# Below are details for compiling on Windows and Linux
# by default only an example g3log binary is created
# the performance and unit tests creation can be enabled by switching their
# OPTIONs from OFF to ON --- See below at around line 110

# === WINDOWS ===
# Example for: Visual Studio 2013 (earlier should work too)
# 1. please use the "Visual Studio Command Prompt 12 (2013)"
# 2. from the g3log folder
#    mkdir build
#    cd build;
# 3. cmake -DCMAKE_BUILD_TYPE=Release -G "Visual Studio XXX" ..
#     (cmake -DCMAKE_BUILD_TYPE=Release -G "Visual Studio 12")
#    (XXX is the Visual Studio version you are running)
# 4. msbuild g3log.sln /p:Configuration=Release
#
# Try to run an example, such as:
# 5. Release\g3log-FATAL-contract.exe
#
#

# ===   LINUX: === To try this out from folder g3log:
#    mkdir build
#    cd build
# >> create makefiles in g3log/build directory
#   cmake -DCMAKE_BUILD_TYPE=Release ..
#    make -jN   (where N stands for number of cores you want to utilize)
#
#
#
# ===  Clang on Linux ===
#   From g3log
#   mkdir build && cd build
#   cmake -DCMAKE_CXX_COMPILER=clang++ ..
#   if you want to double-check settings:   "VERBOSE=1 make"
#   otherwise just run:   "make -j"
