vterrain and openFrameworks

advanced
#1

hi to all, i’m trying to develop and addon based on vTerrain software http://vterrain.org/ , with which you can import maps terrain from DEM or other sources (and even custom made maps…) i can explain or better i can do a little tutorial for this. Bu t the reason of this thread is another. I receive an error while i compile the code because i think there is some C files that need to be excluded from source. I’m working on linux 64bit Ubuntu 12.04 , but i tested also in windows with VS2010 compiler. It was easier to solve in VS2010 because you can exclude the files from properties windows, but it’s a bit harder for me with makefiles. I tried with EXCLUDE_FROM_SOURCE but i get the same error. What’s wrong here?
this is the error that i receive:

attached you can find the file build.make from cmake vterrain project to have an idea on hw should be

build.make.txt

#2

may i exclude from source files with EXCLUDE_FROM_SOURCE in OF 0074 master branch?

#3

At least i did a succesful build in VS2010. I can explore the Simple.xml terrain of the example. but for now without the vterrain mouse and key support. if you want to try it, you need also the ofxOpenSceneGraph addon otherwise you will fail to load a scene( because vterrain lib is based on OpenSceneGraph ,libMini and GDAL). I had to modify ofxOpenSceneGraph due some changes in the ofEvents class of OpenFrameworks. I will upload the new changes on my repo. I think i will develop on Windows for now ( i will prefer on linux…). Next step is to develop a ofxAppVTerrainWindow to have keyboard an mouse support directly from vTerrain.

#4

updated the ofxOpenSceneGraph addon to the new changes in ofEvent. You can find here: https://github.com/kalwalt/ofxOpenSceneGraph/tree/develop

#5

it seems that EXCLUDE_FROM_SOURCE dosen’t works. Today i tried again to exclude some files from the build process but without success. i create a folder named “exclude” and added in config.make

EXCLUDE_FROM_SOURCE = “bin,bin,.xcodeproj,obj,src/xmlhelper/exclude”

but also this dosen’t exclude them from build. ( basically i renamed the folder from “include” to “exclude”)

this is the log:

so this doesn’t make any difference.

I’m wondering if i’m wrong with the path(id est: src/xmlhelper/exclude/) ( src is in my folder project) or there is something else. Please give me some advice for this!

The other option is to build the project without makefile. I tried today. I solved that above error , but i got others because OF has a lot of dependencies, In this sense could be very useful if someone has a ready project for codeblocks linux64 .

Many thanks to all.

#6

Now it’s possible also in Linus Os . But for the issue explained above i have to build a codeblocks project without the makefile. This makes it more difficult to interchange the addon. I updated and i added some info and instructions in the readme. Hope that i will manage to solve that issue.
