i follow the steps described in this site(http://ruby- gnome2.sourceforge.jp/hiki.cgi?tips\_rubyscript2exe) to create my standalone ruby app with gtk2 by using rubyscripts2exe. 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. C:/DOCUME~1/thom/eee/eee.main.exe.4/lib/rubygems/custom\_require.rb: line 32 Pango-WARNING \*\*:pango\_shape called with bad font, expect ugly output C:/DOCUME~1/thom/eee/eee.main.exe.4/lib/rubygems/custom\_require.rb: line 32 Pango-WARNING \*\*:pango\_font\_get\_glyph\_extents called with null font argument, expect ugly output C:/DOCUME~1/thom/eee/eee.main.exe.4/lib/rubygems/custom\_require.rb: line 32 Pango-WARNING \*\*:pango\_font\_get\_metrics called with null font argument, expect ugly output C:/DOCUME~1/thom/eee/eee.main.exe.4/lib/rubygems/custom\_require.rb: line 32 Pango-WARNING \*\*:\_pango\_cairo\_font\_install called with bad font, expect ugly output 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 !
