Question

I'm trying to build Moses, but when I run make I get the following output:

/bin/sh: ./check-dependencies.pl: not found
make: *** [release] Error 127

The error message says ./check-dependencies.pl is "not found", but I see the file present in the scripts folder. So why does this error occur?

./check-dependencies.pl is a relative path - maybe make is in another directory when trying to access it? It says it's leaving the scripts dir just before, in case the script is located there. — , Oct 28 '12 at 12:11
Your question has been downvoted and closed because you didn't provide much information, in particular you didn't say what program you're trying to compile or on what system. I voted to close too, though on second thoughts I think I shouldn't have (and I voted to reopen), because I suspect that I've guessed what's going wrong. Really, you should provide more information. (Copy-pasting the whole transcript from the make session was good though.) — Gilles 'SO- stop being evil', Oct 29 '12 at 00:41

The most likely reason for this error is that check-dependencies.pl is not in the directory where the makefile looks for it. However, if the file check-dependencies.pl does exist in /home/minakshi/Desktop/working-dir/moses/scripts, then there's another possibility: maybe its loader doesn't exist.

For a script, the loader is the interpreter mentioned in the shebang line, i.e. the first line, which must begin with #! followed by the path to the interpreter.
For a binary, the loader is the dynamic linker (statically linked executables don't have a loader) — see Getting "Not found" message when running a 32-bit binary on a 64-bit system.

When the kernel is told to execute a program, it executes the loader program and passes it the executable to load. If the loader is not found, the kernel can only report “not found”, it doesn't have a way to distinguish “directly requested file not found” from “loader not found”. Sometimes the executing shell will make a second check to display a more explicit error message, but sometimes you end up with a strange-looking message that tells you that a script or dynamically-linked executable is not found or not executable, when in fact the file does exist and is executable but the error applies to its loader.

With a .pl extension, check-dependencies.pl is presumably a Perl script. It probably starts with a line like #!/usr/local/bin/perl, which doesn't give the path to the perl interpreter on your system. Edit the script and fix the first line; you'll probably have to replace #!/usr/local/bin/perl by #!/usr/bin/perl or vice versa.

Perl is usually located in /usr/bin on Linux, but in /usr/local/bin on many other unices. There's a way to write the shebang line without knowing the path to the interpreter in advance: #!/usr/bin/env perl. The shebang line requires an absolute path; here the interpreter is env which looks up perl in the $PATH. However this only works if there are no arguments to pass to the interpreter: many systems, including Linux, accept a single argument on the command line, so e.g. #!/usr/bin/perl -T works, and #!/usr/bin/env perl works, but #!/usr/bin/env perl -T fails because it tries to execute a program called perl -T.

/bin/sh: ./check-dependencies.pl: not found — but check-dependencies.pl exists!
