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

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:

Hello, I'm trying to compile a library in MS Visual C++ using R.dll. For that, I need R.lib for linking. Where can I get it? "Readme.packages" for R says: "First build the import library R.lib by lib /def:R.exp /out:Rdll.lib" But for this, I need R.exp, that is also not provided with R installation (Lib.exe output: LIB : fatal error LNK1104: cannot open file

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

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 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

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

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

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

We also have a few other suggestions and wishes about backtrace storage and display on the one hand, and display of constructed calls on the other hand. Perhaps it would be better to open a different wishlist item for traceback() to keep the discussions focused? FWIW I think deparsing backtraces lazily is a great idea. Displaying 1 line per call by default in interactive sessions, while being

Hello, I am using cygwin (latest version) and I managed to generate a dll partly with rcmd shlib although there was a problem with both the resouce file (I had to remove "FILEOS VOS__WINDOWS32") and the command line for gcc (--shared is not supported for instance). So I would like to know which compiler/environment you advise to use for windows OS. Then I could load the library in R

I am trying to port some C code from S-Plus (7.0.6) to R (2.4.0) under Windows XP SP2. I use Visual C++ 6.0 to build my library for S-Plus, so I'd like to stick with that set up, if possible. According to the README.packages file, I need the file R.exp (containing functions exported from R.dll, I'm guessing) to build an R package with VC++. >From what I've read in the archives of

Hi, I'm trying to cross compile R260 in a ubuntu 6.06 linux. I downloaded the Makefile for 251 and simply replaced the R version by 260. However I'm getting an error about mingw. ernesto at gandalf:~/ipimar/devel/R/ccompile260$ make R export

Hi all, I try to create an import library for using dll. Following the instruction in the readme.package, I used the command “lib /def:R.exp /out:Rdll.lib”, however, the error message showed “Cannot open file R.exp”. I downloaded the source code R-1.9.0.tgz, but I can not find R.exp. Thanks! Rui Phone: (403)220-4501 Email: rwang@math.ucalgary.ca Department of Mathematics and Statistics

Dear All, I have a pair of .cpp and .def file can be compiled using VC++ and works perfectly well in S-PLUS. I wanted to do the same for R; so I followed the guidline given in "Building from a source-code library under Windows" as much as possible and manage to compile them using VC++ and call it from R. But it gives different answer from the one called from S-Plus. I know that I did

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
