Setup default temporal directories for CCompilerDriver

Question

Problem: I have cyrylic symbols in my $UserBaseDirectory. As result temporal directory for CreateExecutableand friends is in my$UserBaseDirectory`. Which produce error.

Code:

Needs["CCompilerDriver`GenericCCompiler`"]

greeter = CreateExecutable[
  StringJoin["#include <stdio.h>\n", "int main(){\n", 
   "  printf(\"Hello MinGW-w64 world.\\n\");\n", "}\n"], "hiworld", 
  "Compiler" -> GenericCCompiler, 
  "CompilerInstallation" -> "C:/MinGW-64", 
  "CompilerName" -> "x86_64-w64-mingw32-gcc.exe"
  ]

produce error

CreateExecutable::cmperr: Compile error: x86_64-w64-mingw32-gcc.exe: error: C:\Users\¦Ð¦\[Not]¦¦¦¦TÁ¦-¦-¦+TÀ\AppData\Roaming\Mathematica\SystemFiles\LibraryResources\Windows-x86-64\Working-pc6807-6420-5640-3\hiworld.c: No such file or directory >>

but

Needs["CCompilerDriver`GenericCCompiler`"]
greeter = CreateExecutable[
  StringJoin["#include <stdio.h>\n", "int main(){\n", 
   "  printf(\"Hello MinGW-w64 world.\\n\");\n", "}\n"], "hiworld", 
  "Compiler" -> GenericCCompiler, 
  "CompilerInstallation" -> "C:/MinGW-64", 
  "CompilerName" -> "x86_64-w64-mingw32-gcc.exe",
  "WorkingDirectory"\[Rule]"c:\\1\\",
  "TargetDirectory"\[Rule]"c:\\2\\"
  ]

work fine.

Is there way to setup default value for "WorkingDirectory" and "TargetDirectory" for function like CreateExecutable?

It seems possible to use SetOptions for CreateExecutable as for other functions. Have you tried that?: SetOptions[CreateExecutable, "WorkingDirectory" -> "c:\\1\\", "TargetDirectory" -> "c:\\2\\"] — Mr.Wizard, Sep 18 '14 at 08:18
And you evaluated it after Needs["CCompilerDriver`GenericCCompiler`"]? — Mr.Wizard, Sep 18 '14 at 08:22
Okay, I don't know why that would fail, and I haven't set up a C compiler yet so I can't test this. I hope someone has a solution for you soon. — Mr.Wizard, Sep 18 '14 at 08:24

There is undocumented function which return working (temporary) and target

CCompilerDirectories[]
(*{C:\Users\Александр\AppData\Roaming\Mathematica\SystemFiles\LibraryResources\Windows-x86-64,C:\Users\Александр\AppData\Roaming\Mathematica\SystemFiles\LibraryResources\Windows-x86-64\Working}*)

DownValues of this function say that $CCompilerDefaultDirectory use for setup working and target directories

DownValues[CCompilerDirectories]
{HoldPattern[CCompilerDirectories[]]:>With[{CCompilerDriver`Private`target=$CCompilerDefaultDirectory},{CCompilerDriver`Private`target,FileNameJoin[{CCompilerDriver`Private`target,Working}]}]}

And then set $CCompilerDefaultDirectory as you wish.

PS: easier way is to studie documentation

$CCompilerDefaultDirectory returns the default location for creating output.

but we are not looking for easy ways =)
