From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0 Description of problem: The rpm includes the following: /usr/lib/liblapack.so.3 /usr/lib/liblapack.so.3.0 /usr/lib/liblapack.so.3.0.3 but not /usr/lib/liblapack.a /usr/lib/liblapack.so which are needed for linking code that calls lapack routines. Version-Release number of selected component (if applicable): lapack-3.0-30.fc4 How reproducible: Always Steps to Reproduce: 1. Write some code that calls the lapack routines, e.g. foo.f: program foo call dgetrf end 2. Compile it and link, e.g. g77 -o foo foo.f -llapack 3. Actual Results: Linker bombs out saying "ld: cannot find -llapack". No executable is produced. Expected Results: Link step should produce an executable foo. Additional info: Workaround for the lack of the .so library is simple: manually make a symlink to .so.3. The lack of .a library is not easily worked around, but it is needed only if statically linking so it is not a problem unless you want to send binaries to others who don't have lapack installed.
Installing the accompanying -devel subpackages in order to build software has been required for at least 7 years or so. Install the lapack-devel package.
To be fair, lapack has been one of the odd packages which has not historically been doing this. I corrected it recently, because, well, it needed to be done, but I expected to see a bug-report like this eventually. Sorry for any temporary pain this may have caused you. By installing lapack-devel, your issues should go away.
Tom, you are quite right. I had assumed lapack was for development because it had always worked that way.
