similar to: Cannot override default -O3 flag on Winodws, dll does not have symbols

Hello, Does xen-unstable or Xen xen-3.0.4_1 (or lower) support live migration of winodws based domUs? did anybody tried it ? Regards, Andy _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

When I install an R package with cpp codes such as rrcov via CRAN (under R 3.1.1, using no Makevars file and under Ubuntu 14.04 using GCC 4.8), the cpp code is compiled with the -o3 flag (in fact, looking at the Makeconf file this seem to again be the default since R 3.1.1) But when I install my own package via CRAN it is compiled with the -o2 flag. My questions are what is causing my

I have a question about how one can modify or override the compilers that R uses for package installations? Or if perhaps this configuration is in some editable file somewhere. Initially I built the version of R 2.15.1 on Solaris SPARC (virtual T4), but found out the build was done as 32 bit. After some research, I found that the pre-compiled GCC version I had only allowed for 32 bit. I wanted

Hello, I'm tring to install a Rpackage that holds some C//C++ code as far as I understood the R library generic compilation mechanism, compilation of C//C++ sources is controled 1) at system level by the ocntentos RHOME/etc/Makeconf 2) at user level by the content of ~/.R/Makevars 3) at package level by the content of src/Makevars Problem I have is that src/Makevars is ignored see

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

Hello, I'm writing an R package that is mainly written in C++. By default, R CMD INSTALL creates C/C++ flags as follows: -g -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 -g However, my package is fairly large. With debug info compiled into the library, the generated .so file is over 200MB. Without debug info, it's about 30MB. I hope

Hi, I am trying to package some code to use with R and wanted to call Rscript from within the Makevars file (I am trying to automate the setting of the location of a third party library depending on what is available / the system the package is being installed on). If I just have a simple Makevars containing PKG_LIBS= -lnag_nag -L/fserver/nagprod/FL22/fll6a22df/lib the package is built

Hello, In the src folder of my R package I have a.cc b.cc f/g/x.cc my Makevars.in has all: $(SHLIB) upon installing only, a.o and b.o is build and the final dll is comprised of a.o and b.o How can I instruct $(SHLIB) to pick up its source files from all subdirectories (or maybe a subset, though here it will be all) in src ? Much thanks Saptarshi

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

Hello, I'm using a Makevars.in file and running my code through gdb. I understand i should turn of -O2, but R's makeconf overrides my settings /ln/meraki/custom/lib64/R/etc/Makeconf:112: warning: overriding commands for target `.cc.o' in Makevars.in .cc.o: g++ -g ${PKG_CXXFLAGS} ${PKG_LIBS} ${RINC} ${RLIB} -c $< -o $@ Thank you S.

Hello, I'm curious to know how people are calling R from web applications (I've been looking for Perl but I'm open to other languages). After doing a search, I came across the R package "RSPerl", but I'm having difficulties getting it installed (on Mac OSX). I believe the problem probably has to do with changes in R since the package release. Below you will see where

OK: despite Dirk's very kind help, I decided that trying to deal with R configuration and Debian configuration simultaneously was too difficult. I did manage to solve my problem by reconfiguring/making/ installing all of 2.3.1 from source: ./configure F77=/usr/bin/g77 make make install A few questions inspired by this experience: (1) it seems a bit odd that R sets F77=gfortran by

Does anybody know why two "-g" flags appear in the call to gcc in R CMD SHLIB Example: gcc -std=gnu99 -I/usr/share/R/include -DNDEBUG -fpic *-g* -O2 -fstack-protector --param=ssp-buffer-size=4 -Wformat -Werror=format-security -D_FORTIFY_SOURCE=2 *-g* -c c_file1.c -o c_object1.o Surely it need only be listed once?

Hi all, I am having some problems in updating some packages from source. I start with : install.packages("Boom",lib="C:/RownLib",type="source") I get the following error message : * installing *source* package 'Boom' ... ** package 'Boom' successfully unpacked and MD5 sums checked ** libs *** arch - i386 c:/Rtools/mingw_32/bin/g++ -std=gnu++11

I am running into the following issue that has been previously reported on the R-devel mailing list. The short version is that I'm writing a package for MPI, and I'd like to change CC and SHLIB_LD to "mpicc". Trying to change them in Makevars.in has no effect, because the values are clobbered by /etc/R/Makeconf. Will the following changes to Makeconf.in introduce any problems?

Dear People, I want to run gcc with optimisation turned on (-O2), and with -Wall (all warnings) enabled, when using R CMD SHLIB. When I do make, which is R CMD SHLIB -Wall -O2 cftp.c mcmc.c latticefn.c -lm in this case, I get faheem ~/research/cftp>make R CMD SHLIB -Wall -O2 cftp.c mcmc.c latticefn.c -lm make[1]: Entering directory `/home/faheem/research/cftp' gcc -I/usr/lib/R/include

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
