I am not sure whether someone has already responded to this compilation
error. Sorry for duplicated posting if there was an answer.
The problem is the version of gcc coming with OSX is too old. I had the
same error using gcc-4.2. The solution is simply to use a newer gcc such
as "./configure --prefix=/opt/sac101.4 CC=/sw/bin/gcc-4" with gcc
version 4.6.3 (GCC).

Attempting to compile sac-101.5c using gcc version

I get a series of compiler errors stemming from the following code in
hdr.h
I want to compile this so I can run SAC under the debugger to track
down problems.
gcc -DHAVE_CONFIG_H -I. -I../inc -I../inc
-I../libedit/include -DDOINITS -c ./dff/hdrfld.c -o dff/hdrfld_io.o
In file included from ./dff/hdrfld.c:12:
../inc/hdr.h:287: error: initializer element is not constant
../inc/hdr.h:288: error: initializer element is not constant
../inc/hdr.h:289: error: initializer element is not constant
The offending lines follow the ifdef below.
#ifdef DOINITS
float *const a = (float*)((char*)cmhdr.fhdr + 32);
float *const arrivl = (float*)((char*)cmhdr.fhdr + 32);
float *const az = (float*)((char*)cmhdr.fhdr + 204);
And many more follow.
Is there an easy way to fix this?
I am neither a skilled C coder nor Mac user.
