cabal install does not accept relative dirs in --store-dir (but cabal build does)

[andreasabel]

Installation aborts in the middle when a relative path is passed to --store-dir:

$ cabal --store-dir=. install hello
...
In order, the following will be built (use -v for more details):
 - hello-1.0.0.2 (exe:hello) (requires build)
...
Configuring hello-1.0.0.2...
Error: cabal: expected an absolute directory name for --prefix:
./ghc-9.2.1/hll-1.0.0.2-1e2f3837

Error: cabal: Failed to build hello-1.0.0.2. The failure occurred during the
configure step.

$ tree
.
└── ghc-9.2.1
    └── package.db
        ├── package.cache
        └── package.cache.lock

In contrast.

$ cabal --store-dir=$PWD install hello

succeeds.

Would a simple fix be to turn the --store-dir into an absolute path just after parsing this command line argument?

This issue came up before, see #7130 (comment); in #7130 (comment) @phadej invites PRs. A systematic fix has been started in #6667 but is unfinished.

UPDATE: looks like I duplicated #7760.

Dont worry, closing mine. there we also linked as related #6977 and #4097.
I reproduced the error in windows with cabal-3.6.2.0 but any cabal version would do afaiu

Well i liked the title of mine one but whatever: cabal install does not accept relative dirs in --store-dir (but cabal build does)
