9. Common Installation and Execution Problems¶
Do you have a problem that is not documented below? No matter how trivial the problem might be, please raise an issue.
9.1. (The program hangs)¶
This is probably because a Bifrost pipeline was started with an infinite timeout, and some blocks are not ending themselves. Quit the program (by ctrl-\), and make sure every block in your pipeline is reading/writing to its rings as it should.
9.2. OSError: Can’t find library with name libbifrost.so¶
This means that the bifrost Python wrapper can’t find your Bifrost installation. Whatever library folders it searches for Bifrost, you do not have the libbifrost.so file there. To fix this, type
echo $LD_LIBRARY_PATH
at your command line. If none of these folders contain the Bifrost installation (which you may have specified with configure), you have found the problem. Perform
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/my/bifrost/installation,
where /my/bifrost/installation is the folder where you installed the
Bifrost “lib” (this location will also be reported as part of make install).
This should add Bifrost to the wrapper’s search path.
