i follow the steps described in this  
site([http://ruby-gnome2.sourceforge.jp/hiki.cgi?tips\_rubyscript2exe](http://ruby-gnome2.sourceforge.jp/hiki.cgi?tips_rubyscript2exe)) to  
create my standalone ruby app with gtk2.  
and this exe file does run well except all the characters display in  
question mark . i got these error messages:

D:\My Documents\My work\Ruby\factory\>main.exe \>\>1.log  
C:/DOCUME~1/thom/eee/eee.main.exe.4/lib/rubygems/custom\_require.rb: line  
32  
Pango-WARNING \*\*:No builtin or dynamically  
loaded modules were found. Pango will not work correctly.  
This probably means there was an error in the creation of:  
‘C:\DOCUME~1\thom\eee\eee.main.exe.4\etc\pango\pango.modules’  
You should create this file by running pango-querymodules.

i don’t know what’s the problem about it. i can run my app using command  
“ruby myapp.rb”, and everything is ok.  
thanks for your help !

Hi,

You need to call the 3 programs below before starting GTK2 application.

GTK\bin\pango-querymodules.exe \> …\etc\pango\pango.modules  
GTK\bin\gdk-pixbuf-query-loaders.exe \> …\etc\gtk-2.0\gdk-pixbuf.loaders  
GTK\bin\gtk-query-immodules-2.0.exe \> …\etc\gtk-2.0\gtk.immodules

Your error say the pango.modules have’t been created yet.

HTH,
