Bug ID: 15615
Summary: Crosscompiling TableGen with CMake does not work with
a non-default generator
Product: tools
Version: trunk
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P
Component: TableGen
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Classification: Unclassified
When running CMake for the native TableGen in a cross-compiled environment, a
default generator is used. If it does not match the generator used by the cross
cmake, build will fail (confirmed with Ninja generator).
A fix is trivial:
diff --git a/cmake/modules/TableGen.cmake b/cmake/modules/TableGen.cmake
index e3bdd9c..944394f 100644
--- a/cmake/modules/TableGen.cmake
