Compile issue on Windows with Mingw on Open62541 version >=1.4.0

[g-tardy]

Description

I was not able to compile correctly Open62541 on MingW64 under Windows. This starting with Open62541 version 1.4.0

Background Information / Reproduction Steps

The compile error does not occur on Open62541 version < 1.4.0

Notes for cmake options: I compiled mbdetls in a specific subfolder to avoid having it installed on dev machine.
I had to

Used CMake options:

-G "MinGW Makefiles"
-D CMAKE_BUILD_TYPE=Release
-DBUILD_SHARED_LIBS=ON
-DOPEN62541_VERSION="v1.4.5"
-DUA_ENABLE_ENCRYPTION=MBEDTLS -DMBEDTLS_INCLUDE_DIRS="..\mbedtls\include"
-DMBEDTLS_LIBRARY="..\mbedtls\build\library\libmbedtls.a"
-DMBEDX509_LIBRARY="..\mbedtls\build\library\libmbedx509.a"
-DMBEDCRYPTO_LIBRARY="..\mbedtls\build\library\libmbedcrypto.a"

Correction found:

To bypass the compile issue, I had to include the following CMake option:

-DCMAKE_C_FLAGS="-D_WIN32_WINNT=0x0600"

This may be helpful to anyone who encountered the same issue as me...

Code suggestion:

It may be good to include the following code (or equivalent) in the config.h.in:

#ifdef _WIN32
# ifndef _WIN32_WINNT
#  define _WIN32_WINNT 0x0600
# endif
#endif

Checklist

• open62541 Version (release number or git tag): 1.4.0 and above
• Other OPC UA SDKs used (client or server): Both

After investigation, it seems that ua_architecture.h was modified with this commit: 16f68d8

@CHN-STUDENT
I do not think your issue is related to what I mentioned...

But looking at your log, it really sounds like what mentioned maleadt on this github thread:
JuliaLang/julia#51740

Please check your gcc version, and try using version 12:
JuliaLang/julia#51740 (comment)
