Hi Rick,<br>
<br>
What would the appropriate definition of M_PI be? <br>
<br>
Also note that I'm compiling with V4.9 of gcc and ifort. The same
file must have compiled ok when I built with gcc/gfortran (both
4.9). <br>

ps. And I have compiled ncarg successfully on a mac with ifort/gcc
a few years ago with maybe 10.6.<div><div class="h5"><br>

<div>Hi Dave,<br>
<br>
</div>
I'm not totally sure about this one, but it appears M_PI
*may* be a GNU-ism -- a non-standard constant specific to
the gcc compiler. I'll investigate this further, but if
that's the case, we clearly should not rely on such a
compiler-specific idiom. In the mean time, you could patch
your copy of cro.c with the appropriate definition in order
to move forward. <br>
<br>

You say there are many errors -- are they beyond just this
particular symbol being undefined?<br>

Hi,<br>
<br>
I am having troubles building NCAR Graphics (6.2.0) on
OS 10.9 with<br>
ifort (V13.0.2).<br>
<br>
First of all, with the same machine I have successfully
compiled it with<br>
gfortran (both library versions are needed by the
researcher).<br>
<br>
The first error (there are many) is:<br>
<br>
gcc-mp-4.9 -ansi -m64 -fopenmp -lsz -O
-I../../../.././include<br>
-I/opt/intel/composer_xe_2011_sp1.10.328/compiler/include<br>

-I/opt/X11/include/freetype2<br>
-I/opt/local/hdf4/ifort/include
-I/opt/local/szip/ifort/include<br>
-DDarwin -DCTXT -DX11 -DPS -DPDF -DPIX -DSYSV
-D_POSIX_SOURCE<br>
-D_XOPEN_SOURCE -DByteSwapped -D__UNIXOS2__
-DNeedFuncProto -c -o<br>
cro.o cro.c<br>
cro.c: In function 'cro_Polymarker':<br>
cro.c:1451:71: error: 'M_PI' undeclared (first use in
this function)<br>
cairo_arc(context, xc, yc, mscale *
marker_size, 0., 2. *<br>
M_PI);<br>
^<br>
cro.c:1451:71: note: each undeclared identifier is
reported only once<br>
for each function it appears in<br>
make[5]: *** [cro.o] Error 1<br>
<br>
The cro.c file is this one:
./ncarg2d/src/libncarg_gks/cdrivers/cro.c<br>
<br>
Any idea where MP_I is supposed to be defined?<br>
