After running for a 10 minutes, the tool reported:

cheched headers: 18/18 (100%) )
warning: compilation errors in following headers:
QtCore QtOpenGL QtXml QtNetwork QtXmlPatterns QtAssistant QtHelp QtWebKit 
QtTest QtDBus QtScript QtSql QtGui QtScriptTools QtUiTools QtDesigner QtSvg 
Qt3Support

(I think you meant "checked headers", please run a spell checker in your 
tools)

So 18 out of 18 headers failed to compile. Here's why:

$ head -n3 header_compile_errors/Qt/errors_v1
cc_tmp/Qt1.h:1:46: error: /* This section is not necessary */: Arquivo ou 
diretório não encontrado
cc_tmp/Qt1.h:2:85: error: /* For example, it is a tree.h for libxml2 and 
ft2build.h for freetype2 */: Arquivo ou diretório não encontrado
cc_tmp/Qt1.h:3:67: error: /* This section is useless when -fast option 
selected */: Arquivo ou diretório não encontrado

So apparently I cannot leave the comments in the sections of the descriptor 
file. Since the descriptor example the tool generates leaves them, it's 
misleading. Please fix that.

And why didn't it bail out after the first one failed to compile? I didn't have 
to wait 10 minutes to find out that the process would fail.

Also, the tool could say that the results are in the subdirectory.

After fixing all those errors, the tool ran for 12 minutes and generated the 
empty report attached. I've also attached the two descriptor files.

What did I do wrong? I doubt that it needed 12 minutes to generate a listing 
of files I had given it as input.
