similar to: Compiler-specific flags with PKG_CFLAGS

Why is it that R places CFLAGS after PKG_CFLAGS and not before when compiling a package (e.g. through R CMD build pkg)? This can be problematic if, for instance, you want to use -O3, but -O2 is in R_HOME/etc/Makeconf. If -O2 (in CFLAGS) appears after -O3 (in PKG_CFLAGS), you are left with what you didn't want: -O2. In R-exts, it says that "Flags which are set in file etc/Makeconf

Hi, I'm searching for a way to override the default CFLAGS/FFLAGS (-g -02 in my case) per package (e.g with "-g" for packages under development). PKG_CFLAGS/PKG_FFLAGS is prepended to the remaining flags, so it can't delete a globally set "-O2" flag. Of course I can edit the global Makeconf file, but I was wondering if there is a possibility to override variables from

Hi, what is the correct way to specify a C standard in a package's Makevars file? Building a package with e.g. PKG_CFLAGS = -std=gnu11 does work but R CMD check issues a warning: * checking compilation flags in Makevars ... WARNING Non-portable flags in variable 'PKG_CFLAGS': -std=gnu11 (Same for -std=c11.) Thanks! Regards, Andreas Kersting

Hi. I am writing some code in C that I would like to link into R. My Makevars file is: PKG_CPPFLAGS=-I/usr/local/include PKG_LIBS=-L/usr/local/lib -lgsl PKG_CFLAGS = -Wall -O0 -g -p -pg The source file is core.c,. and I am compiling using R CMD SHLIB core.c The output is gcc -arch x86_64 -O3 -g -p -std=gnu99 -I/Library/Frameworks/ R.framework/Resources/include

Dear R-developers, I am trying to reproduce the autoconf.ac example from R-ext and fail.

Hallo, does a package for Matlab exist in R? If yes, where can I find it and how can I install it under R? Thanks, Corinna

Dear all, As previously submitted, I wrote an extending pdf device to embed pop up text and web links. (Patches are available at http://pdf2.r-forge.r-project.org/patches) Now, I'm making a library version of the pdf device. However, with my skill, I'm not sure about writing Makevars or configure file for multi platforms. A following line in Makevars works on my mac, -----

Dear friends: I have been trying to install MSOffice using Crossover. I have an old license from 2002, which entitled me to install the Crossover Plugin and the CrossoverOffice Set up. Support for them has expired, but both programs uinstalled fine into their own directory in KDE. But I do have a problem installing MSOffice. I keep getting the error message "Unable to get a list of

Hello! I have some Fortran code that uses BLAS calls, and would like to compile it into a shared object to call it from R as per the "Writing R Extensions" manual. What needs to go into the "Makevars" file, so that running the R CMD SHLIB will work in Ubuntu? The code compiles properly on the Mac, with the Makevars line PKG_CFLAGS=-Wl,-framework -Wl,vecLib but of course

Hello, I thought that I should try openblas when building a CRAN package containing lots of old (twentieth century) C-code with frequent calls to blas and lapack routines. I have the following options on my Ubuntu 20.04 machine: Selection Path Priority Status ------------------------------------------------------------ * 0

I have been working on an R package that calls C code using .C(). I recently started including some functions from the GNU Scientific Library in my code. The code runs fine on my machine when not wrapped in the package. But I get the following error from "R CMD check" * checking whether the package can be loaded ... ERROR Loading required package: splancs Loading required package: sp

Hi, I'm trying to get C code working with R. This is my first time writing C on Windows and I'm making a mess of it. Help! I'm following the example in Roger Peng's "An Introduction to the .C interface to R". The C code is: #include <R.h> void hello(int *n){ int i; for(i=0; i < *n; i++) { Rprintf("Hello, world!\n"); } } I seem to be unable

Full_Name: Rick Sayre Version: 2.4.0 OS: Windows Submission from: (NULL) (138.72.27.164) PKG_LIBS works fine on *nix on windows, it seems to be ignored by the "SHLIB" script so, R CMD SHLIB blah properly uses PKG_CPPFLAGS and PKG_CFLAGS from Makevars, but PKG_LIBS is ignored

We have an R package which needs to include a JAR file. Is there a canonical directory for it?

Is there a means to split a vector into its individual elements without going the brute-force route for arguments to a predefined function call? offred.rgb <- c(1, 0, 0) * 0.60; ## Brute force style offred.col <- rgb(offred.rgb[1], offred.rgb[2], offred.rgb[3], names = "offred") ## Desired style

Hi, Similar questions have come up before on the list and elsewhere but I haven't found a solution yet. winbuilder's install.out shows data.table's .c files compiled with -O3 on Win32 but -O2 on Win64. The same happens on R-Forge. I gather that some packages don't work with -O3 so the default is -O2. I've tried this in data.table's Makevars (entire contents) : ====

Dear R-devel, I've written a numerical solver for SOCPs (second order cone programs) in R, and now I want to move most of the solver code into C for speed. I've written combined R/C packages before, but in this case I need to do matrix operations in my C code. As I have never done that before, I'm trying to write some simple examples to make sure I understand the basics. I am stuck
