Hello everyone,
 I encountered an exception while cross compiling the Unidac
application for Aarch64 on Windows。
fpc & lazarus version:3.3.1 & 3.4
If using native controls, aarch64 can compile successfully, but when
using a uniquery , compilation errors occur.
What other parameters need to be set for the compilation environment？
Thanks.

It is preferable to report compiler exceptions in the bugtracker no
matter what the reason for the exception is.

Is your trunk version based on a recent version ? or is it older ?

I am not sure exactly what your target system is there ?

OS = Linux
Widget = Win32

Are you sure you need the trunk version of FPC ?  The fixes version is
very stable and trunk varies day by day.  Unless there is a specific
feature in trunk you need you might be better off using fixes.

@dbannon:
Perhaps my interpretation is wrong but from what i gathered TS is
developing on windows and trying to cross-compile (to aarch).

My interpretation, too.
Would have expected a "Build-Mode Linux" or something, specifying
THERE the correct LCL-Widgetset (GtkX, QTx)

Can you try 2 different experiments?

1. Turn off optimization when building your project (Compilation and
Linking -> Optimization level to 0)
2. Disable Debug (Debugging -> Remove all checkmarks here)

Yes, its not clear but if you look at the image posted above the OP
has TargetOS=Linux and widgetset=win32. That does not, to me, make a
lot of sense. (but when I cross compile, I do it from the command line
so don't see what Lazarus displays...)

And my other comment still seems relevant, does the same problem show
in FPC-Fixes ? Using trunk does confuse the issue, are we looking a
problem in the project or a (temporary) problem in the compiler ?

Thank you all！
I have found a solution, the website is
https://www.cnblogs.com/qiufeng2014/p/18001664
After modifying according to this plan, the compilation worked
properly.
