Dan,

It works for me; as an example:

multi.c
-------

#include <stdio.h>
#include "idl_export.h"

void do_work(float *a)
{
printf("%f\n",a[3+5*10+7*10*20+9*10*20*30]);
}

IDL_VPTR multi(int argc, IDL_VPTR argv[])
{
do_work((float *) argv[0]);
}

multi.pro
---------

pro multi
a=fltarr(10,20,30,40)

a[3,5,7,9]=3.14

junk=call_external('multi.so','multi',a,/unload)
end

Compile
-------

gcc -I /usr/local/rsi/idl/external/include -shared multi.c -o multi.so

does the above work for you? Can you post an example of code which fails?

Thanks,

Allan
