Summary0000966: "Generate NED documentation" crashes due to broken pathname under Windows
DescriptionI was trying to generate the documentation for one of the samples (dyna) via "Project->Generate NED Documentation" but I got the following error:

An internal error occurred during: "Generating NED Documentation...".
org.omnetpp.common.util.ProcessUtils$ExecException: Process exec error for C:\Users\XXX\Documents\usr\lib\omnetpp-5.0\tools\win32\usr\bin\doxygen.exe (exit code 1) : error: Failed to open temporary file /c/Users/XXX/Documents/usr/lib/omnetpp-5.0/samples/dyna/C:\Users\XXX\Documents\usr\lib\omnetpp-5.0\samples\dyna\doc\doxy/doxygen_objdb_3808.tmp

Based on the output, it looks like the problem is due to the pathname being passed to doxygen is ill-formed, containing both mingw32- (/c/Users/...) and Windows- (c:\Users\...) -style pathname.

I've tried with other projects too, obtaining the same results.

Let me know if you need any more information.

Dear paolinux,

I believe that I actually just solved this issue.

So OMNET++ comes with Doxygen, but it turned out that the version was out of date. I ended up downloading the newest version of Doxygen, and replacing the existing doxygen.exe file with the most up-to-date version (at the time of this post, it was found here: [^])

I hope this helps any future users out! It took me quite a while to figure out.

Hi Van,

thanks a lot for your input and apologies for the delay in getting back to you.

I've tested your solution on my end and I can confirm that it fixes the problem. I still hope this issue will be addressed in the next release of omnetpp, without requiring the external dependency but for the time being it's a great workaround.

Thanks and merry Xmas,

We should use mingw version of doxygen and dot (instead of MSYS). MSYS version cannot understand the Windows style path in configuration file

The IDE now configures the doxy.cfg using relative directories so differences between the handling of Windows/Unix specific directory formats will no longer be a problem.
