[R-pkg-devel] "Setting LC_CTYPE=en_US.UTF-8" failed and "qpdf28.dll was not found" on Win 10

[Spencer Graves]

Hello:


	  I'm getting different errors with MINGW64 and "Git CMD" under Windows 
10 for "R CMD check sos_2.1-4.tar.gz" for the current version on 
GitHub.[1] I think it will run with Winbuilder, but I'd like to be able 
to use the Windows 10 computer I have.


	  Specifically, under MINGW64, I get the following:


* checking DESCRIPTION meta-information ... WARNING
During startup - Warning message:
Setting LC_CTYPE=en_US.UTF-8 failed
  ERROR


	  Under Git CMD, I get a different error:  I get popups labeled 
"qpdf.exe - System Error" saying, "The code execution cannot proceed 
because libgcc_w_dw2-1.dll was not found.  Reinstalling the program may 
fix this problem." I click "OK" and get essentially the same message for 
libstdc++-6.dll and then for qpdf28.dll.


	  Suggestions?
	  Thanks,
	  Spencer Graves
