LAPACKE_dtpqrt cannot be found

[T__Mineno]

Hello.
I'm writing some of code using LAPACKE_dtpqrt function. 
In MKL 11.0.1.117, however, Intel c compiler could not link this function and reported error message "undefined reference to `LAPACKE_dtpqrt'".

From release note and reference manual, I should be able to use this function.

http://software.intel.com/sites/products/documentation/doclib/mkl_sa/11/mklman/GUID-4E76B45F-A4E9-42...

My code can be compiled by using netlib's LAPACKE. So, what's wrong?

Hi tmineno, I can see this routine in mkl_lapacke.h header file: lapack_int LAPACKE_dtpqrt( int matrix_order, lapack_int m, lapack_int n, lapack_int l, lapack_int nb, double* a, lapack_int lda, double* b, lapack_int ldb, double* t, lapack_int ldt ); therefore, pls check if your test contains include "mkl_lapacke.h" or pls check how do you link the application - see mkl linker adviser from here :http://software.intel.com/sites/products/mkl/ --Gennady

Thank you your comment, Gennady. I have tried include mkl_lapacke.h explicitly, but the problem would not be still solved. Here, I show a little test code below. test.c [cpp] #include "mkl_lapacke.h" int main(){ double A[9] = { 1,2,3, 0,1,2, 0,0,1 }; double B[9] = { 1,2,3, 4,5,6, 7,8,9 }; double T[9] = {0}; LAPACKE_dtpqrt(LAPACK_ROW_MAJOR, 3, 3, 0, 3, A, 3, B, 3, T, 3); return 0; } [/cpp] command line [bash]icc -openmp test5.c -o test5 -lmkl_intel_lp64 -lmkl_intel_thread -lmkl_core -lpthread -lm[/bash] error message /tmp/iccNwvErC.o: In function `main': test.c:(.text+0x126): undefined reference to `LAPACKE_dtpqrt' However, gcc with netlib's LAPACK(E) succeeded in compilation [bash]gcc -o test test.c -llapacke -llapack[/bash]

yes, that's the problem - i don't see this function in mkl's binaries too. the problem is escalated. I will let you know when the problem would be resolved.
