[Qucs-help] Strange buildproblem Qucs 14

[<chl...@gm...>]

Hello,

i already sucessfully built Qucs 13 on my system. Trying to build
release 14 on the same system i get following error:

if g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../src/math -I../src/components

-MP -MF ".deps/check_touchstone.Tpo"
hstone.o check_touchstone.cpp; \
then mv -f ".deps/check_touchstone.Tpo" ".deps/check_touchstone.Po";
else rm -f ".deps/check_touchstone.Tpo"; exit 1; fi

Well i do not understand why with qucs 13 there were no compiler errors.
However a cast to (double)() in touchstone
solves the compiler problem (and the make runns through), but i'am
unfortunately not so deep inside the qucs code to judge wheather this is
an old libc problem of my system or if it is a serious type conversion
problem within touchstone. 

Another question/remark concerning the same line: Wouldn't it be better
to change the division by /2 into /2.0 in touchstone_options.ports =
(int) sqrt ((size - 1) / 2) ? 
 

Best regards Markus
