libpthread.so.0: error adding symbols: DSO missing from command line

Question

When I\'m compiling openvswitch-1.5.0, I\'ve encountered the following compile error:

 gcc -Wstrict-prototypes -Wall -Wno-sign-compare -Wpointer-arith
     -         


        

Answer 1

I found I had the same error. I was compiling a code with both lapack and blas. When I switched the order that the two libraries were called the error went away.

"LAPACK_LIB = -llapack -lblas" worked where "LAPACK_LIB = -lblas -llapack" gave the error described above.
