Have since updated to lapack-3.4.1-1 when it came out. Fewer undefined references when linking to the shared liblapacke, but still some
{cdsz}lagge_
{cz}laghe_
{cdsz}lagsy
{cdsz}latms
This also happens when using the upstream distribution.
It turns out that these functions are not in the lapack/SRC directory but in the TESTING directory and are not included in liblapack.
They should probably not be included in liblapacke either. A simple change to lapacke/src/Makefile would solve this

Created attachment 617101 [details] the source program Description of problem: Linking a simple c program to lapacke works when using the static liblapacke.a but when using the shared liblapacke.so, it failes with undefined references Version-Release number of selected component (if applicable): lapack-3.4.0-2.fc17 How reproducible: always Steps to Reproduce: 1.a .c program with a call to LAPACKE_dgels 2.link with default shared libraries cc dgels.o -llapacke -llapack -lblas -lgfortran -lm 3. Actual results: /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `zposvxx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `clagge_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `clatms_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `chesvxx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `cposvxx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `cgesvxx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `ssyrfsx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `csyrfsx_' /usr/lib/gcc/i686-redhat-linux/4.7.0/../../../liblapacke.so: undefined reference to `dlagsy_' .... many more, these references are mostly irrelevant to the program Expected results: successful linking Additional info: installing lapack-static and compiling with cc dgels.c -Wl,-Bstatic -llapacke -Wl,-Bdynamic -llapack -lblas -lgfortran -lm is successful
