While attempting to compile gcj on my mster branch ( https://github.com/Zopolis4/gcj/tree/mster) , the compilation fails because several files within libjava are unable to include ffi.h because they cannot find it. In file included from ../../../../gcj/libjava/defineclass.cc:24: ../../../../gcj/libjava/include/java-interp.h:40:10: fatal error: ffi.h: No such file or directory 40 | #include <ffi.h> | ^~~~~~~ This is despite, as far as I can tell, the compilation of libffi being enabled as part of libjava in makefile.def.
