similar to: [LLVMdev] Profiling dynamically loaded libraries

Hi, I am working on an R package which includes some C routines. I would like to profile the C routines (built with GCC under Debian Linux). I tried running R with LD_PROFILE=/path/to/C/library.so R and executing functions that would invoke the code therein. The code takes about twice as long to run with LD_PROFILE set than without, so I am guessing that profiling is taking place. However,

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, I am trying to obtain basic block profiles for mediabench g721 benchmark. I have successfully built llvm in profile_enabling mode. Then so as to find out the block execution frequency, I ran the command, analyze encode.out-cbe. It generated gmon.out which I read using gprof. However, I did not get the basic block level execution frequency. Can anybody help me as to how I can extract the basic

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

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, 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

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

No matter how I try, I can't seem to get a library profile from sprof on CentOS5. Does anyone know if sprof actually works on CentOS5? I'd be very interested to hear if anyone is using it successfully. At the moment I'm trying something like this to get the dump: LD_LIBRARY_PATH=. LD_PROFILE=libmy.so ./mymain where libmy.so is the library I want to profile, and mymain is the

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 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, 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
