Though by all accounts it's a great tool. OTOH PCLint++ is an excellent tool and identifies a very great number of dubious if not downright erroneous code statements. The biggest values IMO are that it does cross TU analysis and supports use of comments to suppress diagnostics. I.e. if you have looked at an issue it raises and decide that the code is correct you can sign off on it with a comment and so document the fact that the code has been checked. Quote: Unfortunately, we make do by configuring our compiler (Visual Studio) so that it outputs many warnings that are off by default. Although it doesn't give us the coverage that PCLint would it does help somewhat. Sorry, but that does not get even close to what PCLint++ can achieve. Quote: The only problem is that many (many!) warnings are produced within some of the libraries we use (including the Standard Library) so that it masks a lot of the 'real' warnings. That is far from the only problem. Visual Studio just does not provide anything like the same range of error detection and lacks any simple way to suppress false positives. Quote: Anyone else know of freeware tools? I've been keeping an eye out for ages but no luck... Possibly because the cost of PCLint++ is quickly recovered in a professional environment (actually the real cost is in learning to use it effectively rather than in the licence fee) I guess you have already paid many times the cost of PCLint++ in wasted time looking for the real problems in a plethora of nit-picking diagnostics. Look at the total development cost, not just the cost of licence fees. Save 1 day of programmer time and you have recovered the cost of a PCLint++ licence. -- Francis Glassborow ACCU 64 Southfield Rd Oxford OX4 1PA +44(0)1865 246490 All opinions are mine and do not represent those of any organisation [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

On Linux, you can use the Intel 7.1 compiler for no monetary costs, featuring a high-quality EDG C++ front end. Code that passes icc -ansi has a reasonably high likelihood to be at least valid C++. Time an again just oversights while coding result in non-conforming code that is accepted by the compiler one happens to use. icc also features an option for "remarks" (-w2) which I find less useful.

Quote: The only problem is that many (many!) warnings are produced within some of the libraries we use (including the Standard Library) so that it masks a lot of the 'real' warnings. Write a filter to remove the 'unreal' warnings? I seem to remember that someone wrote a decoder for VC's standard library messages, maybe you can create something similar that supresses the warnings in the library code.

And given how much most students earn, licencing costs can soon become a real issue. (It's a point I often forget myself, given the number of years it's been since I was last a student.) That was the reason that I very carefully qualified the advice as concerned with professional programmers. When it comes to students several other issues arise: 1) There code is often small enough to be properly inspected (were I responsible for students I would require code inspections as part of the student's work, possibly including critiques of anonymous code) 2) I have always found Gimpel Software to be a highly responsive firm and I think any academic institution that approached them would find them very helpful with licences restricted to strict student only use -- not least because this would create future programmers who would expect PC-Lint++ or an equivalent tool to be part of the tool set provided by their employers. Note the FlexeLint provides a portable version suitable for use in non-MSWindows environments. 3) Even hobbyist programmers might find that the increased productivity and the reduction in desk thumping merited purchasing a copy of PC-Lint++. They would find they spent more time writing productive code and less time in frustrating debugging. I wonder if Jim has considered releasing a low cost non-commercial version, perhaps the previous release discounted by the cost of upgrading it to the current release? -- Francis Glassborow ACCU 64 Southfield Rd Oxford OX4 1PA +44(0)1865 246490 All opinions are mine and do not represent those of any organisation [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

The only problem is that many (many!) warnings are produced within some of the libraries we use (including the Standard Library) so that it masks a lot of the 'real' warnings. This is a well-known problem with VC++: If you turn up the warning level high enough to be useful then you are swamped with warnings in the VC++ standard headers. The solution is to turn the warning level up on your code, and turn it down when including VC++ headers, as shown here: // warning level is high here #include <your_header> #include <your_other_header> #if defined(_MSC_VER) #pragma warning (push, 2) // set warning level lower #endif #include <map> #include <list> #include <string> #if defined(_MSC_VER) #pragma warning (pop) // restore previous higher warning level #endif // warning level is high again here This seems to work well enough for me, but is still not a substitute for lint and its cousins. At least it does allow regular compilation with a useful warning level. Randy. Quote: Anyone else know of freeware tools? I've been keeping an eye out for ages but no luck...
