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:

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

Hi, This is Crystal. I have some questions about llvm-gcc. Could you please give me some advice? Thanks in advance. Problem description: Env: llvm-gcc (GCC) 4.2.1 gcc (GCC) 4.1.2 OS:fedora7 I tried to compile a C programme test.c with llvm-gcc by task: [root at localhost mylib]# llvm-gcc -emit-llvm test.c -Llibmylib.a -c -o test.bc [root at localhost mylib]# lli test.bc after running the command

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

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

...ecify these locations (and set these via `--configure-vars'). One can also bypass the configure mechanism using the option `--no-configure'. No doubt because of my inexperience, I can't quite figure out how this works. For example, if I want to set the variable LIBS to '/mylibs', how would I do this? I have tried various versions of R CMD INSTALL --configure-vars='LIBS=/mylibs' mypackage R CMD INSTALL --configure-vars 'LIBS=/mylibs' mypackage R CMD INSTALL --configure-vars LIBS=/mylibs mypackage all to no effect. (Although it is quite possible that I...

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

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

Hello, I'm trying to install R from sources on two Linux machines (both with Suse 12.2): 1. > uname -a Linux cs-wsok 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26 09:36:26 UTC 2012 (641c197) x86_64 x86_64 x86_64 GNU/Linux 2. > uname -a Linux csltok.swansea.ac.uk 3.4.6-2.10-desktop #1 SMP PREEMPT Thu Jul 26 09:36:26 UTC 2012 (641c197) x86_64 x86_64 x86_64 GNU/Linux I am trying version

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

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

...my C functions perfectly. now i want to build the package so i can install it easily on my colleagues' machines. so i use the normal R build mechanism (R CMD build), but first create a Makevars file that looks like so: PKG_CPPFLAGS = -I../depPkg/include PKG_LIBS = ../depPkg/lib .PHONY: all mylibs all: $(SHLIB) $(SHLIB): mylibs mylibs: (cd ..; gunzip depPgk.tar.gz; tar -xf depPkg.tar; cd depPkg; ./ configure --prefix=./lib --with-pic --disable-shared; make; make install) finally, when i try R CMD INSTALL, i know it sees the Makevars file, because the first build step shows the a...

Hi Everyone, When I used llvm-objdump to disassemble an ELF armv7 or thumb I have this error message: llvm-objdump: warning: invalid instruction encoding This message appears directly into the output and the output is mostly wrong (the invalid instruction create a shift in the addresses) : 1a6d: ff 2f e1 08 stmeq r1!, {r0, r1, r2, r3, r4, r5, r6, r7, r8, r9, r10, r11, sp} ^ 1a71: 30

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.

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, 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

I haven't been able to figure out from this thread why this attribute is necessary at all. Anonymous or unnamed namespaces were added to C++ for this very purpose, but the ISO C++ Standard does not discuss "linkage" per-se because it is outside the scope of the language specification. But it does describes it in terms of having a hidden name which is "unique" to the

Hi, Let me justify building R from source. While I can obtain R built for me under Ubuntu, I tend to build it from scratch as we use a NFS-shared build as well as shared R libraries for all the bioinfo staff at this company. Only one build and one set of packages to ensure uniformity across all workstations. My problem is that despite using a pretty standard build process, I am failing at the
