Emacs NT would be a native Windows build of Emacs, so is definitely organized to interact properly with Windows subprocesses. The Cygwin versions are designed to interact most easily with Cygwin subprocesses. They can probably be made to work with Windows subprocesses, but as you found, there is at least one rough edge here. My first guess would be something to do with line endings as they are conveyed back to the parent Emacs - the Windows "extra" CRs may confuse a Cygwin Emacs if it is not expecting them. We sometimes see this with bash scripts brought over from Linux to Cygwin. Anyway, this, or other character set related things, is where I would start to diagnose the issue and try different settings. I would ask questions around what the terminal settings are that the subprocesses see, what exact characters are they outputting, etc. Other are more expert than I in these details and may have specific settings to suggest that you look at :-) ...

Cygwin 3.1.x and later enables pseudo console for non-cygwin apps. Pseudo console generates some ANSI escape sequences if non-cygwin apps are executed. However, emacs provides dumb terminal for M-x compile, M-x shell or M-x eshell. As a result, the problem occurs. CYGWIN=disable_pcon disables pseudo console, so it will resolve the issue. -- Takashi Yano -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple

gettext util msgfmt error (javac: subprocess failed)
Hey everyone, I have a .po file I created and I wanted to translate that into a java ResourceBundle properties file. There is a util to do that via something like: msgfmt --java2 -d . messages_fr_FR.po But i got an error saying to set JAVAC or install gcj... javac is in my java/bin PATH env variable, and in cygwin I can standalone call javac fine... just seems like cygwin's msgfmt has trouble calling it... I read this tutorial http://xmlguru.cz/2006/10/saxon-gettext which is only webpage i see related to my problem so i did as the steps said. I created a wrapper javac.sh file like state and exported JAVAC in my .bashrc ... I re-ran and got the following message: msgfmt: /home/ahojat/bin/javac.sh subprocess failed Not sure whats wrong, i tried pointing to my 1.5 and 1.6 jdk javac.

It says: /home/ahojat/bin/javac.sh: line 2: /cygdrive/c/Program: No such file or directory I realized i needed to add a \ because of the space in Program Files; so java.sh file becomes: /cygdrive/c/Program\ Files/Java/jdk1.5.0_22/bin/javac.exe $1 $2 $3 `cygpath -w -p $4` But now when just running simple compilation test on ClassTest.java again says: msgfmt: /home/ahojat/bin/javac subprocess failed Frustrating :( -- 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

I remember trying, way back when, to provide a checking malloc library on Windows, and then discovering that there was *no* way of intercepting malloc() calls *inside LIBC itself*. In the Windows PE world (unlike the ELF world), a call to a routine that lives inside the same DLL is automatically bound to the local copy without any way to hijack the call. Thus there's no way to play games with LD_LIBRARY_PATH (or PATH, rather) to load a malloc that'll hijack all calls successfully. And there's definitely nothing like the LD_PRELOAD mechanism to wrap existing pre-linked programs to inject support libraries into the lib list. So any CreateFile calls inside the windows libraries would always go to the built-in CreateFile. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

RE: javac on cygwin
David, Thanks for considering this. The only real way to identify major (and minor) issues, however, is testing, so, hopefully, people will use these scripts. Once they are deemed reasonably robust, it might even be worth it to release a java wrapper package for Cygwin... Actually, the custom java.io.File wrapper is very useful in that it's orthogonal to the purpose of my scripts and takes care of one of the caveats (namely, the filenames passed to Java programs). It might be a good idea to post that code along with the scripts (there must be some tricks one can play with the CLASSPATH to transparently substitute the real java.io.File with the wrapper, so the programs don't have to change).

RE: javac on cygwin
Igor: Actually, the custom java.io.File wrapper is very useful in that it's orthogonal to the purpose of my scripts and takes care of one of the caveats (namely, the filenames passed to Java programs). Actually, the way it works now, the programs I write have to be Cygwin-aware (I don't have a java.io.File substitute -- I have an inonit.cygwin.File class which can represent a Windows or UNIX-style path). However, as you mention, it's at least occurred to me that the entire java.io.File class could be re-implemented with Cygwin-aware functionality and then could be used in preference to the java.io.File class by putting it in front of rt.jar in the -bootclasspath (at least on JDK 1.2 and later). One would probably also have to change FileInputStream and other classes -- I haven't looked into it extensively. -- David. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/

Re: javac on cygwin
Kevin, Javac is not particularly special. It is a Windows-native program, and as such requires absolute file and directory names be provided in Windows format (forward slashes are OK, but drive letters are required and the Cygwin notion of root is completely unknown to such programs). PATH-like variables (specifically CLASSPATH) must be in Windows format (semicolon separators). Both of these conversions is handled by the cygpath utility. Learn about it. I strongly suggest that if your development environment, either individually or as a group, is or is at all likely to become cross-platform (betwen Windows and any kind of Unix), that you adopt a Unix-centered set of build scripts and then create cover scripts that encapsulate the operations that bridge the gap between the POSIX / Unix world of Cygwin and the underlying native Sun Java SDK tools. Do so in a way that allows those translations to be easily switched off, replaced or made null when not needed (when you're working on an actual Unix system). I do lots of Java under Windows with Cygwin and have for quite a while. Feel free to come back with further questions.

I remember speculating at one point about creating wrappers to the win32 functions like CreateFile, MoveFile, etc. which would understand cygwin paths. You could theoretically modify an .exe to load cygwin1.dll and use the wrapper functions. Or you could use some of Windows hook facilities to do that. I don't think my idea met with much enthusiasm when I mentioned it, but I always thought it would be an interesting exercise. It wouldn't help for programs which actually do parsing on input file specs outside of the standard Windows API, though. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
