Γιατί δεν μπορώ να linkαρω το applink.c όταν κάνω crossbuild σε linux windows app 32bit?

[PC_MAGAS]

Προσπαθώ να συνδέσω την βιβλιοθήκη που έκτησα  σε linux Μέσω Mingw-32 comiler:

sudo apt-get install gcc-mingw-w64-x86-64 g++-mingw-w64-x86-64 wine64
sudo apt-get install g++-mingw-w64-i686 g++-mingw-w64-i686
wget https://www.openssl.org/source/openssl-1.1.1q.tar.gz
tar -xvf openssl-1.1.1q.tar.gz
cd ./openssl-1.1.1q
./Configure enable-tls1_3 no-asm no-async no-dso no-engine no-shared --cross-compile-prefix=i686-w64-mingw32- --prefix=/usr/bin/i686-w64-mingw32-gcc mingw
make -j16

Σε μια εφαρμογή που xρησιμοποιεί winsock (αρχείο main.c):

με την εντολή:

LANG=C i686-w64-mingw32-gcc main.c -lws2_32 -Iopenssl-1.1.1q/include -o main.exe

Αλλά αδυνατώ να συνδέσω το αρχείο openssl/applink.c. Εχετε καμια ιδέα πως θα το Linkάρω;

main.cpp:10:10: fatal error: openssl/applink.c: No such file or directory
 #include <openssl/applink.c>
          ^~~~~~~~~~~~~~~~~~~
compilation terminated.

Υπάρχει όντως το αρχείο στον φάκελο που θα έπρεπε να βρίσκεται;

Από Google search:

openssl/applink.c is required for OpenSSL to work on Windows, when compiled by MSVC (Miscrosoft Visual Studio Compiler). It is included in the Windows version of OpenSSL from 1.1.0 and above, but is excluded on OpenSSL for Mac, Linux or MinGW

I the end απλά ήθελε να κάνω:

make install

Μετά έπρεπε εκτελέσω τα παρακάτω: https://stackoverflow.com/a/72984554/4706711

Η Openssl 1.1.0.g απλά ορίζει μυστήρια διαδρομή για linux όταν κάνεις `make install`.

Indeed δεν χρειάζετε επειδή κάνω build με mingw.
