Hi Alessandro.
Your solution is exactly what I had in mind as a backup solution if I could
not find a bulit-in solution, as it involves additional tools – you run a
makefile to set the project version, which means, it won’t work in the case
that one starts doxygen directly without involving that makefile. I was
looking for a solution that does not have this restriction.
Kind regards,
Stefan.

from a header file
Hi, Stefan
I faced this problem years ago and the solution I came up was to add a
target in my Makefiles where I also set variables with the the project
version.
MAJOR_VERSION = 1
MINOR_VERSION = 10
BUILD_VERSION = 155
VERSION_NUMBER = $(MAJOR_VERSION).$(MINOR_VERSION).$(BUILD_VERSION)
Then I added a target with the following command line:
docs : $(HTML_DIR)
( cat doxyfile; echo "PROJECT_NUMBER=$(VERSION_NUMBER)" ) |
doxygen -
That command generates the documentation with the version number defined in
the Makefile that is also used in the the header variables inside the
project.

Hi.
I would like to centralize the versioning of a project to avoid having to
count up the project version number at multiple places all the time.
I have version.h file, which looks like this:
#define STRINGIFY2(param) #param
#define STRINGIFY(param) EG_PHOTON_STRINGIFY2(param)
#define VERSION_MAJOR 4
#define VERSION_SERVER_MINOR 1
#define VERSION_CLIENT_MINOR 8
#define VERSION_PATCH_RELEASE 2
#define VERSION STRINGIFY(VERSION_MAJOR) "."
STRINGIFY(VERSION_SERVER_MINOR) "." STRINGIFY(VERSION_CLIENT_MINOR) "."
STRINGIFY(VERSION_PATCH_RELEASE)
- the resource-files include this header, so that the Visual Studio
resource compiler can use it for the version number that is shown in the
details page of a generated dll
- the build-scripts parse that file, so that they can include that number
as part of the name of the generated package
- the code itself also includes this header so that it can send the
version to the server when connecting
Now I wonder about the bst way to also have doxygen use this version
number when generating the documentation.
As a fallback option I could just have the buildscript parse in doxygens
configuration file and replace the value to which PROJECT_NUMBER is set
with the value from that header that the build script already has
available anyway, before running doxygen.
However that would mean that only after running a script first, doxygen
would know the correct version number to use.
I would prefer if doxygen would also know the correct version number
without the need to run an external tool first.
Is there any way how to tell doxygen in its config file to read out the
version number from a #define in a header file?
I know that it's possible to set PROJECT_NUMBER to an environment variable
instead of a hard coded value, but that doesn't help as we still would
have to update the env var every time when version.h gets updated, which
is errorprone.
So is there any way to have doxygen use the value of a #define for the
version number in the generated docs without using any external tools?
Kind regards,
Stefan.
