similar to: a plead to package developers regarding GCC

Dear R-devel, [I'm not sure if this is appropriate for R-devel. If not, I'm more than happy to move it to R-help.] As those of you who saw my post on R-help know, I've been trying to build R-patched on a dual Opteron box running Scyld Beowulf, using the PGI 6.1 compilers. The build went fine, but I couldn't get it to pass make check-all. Jennifer Lai, who reported success with

Hi All, While attempting to build R-patched using the Portland Group compiler suite on our dual Opteron 250 box running Scyld 29cz5 (based on RH, kernel 2.4.29), I get: make[5]: Leaving directory `/home/andy/Rbuild/R221-pgi/src/library/tools/src' make[5]: Entering directory `/home/andy/Rbuild/R221-pgi/src/library/tools/src' pgcc -I../../../../include -I/include -I/include/CC -fpic

Dear R-help, I'm trying to build R-2.4.0 on our Opteron-based Scyld cluster. The system has gcj (the GNU Java compiler, part of GCC) stuff in /usr/bin. When I installed jdk 1.5.08, the install script placed it in /usr/java (I didn't have a choice, as the script didn't offer that option). Now when I run configure in R-2.4.0, it finds gcj, which is not what I want to use. Is there a

Before I do that, I would need to remove the gcj stuff that are in /usr/bin. If I know how to remove gcj, I'd gladly do that. However, for the particular version of the OS, the entire GCC seems to be bundled into one rpm, and I could not remove just the gcj component. Neither do I wish to mess with files that are part of some RPMs--- in my experience that's invitation for trouble later.

Dear R-help, Has anyone tried running R on a Beowulf-type cluster? I can get R to run in batch (using R CMD BATCH) on a cluster, but am wondering if it is possible to get an interactive R session on a compute node. Right now, if I run: beorun --nolocal R I just get the R start-up message and back to the shell prompt. If I try bpsh 0 R I can get R started (but the R prompt does not

Dear R-devel, A while ago Prof. Ripley had mentioned that g77 on AMD64 isn't the greatest, and the Salford Fortran is likely to be better. My question is, has anyone tried compiling R with Salford compilers (or other commercial compilers)? If so, do they offer performance advantages over GCC? TIA for any info.

Dear R-devel, Can anyone give me some hints on how to go about debugging a strange segfault in my randomForest package? Here's the scoop: A user reported segfault when running predict() in the randomForest package. I asked for the data and code. The combination runs fine under WinXPPro, but does give segfault on one of our Linux boxes running R (1.7.0 through R-devel_2004-01-08) on

Dear all, Has anyone seen the same problem? I tried compiling R-1.9.0 alpha (2004-03-16) on our Opteron box running SUSE Linux ES8. I ran: ./configure --enable-R-shlib --with-blas=goto and got: Source directory: . Installation directory: /usr/local C compiler: gcc -m64 -O2 -g -msse2 -march=k8 -Wall --pedantic C++ compiler: g++ -m64 -O2 -g

For those interested: I compiled R-1.9.0beta_2004-04-02 with pgf77/gcc/g++ and g77/gcc/g++, both _without_ fast BLAS. Both passed make check-all. Simple crossprod(m) for fairly large `m' shows that the version compiled with pgf77 is about 15% faster: [andy@leo:scratch]% echo "set.seed(1); m <- matrix(runif(5e7), 1e4); gc(); system.time(crossprod(m))" | R-1.9.0-PGI/bin/R

Hi all, I've only now noticed that on our Opteron boxes running Suse Enterprise Server 8 that R-2.0.1 did not pass make chek-all. It bombed in tests/lapack.R at: > eigenok <- function(A, E, Eps = 1000 * .Machine$double.eps) { V <- E$vect lam <- E$values stopifnot(abs(A %*% V - V %*% diag(lam)) < Eps, .... [TRUNCATED] > Ceigenok <- function(A, E, Eps =

As of quite recently I experience failures to compile source packages.

Working on a Red Hat (not Mandrake) Linux and trying to load my library I get (sorry, can't copy it all, working remotely) gcc -shared -o ..... /user/bin/ld: cannot find -lg2c Does anyone know what the g2c library iss, and if I can download and compile it for Red Hat (I definitely didn't mean to type f2c in the above) Thanks Jonathan

Hi, there I'm totally new to this. I used to use SPLUS, but think maybe useful to try R at home. But seems it doesn't like me. I got error message says ld: cannot open -lg2c: No such file or directory My OS is openlinux 2.3. I use egcs-2.91.66. I searched under /lib/egcs-2.91.66/ but found no libg2c.a. There's only a libgcc.a. Thought maybe g77 people changed

Dear R-help, Can some one tell me how to profile compiled code dynamically loaded into R? Here's what I tried on our dual Opteron running SUSE Linux Enterprise Server 8 (GCC 3.3): Start with R-patched dated 2004-06-07: (I also had MAIN_CFLAGS="-pg" in config.site.) R is now configured for x86_64-unknown-linux-gnu Source directory: . Installation directory:

Dear R-help, I am trying to build R-2.2.0-patched (2005-11-07 r36217) on the head node of a Scyld cluster (dual Opteron 250s) using PGI compilers (v6.0). I used the flags suggested by Jennifer Lai on R-devel (taken from R-admin, except that I had to add -L/usr/X11R6/lib64 to LDFLAGS). The build went fine, but make check-all failed when running tests/Examples/graphics-Ex.R, at: > plot(1:2,

Dear R-devel, I'm trying to compile R-1.9.0beta (2004-03-31) with the PGI compilers (15-day free evaluation: after the 15 days the binaries will stop working). I'm running into some problems, that I hope some can offer pointers. 1. After configure, the FLIBS include /usr/local/lib' --- note the extra '. I had to manually delete it in a couple of places. In a previous thread on

Dear R-help, This one is probably a piece of cake for regexp masters. I'd like to split a character vector (for simplicity, say of length one for now) that contains fields that are delimited by arbitrary number of white spaces (e.g., " a b c "). How do I get the character vector that contain the fields? In the example I gave, I've tried: > strsplit(" a b c

Dear R-help, Has anyone notice the problem that, on Windows (NT and XP), when printing a graph using the "File -> Print..." menu in the graphics window to print the graph, that line width seemed to be ignored in the printed output? For example, if I make a plot with plot(1:10, type="l", lwd=5), it looks right on screen, but when printed out using the menu, it looks like

Dear R-devel, Has anyone played with this? http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html <http://www.amd.com/us-en/Processors/DevelopWithAMD/0,,30_2252_2282,00.html> .

Dear R-help: Has anyone tried using R on the the AMD Opteron in either 64- or 32-bit mode? If so, any good/bad experiences, comments, etc? We are considering getting this hardware, and would like to know if R can run smoothly on such a beast. Any comment much appreciated.
