Description Enrico Weigelt 2006-07-26 02:54:08 UTC

Maybe the old issue w/ exports depending on features ;-o

Here's what someoen reported to me lately:

wonderin' if you could send me the version you compiled. Do you think that will
work for me+if I simply replace the original with your file?

Comment 1 Enrico Weigelt 2006-07-26 02:55:14 UTC

ugh, this bugzilla is probably too old for mail-style quoting ?

Comment 2 Daniel Stone 2006-07-26 07:21:47 UTC

--enable-fc

Comment 3 Enrico Weigelt 2006-07-26 09:31:48 UTC

You simply ignored the issue and simply reject evrything that doesnt taste you
(just as we're used to know you) !

The problem is that the API interface (not just ABI) massively changes if you
turn off fc - many symbols are simply missing. Many applications break, although
they have sucessively imported libXfont.

Changing export interfaces on feature switches are making big headaches to lots
of people.

At least there should be an separate .pc file generated when

Comment 4 Adam Jackson 2006-10-12 18:26:00 UTC

Why yes, if you disable options at configure time, you can change ABI.  Shocking.

The options here are to remove the configure option so people don't shoot
themselves with it, or to add some new header for libXfont containing #defines
for the built configuration.

Comment 5 Daniel Stone 2007-02-27 01:33:00 UTC

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

There should at least be an notice in the option description. 
And if the option is enabled, an additional .pc file should be created.

Comment 7 Adam Jackson 2008-02-24 22:00:13 UTC

The fpe discovery we're doing now is crap.  We ought to inspect libXfont at runtime.

Comment 8 Jeremy Huddleston Sequoia 2011-10-03 00:33:39 UTC

I think this is no longer an issue with changes made in this area about 1-2 
years ago.  Please reopen if I am incorrect.
