Compilation error with brms version 1.5.1

[atrolle]

Hello,

I downloaded "brms" from CRAN with all dependencies. I tried to run the following example, using "Kidney" dataset : library("brms") data("kidney")fit1 <- brm(formula = time | cens(censored) ~ age * sex + disease

• (1 + age|patient), data = kidney, family = lognormal(), prior = c(set_prior("normal(0,5)", class = "b"), set_prior("cauchy(0,2)", class = "sd"), set_prior("lkj(2)", class = "cor")), warmup = 1000, iter = 2000, chains = 4, control = list(adapt_delta = 0.95))

But I get the following error message : Compiling the C++ model Error in compileCode(f, code, language = language, verbose = verbose) : Compilation ERROR, function(s)/method(s) not created! file1748511132dd.cpp:8:39: fatal error: stan/model/model_header.hpp: No such file or directory

include <stan/model/model_header.hpp>

I use R 64 Bits version 3.3.2, RStudio version 1.0.136 and RTools version 3.4. RTools seems to work correctly :

Thread model: posix gcc version 4.9.3 (i686-posix-dwarf, Built by MinGW-W64 project)

My system PATH is as follows :

Sys.getenv("PATH") [1] "C:\R\R-3.3.2\bin\x64;c:\Rtools\bin;c:\Rtools\mingw_32\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\"

I do no see what's going wrong. Can anyone help me ?

Best regards, Arnaud.

Hmm, not sure what's going wrong. I would try to uninstall the rstan package, restart R and install rstan again (all in a fresh R session). If that doesn't help, I suggest you ask on the stan-users mailing list (https://groups.google.com/forum/#!forum/stan-users).

Thank you for the advice.

Best regards, Arnaud.
