Eiffel 25.12: no macosx-arm64 target and missing class reference docs

["João M. Rocha"]

The Eiffel FTP server provides Eiffel 25.12 for targets such as linux-arm64 and macosx-armv6 but there is no macosx-arm64 for Apple Silicon. I also noticed that this version doesn't include the Porter Package.

Another thing I caught was that the class reference documentation doesn't seem to be available. For example, the link https://www.eiffel.org/files/doc/static/25.12/libraries/base/index.html (from https://www.eiffel.org/doc/solutions/EiffelBase_Class_Reference) appears to be missing.

Is there a specific reason for this that I might be unaware of?

Thanks,
João

Thanks for the report.

We fixed the documentation.

For the macosx, it seems to be a mistake, try the macosx-armv6 on your Apple silicon.

I confirm that the binaries for "macosx-armv6" are targeting arm64 but it seems there are some issues with `ec` and `ecb`.

ec:

Running `ec -version` aborts with the following error:

```

dyld[95765]: Library not loaded: /opt/local/lib/libiconv.2.dylib

  Referenced from: <5775A28B-2832-3BAE-8806-DCA22238A600> (...)/Eiffel_25.12/studio/spec/macosx-armv6/bin/ec

  Reason: tried: '/opt/local/lib/libiconv.2.dylib' (no such file), '/System/Volumes/Preboot/Cryptexes/OS/opt/local/lib/libiconv.2.dylib' (no such file), '/opt/local/lib/libiconv.2.dylib' (no such file)

```

The folder `/opt/local` doesn't exist and ec should be linking libiconv.2.dylib at `/usr/lib/libiconv.2.dylib`.

ecb:

Running `ecb -version` works fine and ecb links correctly:

```

/usr/lib/libiconv.2.dylib (compatibility version 7.0.0, current version 7.0.0)

/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1345.100.2)

```

but compiling a hello world

```

ecb -batch hello.e

```

aborts with the message

```

ld: warning: /Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libSystem.tbd, ignoring unexpected dylib text stub file

ld: archive member invalid control bits in '/Users/joao/Eiffel User Files/25.12/precomp-ecb/spec/macosx-armv6/EIFGENs/base-scoop-safe/W_code/preobj.o'

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make: *** [hello] Error 1

```

However, compiling it again produces a working binary. 

I noticed that `ecb` creates an unexpected symlink `User`. It points to `$HOME/Eiffel` but that directory doesn't exist. 

Subsequent calls to `ecb` reveal it's creating the same symbolic link everytime without removing the existing one, making `ln` output a warning

```

ln: failed to create symbolic link 'User': File exists

```

I also tried this with the previous version 25.02 and it's the same thing.

Jocelyn, while I'm at it, I recently opened an issue and submitted a patch to the eiffel-docker/eiffel repo but I'm not sure if it was seen. Is the repo still maintained?
