I deliberately avoided the FTBFS language, because it is not a FTBFS. It's different. It's like shipping a binary that cannot be regenerated and using that during build. The term FTBFS is well defined and does not cover this case. > If there is a serious DFSG issue here, it's not a FTBFS issue but > rather a question of whether or not the source package contains the > full source in the first place.

But I don't think it's a DFSG issue. Would you say the same if you compile a binary, use a hex editor to fix the binary and then ship the binary in your source package? I mean you preferred to edit the binary with a hex editor, so wouldn't it be preferred form for modification? Now consider my case. Most commonly, I want to change AC_RUN_IFELSE into AC_TRY_COMPILE or AC_COMPUTE_INT. That's a very simple change on configure.ac that produces a big diff on the generated configure. Also consider that autoconf projects tend to ship embedded copies of .m4 files. A bug in those .m4 files is often fixed upstream. Fixing it could be a simple matter of updating the embedded copy if one could regenerate configure. In both of these examples, I very much do not prefer working with the generated configure as it feels very much like editing a binary with a hex editor. Thus I argue that configure is not the preferred form for modification. Shipping only configure makes DFGS #3 practically moot. > If this has been discussed elsewhere or if there is Debian policy on > this I don't know about, I'd appreciate being pointed to this and I'm > happy to defer to this.

It is similar to the javascript bundling issue (where people suppose that minified or concatenated javascript files could be considered source). A very similar bu is #874261. #882538 could be called related. This issue comes about every time Debian is bootstrapped for a new architecture as configure tends to have bugs (e.g. ppc64el). I'm seeing it now as I bootstrap Debian for something like a new architecture (cross building). So this is the class of bugs to watch out. Helmut
