Can't build workspacce #1

Closed therealprof closed 5 years ago

therealprof commented 5 years ago

Trying a cargo build in the workspace path generates:

error: failed to run custom build command for `stm32-usbd v0.1.0 (/Users/egger/OSS/stm32-usbd-examples/stm32-usbd)`

I'm not sure if it's possible to build something useful with this command in workspace root. What did you expect to get as a result?

therealprof commented 5 years ago

My expectation would be that all the workspace members are built individually. This is how example crates usually work, like: https://github.com/actix/examples.git

I hope this commit makes things a bit better: https://github.com/Disasm/stm32-usbd-examples/commit/818a37e20d407bb952166087465d59f06455c244

$ cargo build
error: manifest path `/tmp/stm32-usbd-examples` contains no package: The manifest is virtual, and the workspace has no members
Disasm commented 5 years ago

Unfortunately, some of the workspace members are not examples and also examples need to be compiled with different architecture targets. However, if you have any ideas -- please tell me.

therealprof commented 5 years ago

Hm. Unfortunately the instructions also don't work... at least this the STM32F042 example doesn't compile out of the box:

$ pwd
/Users/egger/OSS/stm32-usbd-examples/example-stm32f042k6
$ cargo build
error: no packages to compile

Oh, that last fix broke everything.
