Re: [Lapackpp-devel] lapack++ compilation failure on linux

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

Dear Vincent,

I have never heard of the "insure" compiler, so I have to say that 
lapackpp hasn't been tested with that before.

The error you are seeing is caused because I some C extensions which are 
specific to the GNU gcc have been used when dealing with complex 
numbers. I think you can easily solve this issue by changing the line 50 
in the file include/lacomplex.h.in into

#define LAPACK_USE_GCC3 0

Calling "make" again (which will create the file include/lacomplex.h 
from the file you just edited) should then fix your error.

(More specifically, the file "include/lacomplex" used the __complex__ 
attribute of the gcc, which obviously your insure compiler doesn't know. 
Fortunately, this particular section will be disabled if the macro 
LAPACK_USE_GCC3 is defined to zero.)
