Ubuntu system, GSL Library link problem-undefined reference to ' cblas_xxx '

The following error message appears when the program is being debugged under Ubuntu system today:

[Ten%]linking CXX executable. /test_coco/usr/local/lib/libgsl.so:undefined reference to ' CBLAS_ZTRSV'/usr/local/lib/libgsl.so:undefined reference to ' Cblas_scasum'/usr/local/lib/libgsl.so:undefined reference to ' Cblas_izamax'/usr/local/lib/libgsl.so:undefined reference to ' Cblas_dnrm2'/usr/local/lib/libgsl.so:undefined reference to ' Cblas_zdotc_sub'Collect2:error:ld returned 1 exit status Make[2]: * * * [Test_coco] Error1 Make[1]: * * * [Src/cmakefiles/test_coco.dir/ALL] Error2 Make: * * * [ALL] Error2

As can be seen, the previous compilation is not a problem, in the last link stage error, according to the hint, LIBGSL library link related files when there is a problem. The LIBGSL library relies on related files in the Clbas library. So after the link GLS also need to add to the Gslcblas link, problem solving!
