gtk2 build fails

[jxeon]

Seems like there are many knowledgable folks lurking here so enlighten me please I have tried so many things to resolve this-but I must be totally on the wrong track. mozilla, gnome all fail because I can't get gtk2 to compile-here's the shell output:
(Note: I'm running darwinports version from cvs prior to 1.0 release on a 1.33Mhz powerbook with panther 10.3.9)

Xft2 is installed-tried many suggestions from googling. A fink thread suggested that pango1-xft2-dev be installed (+ one other package ) but it's/they're not available from darwinports. I don't want to install fink.
Is there any hope for this?

[anaxamander]

Well, lets break it down. The problem your having is during the configure phase. So if we look in the configure script, we see (in this edited text):

if /opt/local/bin/pkg-config --exists 'pangoxft >= 1.2.0' ; then
if $have_freetype ; then
else
[blah, blah, you ain't got no freetype]
fi
else
{ { echo "$as_me:$LINENO: error: Xft Pango backend is required for x11 target" >&5
echo "$as_me: error: Xft Pango backend is required for x11 target" >&2;}
fi
-----------------------
If you run the command below, do you see yes on a separate line? If no, then you don't pango properly installed.:

pkg-config --exists 'pangoxft >= 1.2.0' && echo yes, I have pangoxft

-----------------------
You can reduce the configure logic to:

if PANGOXFT_test then
if FREETYPE_Test then (its implicit that the first line after an if statement is that the test was true)
(its true, I have freetype. Things are looking up)No output
(its false) echo "Xft Pango backend found but did not find freetype libraries"
end (of FREETYPE_Test if loop) - you passed the freetype_test
else (here is where we go if the PANGTOXFT test fails - its basically the same as the pkg-config command above
(PANGOXFT_test is false) echo THE ERROR YOU ARE SEEING: "Xft Pango backend is required for x11 target"
end if

It would seem that what is keeping you from gtk2 is a pangoxft problem. pangoxft comes from pango. I did an lsbom on my package:

./opt/local/lib/pkgconfig/pangoxft.pc 100644 501/80 337 849823468

I even removed that specific file, and sure enough I got zero output from the command above, which would mean that I (like you) would fail this particular test. I believe the fink pango-dev package contains ancillary headers, and this exact pkg-config file. Its stuff that is only useful for compiling software that rests on top of pango (like gtk2) - hence the "-dev" suffix. Darwinports doesn't do the "-dev" or "shlibs" stuff - it ALL gets installed.

[jxeon]

Thank you s-l-o-w-l-y I am learning. The code you provided returned simply the prompt.
That means pangoxft isn't installed-correct?
I don't know how to get pangoxft. I've been to the pango webpage...
I think you would recommend using fink to install pango? Problem is will it resolve this or just create other problems? I have some gnu packages ( binutils, primarily, hand installed in an attempt to get garnome to work )

[anaxamander]

Correct, pango (probably) isn't installed correctly. Or pkg-config isn't.

pangoxft is a part of pango. Its the "Xft backend". Try first to re-built it from scratch: "port clean pango" and then however you install, but tack a " -v" on at the end for verbose (like "port mpkg gtk2 -v").

In this case, you only need to be missing 1 file (the /opt/local/libs/pkgconfig/pangoxft.pc file) to wreck your whole day. I would look for it when it installs.

Fink does things differently. They split-off "-dev" and "-shlibs", but that isn't done in darwinports. "-dev" would mean headers and files useful only for compiling. and pkg-config is useful for compiling, so that is where the pangoxft.pc file would be - in a -dev package. In darwinports, its all unified - a stock build of pango will have that pkgconfig file (if you have pkgconfig installed and working - its all a big pyramid scheme).

Fink? FINK? I'm of the mind that fink IS a problem, but I'm a dp-lover, so I'm biased. glorified string-parser, THATs what fink is. Moaners, too. Yup, big whiners and moaners. Mostly moaners. yeah.

[jxeon]

Thank you once more anaxamander. I am focusing on this pangoxft problem before I get involved in the other (gcc) one. I looked at the man again for port, and read what it said about mpkg. Do you recommend this as the way to install pangoxft/gtk2? Is there an advantage to creating the mpkg? I have, so far, mostly used the install and build commands for installation.

[jxeon]

I must be missing something. The "port clean pango" didn't seem to have any effect. and when I do "port installed" pango is still listed and (active).
What didn't I do, or do correctly? Below is the shell output and doing "mpkg" gave the same result. I see that the check for xft is returning "no".

Here's what I did: I downloaded a bsd version of pango, untarred it and copied the pangoxft.pc file to /opt/local/lib/pkgconfig. OK no xft error BUT....
Now I get into the snag (below)-I went to the pango site but searching the error seems to bring up threads on a gtk bug and no clear solution. anyway heres the shell output once again:

I'm reading man ld but so far nothing. Thanks in advance for any help on this.

(Added later) I found this line: "ld: warning prebinding disabled because dependent library: /opt/local/lib/libpango-1.0.0.dylib is not prebound"
repeated many times in /Users/johnsmac/darwinports/dports/x11/gtk2/work/gtk+-2.6.7/config.log


And this: "ld: can't locate file for: -lcposix

[anaxamander]

how about:

sudo port clean pango
sudo port uninstall pango
sudo port install pango -v

--------------------------------
If push comes to shove, I know that 1.8.1 compiles fine, and port should compile pango if it sees a new one is available. Unless you have a localports directory, you'll have to alter the pango portfile for these changes:

version 1.8.1
checksums md5 88aa6bf1876766db6864f3b93577887c
post-destroot {
system "ln -fs libpango-1.0.0.800.1.dylib \
${destroot}${prefix}/lib/libpango.1.dylib"
system "ln -fs libpangox-1.0.0.800.1.dylib \
${destroot}${prefix}/lib/libpangox.1.dylib"
system "ln -fs libpangoft2-1.0.0.800.1.dylib \
${destroot}${prefix}/lib/libpangoft2.1.dylib"
----------------------------------
Do you have these files after you compiled? You can quickly see (without full paths) with "ls -R /opt/local/ | grep pango | grep ft"
./opt/local/include/pango-1.0/pango/pangoft2.h
./opt/local/include/pango-1.0/pango/pangoxft-render.h
./opt/local/include/pango-1.0/pango/pangoxft.h
./opt/local/lib/libpangoft2-1.0.0.800.1.dylib
./opt/local/lib/libpangoft2-1.0.0.dylib
./opt/local/lib/libpangoft2-1.0.dylib
./opt/local/lib/libpangoft2-1.0.la
./opt/local/lib/libpangoft2.1.dylib
./opt/local/lib/libpangoxft-1.0.0.800.1.dylib
./opt/local/lib/libpangoxft-1.0.0.dylib
./opt/local/lib/libpangoxft-1.0.dylib
./opt/local/lib/libpangoxft-1.0.la
./opt/local/lib/pkgconfig/pangoft2.pc
./opt/local/lib/pkgconfig/pangoxft.pc

If you see those files, then go onto gtk2.

and come to think of it, you probably have port images activated, so you should have that pkg-config file somewhere in like:
/opt/local/var/db/dports/software/pango/1.8.0/opt/local/lib/pkgconfig/pangoxft,pc

with a symlink to where its /opt location.

Wow is this the end of the pango-mango?
Gtk2 is building now.

I am very grateful-switching to version 1.8.1 (pango)
seems to have done it.
Is there documentation at darwinports or elsewhere for doing that? I didn't know I could edit the portfile and get a newer pkg. Anyway this pangoxft problem has been with me for months.
BTW I had done the make clean, uninstall and install with version 1.8.0 and still had that error-maybe it's an actual bug?
Thank you, thank you, thank you!!!

http://darwinports.opendarwin.org/docs/ch04s02.html is where you'll find how to make your own basic portfiles. It doesn't explicitly state that "to get a new version, change the version string and put in a new md5", but for a lot of packages, that is exactly what happens.
--------------
Your problem with pango could have been a bug, might have been a whacked out portfile/darwinportbase that existed for 1 day - the day you happened to download darwinports. For all I know, you might have also gotten out of that pango error by adding something like "revision 99" to the pango 1.8.0 portfile and saving it - that could have been the trick to a re-compile.
