I’m sorry for be such a pain, but I can’t compile mitsuba yet.

I have tried you told me (I modified the config.py as well as you said) but nothing.

Also I created a softlink to libGLEW.so.1.5.7 called libGLEWmx.so

In both times I get this error:

g++ -o src/utils/createvol src/utils/createvol.o -Lsrc/libcore -Lsrc/librender -Lsrc/libhw -ldl -lm -lpthread -lgomp -lboost_system -lboost_filesystem -lmitsuba-core -lmitsuba-render -lmitsuba-hw

Any help?

An alternative is to edit the config.py file and specify a different library name (e.g. remove the “mx” on line 16).

Good luck,
Wenzel

The things I have done is uninstall glew (make uninstall-make clean) and make it again like that:
make GLEW_MX=1
make install

but nothing :-(

I am trying to compile mitsuba on my computer -Slackware64 13.1- and I get the same error:

Actually, I am installing the libraries that Scons needs reading the error messages.

First, Scons stopped because it needs xercesc, and I installed it. (no problem here)

Then, Scons stopped because the error related with lGLEWmx I put above.
I installed Glew from http://glew.sourceforge.net/advanced.html
but I got an error. Then, I see that there are a similar problem and I have uninstalled Glew, and I have reinstalled again with the parametres into …glewmx/PKGBUILD, but notihng :-(

P.S. I have duplicated the post because I submitted the coment instead press “Preview”. I’m sorry

since you’re on Slackware, you will need to build this library yourself. It is basically GLEW, but compiled with -D GLEW_MX. You can take a look at the GLEW documentation for information on how to build with this flag.

Best,
Wenzel

Blender inserts a weird “UNKNOWN” tag at the top. You need to get rid of this.

Can you send a screenshot and your copy of mitsuba_*.log (should be in the directory where you started the program)

the COLLADA problem is due to a bug in Blender (see https://projects.blender.org/tracker/?func=detail&atid=498&aid=24145&group_id=9), which will be gone in the next version. You can work around it temporarily by editing the DAE file and removing the text “” at the top.

Regarding the OBJ import problems: I’ve been chasing this bug! Can you do me a huge favor and send the file which you can’t import to my email address? The address is my first name @cs.cornell.edu.

Thanks,
Wenzel

yes glew was installed

It appears that Mitsuba uses (plain) “glew”, instead of “glewmx”. Do you perhaps have glew installed? The “ldd” tool may be useful to analyze which libraries are being used (run “ldd mtsgui”). You may need to adjust the files in /usr/lib manually if you are using conflicting packages.

I’ve tried Ubuntu before Arch… I agree with your view you are right.

But I sensed that Ubuntu was “obscure” in terms of learning Linux. It has the same flaws I don’t like in Windows, it makes everything for you and doesn’t let you understand the process… Now i’m trying to compile the package from source, in Ubuntu I’d be installing the .deb just by clicking without any question… Maybe later I’ll come back to automated distributions for productivity’s sake, but now I prefer to learn some of theses technical basis.

The construction is finished, I’ve set the path with . setpath.sh, the program is working but for the gui it asks me for :

./mtsgui: symbol lookup error: /home/omar/Applications/mitsuba/src/libhw/libmitsuba-hw.so: undefined symbol: glewContextInit

Just a tip in case it is useful: If you’re new to Linux and having difficulties with Archlinux, I’d recommend using another distribution such as Ubuntu or Fedora. From playing around a bit with Archlinux today, my impression is that it assumes quite a bit of technical Linux experience on the part of the user.

I’ve simply done the makepkg -s within the directory of each one, then I tried the make, then make install commands in te src directory. It gave me errors too, maybe i’m doing something bad

Thanks in advance

are you sure you installed the packages after building them? (just building is not enough).

In theory, the build file (https://www.mitsuba-renderer.org/releases/contrib/archlinux/glewmx/PKGBUILD) should make a symlink to this library — it works on my machine.

Best,
Wenzel
