git tries to stat //HEAD when searching for a repo, leading to huge delays on Cygwin

阅读更多关于 git tries to stat //HEAD when searching for a repo, leading to huge delays on Cygwin

问题 I have a fancy shell prompt that executes git rev-parse --is-inside-work-tree to determine whether we're currently inside a working directory. This causes git to walk up the directory hierarchy looking for a containing git repo. For example, when invoked from my home directory, it stats the following paths, in order: /home/me/.git /home/me/.git/HEAD /home/me/HEAD /home /home/.git /home/.git/HEAD /home/HEAD / /.git /.git/HEAD //HEAD The last name ( //HEAD ) interacts badly with Cygwin, which

fflush(stdin) does not work compiled with gcc in cygwin but does compiled with visual studio 2010

阅读更多关于 fflush(stdin) does not work compiled with gcc in cygwin but does compiled with visual studio 2010

问题 I am (re-)learning programming and I started with C. My IDE (if I may say so) is cygwin (32Bit) and Visual-Studio 2010 both on Windows7. I am always compiling the code I write with gcc (cygwin) as well as with the VS2010 compiler. I do so, I guess, because I think it is a good way of learning. Anyway I just learned about fflush(stdin), i.e. flushing the stdin buffer. Seems a good functionality because else, using scanf appears to be a pain. So I wrote the code below based on an example from

问题 I'm trying to start WildFly 8.2 under a user that doesn't have permissions to write in a WildFly home directory and it's subdirectories. For this purpose I've copied standalone directory to a user home directory. Here is a command I use to start WildFly in cygwin: $ /cygdrive/c/Program\ Files/wildfly-8.2.0.Final/bin/standalone.sh -Djboss.server.base.dir='C:\Users\above_mentioned_user\standalone' -c standalone.xml And here is an output of this command: cygpath: can't convert empty path =======

Convert char to lowercase in batch

阅读更多关于 Convert char to lowercase in batch

问题 I am having trouble trying to convert a windows path into the cygwin-style linux like path. C:\path\to\file will be /cygdrive/c/path/to/file for instance. I have everything working except for converting the uppercase drive letter pulled out of the path to lowercase. The link everyone gives for these questions is: http://www.robvanderwoude.com/battech_convertcase.php and the for loop under "SET, Take Two" seemed the most appropriate. This is what I have so far: @ECHO OFF SETLOCAL

问题 I'm trying to get the gfortran compiler with cygwin. When attempting to compile a hello world program, I get the following error: gfortran: fatal error: -fuse-linker-plugin, but cyglto_plugin.dll not found compilation terminated. To install the compiler, I used the cygwin setup and selected gcc-fortran: GNU compiler collection libgfortran3: GCC fortran runtime library I also mistakenly selected the toolchains for mingw, even though I don't have the mingw compiler (as far as I'm aware). g++,

问题 Trying to make a CLI type program - waiting for user input. In Cygwin, the script just exits. Just this in the script process.stdin.resume() Seems to work on a Linux VM. Works on Windows Command line also. Im assuming 'terminal' stuff regarding Cygwin.. 回答1: The symptom is that Cygwin process.stdin.on('data', cb); and process.stdin.on('end', cb); doesn't get called. I found a workaround for it Versions > ver Microsoft Windows [Version 6.1.7601] $ uname -a CYGWIN_NT-6.1 localhost 1.7.28(0.271

Python's subprocess does not interpret “~” as expected on cygwin

阅读更多关于 Python's subprocess does not interpret “~” as expected on cygwin

问题 Section 17.1.1.1. of the documentation states: If shell is True, the specified command will be executed through the shell. This can be useful if you are using Python primarily for the enhanced control flow it offers over most system shells and still want convenient access to other shell features such as shell pipes, filename wildcards, environment variable expansion, and expansion of ~ to a user’s home directory. However, on cygwin , output from bash isn't the same as from Python's subprocess
