Base64cpp

Base64 with encoding new line C++11 binary to ascii string encoder and decoder library.

Requirements

1. c++11
2. cmake
3. gcc/clang

Install googletest on macOS

cmake -G Xcode .. -DCMAKE_OSX_ARCHITECTURES="arm64;x86_64" -DCMAKE_INSTALL_PREFIX=~/Develop/local/universal
cmake --build . && cmake --build . --target=install

Build

git clone https://github.com/dnevera/base64cpp
cd ./base64cpp; mkdir build; cd ./build

# mac os M1  universal bin
cmake -DCMAKE_OSX_ARCHITECTURES=arm64;x86_64 ..
cmake --build . && cmake --build . --target=install

# or mac os Intel
cmake -DCMAKE_OSX_ARCHITECTURES=x86_64 ..
cmake --build . && cmake --build . --target=install 

Windows pkg-config

I assume here that MinGW was installed to C:\MinGW. 
There were multiple versions of the packages available, 
and in each case I just downloaded the latest version.

go to http://ftp.gnome.org/pub/gnome/binaries/win32/dependencies/
download the file pkg-config_0.26-1_win32.zip
extract the file bin/pkg-config.exe to C:\MinGW\bin
download the file gettext-runtime_0.18.1.1-2_win32.zip
extract the file bin/intl.dll to C:\MinGW\bin
go to http://ftp.gnome.org/pub/gnome/binaries/win32/glib/2.28
download the file glib_2.28.8-1_win32.zip
extract the file bin/libglib-2.0-0.dll to C:\MinGW\bin
