Re: [Lapackpp-devel] linker error with lapackpp-2.1.0

[Christian S. <sti...@tu...>]

Hi,

good to hear that other people are using our software :-)

I didn't see any of these linker errors so far, so your environment is 
probably different than mine. What compiler is this? And how do you 
include your Lapack++ headers?

I'd guess you are using
#include <lapack++.h>
or something comparable to this, and yes, there were some changes in the 
inclusion order inside that header file. This might result in the fact 
that the _LA_GEN_MAT_COMPLEX_H_ macro is now defined, which will make 
this function visible, whereas in previous versions it might have been 
invisible.

I don't understand why the function definitions have been written in the 
header file in the first place. I'd have expected them to be written in 
the cpp file, but that's how they came from lapack++ version 1.1. 
Nevertheless the linker error should also disappear if you make the 
function declaration "inline", i.e. you write

inline LaGenMatComplex& LaRandUniform(LaGenMatComplex &A, double low, 
double high)
{ // ....

Does this fix the problem, too? If it does, I'll quickly make a new 
release with this bugfix.
