wipes out ENV variables

[egbutter]

Hi Jonathan:

Thanks for putting together this great executable. FYI, the installer wiped out my ENV variables (latest "stable" mingw installer on Windows 7). I am not comfortable enough with this code to figure out why myself right now ... just thought I should let you know.

Cheers, and thanks again!

all ENV variables or just the ocaml ones?

[egbutter]

The Ocaml and TCL variables replaced all my _other ENV variables; so the final state of the system-wide ENV variables was (C:\Tcl\bin;C:\OCaml\bin;).

Are you talking about the PATH environment variable? An environment variable has a name and a value. Please tell me what is the name of the environment variable that was damaged, what is its value now, what used to be its value.

Thanks,

Correct, the PATH env variable. Before: C:\prover9\bin;C:\pscp;C:\puTTY;C:\Python27;C:\Python27\Scripts;C:\R\R-2.14.0\bin;C:\Vim\vim73;C:\boost\boost_1_47_0; ... and many more. After: C:\Tcl\bin;C:\OCaml\bin; Sorry I was not too clear. Cheers,

Eric

Looks like you just hit the 1024 character string length limitation in the installer I'm using...

It would be helpful if you could create a new installer. With this problem, I hesitate to recommend OCaml to Windows users.

[egbutter]

I hesitate to recommend Windows =) we make have with what we are given!

[protz]

I'm happy to announce that the new installer at http://yquem.inria.fr/~protzenk/caml-installer/ocaml-4.01.0+dev0-i686-mingw64.exe is able to cope with larger PATHs and won't blast the PATH in case it really is super-long.

Please can you put a warning in front of the link to the old version of the installer, which still has this problem.

I just ran it and I now have several hours work ahead of me fixing every other command-line tool on my system. I know it’s “unsupported” but I wasn’t expecting it to do serious damage.

[protz]

Alright, I guess it's fair I put up a bigger warning. The page has been updated.

Thanks! I hate to think of someone else suffering the same fate! :)
