[Qt-creator] Qt Creator Clazy Support

[Jeff Tranter]

I'm trying to get the new Clazy support in Qt Creator working.

I have Qt Creator 4.6.0 rc1 compiled from source against Qt 5.10.1 on
Ubuntu Linux.

In Tools / Options, under Analyzer, it shows:

Clang executable: clang-5.0
Version: 5.0.0, supported.

Under C++ / Code Model, is says:

"The Clang Code Model is disabled because the corresponding plugin is
not loaded."

Under Help / About Plugins... it shows ClangStaticAnalyzer loaded,
version 4.5.83.

I also have clazy built from git and installed and it runs on its own.

I am able to run the Clang static analyzer from Qt Creator but I can't
seem to run or configure clazy.

Any ideas?

You need to enable the ClangCodeModel plugin, not ClangStaticAnalyzer.

Hi Jeff,

I am no expert on the code model, please correct me if I am wrong!

Even with clang code model support: This will probably not work with the
system-provided clang:-(

The code model uses libclang, which can not load dynamic plugins. So you
need to have the flags plug-in statically linked into clang for it to be
available.

This makes building clang annoying: You need to build clang, then a static
version of flags, and then clang again, linking to the static flags:-(

The simplest thing you can do is probably to grab a pre-build clang from
download.qt.io.

Best Regards,
Tobias

Hi!

In fact we currently build clang only once with all plugins since it has become possible to put clazy in clang/tools/extra folder.

All steps are in our clang build script (https://github.com/qtproject/qtsdk/blob/master/packaging-tools/build_clang.py)


It's still pretty complicated so basically "grab a pre-build clang from download.qt.io<http://download.qt.io/>" :)


Kind regards,

Ivan

Sidetracking:
I wonder if you could easily put clang-format there as well.
So the beautifier plugin could use that one (as default) to avoid the extra
download/install.

Hello,

The documentation for the Clang code model is maybe a little bit hidden away, but you can find it here:
