I understand that macros are first expanded, and thus, if they expand to a legal construct, i.e. "filename" or <filename>, then the compiler will accept them. Now here are your statements in a rephrased form - correct me if I'm wrong 1) items like FT_FREETYPE_H, i.e. items without the encapsulating '"' or '<', '>' are meant to be macros; 2) the above macros used to be defined in freetype/config/ftheader.h freetype/internal/internal.h files; 3) the above .h files are not within the source tarball anymore - here is my check of this statement: " [31] 0:19 sergei@xxxxxxxxxxxxx:/mnt/removable4/sergei/build_work/build> find fontconfig-2.3.2 -name "*.h" fontconfig-2.3.2/src/fcint.h fontconfig-2.3.2/fontconfig/fontconfig.h fontconfig-2.3.2/fontconfig/fcfreetype.h fontconfig-2.3.2/fontconfig/fcprivate.h fontconfig-2.3.2/fc-case/fccase.h fontconfig-2.3.2/fc-case/fccase.tmpl.h fontconfig-2.3.2/fc-lang/fclang.h fontconfig-2.3.2/fc-lang/fclang.tmpl.h fontconfig-2.3.2/fc-glyphname/fcglyphname.h fontconfig-2.3.2/fc-glyphname/fcglyphname.tmpl.h [32] 1:06 sergei@xxxxxxxxxxxxx:/mnt/removable4/sergei/build_work/build> " - indeed they are not in the tarball. Now, taking your statement: " When a FT_* macro is undefined none of the cases 1.-3. occurs, the preprocessor sees literal #include FT_INTERNAL_OBJECTS_H and complains. Thus you get errors on lines correspoding to inclusion of internal headers (through FT_INTERNAL_* macros). " may I rephrase it this way: fontconfig-2.3.2.tar.gz can NOT be compiled because some header files (namely freetype/config/ftheader.h, freetype/internal/internal.h) are missing in it ? If so, is my earlier statement, that fontconfig released a tarball which can not be compiled, correct ? Thanks, Sergei.
