Dear all, after trying to compile R on our IBM Power3/AIX 5.1 machine I've been able to run it correctly. First of all I would thank all who responded my mails. I explain here how I've done it: First of all, it seems that configure and some shared libraries of AIX does not work at the same time. I tried to configure & make with the following environment vars CC=xlc F77=xlf CCC=xlC

Hello List, Knowing I would eventually need to ask for help on the list, I've held off my thanks and congratulations on the 1.+ releases of R. I am amazed at the dedication of the R-core team, and do add my applause and thanks. I've had a compile problem with the latest version which has not occurred before. I'm compiling under: platform sparc-sun-solaris2.6 arch sparc

Up to now I have got the base R and about half of the packages working on SuSe Linux 5.3 using gcc, g77 and xdevel. The other half, for example: pspline, logspline, KernSmooth, akima, tripack, ppr, principal.curve, cluster, funfit, repeated, event, etc., just won't install. Some of them give warnings at expressions in subroutines (repeated, event, pspline,etc.. I will ask about this in

Hi - I'm trying to build R 1.6.1 on a Powerbook running Macintosh 10.2.2 with the most recent software update. The latest version of the developer tools is installed. I have also installed g77 and f2c from fink (the binary versions, using apt-get). ./configure fails with the following error: > checking for dummy main to link with Fortran 77 libraries... unknown > configure: error:

I have downloaded the source code for Linux. the ./configure procedure can find gcc but cannot find f77 or f2c I have looked for the above compiler with Test and installed all what pertains to Fortran. Still not even the man pages for f77 anf fc2 work >. Where is f77 and f2c with linux 10.3 ?? Thank you do much -- Maura E.M [[alternative HTML version deleted]]

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

I have R-0.62.3 and RedHat 5.0 with fort77. At the office R is running but when I install a package, eg. 'akima' I get a message make: f77: Command not found 'R INSTALL library' does not accept fort77, but R installation checks f77/g77/fort77. Is there an easy way to edit some file and replace f77/g77 with fort77? At home I have the same R and Linux versions, but when

Hi, I've found that the default options of gcc and g77 on alpha produce an executable that suffers from floating exceptions. There seems to be a problem with the configure scripts that prevents the --with-f77 option working correctly. The configure script tests that f77 is running by attempting to compile and link a dummy program - the link step seems broken on the alpha (it doesn't like

We have a user here who is attempting to compile a package which requires f90 (gfortran will do). Our version of R was built with f77 (g77). When the user attempts to build the package, f77 is always invoked and fails due to the presence of f90 features. Is there a simple method or some documentation on how to force a package build to use a different compiler than the one used in

Hello, I use Gentoo and I can't get R 2.0.1 to compile. I used the portage system, Gentoo's source package sytem, and after it uncompresses the source to R, it says that I don't have a fortran compiler. It told me to use f77 flag and re-emerge gcc, which I did with the f77 and fortran flags, but it still won't compile. Does anyone have any ideas? I suspect that gcc has changed

Dear Dirk, I have had the exactly same problem like Ivo and his solution worked for me. Hence the USE=f77 flag is NOT a typo but a Gentoo quirk. As far as modifying the configure script is concerned, I believe that it is certainly possible to perform said check (if 'f77 --version == f2c' then die) only on x86_64 platforms. And I'd argue it is f2c's fault. AMD64 linux distros have

Anyone know what the problem is with IRIX 6.5 ? (esp if there is a solution?). Looks like the built-in math stuff is masking definitions from R source.
