Library sharing failure

Dear Rstan Communit,

Operating System: Linux
Interface Version: R v3.4.2
Output of writeLines(readLines(file.path(Sys.getenv(“HOME”), “.R/Makevars”))): No .R directoy
Output of devtools::session_info("rstan”): don’t (and can’t) have devtools.

I am trying to put some dev Rstan script in production on a massive cluster.
I compiled R (3.4.2) myself and installed all packages manually from tar.gz (no direct internet access).

During the installation of Rstan numerous warnings show up. All on the same pattern:
R-3.4.2/library/StanHeaders/include/src/stan/lang/ast/node/conditional_op.hpp:40:23: warning: non-static data member initializers only available with -std=c++11 or -std=gnu++11 [enabled by default]
bool has_var_ = false;

1/ Is this an issue that may explain or alter Rstan ?

2/ When I use the sampling function, I get this error:
Error in dyn.load(libLFile) :
unable to load shared object ‘/tmp/RtmpJA0O3Y/’: cannot open shared object file: No such file or directory

I tried to install R with “–enable-R-shlib=yes” but it fails.
3/ Is it a required flag for Rstan ?

Thanks for reading,

You need to compile with -std=c++11 in CXXFLAGS to get rid of that warning or just ignore it

It seems odd that you can start R and R be unable to open That seems like a problem with your setup, but you may be able to work around it by first doing


or whatever path is on for your server.

Under normal circumstances, no.

Thanks for your support.

If anyone is coming here with the same problem:
I recompiled R with the “–enable-R-shlib” flag and now Rstan works like a charm.
(Don’t be like me: don’t forget to use “make clean” before recompiling)

Unfortunatly, I can’t tell how I am not in “normal circumstances” :(

Thank you!

yes, I have the same issue :(

Was R compiled with or without the -enable-R-shlib flag?
