[ECOS] Re: Wrong character set in Cofiguration Tool

[Uwe Kindler]

Hi Fabian,

I have no solution for this problem but I can confirm that it also 
exists on Windows 7. The problem occures for warnings and errors. Here 
is an example of console output with warnings:

cc1: warning: command line option ‘-Woverloaded-virtual’ is valid 
for C++/ObjC++ but not for C [enabled by default]
cc1: warning: command line option ‘-fno-rtti’ is valid for 
C++/ObjC++ but not for C [enabled by default]

Hi

That is just the quotes in UTF-8. Two examples below are true for Linux
and I hope this true for Cygwin environment too.

For LANG=en_US.utf8 and if terminal supports UNICODE you have to see

  % echo 'main(){return 0;}'>a.c
  % cc -Wall a.c
  a.c:1: warning: return type defaults to ‘int’

For standard "C" locale and for *any* terminal we see only ASCII (no
potential mess)

  % LC_ALL=C cc -Wall a.c
  a.c:1: warning: return type defaults to 'int'

If you set LANG variable properly and your terminal supports Unicode
then you have to see normal quotes, otherwise you will see some garbage
in output. So, try either to fix LANG variable or just use standard "C"
locale: append a line 'export LC_ALL=C' in your ~/.bashrc and re-login.

I do not sure about UTF-8 in Cygwin environment, but I hope LC_ALL=C
has to help.

Hi,
Sergei you're right that's the problem and also the solution! For me it worked to set an environment variable called "LC_ALL" and set the value to "C"! I did that in windows but I think the result using the cygwin bash is the same!


Regards Fabian
