Frederik, Could you do me a favour? On an amd64 system, what does
$ grep FLIBS /etc/R/Makeconf show? On i386 I get [EMAIL PROTECTED]:~> grep FLIBS /etc/R/Makeconf FLIBS = -lgfortran -lm -lgcc_s and I can add -lf2c to it at compile time by changing debian/rules for fExtremese to #!/usr/bin/make -f # -*- makefile -*- # debian/rules file for the Debian/GNU Linux r-cran-foptions package # Copyright 2003-2006 by Dirk Eddelbuettel <[EMAIL PROTECTED]> include /usr/share/cdbs/1/rules/debhelper.mk include /usr/share/cdbs/1/class/langcore.mk # package name, also forced lower case cranName := $(shell grep Package: DESCRIPTION | cut -f2 -d" ") cranNameLC := $(shell echo $(cranName) | tr "[A-Z]" "[a-z]" ) ## which we can use to build the package directory package := r-cran-$(cranNameLC) ## which we use for the to-be-installed-in directory debRlib :=$(CURDIR)/debian/$(package)/usr/lib/R/site-library common-install-indep:: R_any_arch common-install-arch:: R_any_arch R_any_arch: dh_installdirs usr/lib/R/site-library ## next lines changes to MAKEFLAGS="FLIBS=-lgfortran -lm -lgcc_s -lf2c" \ R CMD INSTALL -l $(debRlib) --clean . ## from R CMD INSTALL -l $(debRlib) --clean . rm -vf $(debRlib)/R.css $(debRlib)/*/COPYING ie by adding the MAKEFLAGS="FLIBS=.... -lf2c". Could you try that? libf2c has the pow_dd symbol we got the error for. Dirk -- Hell, there are no rules here - we're trying to accomplish something. -- Thomas A.
