Hi Eli, Thanks for your rapid response! Now I have another question. How&nbsp;to&nbsp;get LLVM bc files successfully by compiling test.c and static libraries ?

Sorry could you help me? I have problem with using LLVM and some code in C (.so file) I want to use (simply example): mylib.c: #include <stdio.h> void printString(char *str) { printf("%s", str); } mylib.h: #ifndef MY_LIB_HEADER #define MY_LIB_HEADER void printString(char* X); #endif /////////////////////////////////////// Normally in C++ I do this: g++ -fPIC -c mylib.c

Hello, I 'd like to use some functions in myLib. So I do: library(myLib) Then I get this message: Error: package 'myLib' is not installed for 'arch=i386' > sessionInfo() R version 2.13.2 (2011-09-30) Platform: i386-pc-mingw32/i386 (32-bit) locale: [1] LC_COLLATE=French_France.1252 LC_CTYPE=French_France.1252 LC_MONETARY=French_France.1252 LC_NUMERIC=C

I am using the .Call interface to call c++ code from R. For that, I am trying to create a dynamic library (mylib.so) using "R CMD SHLIB" by linking my own c++ code and an external c++ library (blitz++). The makefile works fine on my Mac, produces mylib.so and I am able to call .Call() from R, but on a linux server (I think Debian), I got the following error: ---------- /usr/bin/ld:

hi all, i posted a question before about this, but i may have been too cryptic to understand. in short, there exists an R package that someone is writing. this package depends on a custom library (written in C,), compiled as a shared, and called by the package's functions via the .Call(...) method. we are testing out different code implementations of the compiled library functions, and thus

Dear R users, we are trying to build a R package that includes a precompiled shared library, let's say mylib.so. We created the skeleton of the package and we moved the mylib.so file into the libs folder that we created at the same level of the folders man and R. Moreover we created the file NAMESPACE and we added the line useDynLib(mylib, .registration=TRUE). The building step seems to work

Hi, Standard approach to profiling dynamically loaded libraries with gprof doesn't seem to work with LLVM: export LD_PROFILE=Mylib.so export LD_PROFILE_OUTPUT=. make ENABLE_PROFILING=1 // compiling my project opt -load Profile/Mylib.so -options... but no Mylib.so.profile (or gmon.out) is produced. Profiling libc.so.6 usage by "ls -l", however, works fine. Could anyone explain

hi, i'm having some trouble getting a package to load a shared library object in .onLoad(...) i have a shared object file, say "mylib.so". if i start an R session, and via the CLI specify the actual library via: > dyn.load("mylib.so") everything works quite well (i.e. i can then follow with some .Call (...) methods) now, i'd like to include this shared library in

I am only reporting this because it is the current release branch and not devel. R-2.13 from svn revision 55957 builds fine, but fails make check. This happened with a fresh svn checkout 12 hours ago and it still happens as of now. Two days ago I could build R-2.13 and it passed make check on the same system, so I doubt it is a system problem. But just in case my system details are a fresh

Hello, I've been using R for about 3 years now and I'm pretty sure this is a bug. I'm using R 2.2.0. The way R is set up to get packages from CRAN using install.packages is really convenient --- if you are installing to your system's main package directory. However, I observe the following problem: I want package X but it requires package Y. Further, I have neither package

Hi all, I'm having some problems in loading libraries. I wonder if anyone can help me with this. I have created two libraries with the same name at different locations. I want to use both of them, one at a time. So I do: library(mylib,lib.loc1) (....) detach('package:mylib') library(mylib,lib.loc2) The problem is that, after this, the used library is still the one first loaded.

Hi, I'm trying to write modified versions of R save/load functions which read from/write to a char array instead of a file pointer. I want to compile my functions into a library and dyn.load them. Of course the new functions mySave/Load will use some of the internal R functions used by save/load, for example "MarkSave" (to be found in .../src/main/saveload.c). I declared them as

You can call them the same way a C++ file compiled with llvm-g++ would call them. Essentially, it's complicated enough that you probably don't want to do it for any interface of

Hi, How can I call C++ libraries (LLVM & Qt for example) from a language that's implemented on top of LLVM? Thanks, Jules -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.llvm.org/pipermail/llvm-dev/attachments/20090619/4621508b/attachment.html>

Hi, I have built a library that consists of a piece of C code and some R functions. To build it into a library that I can load using library() command, I have followed "Writing R Extensions" and made sub-directories such as mylib/R and mylib/src. But when I run R CMD INSTALL mylib, nothing seems to be happening with src directory, i.e., no C compiling. I have probably missed some key
