The error "cannot create directory '/path/to/directory': Read-only file system" makes no sense - the file system is not read-only, and "directory" is not the name of this directory (it should be "directory with spaces"). I can confirm that instead using directory-with-hyphens makes this succeed.
Could you try with the latest version of opam (2.1.5)? And if it doesn't work could you try with the latest alpha for opam 2.2?
To install opam 2.1.5:
bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh)"
to install opam 2.2.0~alpha2:
bash -c "sh <(curl -fsSL https://raw.githubusercontent.com/ocaml/opam/master/shell/install.sh) --dev"
opam 2.0.5 is fairly old (4 years old) and based on a 5 years old branch so bugs that have been fixed since is to be expected.
note from & for opam dev team: it is at least working in opam 2.2~alpha, as a reftest succeed switch creation and installing a package in a path with spaces.
On Linux, even with opam 2.2~alpha2, I get an error

Sorry I’m not sure why I didn’t remember this on my first read of the issue, but this is happening because OCaml doesn’t support spaces in the prefix.
This was fixed in 5.1.0 and was backported in the 4.14 and 5.0 branches so it should be fixed once 4.14.2 and 5.0.1 are released. See https://github.com/ocaml/ocaml/pull/11590 cc @octachron
Closing since it is not an issue in opam, sorry I hadn’t realized sooner.
I'm facing the same kind of error with opam 2.2.0~alpha2 and ocaml 5.1.0. The message is different. So I wonder if the problem is opam or ocaml?

@Khady if you don’t clean up the switch and look into what’s in /tmp/my folder with spaces/_opam/bin/, what do you have? (if possible using ls -l to see if the executables are correctly flagged)
for the record

I couldn't find where the full logs are, but # command ~/.opam/opam-init/hooks/sandbox.sh build ocaml /tmp/my folder with spaces/_opam/share/ocaml-config/gen_ocaml_config.ml 5.1.0 ocaml is a bit fishy, as if it was missing some quoting
Mmmh, this seems to be a fondamental issue with the way executables are read in Unix systems...
The directory shows ocaml well installed and everything but trying to start the interpreter leads to the following error:
./_opam/bin/ocaml
zsh: ./_opam/bin/ocaml: bad interpreter: /private/tmp/my: no such file or directory
The first line of the ocaml executable is the following:
#!/private/tmp/my folder with spaces/_opam/bin/ocamlrun
However according to https://lists.gnu.org/archive/html/bug-bash/2008-05/msg00052.html it is not possible to have a path with spaces in it :/
Right, so I suppose that opam is innocent and this issue should be reported to ocaml/ocaml. Thanks for your help!
I’m hearing in my earpiece that the relocatable compiler work might fix this issue whenever it lends in the compiler. But it’s definitely worth opening a new issue in ocaml/ocaml to track this.
I’ll keep this issue opened until the proper fix lends.
ok, investigating this a little bit more before to open an issue on ocaml/ocaml, I realized the problem could/should be fixed in https://github.com/ocaml/opam-repository/blob/7b4cedddee88c79d6bdb00eccf7b36a7b617b211/packages/ocaml/ocaml.5.1.0/opam#L20, and opam show ocaml points to https://github.com/ocaml/opam-repository, but I wonder if it's better to talk there or here.
It is possible to launch the ocaml binary with ocamlrun instead of relying on the shebang:
sg:/tmp/my folder with spaces$ _opam/bin/ocamlrun _opam/bin/ocaml _opam/.opam-switch/build/ocaml-config.3/gen_ocaml_config.ml 5.1.0 ocaml
sg:/tmp/my folder with spaces$ ls
_opam ocaml.config where
sg:/tmp/my folder with spaces$ cat ocaml.config
opam-version: "2.0"
variables {
native: true
native-tools: true
native-dynlink: true
stubsdir: "/tmp/my folder with spaces/_opam/lib/ocaml/stublibs:/tmp/my folder with spaces/_opam/lib/ocaml"
preinstalled: false
compiler: "5.1.0"
}
sg:/tmp/my folder with spaces$ cat where
/tmp/my folder with spaces/_opam/lib/ocaml
So I wonder if the build instruction of ocaml should be changed from
build: ["ocaml" "%{ocaml-config:share}%/gen_ocaml_config.ml" _:version _:name]
To something like
build: ["ocamlrun" "%{bin}/ocaml" "%{ocaml-config:share}%/gen_ocaml_config.ml" _:version _:name]
It’s indeed possible but the problem is that the ocaml package is not the only place where a bytecode binary is called.
For example on platforms that do not have native backend support, all ocaml programs have this issue. So you would be able to install the compiler but any other packages would still have to be patched and that’s simply too much work. Especially for an issue that is going to be fixed hopefully soon-ish ^^
I can confirm that opam itself works fine with spaces and that ocaml will support spaces as part of Relocatable OCaml:
$ cd /tmp
$ mkdir "dir with spaces"
$ cd "dir with spaces"
$ opam switch create --empty --repos=reloc,default .
$ opam install ocaml-base-compiler
[...]
$ ocamlc -where
/tmp/dir with spaces/_opam/lib/ocaml
$ which ocaml
/tmp/dir with spaces/_opam/bin/ocaml
$ ocaml test.ml
