[Octopus-devel] Compiler warnings

[Tobias Burnus]

Hi all,

I just want to mention the following compile warnings (against SVN version):


**********liboct_parser********
string_f.c(64): warning #186: pointless comparison of unsigned integer
with zero
        for(l--; l>=0; l--)                 /* find length of fortran
string */

********* liboct **********
write_iter.c(146): warning #181: argument is incompatible with
corresponding format string conversion
        sprintf(w->buf+w->pos, "%8i%20.12e", w->iter, w->iter*w->dt);
w->pos+=8+20;
                                                ^

Per ISO C99 standard size_t is unsigned (with system-defined length). On
my systems it is also long ("%lu").

********* libxc *********

mgga_c_tpss.c(150): warning #592: variable "a" is used before its value
is set
        double a = gzeta[i]/(sqrt(gzeta2)*a);
                                          ^

You are probably less interesed in external_libs. For completeness (with
ifort -gen-interfaces - this generates a *_mod.mod and *_mod.f90 file to
do interface checks):
**** expokit ***
fortcom: Error: expokit.f90, line 1512: The type of the actual argument
differs from the type of the dummy argument.   [WSP]
         call DNCHBV(mx,sgn*t_step,wsp(ih),mh,wsp(iexph),wsp(ifree+mx))
---------------------------------------------------------^

This seems to be a problem of double-precision vs. complex. I don't know
whether this is a real problem or not.
