Hi All,
I have been struggling to figure out how to compile c codes for R use.
I am using Win XP + Cygwin + R binaries.
After I followed all the instructions in " Building R for Windows"
from Murdoch's website, I tried to Run something like :
R CMD SHLIB C:\R\test.c , but still didn't get any output.
My first question is, does this mean I already did something wrong ?
Anyway, I assumed that I need to run this command in Cygwin, so I started
to reinstall R in Cygwin by compiling the source (I assume it is not possible to
call the precompiled binaries from Cygwin). But I ran into the following
problem when I ran "make all recommended" in src/gnuwin32/
$ make all recommended
make: ./Rpwd.exe: Command not found
make[1]: ./Rpwd.exe: Command not found
make --no-print-directory -C front-ends Rpwd
make -C ../../include -f Makefile.win version
make Rpwd.exe
gcc -O3 -Wall -pedantic -I../../include -c rpwd.c -o rpwd.o
rpwd.c:22:20: direct.h: No such file or directory
rpwd.c: In function `main':
rpwd.c:42: warning: implicit declaration of function `chdir'
rpwd.c:45: warning: implicit declaration of function `getcwd'
make[3]: *** [rpwd.o] Error 1
make[2]: *** [Rpwd] Error 2
make[1]: *** [front-ends/Rpwd.exe] Error 2
make: *** [all] Error 2
Can I get some help with my quesitons , and some suggestions concerning the best
way to solve the whole problem ?
THanks a lot for your help..

The usual problems are either missing components from the installation steps outlined in Building R for Windows, or an incorrect PATH variable so that windows or cygwin versions of programs are used rather than MinGW / Rtools. Also, this question belongs on the R-devel list, where those doing development work are more likely to see and respond to your questions.

If you do, you probably need to use forward slashes but it may well not do what you expect. Did you really get no output at all? Please use the correct list (R-devel: see the posting guide) and supply verbatim copies of what you did.> My first question is, does this mean I already did something wrong ? > > Anyway, I assumed that I need to run this command in Cygwin, so I > started to reinstall R in Cygwin by compiling the source (I assume it is > not possible to call the precompiled binaries from Cygwin).
