Hi r-devers,
This is the first time I've tried to install a package from source on
Windows, so please bear with me. I'm trying to install a package written
(and tested) by a colleague in C for R on linux, and I am trying to
install it on windows following the directions here -
http://cran.r-project.org/doc/manuals/R-admin.html#The-Windows-toolset
and here - http://www.murdoch-sutherland.com/Rtools/
I installed Rtools (but not InnoSetup or LaTeX because of permissions
problems on my PC, although I don't think they are essential). I checked
my environment variables are pointing to the correct tools, and then I
ran the following:
R CMD INSTALL --library="C:/R/library" --no-chm PP
The package is called PP, and contains the following files:
>ls -R PP
PP:
DESCRIPTION R man src svn-commit.tmp~
PP/R:
PP.R
PP/man:
PP.Rd pp.get.longs.Rd pp.ppw.Rd pp.strip.extra.Rd
pp.close.file.Rd pp.open.file.Rd pp.print.Rd pp.write.Rd
pp.get.lats.Rd pp.ppa.Rd pp.read.Rd tmp
PP/src:
PP.c PP.o PP.so makefile.old
The result is (based on my limited knowledge) quite promising, but it
seems to be unable to link libraries. Here's what I get:
* Installing *source* package 'PP' ...
** libs
making DLL ...
gcc -shared -s -o PP.dll tmp.def PP.o -LC:/PROGRA~1/R/R-29~1.2/bin -lR
Cannot export SwapEndian: symbol not found
Cannot export close_file_c: symbol not found
Cannot export open_file_c: symbol not found
..... Etc ....
I don't have any experience compiling C code, so I'm a bit stumped. Do I
need to override the default gcc settings by editing the makefile? Or
have I missed something more obvious? Please let me know if you need any
additional info.
Kind regards,
Andy
