Hello,
One of our packages contains C++ code that needs to be compiled against
2 other packages. So the LinkingTo field in DESCRIPTION looks like this
LinkingTo: FLCore,FLash
Both packages are also in the Depends field.
In R 2.6.2, first thing we noticed was that both names could not have
any space between them, althoguh the example in the html version of
"Writing R Extensions" does have one:
"A package that wishes to make use of header files in other packages
needs to declare them as a comma-separated list in the field LinkingTo
in the DESCRIPTION file. For example
Depends: link2, link3
LinkingTo: link2, link3"
With the space character, this is the compiler call found in 00install.out
g++ -I/usr/local/lib/R/include -I/usr/local/lib/R/include
-I/usr/local/include -I"/usr/local/lib/R/library/FLCore/include" -fpic
-g -O2 -c FLBRP.cpp -o FLBRP.o
while deleting it means both include folders are correctly added
g++ -I/usr/local/lib/R/include -I/usr/local/lib/R/include
-I/usr/local/include -I"/usr/local/lib/R/library/FLCore/include"
-I"/usr/local/lib/R/library/FLash/include" -fpic -g -O2 -c FLBRP.cpp
-o FLBRP.o
Secondly, this behaviour has been detected when running R CMD check on
Linux (R.Version below), while in windows the second include is never
generated even if the space character is deleted.
g++-sjlj -Ic:/progra~1/r/r-2.6.2/include
-I"c:/progra~1/r/r-2.6.2/library/FLCore/include" -O2 -Wall -c
FLBRP.cpp -o FLBRP.o
We haven't been able to test yet on the latest R 2.7.0rc.
Thanks,
Iago
