Try rm -r CMake* ubuntu-gnu_g/CMake* # reconfigure if ubuntu-gnu_g/conf/PETScConfig.cmake is missing # otherwise you can just run config/cmakeboot.py (faster) make -C ubuntu-gnu_g

Jed and Satish, Thanks for your responses. However, that is the first thing that I tried: rmills@ubuntu:~/proj/petsc-dev$ make -C ubuntu-gnu_g/ make: Entering directory `/home/rmills/proj/petsc-dev/ubuntu-gnu_g' make: *** No targets specified and no makefile found. Stop. make: Leaving directory `/home/rmills/proj/petsc-dev/ubuntu-gnu_g' Then I assumed that the instructions meant to say 'cmake', not 'make'. What is supposed to generate the makefile that gets used? --Richard On 2/2/2011 11:03 AM, Jed Brown wrote: > On Wed, Feb 2, 2011 at 12:55, Satish Balay <balay(a)mcs.anl.gov > <mailto:[email protected]>> wrote: > > > rmills@ubuntu:~/proj/petsc-dev/ubuntu-gnu_g$ cmake .. > > You haeve to use 'make' or 'make -j 4' here - not 'cmake' > > I just do: [from petsc-dev] > make -C ubuntu-gnu_g -j 4 > > > Same here.

Trying to get the CMake instructions to work, unsuccessfully

Hi Folks, I am attempting to use the CMake stuff that Jed put in place to build PETSc. I'm following the instructions currently found at http://www.mcs.anl.gov/petsc/petsc-2/developers/index.html: > The main reasons for using CMake are parallel builds, dependency analysis, > and IDE integration. The following instructions assume that you have CMake > version 2.6 or later installed. > > 1.

Run make in the build directory ($PETSC_DIR/$PETSC_ARCH), the value of > the environment variables is not important. > Do these need updating? Or am I just doing something stupid? I've run configure with '--with-cmake' specified appropriately, and a top-level CMakeLists.txt file gets created. But when I try to run cmake with $PETSC_DIR/$PETSC_ARCH as my build directory, I get ----- rmills@ubuntu:~/proj/petsc-dev/ubuntu-gnu_g$ cmake .. CMake Error at CMakeLists.txt:4 (include): include could not find load file: /home/rmills/proj/petsc-dev/conf/PETScConfig.cmake -- Configuring incomplete, errors occurred! ----- Line 4 of the CMakeLists.txt file attempts include (${PETSc_BINARY_DIR}/conf/PETScConfig.cmake) It looks like PETSc_BINARY_DIR should be $PETSC_DIR/$PETSC_ARCH, but just $PETSC_DIR is being used. How is this supposed to be set? I don't know CMake very well, so my apologies if this is a dumb question.
