Apologies in advance: This is a C question, but I know a lot of you
write your own DLMs for IDL and I'm completely stumped. I have a DLM
with this statement, patterned after Ronn Kling's book, near the middle
of the code:
w = (float *) IDL_MakeTempArray( (int) IDL_TYP_FLOAT, ndim_w, dim_w,
IDL_ARR_INI_ZERO, &ivWptr );
The DLM compiles and runs perfectly on the win32 platform. When I try to
compile the exact same code to the x64 platform, all of the statements
which follow the above one are riddled with crazy syntax errors. All
those preceding it are accepted. I'm using Visual C++ 2010 Express with
the Windows SDK Version 7.1.
Any help for a complete C novice?
Thanks
Mort

That sounds _very_ likely. Typical beginner's blooper. Thanks Karl.

Sort of looks like you are declaring a variable, s, in the middle of a
code block. To enable this to compile, you have to compile the C code
in C++ mode, or set a compiler option to allow this usage. Or, you
can put
culaStatus s;
up above the comment line:
// IDL output arrays
and then just say:
s = culaInitialize();
Somehow you were compiling the code with different options for 32-bit
and 64-bit.
Either fix the code to make it legal C (I know some newer C standards
allow this) or set your project file up to use the same compiler
options for 32-bit and 64-bit. My guess is that the x64 Debug config
does not have the "compile as C++" option set.

Hi Ronn,
Here's the whole thing (not very long):
void IDL_CDECL cuda_svd(int argc, IDL_VPTR argv[])
{
// output array pointers
float * w, * u, * vt;
// get the input matrix
float * a = (float *) argv[0]->value.arr->data;
// get its dimensions
int ndim_a = (int) argv[0]->value.arr->n_dim;
IDL_LONG64 * dim_a = argv[0]->value.arr->dim;
int m = (int) dim_a[0];
int n = (int) dim_a[1];
// IDL output arrays
IDL_VPTR ivWptr, ivUptr, ivVTptr;
int ndim_w = 1;
IDL_LONG64 dim_w[] = {min(m,n)};
IDL_LONG64 dim_u[] = {m,min(m,n)};
IDL_LONG64 dim_v[] = {min(m,n),n};
w = (float *) IDL_MakeTempArray( (int) IDL_TYP_FLOAT, ndim_w, dim_w,
IDL_ARR_INI_ZERO, &ivWptr );
u = (float *) IDL_MakeTempArray( (int) IDL_TYP_FLOAT, ndim_a,
dim_u, IDL_ARR_INI_ZERO, &ivUptr );
vt= (float *) IDL_MakeTempArray( (int) IDL_TYP_FLOAT, ndim_a, dim_v,
IDL_ARR_INI_ZERO, &ivVTptr);
// CULA general matrix single precision SVD with host pointers
culaStatus s = culaInitialize();
if(s == culaNoError)
{
s = culaSgesvd('S','S',m,n,a,m,w,u,m,vt,min(m,n));
culaShutdown();
}
// return results to IDL (all zeroes if CULA failed to initialize)
IDL_VarCopy(ivWptr,argv[1]);
IDL_VarCopy(ivVTptr,argv[2]);
IDL_VarCopy(ivUptr,argv[3]);
}
Here is what the compiler puts out:
1>------ Build started: Project: cuda_svd, Configuration: Debug x64 ------
1> cuda_svd.c
1>D:\Idl\projects\development\svd\cuda_svd.c(50): error C2275:

========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========
I discovered if I move the statement
culaStatus s = culaInitialize();
upwards, preceding the comment line
// IDL output arrays
the damn thing builds (and runs correctly under IDL)! Way over my head,
I'm afraid.
Thanks,
Mort

Hi Mort,
Can you show me how you have declared the variables in the call?
