Why does pandoc have troubles with certain paths on cygwin? - cygwin

I have installed pandoc.exe 2.10 with the Windows installer, and I am calling it from cygwin 3.1.6-1. Unlike most other commands, pandoc seems to have troubles with certain paths. I get an error “openBinaryFile: does not exist (No such file or directory)” when the input or output file paths include one of the following:
A ~, e.g. ~/myfile.md.
A /cygdrive, e.g. /cygdrive/c/Users/me/myfile.md.
A network drive, e.g. //server/path/myfile.md.
By contrast, paths that include the following work:
A drive letter, e.g. c:/Users/me/myfile.md.
Paths relative to the current directory, e.g. ./myfile.md or simply myfile.md.
Network drives with backslashes, e.g. \\server\path\myfile.md.
Why is that? Why is pandoc’s behaviour different from other commands?
Most Google hits for the error message relate to R Markdown. In the JDK build-dev mailing list, the problem was related to pandoc not being a native cygwin app (see CR: 8180540: Add pandoc build fix for windows).

As /u/matzeri has said (thanks!), it is because Windows pandoc is a Windows program and does not recognize Cygwin path styles.
A reliable way to fix this might be using cygpath with the --absolute and --mixed flags, like so:
pandoc "$(cygpath -am path/to/file.md)" -o "$(cygpath -am path/to/other_file.html)"

Nodejs terminal script problematic cygwin paths of arguments - cannot make an universal script

I have an issue with using node.js as a script language in the Cygwin terminal. The script is used not only on Cygwin, but also on other platforms like OS X or GNU/Linux (no issue there).
Local or absolute path arguments to the script are passed as Cygwin paths (example: /cygdrive/c/Users/username/Dir/some-file.txt), but node requires Windows path (example: C:\Users\username\Dir\some-file.txt).
There is a tool cygpath that is used to translate between the two, but because of the multiplatform requirement, I cannot hardcode them. I would not like to make any bash wrappers so I can keep it a one file script.
For example this would work: ./script $(cygpath -w /tmp/file), but I cannot require the users of the script to put cygpath every time they want to use it.
Node is installed as the windows binary and is invoked with a shabang: #!/usr/bin/env node. which nodejs yields /cygdrive/c/Program Files/nodejs/node.
TL;DR: is there any sane and portable way to trigger automatic path translation in Cygwin for arguments of a nodejs script?

cygwin binary exec format error

I have a script file that I was given to run in windows using Cygwin. When I try to use this file I get the following error
-bash: /sigdet/filename: cannot execute binary file: Exec format error.
sigdet is the folder within the Cygwin directory that I have the script. Rawdata is the name of the directory with the raw data files that the script is supposed to analyze.
To try and solve this, I have changed the file permissions, I have checked to make sure that it is on a 64 bit machine and the script appears to have compiled on a 64-bit machine. After these steps, I don't know what else the problem could be. Here are the commands I've entered:
I first changed the directory like so:
$ cd /sigdet/
Then I ran the script that is suppsed to work:
$ /sigdet/filename -i rawdata
Does the script file need to have an extension in windows? I've tried changing it to a .sh extension with no luck. I'm told that it just works on other windows machines just how it is.
Thanks to anyone that can help with this.
Your file is not an executable. It most probably contains ELF executable which is designed for Linux operating system, or it's corrupt.
If your file was a shell script, or in fact anything that contained plain text, you'd get different errors (such as, "expected command name" or "unknown command: XYZ" etc.)
Scripts are not supposed to have file extensions, like any executables. On the other hand, they should have shebangs: small text located in the first line that tells the system the path to the interpreter. For example, a Python executable script might be named whatever and have #!/usr/bin/python3 or similar in the first line. When you run it through ./whatever in the shell, it'll look for python3 in /usr/bin and run your file like this: /usr/bin/python3 ./whatever. (In fact, thanks to this you can also specify additional parameters that get passed to the interpreter.)
There is also a chance that your script is valid, but it contains a shebang pointing to bad interpreter. If that is the case, then most likely the path is correct, otherwise you'd get /whatever/interpreter: bad interpreter: no such file or directory error or similar. But then, all the other points apply to the interpreter (which is just another executable...)
If the script and/or interpreter was meant to be executed on Windows or Cygwin at least, it should either contain aforementioned shebang (#!/path in the first name) or it should be Windows executable (in which case the file data should begin with MZ letters, you can inspect it in notepad.) If it isn't, it means the files you were given can't run on Cygwin.
Had this same problem. Added the following at the top of makefile:
export ARCH = CYGNUS
What happened during the make process is that Linux and Windows versions of the executables were created. You just have to use ./.exe versions.
In my case, I got the error when I used a wrong command to compile my C program. When I used the right command:
gcc myprog.c -o myprog.exe
the error was resolved.

Can't use "." to execute files with cygwin

I recently installed Cygwin on Windows 8.1, it works great but I can't execute file using the dot, for example "./hello.ml". I'm using the Windows's command prompt.
When I try using it, it show me that "." is not reconized. How can I make it works ?
Thanks.
You need to use the cygwin terminal or powershell instead.
The command interpreter doesn't think that your files are executable because they aren't one of the types that are recognized as binary executables. In general, Windows would use file associations from the registry to make things happen when you try to run a file. The cygwin terminal follows the unix-like convention and knows that your scripts are ml files and they are executable by using the ml interpreter, most likely from a #! at the top of your file.

Troubles installing Haskell Platform

I was trying to to install Haskell Platform 2014 2.0 but I can't really understand what am I supposed to do to make it work and there seems to be no useful documentation on the site.
I downloaded the binary dist from the site, unpacked it, launched the 'activate-hs' script and got this:
Haskell set to:
GHC /home/riccardo/usr/local/haskell/ghc-7.8.3-x86_64
Haddocks file:///home/riccardo/usr/local/haskell/ghc-7.8.3-x86_64/doc/frames.html
Other doc file:///home/riccardo/usr/local/haskell/ghc-7.8.3-x86_64/share/doc/ghc/html/index.html
Symlinks for command line tools (ghc, cabal, etc..) added to:
/usr/local/bin
Even running in --verbose tells me nothing more about what's going on, it just returns a list of all the files.
What should I do?
EDIT:
riccardo#eos:~$ whereis ghc
ghc: /usr/local/bin/ghc
If I go to /usr/local/bin the symlinks are there and they point to the respective files in /home/riccardo/usr/local/haskell/ghc-7.8.3-x86_64/bin, but in the property window it says they are broken, what does this mean?
Also, if I get into home/riccardo/usr/local/haskell/ghc-7.8.3-x86_64/bin and try to launch the scripts directly from there, it still won't work:
riccardo#eos:~/usr/local/haskell/ghc-7.8.3-x86_64/bin$ ./ghci-7.8.3
./ghci-7.8.3: line 2: /usr/local/haskell/ghc-7.8.3-x86_64/bin/ghc-7.8.3: File o directory non esistente
File o directory non esistente = file or directory does not exist
For posterity, if you're installing the generic-linux binary package as this appears to be describing, you cannot just run activate-hs. Rather you run install-haskell-platform.sh which puts everything in the proper place. Following that, you can use the installed activate-hs in the future if you want to swap between different versions...

Cygwin make error : *** target pattern contains no `%'

I got this error while (re)building, using cygwin make.exe version :3.81.
Error : *** target pattern contains no `%'.
This error is due to a presence of a ":". Therefore it no longer supports windows paths.
You need to download version 3.80 and replace the make.exe in the \bin directory.
Apparently it needs cygintl12.dll too.
rollback to make 3.80 (Geant4)
cd /usr/bin
mv make.exe make_381.exe
wget http://geant4.cern.ch/support/extras/cygwin/make.exe
chmod +x make.exe
install libintl2 from cygwin setup for the required cygintl-2.dll
I got the same error when trying to build a project on Linux or OSX, that was previously built on a Windows machine and had some .o.d files hanging around in the output folder.
Once I manually deleted the .o.d files the problem was resolved. Apparently the "Clean" command of my IDE (CodeLite in this case) wasn't deleting the .o.d files.
Most likely due to the presence of a colon following a drive letter. For example consider
build : $(NativeHeaders)/*
If
NativeHeaders=../../../cpp/generated
then all is well, but
NativeHeaders=C:/dev/folder/cpp/generated
results in the error that you get.
I was getting this error because I didn't have a Tab (\t) character at the beginning of my commands. I had expandtab in my vim set so it was replacing a tab character with 4 spaces. When I turned that off and changed spaces to a tab it was fixed
I had the target pattern contains no '%' error while building with the Android NDK using cygwin.
I found the following link helpful:
Errors Generated by Make
‘missing target pattern. Stop.’
‘multiple target patterns. Stop.’
‘target pattern contains no `%'. Stop.’
‘mixed implicit and static pattern rules. Stop.’
These are generated for malformed static pattern rules. The first means there’s no pattern in the target section of the rule; the second means there are multiple patterns in the target section; the third means the target doesn’t contain a pattern character (%); and the fourth means that all three parts of the static pattern rule contain pattern characters (%)–only the first two parts should. If you see these errors and you aren’t trying to create a static pattern rule, check the value of any variables in your target and prerequisite lists to be sure they do not contain colons. See Syntax of Static Pattern Rules.
And so, my solution included changing my system variables from Windows format to Unix format like so:
Instead of C:\Android\android-ndk-r10c, I used /cygdrive/c/Android/android-ndk-r10c for the NDK path.
Similarly, I changed the NDK project path to /cygdrive/c/Android/project/src/main/jni.
In my case I was using CMake under Cygwin when I got this error. It turned out the Windows version of CMake was executed. Subsequently, Windows paths were used in the make file. I installed Cygwin's version of CMake through the setup program and got it working.
I had this problem on Linux when the build directory contained a ":" caused by doing a mercurial checkout which created a directory named "server:port".
I had to change the following in my make file to be compatible with Make_381:
before:
ARDUINO_BASE_DIR = C:\programs/arduino
now:
ARDUINO_BASE_DIR = \\programs/arduino
Try this if you're running Eclipse C/C++ and referencing files from Cygwin under Windows, make sure c:/cygwin/bin or c:/cygwin64/bin comes after your preferred compiler tools in your Windows Path environment.
Example:
Path = ;C:\yagarto\bin;C:\yagarto-tools\bin;C:\cygwin64\bin;
After making the changes, exit Eclipse and restart for it to take effect (simply restarting Eclipse without exiting won't fix the problem.
In my project, obj folder was probably corrupted and I was getting this error. Manually deleted obj folder. Then ndk-build completed fine.
