Subject: Building x32 libraries on x64 windows machine

Hi All,

I trying to build openssl 3.0.8  to generate x32/win32 libraries and header files.
I used the following steps:
Opened the x86 Native Tools Command Prompt  (Sets the environment to use 32-bit, x86-native tools to build 32-bit, x86-native code)
perl Configure --debug --openssldir="C:\OpenSSLW32\CommonFiles\SSL" --prefix=C:\OpenSSLW32 VC-WIN32
nmake

However, I get the following error.

       cmd /C ""cl" /Zs /showIncludes  /Zi /Fdossl_static.pdb /Gs0 /GF /Gy /MDd /W3 /wd4090 /nologo /Od -I"." -I"include" -I"apps\include" -D"L_ENDIAN" -D"OPENSSL_PIC" -D"OPENSSLDIR=\"C:\\OpenSSLW32\\CommonFiles\\SSL\"" -D"ENGINESDIR=\"C:\\OpenSSLW32\\lib\\engines-3\"" -D"MODULESDIR=\"C:\\OpenSSLW32\\lib\\ossl-modules\"" -D"OPENSSL_BUILDING_OPENSSL" -D"OPENSSL_SYS_WIN32" -D"WIN32_LEAN_AND_MEAN" -D"UNICODE" -D"_UNICODE" -D"_CRT_SECURE_NO_DEPRECATE" -D"_WINSOCK_DEPRECATED_NO_WARNINGS" -D"DEBUG" -D"_DEBUG"   "apps\lib\tlssrp_depr.c" > apps\lib\libapps-lib-tlssrp_depr.d 2>&1"
        "lib" /nologo /out:apps\libapps.lib @C:\Users\user\AppData\Local\Temp\1\nmB79E.tmp
apps\lib\libapps-lib-fmt.obj : fatal error LNK1112: module machine type 'x64' conflicts with target machine type 'x86'
NMAKE : fatal error U1077: '"lib" /nologo /out:apps\libapps.lib @C:\Users\user\AppData\Local\Temp\1\nmB79E.tmp' : return code '0x458'
Stop.
NMAKE : fatal error U1077: '"C:\Program Files\Microsoft Visual Studio\2022\Professional\VC\Tools\MSVC\14.38.33130\bin\HostX86\x86\nmake.exe" /                   _build_sw' : return code '0x2'
Stop.

I also tried the x64_x86 Cross Tools Command Prompt - Sets the environment to use 64-bit, x64-native tools to build 32-bit, x86-native code.  That gave the same error.

I would have expected that setup to be able to build the win32 version of the objects and libraries.
What did I miss or is this not supported?
Thanks.

P.S.  This all worked fine when I setup to build x64.  Not errors and got libs and objects for x64.
