According to the odin help command
$ odin help test
...
-out:<filepath>
Set the file name of the outputted executable
Example: -out:foo.exe
building and running tests the executable output filepath shall be
specified. However, the -out parameter is disabled, resulting in error message:
Unknown flag for 'odin test': 'out'
'out' is supported with the following commands:
run, build
Omitting the -out parameter results in default filepath '01.bin' (on Linux).
However, it is desirable for user specifying the output filepath, e.g. by
using this Makefile snippet:
TARGET=main
FLAGS=-warnings-as-errors -verbose-errors
all: run
run:
@odin run . $(FLAGS) -out:$(TARGET)
test:
@odin test . $(FLAGS) -out:$(TARGET)
clean:
@rm -f $(TARGET)
In addition a typo is fixed.
- Introduce new `Path` type and an array of build paths on the build context.
- Resolve input and output paths/files early (before parsing).
- Error early if inputs are missing or outputs are directories.
- Plumb new file path generation into linker stage instead of its adhoc method.
TODO:
- Remove more adhoc file path generation in parser and linker stage.
- Make intermediate object file generation use new path system.
- Round out and robustify Path helper functions.
A package has canonically always been a directory, but odin allowing you to build a single-file package confused newcomers who didn't understand why they could then not access variables and procedures from another file in the same directory.
This change disallows building single-file packages by default, requiring the `-file` flag to acknowledge you understand the nuance.
`-help` for these commands also clarifies the difference.
```
W:\Odin>odin build -help
odin is a tool for managing Odin source code
Usage:
odin build [arguments]
build Compile directory of .odin files as an executable.
One must contain the program's entry point, all must be in the same package.
Use `-file` to build a single file instead.
Examples:
odin build . # Build package in current directory
odin build <dir> # Build package in <dir>
odin build filename.odin -file # Build single-file package, must contain entry point.
Flags
-file
Tells `odin build` to treat the given file as a self-contained package.
This means that `<dir>/a.odin` won't have access to `<dir>/b.odin`'s contents.
```
```
W:\Odin>odin run examples\demo\demo.odin
ERROR: `odin run` takes a package as its first argument.
Did you mean `odin run examples\demo\demo.odin -file`?
The `-file` flag tells it to treat a file as a self-contained package.
```
OpenBSD uses PIE code by default to allow the system to load the binary at a random location.
don't pass -no-pie to preserve this behaviour, and build objects with -fPIC (LLVMRelocPIC).
