Re: configure fails on checking ino_t
Hi Ken, thanks for this - both 32-bit and 64-bit Geomview from your repository work as expected. I was able to run SaVi (http://savi.sf.net/) under both, with OpenGL and piping between Geomview and SaVi working so that SaVi could control Geomview. (64-bit working with SaVi was a pleasant surprise - I had not been able to get piping between Geomview and remote control apps working previously in 64-bit, when compiling Geomview myself. And 64-bit OpenGL is good to finally see working, too.) However, Geomview's supplied modules aren't listed in the right panel of its main window, suggesting it hasn't been configured and built with xforms and with Tcl/Tk, which its modules need.

Re: CR-LF handling behavior of SED changed recently - this breaks a lot of MinGW cross build scripts
I just had to debug & fix a problem from the sed behavior change that has little to do with MinGW. I'm running a native version of Emacs and have makefiles, lots of scripts, and various commands in my makefiles for extracting dependencies. The commands use sed, gawk, ..., and started creating bad dependency files because of carriage returns showing up in the last field when filtering with sed & gawk. It took a while to track down, especially because the command was working properly when run directly in a cygwin terminal running bash, but gave different behavior when make ran the command from inside of Emacs. I could imagine this causing all sorts of trouble for people in general.

I agree heartily with this; the only Windows tool I use that is actually dependent on CR is notepad, and usually that is only for a lazy verification that CR is/isn't present Everything I've written for dealing with Windows CR infested outputs in *nix environments I strip all CRs as my first step, and do not put CRs in my output; so far no complaints from end users about the missing CRs. -- Erik -- 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

That begs the question: why are you doing a cross build in the first place? Cross building generally means that _no_ programs built for the target host may ever be run by the build scripts, because they simply won't work. Any attempt to do so is either a severe bug in the existing build setup, or the consequence of trying to coerce a build script that just cannot handle cross-building into doing it anyway. So you shouldn't even be getting to any place where the output of a cross-target (i.e. MinGW) executable is run on the build host, and its output piped into a build platform (i.e. Cygwin) tool. That means what you're trying to argue here is that an evident short-coming of some build setups should be fixed by breaking Cygwin pipes' mode of operation for everyone. Sorry, but I don't see that happening. Cross building on Linux would be much more complicated, because on Linux I would no matter what need 3 OCaml variants but also 2 Coq variants, because I need to compile the Coq libraries, so I need to run Coq on the build host as well. With cygwin I can call the MinGW variants. Indeed. That is a lucky _exception_ to what you can do in a cross build. But you have to pay a price for this unprecedented luxury. The price is that you have to massage the output of those MinGW programs to follow Cygwin rules, or change the way those MinGW programs are built to make them follow the rules by themselves. I don't see another way than having sed strip away the CRs. It doesn't make sense to build programs intended to be run under plain Windows such that they do not produce CRs.

RE: CR-LF handling behavior of SED changed recently - this breaks a lot of MinGW cross build scripts
Dear Eric, > Building mingw apps may be one use of cygwin, but it is not the "intended use > case". I said "an" intended use case, not "the". I also use cygwin for a lot of other things. > If you are writing a Linux app that processes data produced on a windows > machine, then YOU must strip CR from that data (Linux sed will NOT strip it). > So now cygwin sed does the same thing. Maybe my situation gets clear when I describe what my use case is: I maintain the scripts which build the Windows installers for Coq - a proof assistant with a GTK based UI. This starts building a MinGW OCaml compiler from sources. I could also build a host=cygwin target=MinGW OCaml compiler, to get around the issue that messages it produces contain CRs, but OCaml doesn't support host!=target very well, and many of the tools it produces I also have to run under cygwin. So I would need 3 OCaml compilers, one build=cygwin, host=cygwin, target=cygwin to build the tools I run under cygwin during the build, then one build=cygwin, host=cygwin, target=MinGW to build the tools I finally need for plain Windows. But since Coq also needs OCaml at run time I also would have to build a build=cygwin, host=MinGW, target=MinGW variant. Many of the tools and libs I need have similar issues. I admit I am lazy and build only one OCaml compiler, the build=cygwin, host=MinGW, target=MinGW variant, because I will need this eventually anyway. The only issue this results in is that its text messages (like version or lib path info) contain carriage returns. All the OCaml and Coq build scripts (and the build scripts for the libraries and tools I need) themselves are not maintained by me. I just maintain the wrapper which sets up a fresh cygwin, gets all the sources, builds the whole stuff and finally produces a Windows installer for others to use. I call many scripts and tools which are originally designed to run on Linux and are maintained by Linux centric people and I do not want to bother them with such issues. Cross building on Linux would be much more complicated, because on Linux I would no matter what need 3 OCaml variants but also 2 Coq variants, because I need to compile the Coq libraries, so I need to run Coq on the build host as well. With cygwin I can call the MinGW variants. All this did work remarkably well on cygwin, because cygwin had support to call MinGW programs and to process their text oriented output. I don't see another way than having sed strip away the CRs. It doesn't make sense to build programs intended to be run under plain Windows such that they do not produce CRs. It doesn't make sense to hack around in build scripts and source code of Linux centric tools just to get this Windows build done. The true way would be to support host!=target in OCaml and to make 2..3 host/target build variants of everything. But it would take ages, waste a lot of energy (think of the CI test severs), slow down development, ... and all this just to get rid of maybe 200 carriage return characters in strings communicated in a build process. For me, cygwin is a pragmatic tool to get the job done. And it does, perfectly and better than I expected when I started this, except that current cygwin's text tools can't process text produced by MinGW tools out of the box any more.

RE: CR-LF handling behavior of SED changed recently - this breaks a lot of MinGW cross build scripts
Dear Dan, > One could try making a wrapper shell script where sed usually lives that adds > those options and calls the real sed... I tried to do exactly this, but I tried to pipe a dos2unix command in between. It got a bit complicated because I had to parse the sed command line arguments. The solution of adding an extra command with -e is much more elegant. And you are right, replacing sed with a shell script is better than using an alias. But the -e method won't work for grep and for awk not in all cases.

Building mingw apps may be one use of cygwin, but it is not the "intended use case". The intended use case of cygwin is to emulate as much as possible of a linux environment.

I am building many open source tools and libraries which are maintained by others, and as you said, these others have every right to deny implementing windows specific workarounds in their tools or build scripts. Why should anybody use "wb" mode to open a file in a Linux centric app or mess around with the input of sed to remove CRs in a build script for such an app? Of cause the same is true for cygwin, except that I think building MinGW apps is an intended use case for cygwin. But then it needs to have ways to deal with MinGW programs which behave like MinGW programs should, and this means ending lines with cr-lf.

If your makefiles configured SED you could use: export SED='sed -b -e '\''s/\r$$//'\''' and that is probably the best approach: change sed to SED in makefiles, and configure SED=sed if not set. Alternatives: alias sed='sed -b -e '\''s/\r$//'\''' sed(){ /bin/sed -b -e 's/\r$//' "$@"; } sed -i 's|\|& -b e '\''s/\r$//'\''|g' ... to patch files - double the "$" to patch makefiles, or build and use a Mingw(-compatible) sed that converts \r\n to \n on input and \n to \r\n on output? -- Take care.

RE: CR-LF handling behavior of SED changed recently - this breaks a lot of MinGW cross build scripts
Dear Blake, > External products were being lazy by relying on cygwin to strip CR when they > should have stripped it themselves. But 'sed -b' does NOT strip CR (it is the > exact opposite, of keeping CR unstripped). I think that there are more people who use sed for text processing in a MinGW cygwin cross environment than there are people using sed for binary data - but looking at the mailing list this might be a subjective view. The maintainers of the Linux centric SW could insert dos2unix in all stuff piped into sed, but this would only be required in this very specific build configuration, and Linux SW maintainers frequently argue why they should care about Windows at all. It can take all sorts of philosophical discussions to get such a change in. And I cannot blame them for a "we are free SW people, if you Windowers can make use of our SW without bothering us - go ahead, but please don't drag us into your mud" attitude. In the end one usually gets it done, but the effort is not negligible. I think that sed, grep and awk are in the end text processing tools, and that they should at least have an environment option to behave like text processing tools in a mixed cygwin MinGW environment. With sed I have several 100 issues building a single application, with grep it was just one in my scripts which I fixed. awk no issues so far. Btw.: I don't think that it will be easy or even possible to build detection for MinGW generated output into the cygwin dll as you suggested in a previous post. How should the receiving part of a pipe know what kind of DLLs the sending part has loaded? One could have obscure heuristics to detect "text with cr-lf line endings", but this sounds more like a night mare than a solution. The only entity who could detect this is the shell, but then you have more than one shell (and more philosophers). As I said, I think on cygwin sed, grep and awk should have an environment option to be MinGW friendly text processors (as they used to be). Other less text centric SW should be unaffected. Honestly my solution to the problem is to build sed from sources with CR stripping. I thought about it a day and came to the conclusion that everything else is a waste of time.
