Hi all,
I am involved in a software project targeting a handful of ARM Cortex-M
microcontrollers. We develop the software using the Keil uVision v5 IDE [1]. We
are considering whether CMake could help us with some of the limitations we
encounter using uVision alone.
Does anyone have experience or insight in to creating a CMake generator for an
embedded systems IDE like uVision?
Read on for some technical details.
A uVision project's structure appears _roughly_ similar to a Microsoft Visual
Studio 12 project. uVision has a Multi-Project Workspace (.uvmpw) rather than a
VS solution (.sln), and a uVision Project (.uvprojx) instead of a VS project
(.vcxproj).
One notable difference in the XML schemas: in uVision, the source file elements
are a child of the target elements (a uVision "target" is comparable to a VS
"configuration"), in contrast to VS's approach where a configuration-specific
option is a child of the source file element and has a "Condition" attribute.
As with the Visual Studio generators, a generator for uVision projects would
ideally be a multi-configuration generator.
I expect there are many concepts in CMake that wouldn't map to a uVision option,
and vice-versa. For example the "Packs" system used by uVision might not mesh
well with what CMake understands as a library. For my limited requirements -- a
single project workspace, where the project consists of exactly one executable
and no libraries other than some third-party libraries passed to linker -- I
expect we could make do with a skeleton/template .uvprojx and the CMake
generator would fill in the gaps for the source files.
Some of the benefits I would imagine we would get from such a generator:
- more human-friendly and diff-friendly project files (CMakeLists.txt instead
of .uvprojx)
- avoiding a combinatorial explosion of configurations by using the CMake
language and its cache variables.
