Further issues when building CUETools on a case sensitive filesystem or
folder were found in CUETools.Codecs.TTA and ttalib-1.1
- Remove precompiled headers from:
CUETools.Codecs.TTA.vcxproj
TTALib.vcxproj
This fixes case sensitivity issues coming from different spellings of
stdafx (stdafx.cpp, Stdafx.cpp; stdafx.h, Stdafx.h). The stdafx.h
header files were empty in both cases, so remove precompiled headers
completely.
Remark: The file TTALib.vcproj was unused and therefore removed.
TTALib.vcxproj is used by CUETools and gets updated.
- Use lowercase ttalib-1.1 for includes in CUETools.Codecs.TTA.cpp,
because the name of the sub-directory, which contains the TTALib
files is lowercase:
TTALib-1.1->ttalib-1.1
- Fix lower/uppercase spelling of included headers in files of
ttalib-1.1 according to the spelling of the filenames:
bitreader.h->BitReader.h
ttareader.h->TTAReader.h
ttawriter.h->TTAWriter.h
Rename the file ttacommon.h for conformity and update the includes:
ttacommon.h->TTACommon.h
- Summary of changes to files (rename, delete):
deleted: CUETools.Codecs.TTA/Stdafx.cpp
deleted: CUETools.Codecs.TTA/Stdafx.h
deleted: ttalib-1.1/Stdafx.cpp
deleted: ttalib-1.1/Stdafx.h
renamed: ttalib-1.1/ttacommon.h -> ttalib-1.1/TTACommon.h
deleted: ttalib-1.1/TTALib.vcproj
