Hi, I have on my opensuse 10.2 system a libblas.so.3 with the following problem: bartosch@gunter> ldd -r /usr/lib64/libblas.so.3 undefined symbol: _gfortran_st_write_done (/usr/lib64/libblas.so.3) undefined symbol: _gfortran_transfer_integer (/usr/lib64/libblas.so.3) undefined symbol: cabs (/usr/lib64/libblas.so.3) undefined symbol: _gfortran_stop_numeric (/usr/lib64/libblas.so.3) undefined symbol: _gfortran_st_write (/usr/lib64/libblas.so.3) undefined symbol: cabsf (/usr/lib64/libblas.so.3) undefined symbol: _gfortran_transfer_character (/usr/lib64/libblas.so.3) libc.so.6 => /lib64/libc.so.6 (0x0002b31ac563000) /lib64/ld-linux-x86-64.so.2 (0x0000555555554000) The library does not have libgfortran and libm as its dependencies. How can I change the libblas.so.3 such that libgfortran and libm appear as its dependencies? Christoph
