Microsoft Visual Studio is a popular development tool used primarily with C, C++, and C#. Visual Studio (community edition) can be downloaded for free but it requires a plugin called VisualGDB. This plugin is not free, but a fully functional evaluation version is available.

This page will help you set up Visual Studio for coding, building, and stepping through code in Inkcape.
 
= Installation =
 
# Follow all steps of guide [[Compiling Inkscape on Windows]].
# Make sure Inkcape compiles correctly using the console first.
# Install Visual Studio.
# Install VisualGDB.
# Set the Environment variables in the Windows System settings as described here: [[Compiling Inkscape on Windows]]. Do not use mingwenv.bat to set the environment variables.
 
'''Note:''' It is assumed the required packages are installed in the following directories:
* c:\mingw
* c:\devlibs
* c:\src\inkscape\trunk
 
= Create project in Visual Studio =
 
# Open Visual Studio.
# Select File->New->Project->Installed->Templates->VisualGDB->MinGW/Cygwin Project Wizard.
# For the project location, do not use a path with spaces.<br /><br />[[Image:new-project.png]]<br /><br />
# Give the project a name, and click OK.
# At the wizard, select Project Type->Import a project build with command-line tools.<br /><br />[[Image:import-project.png]]<br /><br />
# Click Next.
# Check the path to MinGW is correct.
# Click Next.
# Set the Inkscape source directory to:
#* c:\src\inkscape\trunk
# Select Import preserving directory structure.<br /><br />[[Image:import-project-settings.png]]<br /><br />
# Click Next.
# At Build Command, select Customize.
# Set Arguments to:
#* /c "c:\src\inkscape\trunk\btool.exe"
# Select OK.
# At Clean Command, select Customize.
# Set Arguments to:
#* /c "c:\src\inkscape\trunk\btool.exe" clean
# Select OK.
# At Debug Settings->Executable file to debug, browse to:
#* C:\src\inkscape\trunk\inkscape\inkscape.exe<br /><br />[[Image:build-settings.png]]<br /><br />
#Click Finish and wait for the project generation to finish.
 
'''Note:''' VisualGDB will not copy the source files to the Visual Studio project directory, so you can still use Version Control the usual way.
 
= Enable debugging =
 
In Explorer, open build.xml located in:
* c:\src\inkscape\trunk
Then look for the "T A R G E T : C O M P I L E" section, go to the <flags> section, and change<br />
  -O2
to
  -O0
 
Also add this flag:<br />
  -g
 
<br />[[Image:flags.png]]<br /><br />
 
Then search for this:<br />
  strip="true" symfile="${build}/inkscape.dbg"
And change to this:<br />
  strip="false" symfile="${build}/inkscape.dbg"
 
<br />[[Image:strip.png]]<br /><br />
 
'''Note:''' these changes will make Inkscape very slow to compile.
 
= Building Inkscape =
 
# In Visual Studio, select Build->Clean Solution.
# Then select Build->Build Solution.
# Come back later. This will take a while.
 
'''Note:''' The compiler will seem to be stuck at this for a while, but that is normal:
  1>  --- compile / cc
 
= Stepping through code =
 
# In Visual Studio, go to Solution Explorer->Inkscape->Source Files->src->main.cpp, and set a breakpoint here:<br /><br />[[Image:breakpoint.png]]<br /><br />
# Select Debug->Start Debugging With GDB.
# If you get a "GDB command timeout" window, be patient.
# Inkscape will stop at the breakpoint. Happy debugging.
 
= Trouble shooting =
 
In case Visual Studio cannot break at a certain breakpoint (most likely no debugging symbols present), you can diagnose breakpoint problems using the VisualGDB diagnose tool:
