Hello,

So I changed the makefile from CC=CC to CC=g++. I also put changed
xairy.out > xairy.reslt && \
to
./xairy.out > xairy.reslt && \

as was suggested for another users errors
Now I get the following error:

g++ -I/usr/local/src/recipes_cpp/utils -I. -o xairy.out xairy.o airy.o bessik.o bessjy.o beschb.o chebev.o -lm
./xairy.out > xairy.reslt && \
/usr/local/src/recipes_cpp/utils/nrdiff.pl xairy.reslt /usr/local/src/recipes_cpp/demo/answers
/bin/sh: /usr/local/src/recipes_cpp/utils/nrdiff.pl: /usr/local/bin/perl: bad interpreter: No such file or directory
make: *** [xairy.reslt] Error 126

And the files produced are:

airy.o bessik.o chebev.o fncval.dat makefile~ matrx1.dat matrx3.dat table1.dat tarray.dat xairy.o xairy.reslt
beschb.o bessjy.o dates1.dat makefile make.log matrx2.dat spctrl.dat table2.dat text.dat xairy.out


Does anyone have any ideas on how I should proceed to get these code running. Thanks. porter

Hi Porter,

The utility nrdiff.pl checks the output of the test run against the "correct" answers. It assumes that your perl program is in
/usr/local/bin/perl
Check this by typing
which perl
at a command prompt. If you get, for example,
/usr/bin/perl
then change the first line of nrdiff.pl to match this.

Saul,
That did the trick. Thank You. porter
