Installing R from source: "../i386/ldpaths: No such file or directory"

Marius,

Hi,

I tried to install R from source on a new MacBook Air running 10.7.1. I followed the steps in the R-Faq and did:

(1) installed Xcode 4.1
(2) installed a *corresponding* Fortran compiler from
http://r.research.att.com/tools -> "Apple Xcode gcc-42 add-ons" [the
correct version for Xcode 4.1 on Lion was gfortran-lion-5666-3.pkg]
(3.1) downloaded and unpacked the latest R sources from CRAN (R-2.13.2.tar.gz)
cd ~/Downloads
(3.2) chose the architecture (x86_64, i386, ppc or ppc64):
arch=x86_64
(3.3) created a build directory 
mkdir build
cd build
(3.4) configured R
../R-2.13.2/configure r_arch=$arch  CC="gcc -arch $arch" \
    CXX="g++ -arch $arch" F77="gfortran -arch $arch" \
    FC="gfortran -arch $arch" OBJC="gcc -arch $arch" \
    --x-includes=/usr/X11/include --x-libraries=/usr/X11/lib \
    --with-blas='-framework vecLib' --enable-BLAS-shlib --with-lapack
(3.5) built R
make -j8
(3.6) installed R in /Library/Frameworks
sudo make install
(FWIW: you don't need sudo if you are admin. If you use sudo once, you have to use it always.)
(4) made R visible from the command line
sudo ln -s /Library/Frameworks/R.framework/Resources/R /usr/local/bin/R 

(FWIW: the canonical location is /Library/Frameworks/R.framework/Resources/bin/R)
Executing R in the shell (even after restart) brought:
bash-3.2$ R
/usr/local/bin/R: line 229: /Library/Frameworks/R.framework/Resources/etc/i386/ldpaths: No such file or directory

The framework installation uses `arch` to determine the default architecture which in your case is i386 but it is not installed. You can edit

/Library/Frameworks/R.framework/Resources/bin/R

and replace 
: ${R_ARCH=/`arch`}
with
: ${R_ARCH=/x86_64}

The assumption is that if you use a framework the resulting R will be universal, but it your case it's not. I'll see if we can come up with something more robust ...

Cheers,
Simon
I found a similar something similar on https://stat.ethz.ch/pipermail/r-help/2007-December/147771.html but it was not answered. 

wrong list ;)
I check with the installation (from binaries) on another Mac. There the folder /Library/Frameworks/R.framework/Resources/etc contains "i386", "repositories", and "x86_64", but for the new installation, I only found subdirectories "repositories" and "x86_64". 

Cheers,

Marius
