similar to: Calling FORTRAN function from R issue?

Linux users are used to all compilers using the same linkage conventions (those of pcc) whereas users of other platforms are used to the idea that code from different compilers cannot in general be mixed. This is no longer true for gfortran on AMD64. Given a double complex function like double complex function zdotc(n,zx,incx,zy,incy) gfortran returns the result in a 128-bit XMM SSE

I'm trying to generate an R interface for a library that's commonly used and I'm currently writing wrapper functions for file i/o and return an object (list?) that contains the elements of the C structure. For example, reading a file that contains: struct CONFIG_RECORD { char coeffs_filename[256]; char species_filename[256]; unsigned long

Hi all All my forms should look the same, so I think always putting the right div etc. tags around them is a violation of the DRY principle. Until now my forms look like that: <div class="text_field"> <label for="news_item_subject">Subject:</label> <%= text_field "news_item", "subject" %> </div> Now I want the default

I've been working on a shared library that will be called from R. The functions pass several vectors in and out (residuals, parameters, etc) and I would like to be able to return a list of objects. I'm familiar with return single objects (vectors, etc) from a C function, but need a little help for returning a list of objects. My code so far looks something like: /* this function will

Hi all - We're running a 3-node distributed volume, using gluster 3.3.1. We're seeing a rare but repeated issue, where files are written to the volume, appears to be written OK, but are not accessible via NFS or the gluster client. These files appear when we inspect the bricks directly. For example, the path in question is

Hi Tomas, Thanks for this explanation. As you can probably tell I'm not much of a C person, so I didn't realise this change would be invisible to C users. I suppose R's stability contract only applies to C, and therefore changes that break other languages such as Rust are out of scope. You are right that this error is confused by bindgen's inability to handle anonymous types, but

o `Rcomplex' is preferred to `complex' (a future reserved word in C) for R complex objects passed to C. I'm a bit confused here. Is "complex" or "Rcomplex" the future reserved word in C (I thought "complex" already was, but I'm not a C programmer) and is this because R storage modes should or should not have names corresponding to C reserved

Duncan, here is part of the assembly around the problem area. I used gcc -S -flto to generate the .s file, llvm-as on the .s fiile will show error: invalid cast opcode for cast from 'i40' to 'float' %638 = trunc i40 %637 to float %633 = bitcast i8* %632 to float* %634 = bitcast float* %633 to i40* %635 = load i40* %634, align 1 %636 = shl i40 %635, 7 %637 = ashr i40

I don't think an auto-generated name (along the lines of u or u2) for the anonymous structs would be helpful here. You can see that bindgen is already generating a placeholder name ("__bindgen_anon_1"). A meaningful name might be nice instead, but I get the impression that isn't an option here since that would break the C API. Can I ask, would it make sense for us to hard code

Duncan, Thanks for getting back to me. I am not sure how to find the original bitcode (and related Ada source code) that causes the truncate. This is the error message that gcc gave me when I tried to compile an Ada source file using dragonegg plugin (gcc -c -fplugin...).
