Subject: [PATCH 31/31] HACK: qmake: Workaround installation race of
|
qtdeclarative qmltypes
|
|
When doing in-place building, the generated qtdeclarative's
|
plugins.qmltypes might be installed from qtbase's qml2build and
|
qtdeclarative's install_qmltypes stages.
|
|
That would cause a parallel installation race which might lead to:
|
Error copying xxx/plugins.qmltypes to xxx/plugins.qmltypes: Destination file exists
|
|
Let's workaround it by simply adding a few retries.
