Hi,
I am currently preparing a package for hdf5 that ships and compiles from
source on windows. The intention here is to avoid having to ship or
download a binary from an unknown source. As a dependency, I need the cmake
program installed.
Here my question:
1. Is cmake installed on win-builder? If not, could it be installed? If
yes, in a specified standard location or available through the PATH
variable?
It is not. I could do that if you tell me which version I need.
2. How do I specify that a package is only intended for a specific OS?
See WRE, in the DESCRIPTION file you can specify:
OS_type: unix
would make it non-Windows and vice versa.
On another note here:
The package I am preparing would only compile the binaries on windows. On
other systems, I would prefer to have people install them thought native
services (e.g. apt-get) to make configuration etc. more manageable for
system administrators (even though that puts a little more burden on the
end-user on these systems).
Be careful to get licenses and copyright information right if you
include thirs party sources.
Second question:
Is there a way to specify an OS-specific dependency? As the hdf5lib package
is rather large and intended for windows only, I would prefer if it isn't
downloaded anywhere else.
You can only have one version of the package sources on CRAN.
Best,
Uwe Ligges
thanks for your help
Holger
