Dear all,
I'm trying to compile FORTRAN code to be used in R, failing miserably. I got
a simple code function to try to figure out what is going wrong. Here is the
code (available on the web) :
subroutine bar(n, x)
integer n
double precision x(n)
integer i
do 100 i = 1, n
x(i) = x(i) ** 2
100 continue
end
1. I compiled the code using 'R CMD SHLIB bar.f' in the terminal. This
created files .o and so of the same name. Got the following output in the
terminal :
R CMD SHLIB bar.f
gfortran -arch x86_64 -fPIC -g -O2 -c bar.f -o bar.o
gcc -arch x86_64 -std=gnu99 -dynamiclib -Wl,-headerpad_max_install_names
-undefined dynamic_lookup -single_module -multiply_defined suppress
-L/usr/local/lib -o bar.so bar.o -lgfortran
-F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework
-Wl,CoreFoundation
2. Tried to dynamically load the code. In the R console, typed
> dyn.load("~/Documents/Marietravail/articles/MRTspatial/SIMSSDenR/bar.so")
Erreur dans
dyn.load("~/Documents/Marietravail/articles/MRTspatial/SIMSSDenR/bar.so") :

6): no suitable image found. Did find:
/Users/maryh2002/Documents/Marietravail/articles/MRTspatial/SIMSSDenR/bar.so:
mach-o, but wrong architecture
I have :
Mac OS : 10.6.4
R 2.11.0 GUI 1.33 Leopard build 32-bit (5582)
Xcode version 3.2.3 64-bit
Installed gfortran 4.3.2
I hope this is all you need, feel free to ask me for any more info. Thank
you for your time,
MH
