I have imported the veins_inet subproject when importing the veins 4.5 project (by selecting the "Search for nested projects") in Omnet++. I have built veins and can run the Erlangen example.

However, I cannot build the veins_inet project. The sources can be found here: https://github.com/sommer/veins/tree/master/subprojects/veins_inet
I get the following error:

make MODE=debug all 
make[1]: Entering directory '/home/XX/omnetpp-5.1.1/samples/veins/subprojects/veins_inet/src'
veins_inet/VeinsInetManager.cc
veins_inet/VeinsInetManager.cc:21:41: fatal error: veins_inet/VeinsInetManager.h: No such file or directory
compilation terminated.
Makefile:97: recipe for target '../out/gcc-debug/src/veins_inet/VeinsInetManager.o' failed
make[1]: Leaving directory '/home/XX/omnetpp-5.1.1/samples/veins/subprojects/veins_inet/src'
Makefile:12: recipe for target 'all' failed
make[1]: *** [../out/gcc-debug/src/veins_inet/VeinsInetManager.o] Error 1
make: *** [all] Error 2

It seems like the header files have failed to be included.

I can bypass the "No such file or directory" errors by manually copying all necessary *.h files into the veins_inet/src/veins_inet folder and editing the *.cc and *.h files, such that the compiler finds the required header files.
I guess the issue lies in the Makefiles, or rather in the configure file, which generates the Makefiles.

  • Looks like a bog-standard problem with the headers not being installed in the standard `include` directory, or in whatever location that the `configure` adds as a `-I` path to the `Makefile`. There is no point telling us that you guess the issue is in those files, without posting what they are. – underscore_d Jun 06 '17 at 09:03
  • OK. Added the content of configure and Makefile files. – zanlik Jun 06 '17 at 09:12
  • I managed to build the project successfully by modifying the veins_inet/src/Makefile as follows: INCLUDE_PATH = -I/home/XX/omnetpp-5.1.1/samples/veins/subprojects/veins_inet/src/ -I /home/XX/omnetpp-5.1.1/samples/veins/src -I /home/XX/omnetpp-5.1.1/samples/inet/src. But how should the configure file be modified to reflect those changes ? – zanlik Jun 06 '17 at 09:43
  • Probably it should not, because the project's build setup should be left as the project intended it to be, and if you need to do other things with other paths, you should override that locally rather than hacking on the project's own files. So, you should use a site file or `-I` arguments added to your `configure` invocation. See https://stackoverflow.com/questions/7467910/with-autoconf-automake-how-do-i-specify-include-file-paths of which this is probably (now) a duplicate. – underscore_d Jun 06 '17 at 09:49

    Thanks for your help. I added those paths in the following place: Right-click on veins_inet project >> Properties >> Omnet++ (down arrow) >> Makemake >> select src:makemake.... >> click Options >> Go to Compile tab >> include the 3 required directories...in my case: /home/XX/omnetpp-5.1.1/samples/veins/subprojects/veins_ine‌​t/src /home/XX/omnetpp-5.1.1/samples/veins/src /home/XX/omnetpp-5.1.1/samples/inet/src These will be added during the compilation time. Problem solved. Thanks! – zanlik Jun 06 '17 at 10:16
  • Cool, glad you get it working, thanks for letting me know! – underscore_d Jun 06 '17 at 10:31

To solve the problem I had to add missing "Include Paths" to the project properties:
1. Select your veins_inet project and click Project>>Properties in Omnet++
2. In the new window expand the OMNeT++ entry and select Makemake
3. select src:makemake(deep,recurse)-->veins_inet(dynamic lib)
4. Click on the Options... button
It should look like this: Properties for veins_inet window
5. Go to the Compile tab in the window that opens
6. Enter the missing include directories:

[workspace]/veins/subprojects/veins_ine‌​‌​t/src
[workspace]/veins/src
[workspace]/inet/src

You should end up with something similar: Makemake Options window
7. Click OK in both windows
8. You should be able to build the veins_inet project without errors

if you use omnet++ 5.0 version : IDE Project->properties->OMNET++ -> Makemake -> select src -> build makemake selected options button -> compile -> check [add all source folders under this deep makefile] :: then refresh and build project ..
