Unable to create directory in /usr/share

Asked 2020-Dec-02 at 13:05

I have heard its a conventional practice to store program dependent files in /usr/share/application-folder in linux. So I'm trying to do it in my c program in a function called load_interface_files() for example. I am not sure if this is a good practice or not, I've heard about creating configuration files for this kind of issues.

Anyways, here's the the code I wrote to make a directory in /usr/share.

use ls -ld /usr/share to see what the permissions on the directory are (without -d, you get the contents and their permissions).

The program is ill-formed because the move constructor is used, but not defined which violates the One Definition Rule. The scanner diagnostic may be false positive caused by this bug in the program.

The copy constructor is not used, but it is broken because it potentially indirects through a null pointer.

Clang scan-build identifying CXX compiler as GNU 9.1.0, not clang

Asked 2019-Oct-24 at 11:56

I was trying to use scan-build with cmake. Following scan-build make after scan-build cmake. But when using scan-build, it is identifying CXX compiler as GNU 9.1.0. But if we don't use scan-build it properly identify CXX as clang. Because of CXX compiler identified as GNU 9.1.0, checks for some diagnostic flags in clang (eg, Wunreachable_code_break, Werror_range_loop_analysis) are getting failed.

I think in this case, the static analyzer is wrong. I tried it with clang 9.0 and got a different set of results, but they also look wrong. If you follow the list of steps, you'll see there's something missing:

Using Clang Static Analyzer directly on bitcode files

I wanted to know if clang analyzer can be made to work directly on bitcode (*.bc) files?

For example, when I used the following C code with:

clang static analyzer works on clang AST. It cannot use bitcode as input – it's low-level for the analyzer.

ANSWER

I would derive separate classes from B and C (possibly even using a template class).

These classes would contain a non-reference member which becomes the thing that a and b refer to.

I'd then implement the necessary copy constructors / assignment operators in these derived classes to prevent dangling references.

(Then I'd have a robust conversation with the author of B and C).

ANSWER

Answered 2017-Mar-10 at 07:22

Maybe you are not doing something right. For example, the third example Visual Studio 2015 even refused to compile with error:

error C2124: divide or mod by zero.

I don't think Clang is not capable of detect something like that. However, this is not important.

I tried to check this code using PVS-Studio and it detected all three errors:

V609 Divide by zero. Denominator 'h' == 0. MFCApplication2 mainfrm.cpp 17
V614 Uninitialized variable 'h' used. MFCApplication2 mainfrm.cpp 23
V609 Divide by zero. Denominator '0' == 0. MFCApplication2 mainfrm.cpp 28

Therefore, I recommend you still experiment. At least the third case should be exactly found by Clang. A practical recommendation is to use more powerful tools, such as PVS-Studio, for analysis. He, by the way, finds errors in Clang and GCC.

QUESTION

Android NDK - static analysis for native c++ code

Asked 2017-Jun-26 at 04:52

Is there a static analysis tool integrated into the Android NDK for native code? From my understanding, it looks like the NDK recently transitioned to CLang which I think has a built-in static analyzer (https://clang-analyzer.llvm.org/scan-build.html), but I can't seem to find out how to use it. I am guessing I just need to update my CMake file somehow?

I searched through all the gradle tasks using "./gradlew tasks --all" and I saw the "externalNativeBuild" task but that just builds the native source code.

Ideally, I would like to just run a single command/task and an output file is generated with all the static analysis issues for my native code -- similar to Java's "lint" task where an HTML file is created.

Thanks!

I do not think you have an integrated tool for that in Android Studio. However, you can also try CppCheck. It is not perfect, but it is not bad at all and saved me in several occasions. You can use it for single files or build a project once and load it each time. It is also free.
