MonoCov - Building on OS-X

My answer from Stackoverflow on compiling MonoCov on OS-X and Mono 4.0.x

# Clone the MonoCov repo
git clone MonoCov
cd MonoCov
# A really old version of cecil and it not available as a nuget
curl -o
# Make sure configure can find the Mono.Option source file
export PKG_CONFIG_PATH=/Library/Frameworks/Mono.framework/Versions/4.0.1/lib:/Library/Frameworks/Mono.framework/Versions/4.0.1/lib/pkgconfig:$PKG_CONFIG_PATH
# Config to install to users home dir
./configure --cecil=$PWD/monocov/cecil-0.6/Mono.Cecil.dll --prefix $HOME/monocov
# Fix Makefile, gmcs no longer exists under Mono 4.x and Makefile is hard coded
sed -i.bak s/gmcs/mcs/g Makefile
# Pass -m32 to make since OS-X Mono framework is still 32-bit
CC="cc -m32" make
# Install does not properly create bin dir, do it before the first install
mkdir $HOME/monocov/bin
# Install..
make install

Compile a test app and test MonoCov:

// Save this to a file named Program.cs
using System;
namespace Foobar
    class MainClass
        public static void Main (string[] args)
            Console.WriteLine ("Hello MonoCov");

Profile a Mono (.Net) application

# Compile a sample app
mcs Program.cs
# Update path to include MonoCov so mono can load it as a profiler
export PATH=$HOME/monocov:$PATH
mono --debug --profile=monocov Program.exe

Launch the MonoCov GUI

# GUI Framework DllNotFoundException fix (if needed)
export DYLD_FALLBACK_LIBRARY_PATH="/Library/Frameworks/Mono.framework/Versions/Current/lib:/usr/local/lib:/usr/lib"
# Update path to include MonoCov
export PATH=$HOME/monocov/bin:$PATH
