Please provide more information about your system, the build environment, version etc.

Compiled according to the steps, run Klayout.exe, can not open without any error

I recently had problems with missing DLL-files in #1108.
It is easiest to open klayout.exe from the MSYS terminal in this case.

[klayoutmatthias]

Well, building, running and debugging binaries takes some knowledge. I can't help with that - you need to be familiar with how DLLs are managed and how to debug DLL problems (Dependencies is my friend).

In the sources you will find a script (scripts/deploy-win-mingw.sh) which does packaging for you - provided you have installed NSIS for creating the installer. This script needs to be run from MSYS2 prompt and is finally the one I use to create the binary distributions with.

As @kongfu1994 has not yet explained what his actual problem is, I tend to close this issue.

[kongfu1994]

I use MSYS2 to build klayout,and install the packages with pacman:pacman -S make zip mingw-w64-x86_64-gcc mingw-w64-x86_64-make mingw-w64-x86_64-python3 mingw-w64-x86_64-qt5 mingw-w64-x86_64-ruby

and run this script ./scripts/deploy-win-mingw.sh -64

why cannot run compiler 'g++'

[klayoutmatthias]

Please read the documentation carefully: Either you proceed like on Linux with "build.sh" (on MSYS2 MinGW 64 shell) or you use "./scripts/deploy-win-mingw.sh". In the latter case, use a standard MSYS2 shell, not MSYS MinGW. You will also need NSIS installed and it may be required to patch the build script to point it to NSIS.

I recomment build.sh.

I just checked myself and compilation passed with "build.sh". However, I found that with g++ 12.1 from current MSYS there is a problem with the instantiation of certain objects and klayout.exe will not start. I do not know yet if that is a compiler issue and whether there is a workaround.

[klayoutmatthias]

Update: the problem isn't a KLayout issue but appears to be related to std::type_info::before which does does not indicate some type info structures as different which in fact they are. Both type infos come from different DLL's, so I assume the handling of such type infos inside gcc 12.1/MinGW is broken.

So bottom line is: for building KLayout MSYS2 with gcc 12.1 KLayout needs a patch.

[kongfu1994]

Thanks for the reply. Now, I have successfully compiled version 0.28 and version 0.27.10 with msys2 on windows10 system, but there is a common problem. After double-clicking klayout.exe, there is no response. In the task manager, the Klayout Application flashed by.

This is the log：

This is what I mean by the analysis above. The problem is rooted in the latest compiler that MSYS2 comes with. I am analysing the problem and I think I have a patch. But it takes some more testing before I can publish it.

[kongfu1994]

Please let me know when the patch is released, thanks

[klayoutmatthias]

I have published a patch which makes master and 0.27 branches build on latest MSYS2. I hope this will stay so for some more rolling MSYS updates.

I have also updated the instructions: https://www.klayout.de/build.html#build_windows_msys

Please note the part about creating a file defining the Python paths.

Thanks for the support, klayout can run normally based on the latest code
