I was unable to build cmdStan in 64-bit. Here is the error message:
c:\depot\cmdstan>make build uname: not found uname: not found g++ -I src -I stan/src -isystem stan/lib/stan_math/ -isystem stan/lib/stan_math/lib/eigen_3.3.3 -isystem stan/lib/stan_math/lib/boost_1.62.0 -isystem stan/lib/stan_math/lib/cvodes_2.9.0/include -Wall -DEIGEN_NO_DEBUG -DBOOST_RESULT_OF_USE_TR1 -DBOOST_NO_DECLTYPE -DBOOST_DISABLE_ASSERTS -DFUSION_MAX_VECTOR_SIZE=12 -DNO_FPRINTF_OUTPUT -pipe -m64 -Wno-unused-function -Wno-uninitialized -Wno-unused-but-set-variable -c -O3 -o bin/cmdstan/stanc.o src/cmdstan/stanc.cpp Assembler messages: src/cmdstan/stanc.cpp:1:0: sorry, unimplemented: 64-bit mode not compiled in #include <stan/command/stanc_helper.hpp> ^ Fatal error: no compiled in support for x86_64 make: *** [bin/cmdstan/stanc.o] Error 1
To overcome this, I changed to “BIT=32” in make/os_win. This seemed to work okay.
If this issue known about? If so, perhaps BIT can be set to 32 in os_win by default, until fixed. It stumped me for a bit, until I read more of the documentation.
Operating System: Windows 10
Interface Version: cmdStan 2.15
Compiler/Toolkit: make, g++, via RTools
