I really don't get why that lib doesn't link, can anybody give an idea?

You use -L tell give the linker a DIRECTORTY to look in, the -l for the lib:
So you want -L"app/headers/libsodium-win64/lib/" -lsodium

#

Also for the love of god learn how to use cmake or use VS2022, save this massive command line

wicked flint
#

I tried -L"app/headers/libsodium-win64/lib" -lsodium too, same output

Try the absolute path

GPT Suggested to check through the libsodium.a it self for the function with the strings command. It is present there.

# wicked flint It is there. So the the .a file should be the right one. Have other idea?

Try this, it should work I am not sure why it wouldn't:

g++ -shared -fPIC \
    -I"C:/WEB/NChat/app/headers" \
    -I"C:/WEB/NChat/app/headers/libsodium-win64/include" \
    -I"C:/cpp/global_libs/mariadb/install/include/mariadb" \
    "C:/WEB/NChat/app/handlers/user.cpp" \
    -L"C:/WEB/NChat/app/headers/libsodium-win64/lib" \
    -L"C:/cpp/global_libs/mariadb/install/lib/mariadb" \
    -lmariadbclient \
    -lws2_32 -lsecur32 -lcrypt32 -ladvapi32 -lshlwapi -lbcrypt \
    -lsodium \
    -o "C:/WEB/NChat/app/handlers/user.dll"
#

Otherwise you could do

nm libsodium.a | grep crypto_pwhash_str

How very strange try forcing the lib in there

g++ -shared -fPIC \
    -I"C:/WEB/NChat/app/headers" \
    -I"C:/WEB/NChat/app/headers/libsodium-win64/include" \
    -I"C:/cpp/global_libs/mariadb/install/include/mariadb" \
    "C:/WEB/NChat/app/handlers/user.cpp" \
    -L"C:/cpp/global_libs/mariadb/install/lib/mariadb" \
    -lmariadbclient \
    -lws2_32 -lsecur32 -lcrypt32 -ladvapi32 -lshlwapi -lbcrypt \
    "C:/WEB/NChat/app/headers/libsodium-win64/lib/libsodium.a" \
    -o "C:/WEB/NChat/app/handlers/user.dll"

Still nothing...

Where is the issue.

unique siren
#

Unless g++ is having issues with that lib maybe, I am really not sure, if I were you and annoying as this is, I would just use WSL and install everything through the package maanger

#

Then it will save all this manual bollocks

Anywho, you should really avoid the pain which is non MSVC on windows, so on windows just stick with VS2022 and MSVC, it is the easiest options.
If you want to use g++ just use wsl where it is properly supported and you can get all the packages easily on it
Windows does not work well with these packages

wicked flint
#

I dont even have gcc on my pc

unique siren
#

Well you must have, when you install clang it doesn't install gcc

#

The ONLY place where g++ is actually clang is on apple mac where they hide it

C:\WEB\NChat>g++ --version

Try: clang++ --target=x86_64-w64-windows-gnu

#

So:

clang++ --target=x86_64-w64-windows-gnu -shared -fPIC \
    -I"C:/WEB/NChat/app/headers" \
    -I"C:/WEB/NChat/app/headers/libsodium-win64/include" \
    -I"C:/cpp/global_libs/mariadb/install/include/mariadb" \
    "C:/WEB/NChat/app/handlers/user.cpp" \
    -L"C:/WEB/NChat/app/headers/libsodium-win64/lib" \
    -L"C:/cpp/global_libs/mariadb/install/lib/mariadb" \
    -lmariadbclient \
    -lws2_32 -lsecur32 -lcrypt32 -ladvapi32 -lshlwapi -lbcrypt \
    -lsodium \
    -o "C:/WEB/NChat/app/handlers/user.dll"
#

And then delete this weird ass compiler and install the proper 64 bit one

wicked flint
#

Yeah... Now I get the error linking the maridb connector, probably because it was built using the 32 bit target. I think I am fine from now, will try to fix further my self. thank you!

unique siren
#

Honestly, stop fooling around with all these manual paths, use WSL and it will install all the correct libs for you and the correct compiler

#

MinGW is dogshit
