## Files
|
||||
|
||||
Simexec is a single C file (`simexec.c`) that builds to a single executable,
|
||||
which should be named `simexec` and placed in a user-accessible binaries
|
||||
directory. A `Makefile` is provided as courtesy but isn't really necessary.
|
||||
- `src/simexec`
|
||||
- Can be moved to a system sources directory if it's desirable to keep
|
||||
system sources on hand. Doesn't reference anything else in the
|
||||
repository.
|
||||
|
||||
The `src/simexec` directory can be moved to a system sources directory if you
|
||||
wish to keep the source on hand; it doesn't reference anything else in the
|
||||
repository.
|
||||
- `simexec.1`
|
||||
- Included manual page for `simexec`. Can be placed in the appropriate
|
||||
manual pages directory. If it displays weirdly and your fix is
|
||||
portable, mail me and I'll probably bring it upstream.
|
||||
|
||||
- `simexec.c`
|
||||
- A single C file that builds to a single executable, which should be
|
||||
named `simexec`.
|
||||
|
||||
The included manual page, `simexec.1` can be placed in the appropriate manual
|
||||
pages directory. If it displays weirdly feel free to e-mail me and I'll attempt
|
||||
to fix it.
|
||||
- `simexec`
|
||||
- Program binary. Should be placed in a user-accessible binaries
|
||||
directory.
|
||||
|
||||
## Dependencies
|
||||
|
||||
- `<sysexits.h>`
|
||||
- Ignored if `EX_USAGE` is already defined.
|
||||
|
||||
- C standard library
|
||||
|
||||
## Compilation
|
||||
|
||||
On systems that provide `<sysexits.h>`, the following is all that's needed:
|
||||
|
||||
```
|
||||
cc -o simexec simexec.c
|
||||
```
|
||||
|
||||
If you're not sure whether your system provides `<sysexits.h>`, try it and see.
|
||||
If it doesn't work, compile `simexec.c` with the following:
|
||||
Or without `<sysexits.h>`:
|
||||
|
||||
```
|
||||
cc -DEX_USAGE=1 -o simexec simexec.c
|
||||
```
|
||||
|
||||
Other than `<sysexits.h>` simexec(1) only relies on headers found in the C
|
||||
standard library. Outside of POSIX environments `simexec.c` probably won't work
|
||||
but it wouldn't be of much use anyway.
