Hi Prashanth,
I'm exploring writing a simple uart driver for linux in order to get terminal_mux working on linux. When I disable the linux spec check in terminal_mux.run, the build always picks up:
Program drivers/uart/spec/x86/uart_drv
even though I created a drivers/uart/spec/linux/
and changed drivers/uart/spec/linux/target.mk to read
REQUIRES = linux
and the etc/specs.conf in the build directory to read:
SPECS += linux x86_64
I'd like to know how I can get the build to say
Program drivers/uart/spec/linux/uart_drv
I suspect that the build system actually picks up and builds both targets because each of them meets the SPECS as defined for the build directory. The problem is that the targets are named the same. So the symlink in '<build-dir>/bin' is overwriten by the target last visited. To check this assumption, you may have a look at the content of the build locations for the two drivers in question:
<build-dir>/drivers/uart/spec/linux <build-dir>/drivers/uart/spec/x86
I presume that each of those locations contains the respective executable.
The best way to solve the ambiguity would be to give your driver a distinct name, e.g., by adding the following line in your 'spec/linux/target.mk' file:
TARGET = linux_uart_drv
Now, both drivers should appear in the bin/ directory side by side.
