External Email - Use Caution Hi there,
Thank you for directing me to the CMake fswiki. I was able to install the third party packages and execute the command `cmake . -DFS_PACKAGES_DIR="path/to/pkgs"`. However, when I run `make -j4` (after adjusting a few bash files in various libraries to find (#include) other libraries) I am met with numerous similarly-worded link error lines under the step "Linking Fortran executable t4imgs_4dfp" with the general schema: /usr/bin/ld: path/to/fortran-related/filename: relocation R_X86_64_32 against `some.variable.or.file.name` can not be used when making a PIE object; recompile with -fPIC where path/to/fortran-related/filename is either CMakeFiles/t4imgs_4dfp.dir/some-file.c.o or /usr/lib/gcc/x86_64-linux-gnu/4.8/libgfortran.a(some-function.o) I tried finding a solution online and found the suggestion to add a global -fPIC flag via export CXXFLAGS="$CXXFLAGS -fPIC" (https://stackoverflow.com/questions/13812185/how-to-recompile-with-fpic). I tried this by starting completely over with a new clone of the freesurfer repo and calling cmake . -DFS_PACKAGES_DIR="path/to/pkgs" and the make still failed at the same point. Other suggestions (e.g., to add --enable-shared at ./configure(in that same thread linked above)) suggest adding arguments when configuring, but since this is all part of the make process I'm not sure whether that's possible. Any advice? I did not find any similar issues in the archive. Thank you very much, Christian McDaniel ________________________________ From: fsbuild <fsbu...@contbay.com> Sent: Wednesday, October 31, 2018 2:29:59 AM To: freesurfer@nmr.mgh.harvard.edu Cc: Christian Lee Mcdaniel Subject: Re: [Freesurfer] Third party dependencies directory not found when building from source ​Hello Christian, Allow me to suggest that you try following the instructions for the Fresrufer cmake build located here, http://freesurfer.net/fswiki/CMake Besides the option to build the 3rd party packages with build_packages.py script, you can also download an archive of the prebuilt packages from http://surfer.nmr.mgh.harvard.edu/pub/data/fspackages/prebuilt/ Another option would be to install the equivalent of the CentOS 7 packages on the Ubuntu system you are using, i.e., you may need to install at least cmake, so you will likely need sudo/admin privileges.

I have followed the instructions on the freesurfer_linux_developers<http://freesurfer.net/fswiki/freesurfer_linux_developers_page> wiki, and have successfully gotten through steps 1 and 2. However, when trying to install the third party dependencies at step 3 via wget ftp://surfer.nmr.mgh.harvard.edu/pub/dist/fs_supportlibs/prebuilt/centos6_x86_64/centos6-x86_64-packages.tar.gz, I get the following response:
