On our way to the ACCU Conference
|Sunday, March 30, 2008
It's that time of year again. Tomorrow lunchtime Beth and I will be leaving the palm trees behind and driving up to Oxford for the ACCU Conference (we're going up a day early to do the "Fun with Erlang" pre-conference workshop).
This year we're sponsoring the conference for the first time (as we did with the European Software Conference last year, so if you would like a "show and tell" on any of our software please do come up and ask. Although we won't have a stand running throughout the whole week (the sessions are far too interesting for that!) we will have a stand at the sponsors reception on Wednesday morning.
If you miss us then, we will of course be happy to do impromptu demos in the bar on request.
I haven't gone through the conference schedule in detail yet, but if last year's event is anything to go by it will be informative, fun, and very, very tiring (and that's just the evening celebrations!).
We hope to see you there.

.vsprops files and additional include folders
|Tuesday, March 04, 2008
One of the most useful features of PC-Lint is its ability to process Visual C++ project files and generate
.lnt files containing the corresponding project settings for a given configuration. This of course frees the user from the truly horrible (believe me, I've had to do it on occasion!) task of manually keeping the
.lnt files and all the defines and include folder specifications they contain synchronised with the project files.
In most cases this works fine, although there can be subtleties in the project file formats which PC-Lint may be unaware of - for example for loop compliance (
+/-ffb) options. To process these, Visual Lint includes a Visual C++ project file parser and project.lnt generator which it will by default use in preference to the equivalent PC-Lint capability. The capabilities of the project file parser and project.lnt generator are regularly updated to cope with special cases our customers have advised us of while using the product.
One such case we encountered recently (and is now handled correctly by Visual Lint 18.104.22.168) concerns .vsprops files. These are normally encountered when custom property pages are added to a Visual C++ project:, and as such we did not originally consider them in our project.lnt file writer:
<?xml version="1.0" encoding="Windows-1252"?>As it turns out we were wrong in that assumption, since
<Platform Name="Win32" />
.vsprops files can also contain additional include folder specifications - as the following example shows rather well:
<?xml version="1.0" encoding="Windows-1252"?>
InheritedPropertySheets attribute within his file shows another unexpected characteristic - these files can be nested. In this particular case, the file calls up another .vsprops file (
macros.vsprops) prior to defining the additional includes. This defines the
$(MyIncludeDir) project specific environment variable seen in the
When Visual Lint reads a project configuration which includes an
<?xml version="1.0" encoding="Windows-1252"?>
InheritedPropertySheets attribute, it will now recursively read the referenced
.vsprops file (and any it references) and attempt to resolve any resultant include paths.
If all of the paths are referenced correctly, the fully expanded include folder specification should be visible in the
project.lnt file generated by Visual Lint:
One important caveat to note is that this process can only work if Visual Lint is configured to write the
// Generated by Visual Lint 22.214.171.124 from file:
-D_UNICODE;UNICODE // CharacterSet = "1"
-DWIN32;_DEBUG;_CONSOLE // PreprocessorDefinitions = "WIN32;_DEBUG;_CONSOLE"
-D_NATIVE_WCHAR_T_DEFINED // TreatWChar_tAsBuiltInType = "TRUE"
-D_MT;_DEBUG;_DLL // RuntimeLibrary = "3"
VsPropsExample.cpp // RelativePath = "VsPropsExample.cpp"
stdafx.cpp // RelativePath = "stdafx.cpp"
project.lnt files itself (the default). If PC-Lint is being used to process the .vcproj files it will (as far as I am aware) ignore the
.vsprops files and thus any additional includes defined within them will not be reflected in the analysis configuration.
To check whether this option is correctly set, open the "Visual C++" page within Visual Lint Options:
