There's another possibility; it is superfluous :)
Unfortunately, we're not on the same page.
We're professionals, not interested in personal arguments.
So let's technically meet on the same page, yours, mine or
anybody else's for that matter.
MY page ------------------------------------------------------------->:
NOTE:
please read it carefully, and try to UNDERSTAND _exactly_
what I've been claiming - even if you DISAGREE.
All is based on _my_ tests, experience. Your (or somebody
else's) mileage may vary.
BTW, as far as it goes, our mileage is in sync so far.
1. Firefox does NOT compile with --with-system-png ON.
Period.
BTW, this is the only thing I've been forcefully and clearly
saying from the very beginning. Period.
The notion "enable" was introduced by you later, as if by
misreading my word "with".
2. --enable-system-png is NOT equivalent to --with-system-png.
At the very least it is not documented in './configure --help'.
IMHO, it DON'T matter if one uses it or not.
Period.
NOTE:
Yes, I know, people claim here and there that "with = enable"
but this is what _Firefox-4.0_ configure has to say on this:
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
configure then goes on to SPECIFICALLY list which you can use with
"with" and which you can use with "enable":
--enable and --with options recognized:
[excerpts, as examples:]
...
--enable-valgrind
...
...
--with-system-libxul
...
2.1. NO mention of _png_ in configure at all, which _tends_
to confirm that the use of "with-system-png" is NOT recognized
(and thus wrong - as I've been saying and experiencing all along)
3. FWIW, _my_
ldd /usr/lib/firefox-4.0/firefox-bin | grep libpng15.so.15
libpng15.so.15 => /usr/X11R6/lib/libpng15.so.15 (0xb599f000)
To repeat:
The above was taken after a successful build/install NOT using either
--with
NOR
--enable
4. Please, take the time and do a test where you do NOT use your
--enable
NOR obviously
--with (my claim)
This will, hopefully settle the matter.
Then, do an 'ldd' and see if it differs in any way (on png)
from the one you just posted.
BTW, you don't have to post the results if you don't feel like :)
