL (pango, cairo, glib,..) and the plugin's if the plugin does not hide symbols of libs it uses and the lib is unloaded.

I spent quite a long time to make robtk and this plugin work reliably cross-platform and test the binary provided at https://x42-plugins.com/x42/x42-eq to work and it's not very likely that is is an issue with the plugin's or robtk/pugl code.

You are right,i tried the binaries from your site and there is no issue. fat1 looks has similar structure but in a much simpler form.However, i can't find why crashes ardour,is there any similar command on windows like ldd?i have to search..maybe dumpbin from vs?

By the way, i gave a try with the shared version of mingw and i tested,i don't get the same problem,ardour won't crash once i close window and go to record.However,maybe i will get other issues later that i can't see now...

about glib reconfiguration:
in glib i found only:
$as_echo "#define _GLIB_EXTERN attribute((visibility("default"))) __declspec(dllexport) extern" >>confdefs.h

I deleted __declspec(dllexport) then should i undefine DLL_EXPORT inside quotes or do unset DLL_EXPORT after that line?
Thanks

Yep, that sounds about right, same as recently discussed with x-compiling setBfree. As for the details, I'd have to look.

I tried to recompile it changing that line so:
$as_echo "#define _GLIB_EXTERN attribute((visibility("default"))) #undefine DLL_EXPORT extern" >>confdefs.h

Then i get many errors.Here are the first of them:
