I hate when I see that The specified module could not be found error because it means stupid Windows is not able to tell the name of the module that could not be found. Normally it’s a dependency problem, and from GMT in this case. I’m assuming you installed GMT6 from its Windows installer, right? What does this print?
run(`gmt --version`)
also, does this command run from Win cmd (NOT the Julia REPL) show a red circle, or complains with same gmt_w64 error?
echo 1 1 | gmt plot -Ba -Sc0.5 -Gred -png map
But better that you open an issue in GMT.jl where we can continue this talk.
Yes GMT.jl is the github site (but GMT is also in github).
The fact that it worked on the cmd is even more confusing because it uses exactly the same binaries. The Julia REPL error is for sure due to a copy paste change of characters. It needs to be back-ticks. This is what I get (but note that I’m using GMT master version)
