[Bug-gsl] make check error with icc 11.0 for gsl 1.14 gsl: lu.c:147: ERROR: matrix is singular

[Kirill Igumenshchev]

i'd like to compile gsl with icc since it's a lot faster.

the gsl compiles if i follow
http://dererumnatura.us/archives/2009/03/compiling-gsl-1.html.
however, in my code I mostly solve ODEs and would like to vectorize
ode routines to get a better performance. if i don't follow the last
line from the link which says to put "-no-vec" into ode-intval's make
file, i get 1 error:

any thoughts how i can get the vectorization to work?

as another way to approach the problem, is it possible to just use the
ode routines without compiling the library? I mean to put the gsl's .h
files in the same directory as my program and comile the needed gsl .h
files together with the program.

thank you,
