Re: [Doxygen-users] EXTERNAL: Re: Doxygen on Cygwin overwrites user defined paths

[Vega, L. A <lui...@lm...>]

My problem is not related to the RFE.  It is an issue with the Cygwin inserting the current path to pre-defined values.

For example if I set
PLANTUML_JAR_PATH = $(PLANTUML_HOME)   where PLANTUML_HOME is an environment variable with the appropriate location.

Under Linux, OSX and Windows,  PLANTUML_HOME will be kept the same value.   Under Cygwin the value is automatically overwritten to be $(PWD)/$(PLANTUML_HOME)

So if I set the $(PLANTUML_HOME) to C:/COTS/PlantUML,  the Cygwin version will convert it to /cygdrive/c/Development/MyProject/C:/COTS/PlantUML

If I set it to a cygpath (ie:, /cygdrive/c/COTS/PlantUML ), it will still override it to /cygdrive/c/Development/MyProject/cygdrive/c/COTS/PlantUML/plantuml.jar

No matter what value is or format is use, the Cygwin version of doxygen will always prepend $(PWD)/ to it.

Hope this helps.

Subject: EXTERNAL: Re: [Doxygen-users] Doxygen on Cygwin overwrites user defined paths

I filed a bug about relative paths in a doxyfile being relative to where doxygen is executed eons ago. See https://bugzilla.gnome.org/show_bug.cgi?id=756161. There has been no action. However I encountered the problem on macOS and I thought on other platforms too. Not sure why your results are different.

As for the cygwin path issue, either make sure all tools, including doxygen, are cygwin tools or all are windows tools. You might be able to do some mixing by using scripts that use cygpath.

When setting up the PLANTUML_JAR_PATH (an others path based config option) within the Doxyfile configuration, the Cygwin version of doxygen will insert the current directory path to the front of the user specified path.   This behavior is very specific to the Cygwin version (not how the Linux, Win or OSX versions of doxygen behave) and is problematic in many ways.

The Cygwin version of doxygen is assuming that all paths are relative to the directory where doxygen is executed.   This is completely opposite to the norm.  Different users have different environments, which is the reason why the Doxyfile includes options to define this paths in the first place.  Also, under Cygwin, we have a problem when doxygen calls external tools that don't support the unix-like cygpath (i.e., anything none-cygwin).  For example, when executing Java to run PlantUML even if the plantuml.jar file is stored a matching relative path, the execution would fail because of the unsupported path format.

Don't know if this is the proper place to submit a bug related to the Cygwin version of doxygen.   If not, please let me know where I should submit a bug report.
