Hi Nikolai, Benjamin

What is a "normal toolchain", Boot2Qt, Yocto, Qbs or own QtC sauce?


Hi!

I've just meant a tool chain targeting the desktop. The one that you get 
as auto-detected "Desktop Kit" if you install Qt + Qt Creator.

When people say "toolchain" without further clarification, they usually mean 
compiler
toolchain which consists of preprocessor, compiler, assembler, and linker

Hi Nikolai, Benjamin

What is a "normal toolchain", Boot2Qt, Yocto, Qbs or own QtC sauce?

I am trying to use the clang.exe that is installed with Qt Creator by using the
Static Analyzer function of Qt Creator.

I have no direct control of the command line that is used to invoke clang.
All I can do is configure Qt Creator to use my gcc toolchain and change
my project file. But clang seems to handle it properly, if you exclude
the header
issue.

Are you trying to substitute a gcc cross-compiler with a native clang compiler?

Have you tried to use gcc's -isysroot that point to the tooolchain
installation prefix?

There's as well a few clang-static-analyser and/or scan-build options
such as --analyzer-target --triplet, ...
I don't have the recipe at hand, but AFAIR you need to tell clang that
this is cross compiled.

Hi,

I have an arm-none-eabi gcc toolchain. I have successfully configured Qt Creator
to use it in a Kit and was able to use it to build QBS projects.

However, when I try to run the static analyzer, clang does not find
the standard headers:

 main.cpp:9:10: fatal error: 'cstring' file not found

A solution is to add the include paths of the standard headers in the
QBS project:

 cpp.includePaths: [
 ".../toolchain/arm/arm-gnu-toolchain/arm-none-eabi/include/c++/6.3.1",
 ".../toolchain/arm/arm-gnu-toolchain/arm-none-eabi/include",
 ]

But this is a bit ugly.

Is there some configuration I missed (I guess not since the build

There is not much configuration for the clang static analyzer.

Please create a bug report with:
 * used versions of Qt Creator and configured clang version for the 
analyzer
 * whether this already happens with a "normal" toolchain. If not, 
please provide some information how to set up your used toolchain.

[Qt-creator] Clang Static Analyzer does not find STL headers

[Benjamin TERRIER]

Hi,

I have an arm-none-eabi gcc toolchain. I have successfully configured Qt Creator
to use it in a Kit and was able to use it to build QBS projects.

However, when I try to run the static analyzer, clang does not find
the standard headers:

main.cpp:9:10: fatal error: 'cstring' file not found

A solution is to add the include paths of the standard headers in the
QBS project:

cpp.includePaths: [
".../toolchain/arm/arm-gnu-toolchain/arm-none-eabi/include/c++/6.3.1",
".../toolchain/arm/arm-gnu-toolchain/arm-none-eabi/include",
]

But this is a bit ugly.

Is there some configuration I missed (I guess not since the build
works), or is it a known bug ?

Thanks,

Best regards,

Benjamin
