I am experimenting with exporting pointers to some of the functions in deSolve so that other packages may import them, using the 'R_RegisterCCallable' mechanism. I have added a header file and some other C code in inst/include of the deSolve source package that need to be accessible to other packages. I have a site-library set up in Rprofile.site where all installed packages go, and as long as my experimental version of deSolve is installed there, I'd like to install my modified copy of deSolve in a test library. However, when I try to install my test package (which includes both Depends: deSolve and LinkingTo: deSolve, in its Description file, as described in 'R Extensions'), compilation fails, because the appropriate C code cannot be found (there is also an unrelated problem in deSolve_stubs.c triggering the "unexpected ')' before '*' token" error).
[test]$ R CMD INSTALL -l C:/home/Rlib-test dma ---------- Making package dma ------------ adding build stamp to DESCRIPTION installing NAMESPACE file and metadata making DLL ... gcc -std=gnu99 -Ic:/PROGRA~1/R/R-28~1.1PA/include -I"C:/PROGRA~1/R/site-librar y/deSolve/include" -O3 -Wall -c R_init_dma.c -o R_init_dma.o R_init_dma.c:1:27: error: deSolve_stubs.c: No such file or directory R_init_dma.c:3: error: expected ')' before '*' token make[3]: *** [R_init_dma.o] Error 1 make[2]: *** [srcDynlib] Error 2 make[1]: *** [all] Error 2 make: *** [pkg-dma] Error 2 *** Installation of dma failed *** Removing 'C:/home/Rlib-test/dma' It seems that although the 'site-library/deSolve/include' folder is included in the search list for included files, the 'Rlib-test/deSolve/include' folder is not. The folder that includes both the experimental version of deSolve and the test package dma also contains a .Rprofile file which places 'C:/home/Rlib-test' at the front of the library search path, and I have confirmed that this is so (in fact, the above INSTALL command does not need the '-l ' argument; the default install location is Rlib-test for installs from this folder). It looks as if the code in INSTALL that sets up the -I arguments to gcc does not find the library path defined for this folder. Can someone point me to the right way to do this?
