Comment (by vaccari@…):

 So, I'm now trying to produce the preprocessed code for
 macho_relocatable_file.cpp

 Found it in

 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_devel_ld64/ld64/work/ld64-133.3/src/ld/parsers
 }}}

 cd there and tried

 {{{
 sudo clang -E -I. -I../../ld -I../../abstraction
 macho_relocatable_file.cpp -o macho_relocatable_file.cpp.preprocessed
 }}}

 But got error


 {{{
 In file included from macho_relocatable_file.cpp:35:
 ../../abstraction/MachOFileAbstraction.hpp:290:10: fatal error:
       'mach-o/arm/reloc.h' file not found
 #include <mach-o/arm/reloc.h>
 }}}

 I can only guess some needed configuration is missing when trying ''clang
 -E'' straight from the command line.

 I'm willing to help here, but don't want to waste your time either, given
 I'm quite ignorant on this matter...
