Mysteries of Cygwin…

cygwin and its mysteries to bring Linux software to Windows
I am using my wife’s XP machine a lot after work and hope to compile kdissert (a mindmap tool) for cygwin. It works on coLinux for me already (which you should also discuss) but I felt like not booting something extra.
My effort ended before it really started …. a file aux.h could not be untared. Google told me that this was a special problem with Windows as aux.[ch] are reserved names. This is hillarious.
Pleeze … fix this behaviour and … give me kdissert.
This is a common problem when porting applications to a Win32 as AUX is one of the few reserved filenames. Other reserved files, regardless of extension, are AUX, LCOMn, CON, LPTn, NUL, and PRN. (a lower case n represents a digit, so LPT1 or LCOM2 would be reserved names) The only good workaround is to rename the reserved filenames.
I took a quick look at the kdissert source and found aux.h is only included in 22 files. I would suggest renaming aux.h to something else like kdissert_aux.h and either manually editing the source files or use sed (or enter your stream editor of choice) to make it a little less painful.
Great you say, buy how do you rename or extract a file from an archive if Windows won’t let you create it in the first place? Tar just hangs when it gets to the aux.h file from kdissert-1.0.6pre3.bz2. The easiest solution would be to rename and modify the source on a separate Linux machine or VPC. However, if all you have access to is a Windows machine with Cygwin, you can still work around this problem.
Extract out the contents of aux.h to another file using tar.
$ tar jxvf kdissert-1.0.6pre3.tar.bz2 –to-stdout \ kdissert-1.0.6pre3/src/kdissert/datastruct/aux.h > kdissert_aux.h
Make sure to exclude aux.h when un-tarring so tar doesn’t err out
$ tar -jxvf kdissert-1.0.6pre3.tar.bz2 –exclude \ kdissert-1.0.6pre3/src/kdissert/datastruct/aux.h
Copy kdissert_aux.h to the correct place
$ cp kdissert_aux.h kdissert1.0.6pre3/src/kdissert/datastruct/kdissert_aux.h
Modify the source files to use the newly named kdissert_aux.h.
This should at least get you started towards porting kdissert to Win32/Cygwin. You also might want to check out and keep an eye on KDE’s native Windows development, since further development of KDE on Cygwin has stopped.
