Hi, it took me a while to figure out why configure complained that I did not specify a host target type. Below are two bad approaches. In the first case below you can see there were two spaces in front of the '--enable-mpi' and that configure complained that econf did not provide --target, which it never does for me so (tested with coreutils package behaviour)) doubt in this particular case it is really necessary. The second is just an attempt to avoid two spaces in front of '--enable-mpi' (successfull, so do not look for the two spaces there) but the configure broke completely. Case 1: src_compile(){ local myconf="" if use mpi; then myconf="${myconf} --enable-mpi" fi if use threads; then myconf="${myconf} --enable-pthreads" fi econf "${myconf}" || die [cut] >>> Emerging (1 of 1) sci-biology/wcd-0.6.0 from science * wcd-0.6.0.tar.gz RMD160 SHA1 SHA256 size ;-) ...

Is there anything ebuild(1) or less preferably repoman(1) or other tool could do for me?
Created attachment 256829 [details] wcd-0.6.0.ebuild A testcase ebuild. Actually, in its fixed form but you can easily add the missing quotes to play with this.

(In reply to comment #0) > econf "${myconf}" || die This is incorrect. You are passing all the arguments as a single arg. You should not quote ${myconf}, or use an array.
I merely ;) understand but wonder: - why it breaks in the way so that configure claims no --target was specified, which is puzzling - I still think there could be a check that quotes are on an econf line But, as you wish. ;)
(In reply to comment #4) > I merely ;) understand but wonder: > - why it breaks in the way so that configure claims no --target was specified, > which is puzzling The call stack in the die message makes it obvious that there is a quoting problem in the econf call: * ERROR: sci-biology/wcd-0.6.0 failed: * econf failed * * Call stack: * ebuild.sh, line 56: Called src_compile * environment, line 2674: Called econf '--enable-mpi --enable-pthreads' > - I still think there could be a check that quotes are on an econf line Such a check is not necessary because the problem is easy to diagnose as said above.

Well, I am an ebuild-writing newbie so I really do not want to argue. Just wanted to give some feedback because it was tricky to me. Of course it takes a while until one learns how to interpret error messages. Will try to take care of it myself. ;-)
No, the key thing to notice is that '--enable-mpi --enable-pthreads' is invalid since you should never have more than one --foo-bar option inside a pair of quotes like that.
(In reply to comment #4) > - why it breaks in the way so that configure claims no --target was specified, > which is puzzling It doesn't claim it was not specified. It just notices unmatched arg, which way host was specified in the past. In other words, if you run configure like the following: $ ./configure i686-pc-linux-gnu You'll notice configure uses that and complains in the same way. The same is going to happen if you pass totally random, non-argument junk.
(In reply to comment #7) > No, the key thing to notice is that '--enable-mpi --enable-pthreads' is invalid > since you should never have more than one --foo-bar option inside a pair of > quotes like that. I see what you meant with the list previously ..., so what I would be thinking of doing is something about: if not isinstance(_myvar, list): if (isinstance(_myvar, stringtype) and not len(_myvar.split("'")) == 2): raise else: if len(_myvar) == 1 and "'" in _myvar[0]: raise It is not carefully coded and I see cases when it will break .. but I know I will not convince you anyway ... .;) But I got your points.

Yes, and that is where portage could pre-filter the input from the 'user', because configure is careless and just breaks e.g. --enable-mpi into just 'mpi' and one just dreams about some ugly magic behind breaking on `-' separators. And portage just allows me to exploit such bugs while it could be helpful. ;)
Seriously, it's jut not worth it to add code to try to detect these kinds of errors when they're easy enough to diagnose with a little experience.
it's similar to unpack "${A}" (which is wrong also)
