Issues with install of RSAP

[surya731]

Piers: I am trying to install RSAP on WIN7 64bit machine and having a really hard time. I am trying to follow the steps but it is having some issues. I installed devtools package and other dependencies like reshape and yaml. I also installed rtools.

I am pasting below some of output of the install. I tried from Rstudio as will as the R interface that came with the 3.2.4 install.

Can you help? Much appreciated in advance.

By the look of it it hasn't linked to the sapnwrfcsdk - you need to make sure that it is inC:/nwrfcsdk. You may also need to copy the C:/nwrfcsdk/lib DLLs into the system32 directory.

I don't use windows so I can't really give you much advice.

Cheers, Piers Harding.

Piers: Thank you for taking the time to answer this question. I tried all of that. I will keep trying and let you know. I will contact Basis friends who may be able to help with this.

I added to the PATH variable the directory where the dlls are. That did not help either. Thanks, Satish

Piers: I would imagine that windows users are using this package? Do you have information on this? Thanks, Satish

You may get some leads on the SDN forums if you look at how people are compiling other extensions like for sapnwrfc for Perl, Python and Ruby. You should also find the RSAP.dll that is compiled and use a dependency walker to determine whether or not all the necessary libraries are found on your windows system.

Cheers, Piers Harding.

Piers: Yes. I am doing all of these. I have not yet taken RSAP.dll through dependency walker but I will. Thank you. Satish

@surya731 This comment does not solve your problem, but FYI, some of us tried compiling RSAP on 64bit R and failed as well. It however works charmingly on Win 64bit and R 32bit installation.
