These are the directions I used :

Building IMP from source is straightforward if the prerequisites are already installed. We recommend you get IMP from git by git clone git://github.com/salilab/imp.git To build, create a directory to build IMP in (it is good practice not to build in the source directory and do)

cmake ../imp -DCMAKE_BUILD_TYPE=Release
make -j 4

The only change I did was to disable Doxygen.

I did the git clone about 12 hours ago.

The build runs OK until it fails on one of the swig creation phases :

[ 70%] Built target _IMP_symmetry
[ 70%] Built target imp_symmetry_python

When trying to execute the same command myself (the swig command that fails with error code 1) I get :

bojemoi@linux:~/university/imp-release$ swig -castmode -interface _IMP_rmf -DPySwigIterator=IMP_RMF_PySwigIterator -DSwigPyIterator=IMP_RMF_SwigPyIterator -python -c++ -naturalvar -fvirtual -Wextra -I../../include -I../../swig -oh wrap.h-in -o wrap.cpp-in -I/home/bojemoi/university/imp-release/include -I/usr/include /home/bojemoi/university/imp-release/swig/IMP_rmf.i

/home/bojemoi/university/imp-release/swig/IMP_rmf.impl.i:1: Error: Unable to find 'RMF.i'

Many other modules that do not relate to RMF.i build correctly and I can import them from python , but I happen to need multfit that DOES require RMF...

I tried to search for RMF.i in my release directory :

bojemoi@linux:~/university/imp-release$ find | grep RMF
./include/IMP/rmf/RMFWriter.h
./data/build_info/RMF

bojemoi@linux:~/university/imp-release$ cat data/build_info/RMF
ok=True
includepath=""
swigpath=""
libpath=""

Swig version is 2.0.4 by the way.

Thank you!
