[llvm-dev] [cfe-dev] scan-build on Windows
+Aaron because i think he uses scan-build on Windows more or less successfully. I won't have time for setting up a Windows machine for myself in the nearest future. Could you tell us exactly what you're doing and what exactly does it print to console, more in the spirit of http://www.catb.org/~esr/faqs/smart-questions.html ? > scan-build: Not supported for windows.

Normally you don't care where is everything installed because you simply provide the path to the analyzer with `--use-analyzer`.

[llvm-dev] [cfe-dev] scan-build on Windows
Hi Artem,
Couple of points to note here :-
There are two things we are trying to do :-
1) Trying to run scan-build on Windows
2) Running scan-build in linux and generating HTML reports in report
directory
*We are just trying to run scan-build with normal makefile which compiles
and analyzes one test case.*
The problem in the first case is that when i run the normal scan-build with
build command like this :-
C:\Users\sid>perl -S scan-build -o out-dir make
scan-build: Not supported for windows. Exiting...
For the second case our aim is to just run scan-build with build command
for one test case file which will be analyzed and reports will be generated
in the reports directory
sid at sid-linux:
/local/mnt/workspace/llvm/tools/clang/tools/scan-build/bin/scan-build
--use-analyzer=/local/mnt/workspace/llvm/build/bin/clang make
scan-build: Using ' /local/mnt/workspace/llvm/build/bin/clang' for
static
analysis
/local/mnt/workspace/llvm/build/bin/../libexec/ccc-analyzer -o test1 test1.c
test1.c:6:9: clang_sa_warning: Value stored to 'k' during its
initialization is never read [deadcode.DeadStores]
int k = *j;
^ ~~
test1.c:6:13: clang_sa_warning: Dereference of null pointer (loaded from
variable 'j') [core.NullDereference]
int k = *j;
^~
2 warnings generated.
scan-build: Removing directory
'/tmp/scan-build-2019-04-10-115314-8475-1'
because it contains no reports.
scan-build: No bugs found.
It shows bugs in the cmd but doesn't generate HTML reports. What can be the
possible cause of it ? ( Note here the clang is the latest version) Is
there any dependency from scan-build side that it will work with a
particular version of clang ?
Thanks,
Siddharth

[llvm-dev] [cfe-dev] scan-build on Windows
I don't fully understand what's going on in your case, but could you try removing the "CC=" line from the makefile? 'Cause it's the whole point of scan-build that it injects the analyzer through CC, so it can't work if you immediately overwrite it back. I think normally makefiles only enforce their own CC if it's unset otherwise.
