I decided to install wine today, so I downloaded the latest tarball (20020605), and compiled it. However, I got this error message. I can't exactly what, but it was something like: make: no rule to make target poppack. , needed by spec32 I found a header file called poppack.h, and the makefile (tools/winebuild/Makefile) and where it was mentioned (line 396): spec32.o: ./spec32.c ../../include/config.h ../../include/wine/port.h \ ../../include/winbase.h ../../include/basetsd.h \ ../../include/windef.h ../../include/winnt.h ../../include/pshpack2.h \ ../../include/poppack. ../../include/pshpack4.h \ ../../include/guiddef.h ../../include/winerror.h \ ../../include/wine/exception.h ./build.h I changed poppack. to poppack.h , and it compiled without errors. Not exactly a huge problem, I suppose most people could have figured it out, but I thought you should know.
