Difficulties with isfinite() on Windows machines

[cschwarz-stat-sfu-ca]

Description:

Using the isfinite() function in TMB cases compiler error on Windows but not on Macintosh when using compile() in R

Reproducible Steps:

Here is my simple.cpp file>

---

#include <TMB.hpp>

template
Type objective_function::operator() ()
{

DATA_VECTOR( left ); // left and right values
PARAMETER( log_shape );

Type test;
Type test2;

test = pow(left(1)-log_shape,2);

test2 = isfinite(test);

ADREPORT (test);
REPORT(test);
return test2;
};

Here is my R code

library(TMB)
compile( "simple.cpp" ) # compile() is a function within the TMB library

dyn.load(dynlib("simple"))

simple.model <- MakeADFun(
data= list(left=10.1),
parameters=list(log_shape=3.1 ),
DLL="simple"
)

simple.model$fn(simple.model$par)

Current Output:

When running the R code on Macintosh

library(TMB)
compile( "simple.cpp" ) # compile() is a function within the TMB library
Note: Using Makevars in /Users/cschwarz/.R/Makevars
clang++ -I"/Library/Frameworks/R.framework/Resources/include" -DNDEBUG -I"/Users/cschwarz/Rlibs/TMB/include" -I"/Users/cschwarz/Rlibs/RcppEigen/include" -DTMB_SAFEBOUNDS -DLIB_UNLOAD=R_unload_simple -DTMB_LIB_INIT=R_init_simple -I/usr/local/include -fPIC -Wall -g -O2 -c simple.cpp -o simple.o
....
clang++ -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress -L/Library/Frameworks/R.framework/Resources/lib -L/usr/local/lib -o simple.so simple.o -F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework -Wl,CoreFoundation
[1] 0

i.e. a successful compilation

When running the R code on Windows it terminates with
C:/Rlibs/RCPPEI1/include/Eigen/src/Core/CoreEvaluators.h:960:8: warning: ignoring attributes on template argument 'Eigen::internal::packet_traits::type' {aka '__vector(2) double'} [-Wignored-attributes]
enum {
^
make: *** [C:/PROGRA1/R/R-41~1.0/etc/x64/Makeconf:245: simple.o] Error 1
Error in compile("simple.cpp") : Compilation failed

If you comment out the isfinite() statement it compiles fine.

TMB Version:

Mac: > packageVersion("TMB")
[1] ‘1.7.20’

Windows

packageVersion("TMB")
[1] ‘1.7.20’

R Version:

Mac: "R version 4.0.5 (2021-03-31)"

Windows: "R version 4.1.0 (2021-05-18)"

Operating System:

Mac: OS 11.3.1

Windows: Windows 8.1 Pro

I'm afraid that you've lost me... I'm a Mac user and have seldom used C++ (except to write TMB functions). I don't have a Makevars file (that I'm aware of), nor do I know how to set C++ compiler options in this make file. Can you point me in the right direction? Can I specify this using the flags= parameter of the TMB::compile() function? For example, I ran

library(TMB) compile( "simple.cpp", flags="-std=c++11") # compile() is a function

within the TMB library and it looks like the std=c++11 in the output below appears to be set (i'm assuming that if it appears twice in the call, it overrides the gnu++11 call?? "C:/rtools40/mingw64/bin/"g++ -std=gnu++11 -I"C:/PROGRA~1/R/R-41~1.0/include" -DNDEBUG -I"C:/Rlibs/TMB/include" -I"C:/Rlibs/RCPPEI~1/include" -DTMB_SAFEBOUNDS -DLIB_UNLOAD=R_unload_simple -DTMB_LIB_INIT=R_init_simple -std=c++11 -c simple.cpp -o simple.o In file included from C:/Rlibs/RCPPEI~1/include/Eigen/Core:397, from C:/Rlibs/RCPPEI~1/include/Eigen/Dense:1, from C:/Rlibs/TMB/include/TMB.hpp:53, from simple.cpp:1: but this leads to the same compilation error .... double'} [-Wignored-attributes] enum { ^ make: *** [C:/PROGRA~1/R/R-41~1.0/etc/x64/Makeconf:245: simple.o] Error 1 Error in compile("simple.cpp", flags = "-std=c++11") : Compilation failed Thanks Carl

My guess is that isfinite() is a c++11 function (see https://eigen.tuxfamily.org/dox/group__CoeffwiseMathFunctions.html). I know that with clang++, c++11 is enabled by default but I am not sure about windows distribution of gcc 8.2.0. — You are receiving this because you authored the thread.
