[Kaldi-users] Fail to compile test code in trunk with intel compiler icc/icpc -O3

[Mailing l. u. f. U. C. a. U. <kal...@li...>]

hi,

I'm trying to compile kaldi with intel compiler and option '-O3'.
I got an Error when compiling the test code in dir 'trunk/src/matrix' as
follows.
This error does not happen when compile with 'gcc' or 'icpc -O2'.

It seems 'icpc -O3' optimized out the interface of  the instantiated
template function
void SpMatrix<Real>::Qr(MatrixBase<Real> *Q);

Maybe SpMatrix::Qr()have to be explicitly instantiated in qr.cc in this
case.

Best,
Shiyin
