# ===================================================================

# Below are details for compiling on Windows and Linux
# by default only an example g2log 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

# 2012-05-29: justthread is no longer necessary on Windows (vs2011) and
#             linux (gcc4.7.1)


# WINDOWS == README: Example how to setup environment + running an example
# 1. please use the "Visual Studio Command Prompt)"
# 2. from the g2log folder
#    mkdir build
#    cd build;
# 3. cmake -DCMAKE_BUILD_TYPE=Release -G "Visual Studio 11" ..
#              the "Visual Studio 11" .. does not require just::thread!
# 4. msbuild g2log_by_kjellkod.sln /p:Configuration=Release
# 5. Release\g2log-FATAL-example.exe
#
#
# . LINUX:To try this out from folder g2log:
#    mkdir build
#    cd build
#    cmake ..    # create makefiles in g2log/build directory
#    make    # link active_object, g2log and example code to get an "example" executable
#     ./g2log-FATAL-example
