windows 32 bit OpenAI API Chatbot in C

[ron77]

OK this code is in C it depends on using libraries such as libcurl and libcjson and zlib
I compiled it with mingw32 32bit and it works without TTS just text on the screen of the terminal (cmd) command prompt...

it works on windows 11

you compile it like so:

gcc openai_chatbot.c -o openai_chatbot.exe -lwinhttp

now about the libcurl and libcjson and zlib you will need git to clone the source files and build from source and install:

git clone https://github.com/DaveGamble/cJSON.git
cd cJSON
mkdir build
cd build
cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW -DENABLE_CJSON_TEST=Off -DENABLE_CJSON_UTILS=Off
mingw32-make
mingw32-make install

git clone https://github.com/madler/zlib.git
cd zlib
mkdir build
cd build
cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW
mingw32-make
mingw32-make install

cd ../..
git clone https://github.com/curl/curl.git
cd curl
mkdir build
cd build
cmake .. -G "MinGW Makefiles" -DCMAKE_INSTALL_PREFIX=C:/MinGW -DBUILD_CURL_EXE=OFF -DBUILD_SHARED_LIBS=OFF -DCURL_STATICLIB=ON
mingw32-make
mingw32-make install

Make sure to replace C:/MinGW with the actual path to your MinGW installation.
