The build system used in Microsoft Visual Studio 2010 is based on MSBUILD, Microsoft’s dedicated build management tool, a change that requires that external tools are integrated into the development environment in a new way. VSYASM has been developed to facilitate Yasm integration with Visual Studio 2010 in a robust and efficient manner. The main difference between VSYASM and other versions is that it is capable of assembling multiple source code files given on a single command line.
When assembling a single file VSYASM behaves in the same way as the normal yasm tool. The only change in this case is that VSYASM doesn’t offer the pre-process only mode.
If however the VSYASM command line includes multiple source files, any output, list and map paths given on the command line are resolved to their directory components alone and each source code file is then assembled using these directories for the relevant outputs. Before assembly starts, any non-existent directories needed for VSYASM outputs are recursively created. The assembly process itself stops if any file being assembled generates errors.
command line switch can be used to send error reports to a file, in which case this file
will also include the command line used to invoke VSYASM. This provides a way to check
that VSYASM is being called correctly from the controlling Visual Studio build
Firstly, the VSYASM executable file (
be added to the Visual Studio directory holding the C tools. This is typically at:
C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin
Secondly, the three files--
added into the project directory of the project in which VSYASM is being used (an
alternative will be explained later).
Thirdly, to add Yasm support to a project after the project has been opened in the
IDE, right click on the project in the solution explorer and select “Build Customisations…”. If vsyasm is
offered as an option in the resulting list you can then select it; if not, use the
“Find Existing…” button and
the resulting file dialogue to navigate to the
vsyasm.targets that you put in the project directory, select it to add
it to the list and then select it from the list.
Once you have done this, right clicking on the project in the solution explorer and selecting “Properties” will bring up a dialogue with a new item “Yasm Assembler” that will allow you to configure Yasm for building any assembler files added to the project.
