gfortran mingw64 error

[s1park]

Hello,
I'm having trouble reading in a model using mrgsolve. I'm not sure how to troubleshoot the error but it may be how my system is running the program. I've attached a part of the error message and was wondering if there's a solution.

Hi @s1park -

It's been a while since we had to straighten out Windows toolchain. But looks to me like possibly there are several tool chains installed and they aren't playing nice together.

Rather than posting the screenshot, can you run the code with this recover = TRUE argument and send me the output?

library(mrgsolve)

mod <- mcode("foo", foo, recover = TRUE) ## <---- try to load your model, but pass recover = true

# Then save the output object to a file and post that
dput(x = mod, file = "mod.dput")

Thanks,
Kyle

Thanks, Kyle. See the attached output object.
mod.dput.txt

Thanks, @s1park ; first time I used that to help someone debug and seems to have worked great.

So it looks like there is a gfortran compiler that might be supporting nonmem install that is working its way into the build path for your model. Something quick and dirty to try is to rename that folder temporarily and see if R finds another gfortran compiler hopefully the one that ships with rtools43.

Let me know what happens.
