Detangle the target and host DLL and library directories by
making `get-lib-search-dirs` and `get-dll-dir` report the
host system's directories, and add `get-cross-lib-search-dirs`
and `get-cross-dll-dir`.
A new `-C`/`--cross` flag causes `racket` to save a host config and
collection directory and make them available via `(find-system-path
'host-{config,collects}-dir)`, while plus `(system-type 'cross)`
reports whether `-C` mode is in effect. Besides making the host paths
available, this change allows a same-platform build to run in
corss-platform mode.
The immediate problem to solve was the creation of Windows installers
on Windows, where recent changes to support 'gui-bin-dir configuration
need a clear distinction between the host Racket and the target Racket
being built, even if they're the same platform. (The "GRacket.exe"
executable didn't work, for example.)
The changes in this commit are more than needed for the immediate
problem, but they naturally build on the necessary `-C` flag, and they
support cross-platform package setup where native libraries are needed
during setup.
Although "macOS" is the correct name for Apple's current desktop OS,
we've decided to go with "Mac OS" to cover all of Apple's Unix-like
desktop OS versions. The label "Mac OS" is more readable, clear in
context (i.e., unlikely to be confused with the Mac OSes that
proceeded Mac OS X), and as likely to match Apple's future OS names
as anything.
On Unix and OS X, the check to avoid replacing an existing
file or directory is made by Racket, rather than the OS,
so don't claim a system error if the operation fails for
that reason.
Also, update the docs to clarify that the check is not
atomic with the move.
Closes issue #1158
The expression in a `define-runtime-path` form is used in
both a run-time context and a compile-time context. The
latter is used for `raco exe`. In a cross-build context,
you might need to load OpenSSL support for Linux (say)
at build time while generating executables that refer to
Windows (say) OpenSSL support. In that case, `#:runtime?-id`
lets you choose between `(cross-system-type)` and
`(system-type)`.
Merge to v6.4
Also, add `#:skip-filtered-directory?` to `find-files`.
Less significantly, adjust `pathlist-closure` to be consistent in the
way that it includes a separator at the end of a directory path.
Port `examples`, `interactions`, etc., to use the new `examples`
form of `scribble/examples`. The main intended effect is to ensure
that errors are produced by examples only as specifically
indicated.
If a file or directory delete fails, try adjusting the file or directory
permissions to allow writes, then try deleting again. This process should
provide a more Unix-like experience and make programs behave more
consistently.
A new `current-force-delete-permissions` parameter provides access to
the raw native behavior.
