Have you tried other ports? Native linux does not dump. Why would it? Dumping any interpreter sounds like a pretty stupid plan. Your brother might at this very moment be logging a bug against activeperl for that particular behaviour. The only good approach I can think of is to re-define the backticks to explicitely dump.

Easier said than done. First of all, this is NOT about MAX_PATH. MAX_PATH (260 chars) is the number of characters allowed in the Win32 ANSI file API for a complete path, including the terminating null. Cygwin is using the native NT API and, occasionally, the Win32 UNICODE file API, which allows paths of up to 32767 chars. The problem here is about NAME_MAX. NAME_MAX is per POSIX[1] the "maximum number of bytes in a filename (not including the terminating null)." Note the word *bytes*. Not characters, bytes. UTF-8 chars are 1 to 4 bytes in length. Thus, the maximum number of UTF-8 chars in a filename is potentially less than NAME_MAX: A filename of chars only from the basic latin charset (1 byte in UTF-8) may consist of NAME_MAX characters, a filename solely constructed from chars of the latin-1 supplement (2 byte chars) may consist of NAME_MAX / 2 characters, a filename constructed from emoticons (4 byte chars) only of NAME_MAX / 4 chars. Ok, so we all know that Windows is not using a byte representation of filenames, rather the OS uses UTF-16 to store and handle filenames internally. Filename on Windows filesystems may consist of 255 UTF-16 chars[2]. How do you represent this in a byte-oriented POSIX system? What do you set NAME_MAX to? You can't get it right due to the unfortunate multibyte vs. UTF-16 encoding issue. To cover all UTF-8 chars, NAME_MAX would have to be 1020. But then, applications relying on NAME_MAX will be surprised by ENAMETOOLONG errors for perfectly valid POSIX filenames. If you make it 255, applications will be surprised by ENAMETOOLONG errors for perfectly valid Windows filenames. If you make it 255 on the application level but then return filenames longer than 255 multibyte chars to the application, they will crash due to buffer overflow issues. After all, NAME_MAX is a contractual obligation. There was also the backward compatibility issue. Back in the pre-Cygwin 1.7 days, when Cygwin used the ANSI file API, NAME_MAX was already 255. Changing that to a bigger value might have resulted in the aforementioned application crashes due to buffer overflows as well. So we decided to keep NAME_MAX at the same value as it always was, 255. This restricts the actual filename length when using multibyte characters just as on any other POSIX system with the downside that, occasionally, a Windows filename will be too long to handle. Sorry if that is frustrating in your current situation, but this isn't something we can just change at a whim and go ahead. It would break compatibility with all existing Cygwin executables. Corinna [1] http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/limits.h.html [2] However, this does *not* cover NFS or other filesystems using a byte representation for storing filenames. -- Corinna Vinschen Please, send mails regarding Cygwin to Cygwin Maintainer cygwin AT cygwin DOT com Red Hat pgp2au0HOT0is.pgp Description: PGP signature

That's weird. I never saw that happen with the -d/-D option. Especialy because mkpasswd -d/-D doesn't rely on any user name, it just asks the domain controller to list the domain accounts using the NetUserEnum function, and NetUserEnum is not documented to be able to return error 2221 (NERR_UserNotFound) at all. Are you running this under a domain account?

Hardcoding header file locations isn't very clever, esp. if that means
things break even after applying a point update to gcc (4.7.3 to 4.7.x).
Below is a modified version of llvm's 3.1-cygwin-includes.patch that
attempts to address the issue for a certain time. Rather than relying on the
exact version/pathname, it assumes that someone will maintain a symlink as
is customary with shared libraries, e.g. (for current releases)
ln -s 4.8.2 /usr/lib/gcc/i686-pc-cygwin/4.8
Use setup.exe to get the llvm and clang sources and, most importantly,
llvm.cygport. Call cygport llvm.cygport prep inside /usr/src and interrupt
it when it starts patching. Replace the original includes.patch file with
the modified one, call cygport llvm.cygport all (or almostall) and go do
something else.
When this commands finishes, /usr/src/llvm-3.1-3/dist/llvm will contain all
llvm .tar.xz installer packages, which can be installed using
tar -C / -xJf package.tar.xz .
There doesn't appear to be any need to modify the libdirs.patch file.
What also surprises me is that cygwin is so much behind with llvm/clang
versions!

possible missing dependency for python-numpy and proposed fix
Hi, I recently installed a new version of Cygwin on a new Windows 7 machine. I installed a several packages including numpy. The installation worked without any errors. I did this for both 32 and 64 bit versions of Cygwin. After installing numpy I tried importing it in a Python shell. It raised an ImportError exception when trying to import lapack_lite. Lapack_lite.dll existed in the correct location, but running "cygcheck -c" (as per http://cygwin.com/ml/cygwin/2013-05/msg00361.html) on it revealed that it needed libquadmath0 which had not been installed. Numpy worked fine once I installed the missing libquadmath0 dependency. Is anyone else seeing this problem? Should this dependency be added to the numpy setup.hint?

Yaakov any hope for a libnss3-debuginfo?
Yaakov, The 64-bit version of rpm2cpio is SEGVing in this call: _nss_ctx = NSS_InitContext(NULL, NULL, NULL, NULL, NULL, flags); Is there any way that you could release a debuginfo package for nss? I could, of course, build it myself but I'd like to avoid that if possible. cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

But are you sure that the bug is in nss and not nspr? I wouldn't be surprised if I missed something in either of those two, but the latter seems more likely, and there is an nspr-debuginfo.

Actually, it was libgfortran3 that was missing a dep on libquadmath0, but only on x86. I fixed that on sourceware.

I can't tell where the bug is. I don't get a good backtrace. Wouldn't the NSS_InitContext mean it's in nss? cgf -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
