[Lazarus] Developing on Linux with files on Windows NTFS [NOT Fully Solved]
There is still one residual problem. Right now I am developing and testing on Linux with the files on NTFS using ntfs-3g with case sensitive file names. Everything seems to be ok until I get a compilation error at which point I get two editor windows pointing to the same file with tabs showing: MyFileMyFile(2) If I re-compile, a window pops up telling me that the file on disk has changed and asking if I would like to reload. If I press reload I get the modified file, else I get the file from before the compilation error. Strangely, the compilation error will re-occur even with the modified file showing in the source editor and the unmodified file closed in the source editor. It doesn't seem to matter if I use file-contents or file timestamp to determine the modification state of the file. Also, I have looked on the disk and see only the MyFile.pas, never MyFile(2).pas. There is a simple work-around (which might give someone a clue as to the cause). If I explicitly save the modified files before starting compilation the problem never occurs. (I just have to remember to do it ;-) ). This never occurs when the files are on the Linux ext4 file system.

Re: [Lazarus] Developing on Linux with files on Windows NTFS {Solved]
Thanks to all who responded to my plea for help with multi-platform development. It seems that I was mistaken about the time-stamps causing the problems I encountered. The problems were caused by the fact that Lazarus for Linux wants case sensitive file names and the NTFS driver I was using was case insensitive. The erroneous behavior that I was seeing was due to capitalization in unit names, not time-stamps. The solution (as suggested by John Landmesser) was to use ntfs-3g (I put it into fstab and added my own uid/gid to avoid permission problems. fstab would not have been the proper solution if there were more than one user on the computer). I also took the suggestion to use separate directories for the windows and linux project files. This separated the object and executable files between the two systems as well. I also found a windows driver for ext4 that does not corrupt the ext4 file system. It is available from Paragon Software (free for personal use, reasonably priced for commercial use). It was suggested that I use svn for file sharing between windows and linux. I actually use git for all my source control, but it did not solve the mixed case file name issue that was actually causing my problem between the two OSes. Again, many thanks for all the great help.
