Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: 6.4 Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Hardcoded path to perl.exe Initial Comment: I apologize in advance for not selecting a proper category but as I am an extreme neophyte - I didn't know what to select. I use GHC primarily to build Pugs (http://pugscode.org) I got frustrated that on Win32, the current working directory supercedes the %PATH variable and the perl.exe in the GHC root directory was getting used instead of my freshly installed 5.8.7 I deleted the file and corresponding perl56.dll and everything appeared to be working fine and yet Pugs would fail to build spitting out a cryptic 0x01 error (not exactly sure what the code was but it wasn't helpful). Since I had deleted the files instead of renaming them (hindsight always being 20/20) and not wanting to install GHC all over again just to see if for some strange reason that was the problem - I copied over the perl.exe and perl58.dll and what do you know - it worked. My bug report then is this - if there is some valid reason to hardcode a path to the GHC root directory for perl instead of looking in %PATH as a backup plan - then please make any error message more descriptive. Note: Not being very familiar with GHC, it might be that the error message was very informative and that it is the Pugs build process fault for not carrying it over. If that is the case then please disregard and please forgive. Cheers, Joshua Gatcomb a.k.a.

As a non-registered user, I suspect my reply will be posted under the root thread instead of simonpj It is a problem for a handful of reasons. 1. When I in the GHC root directory, that version takes precedence over any system installed perl. In addition to being a different version, it does not have access to all the modules installed in the system perl's @INC 2. The error message that the executable is missing in no way tells me that is what the problem is. As I indicated previously, it may be that the Pugs build process just wasn't passing on the information correctly - but I don't suspect this is the case. 3. I am not saying that GHC should not include its own copy of the perl executable for many of the same reasons you indicated. I am saying that it would be more user friendly if it looked in %PATH if it wasn't found in the hard coded path as backup. Alternatively, renaming it. As a command line biggot, this is primarily only a problem on Win32 as the current directory takes precedence over the PATH environment variable. Making this more user friendly can, in my neophyte opinion, be done without a negative impact to GHC's goals. Cheers, Joshua Gatcomb a.k.a.

We consider it a feature, not a bug, that GHC invokes its own private copy of perl when GHC runs its own private perl scripts (actually, I think the only perl script is the Evil Mangler). That way we aren't exposed to version skew in perl, nor do we require users to even have perl installed. Why does it cause a problem for you? Perhaps GHC's perl doesn't run on your box. But I wonder why not.... The only script it's being asked to run is the one that comes with GHC itself.
