>From the R-2.6.0/doc/README.packages it says: Using Visual C++ ================ You may if you prefer use Visual C++ to make the DLLs (unless they use Fortran source!). The notes here were tested with VC++6. First build the import library Rdll.lib by make R.exp ... In the installation (R-2.6.0-win32.exe) there is no Makefile with an R.exp target that I could find and I get

Hello, The procedure for creating an import library (Rdll.lib) that is documented in gnuwin32/README.packages works fine using the i386 architecture, but it doesn't seem to work under x64. Specifically, the procedure is: pexports R.dll > R.exp lib /def:R.exp /out:Rdll.lib /machine:X86 R.dll There are two issues under x64: 1. Older version of pexports crash when applied to an x64 R.dll.

Hello, I am trying to compile ROracle _0.5-4 under R 1.9.0 without much success. I am running Windows 2000 SP4, Visual C++ 6.0 SP6, and Oracle client 9.2.0.1.0. I was able to run the pre-compiled version of ROracle_0.5-2 under R 1.7.1, but does not work on R 1.8.1 or R 1.9.0. Here is the output from nmake: C:\Program Files\R\rw1090\library\ROracle\src>nmake Microsoft (R) Program

Dear R developer, we are trying to build DLL files using Microsoft Visual C++. As stated in readme.packages, we have to build first the import library Rdll.lib with the command: lib /def:R.exp /out:Rdll.lib. However, this command gives 2155 errors due to unresolved external symbols (ATTRIB to zlibversion) in Rexp. Could anybody tell me if something is missing in the command line or suggest any

Hi I downloaded speex_win32_1.0.4_setup.exe. I was pretty happy to see that there was libspeex.lib and libspeex.dll. Everything went fine until I tried to build speexenc.c as win32 console program. Visual Studio 2005 gives error: "fatal error LNK1104: cannot open file 'LIBC.lib'". What is this LIBC.lib file? My ultimate goal would be to make wav->speex encoder

Hi, I wonder where I can find an example of using a function in LAPACK library in a user's own C code. I wrote a C program which will be compiled and linked to produce a DLL file and then loaded into R. I hope to use a function from LAPACK library, for example, dgesdd, in the program. Following R manual, I call the function by F77_CALL(dgesdd) in the program. The program can be compiled

Hi, I am trying to implement on a Win7 box the showArgs example of section 5.10.2 "Calling .External" of the R extension manual. I am using interchangeably gcc (RTools) and Visual C++ (via Makefile.win) to build a package. I get a couple of runtime oddities when the dll compiled with Visual C++. I'd value comments, observations and tips from interested readers. I tried my best to

Full_Name: Venkatesh Mysore Version: R-1.7.0 OS: WindowsXP Submission from: (NULL) (216.165.110.10) While accessing Rproxy.dll repeatedly (using the code from the (D)COM example in the R website) causes a failure in the 24th iteration. R-1.6.2 does NOT give this error. This seems to be a memory management error, that might be linked to the huge leakage difference between R-1.7.0 and R-1.6.2

Dear sir\madam! I'm trying to speed up my R code by writing quite simple dll's in C. But I faced some problems, and I cannot determine their source. #include <Rinternals.h> SEXP mycombin(SEXP N, SEXP k){ int i, *j, *l, c; j = INTEGER(k);l = INTEGER(N); c = 1; if(j[0] > 0 && j[0] < l[0]){ if(j[0] <= l[0] - j[0]){ for(i =

Hi, I am new to R. I need to communicate with Oracle from R program in windows xp. So I am planning to use ROracle. I downloaded the ROracle src from the site below: http://cran.r-project.org/web/packages/ROracle/index.html I am using R version 2.6.2 and Oracle 10g. I followed the instructions to build ROracle. When I try to compile the source src/Makefile.win I get the following error:

recently I used gcc 4.9.1 (http://sourceforge.net/projects/mingw-w64/files/Toolchains targetting Win64/Personal Builds/mingw-builds/)on windows to build R,but failed when link R.dll ,it report linker status 5.  after some digging, I found when use gcc 4.9.1 64 bit on windows there are lots of .refptr.*(* is r function name) in R.def, which lead build fail.so I add a simple path to

Hi, I need to use ROracle to communicate with Oracle from R program in windows environment. I am using Oracle 10g, R 2.6.2. I found a pre-compiled binary for ROracle for Oracle version 9.2. When I am trying to use it with Oracle 10g I get the following error: con <- dbConnect(drv, "user/passwd at dbname"); Error in function (classes, fdef, mtable) : unable to find an inherited

Hi, I have tried to disable stack checking by set R_CStackLimit to -1. However, it always crashes my win32 multiple threads program. I am using R-2.5.0. My code looks like: #include <Rversion.h> #if (R_VERSION >= R_Version(2,3,0)) #define R_INTERFACE_PTRS 1 #define CSTACK_DEFNS 1 #include <Rinterface.h> #endif and then, add below line to my main function: R_CStackLimit =

Hi, I am trying to use dynamic memory allocation in the C code to be called by R through the .C interface. I have used R_alloc as explained in the Writing R Extensions and included the R.h header. The program compiles fine but fails when linking. Obviously it needs a library file where R_alloc is found. I have tried to link by adding R.dll to list of files at the end of the link command but

When large calls cause errors R may stall for extended periods.? This is particularly likely to happen with `do.call`, as in this example with a 24 second stall: ??? x <- runif(1e7) ??? system.time(do.call(paste0, list(abs, x)))? # intentional error ??? ## Error in (function (..., collapse = NULL)? : ??? ##?? cannot coerce type 'builtin' to vector of type 'character' ??? ##

Luke, thanks for considering the issue.? I would like to try to separate the problem into two parts, as I _think_ your comments address primarily part 2 below: 1. How can we avoid significant and possibly crippling ?? stalls on error with these non-standard calls. 2. What is the best way to view these non-standard calls. I agree that issue 2. requires further thought and discussion under a
