These are the steps I use to build ogre, which I think is pulling down 1.10.

$ hg clone https://bitbucket.org/sinbad/ogre
$ cd ogre
$ mkdir build
$ cd build
$ cmake .. -DCMAKE_INSTALL_PREFIX=/opt/ogre
$ make -j8
$ sudo make install

However, after executing make, I get the following error ...

Code: Select all

Any ideas where I'm going wrong?

this should'nt happen...if you dont have swig and python installed then the python binding module is supposed to be ignored...
https://bitbucket.org/sinbad/ogre/src/3 ... ew-default

i remember from the days of using gcc that using -j option always caused the build process to break at some point( do you realy have 8 cores?

) but if i typed make again then the build would continue( IIRC make without the -j option )
so i think maybe you can just ignore it and try to continue your build with just make, if it doesn't work call us again...
but if you want fixed ogre with cool python bindings just install python and swig

btw..fastest safest way to build ogre is enabling "unity build" option in cmake( why not use cmake-gui? )
and using make without -j( unity builds are single threaded anyway )

try with a

Code: Select all

hg update

if you just do a clone, you will not have the last update

are you building the Python component on purpose? And if so which version of SWIG do you have? Probably this whole block can just be deleted:
