I did this: pkg install lang/clang-devel export PATH=$PATH:/usr/local/llvm-devel/bin scan-build cc a.c scan-build: Using '/usr/local/llvm-devel/bin/clang' for static analysis a.c:10:10: warning: Use of memory after it is freed a[5] ='b'; ~~~~ ^ 1 warning generated. scan-build: 1 bug found. scan-build: Run 'scan-view /tmp/scan-build-2015-02-16-211517-60875-1' to examine bug reports. scan-view /tmp/scan-build-2015-02-16-211517-60875-1 Traceback (most recent call last): File "/usr/local/llvm-devel/bin/scan-view", line 131, in main() File "/usr/local/llvm-devel/bin/scan-view", line 128, in main run(port, options, root) File "/usr/local/llvm-devel/bin/scan-view", line 57, in run import ScanView ImportError: No module named ScanView It looks like some stuff for scan-view is missing from the port. Do you have any ideas offhand what is missing? It's not so important, because the results of scan-build can be opened up in any web browser, independently of scan-view. Would it be possible to include scan-build somwehere under /usr/src/contrib/llvm in the FreeBSD source tree? It seems like it is handy to have. However, if it is better to only have it in the port and not in src, I understand. -- Craig -- Craig
