linux - /usr/bin/ld: cannot find -llapack

Question

I am seeking help for installation in ubuntu 14.04. I am installing a package in my pc. They have their makefiles. I have to run make.

When I did I found error like.....

gfortran -O2 -fopenmp -msse2 -o nmbnd.run p_nmbnd.o i_main.o m_getwsr.o ../IOLIB/*.o ../ATOM/*.o ../BNDASA/*.o ../EXTENS/*.o ../FINDES/*.o ../LATTICE/*.o ../SAMPLE/*.o ../TETRA/*.o ../IOCTRL/*.o ../LMIO/*.o ../MAINA/*.o ../NMTO/*.o ../SYM/*.o ../TBSTR/*.o ../CHAPOT/*.o  -L/usr/share/doc/liblapack -llapack -L/usr/share/doc/libblas -lblas 
/usr/bin/ld: cannot find -llapack
/usr/bin/ld: cannot find -lblas
collect2: error: ld returned 1 exit status
make[2]: *** [nmbnd.run] Error 1
make[2]: Leaving directory `/home/santuphys/NMTO-47.ZB.28/06.gfort/MAIN'
make[1]: *** [cleanmake] Error 2
make[1]: Leaving directory `/home/santuphys/NMTO-47.ZB.28/06.gfort/MAIN'
make: *** [ooo.dep] Error 2

I tried all the other similar questions in this forum about link, but I could not resolve it. I specified the path to Lapack and Lblas in my pc also writing...

LAPACK_LIB=   -L/usr/lib/ -llapack  -lblas

It did not work. Please help me with this issue.

Thanks in advance.

On Ubuntu 14.04 make sure you have the packages

• liblapack-dev
• liblapack3
• libopenblas-base
• libopenblas-dev

installed. After that, "-L/usr/lib -llapack -lblas" should work. Also note that, as already mentioned in another answer, in the output you showed, you have "-L/usr/share/doc/liblacpack -L/usr/share/doc/libblas", which is certainly not what you want.
