Did you tried to use QT_MISC_DIR (which should contains the "mkspecs" subfolder) and QT_DOC_DIR, which should contain for example (QtCore/qtcore.index)? Or if you like, open an issue on github and we can try to sort this out :) edit: also if you use PKG_CONFIG=true, the QT_DIR will be ignored

Hum, I hadn't, but in retrospect I should have. I've done my share of Qt builds in the past and mkspecs path was often an amusing detail. Didn't solve the problem though.

But I think I found out at least one thing that goes wrong. I'll provide a github issue report later this weekend but here's the short version:

* The generated #cgo directives for CXXFLAGS are different for desktop and minimal files. Minimal is generated with -I$(QT_INCLUDE_DIR)/QtFoo include paths; desktop is generated with -I$(QT_DIR)/<major.minor>/gcc_64/include/QtFoo paths instead. So headers in desktop build are looked up from library directory paths (and with obviously bad path elements too).

* When building, qtsetup goes for desktop target.

More data coming in via github once I get the exact details sorted out.

Mh, usually the minimal_cgo_* files and the cgo_* files should use the same imports.

But the qtsetup won't always re-generate these cgo_* files if the QT_DIR is up to date (there is probably a bug if you use QT_PKG_CONFIG).

So I would use `qtminimal` or `qtdeploy` for debugging this, because the minimal_cgo_* files are always re-generate.

And you may also want to change `InfoLevel` in `internal/utils/logger.go` to `DebugLevel` and then re-build the cmd/tools to get additional infos.

Hope this helps :)
