C/C++ Link error when LAPACK and BLAS is used

[danesh_d]

I have used few BLAS and LAPACK functions in my code on OpenSUSE (64-bit). The code is compiled successfully but when the linking is in process, unresolved error message is shows. I have tried to add new compiler switches but the erorr is not solved. I also ran the environtment script from tools folder at MKL directory. The output I get is:

and many other unresolved error. I can successfully compile example files. but my own code can not be compiled. Does anybody know what this happens?

Thanks in advance,

The errorsare ipo (inter procedural optimization) faults, so it is hardly connected with MKL. Could you try to build without -ipo option?

Well I did and now I get these errors:

FieldCalculator.cpp:(.gnu.linkonce.t._ZNSt6vectorIS_I13complexVectorSaIS0_EESaIS2_EE9push_backERKS2_[.gnu.linkonce.t._ZNSt6vectorIS_I13complexVectorSaIS0_EESaIS2_EE9push_backERKS2_]+0x1fe): undefined reference to `__cxa_end_catch'

the interesting thing is that I have not used any of MKL libraries in "FieldCalculator.cpp" so I don't know what linker is complaining about.

Thanks,

It looks liike you are trying to compile and link C++ code, but are using the icc C compiler. The C++ compiler is icpc, which will be capable of C++, and, to a limited extent, C.

Yes you are right, I used "icpc" instead but I still got errors about unresolved reference to MKL functions that I used. So I copied path to libraries from examples (LIB=...) and it worked finally. Thanks for your hints.
