[Bug libgcj/31891] New: Libjava configuration scripts out of sync for pkg-config tests

[rob1weld at aol dot com]

This same problem also occurs on i686-pc-cygwin, it likely would occur on all
platforms.


The ./configure scripts "gcc-4_2-branch/libjava/configure" and
"gcc-4_2-branch/libjava/classpath/configure" are out of sync.


During "make" I get this message:

checking for pkg-config... /usr/bin/pkg-config
checking for gtk+-2.0 >= 2.4... yes
checking GTK_CFLAGS... -DXTHREADS -DXUSE_MTSAFE_API -I/usr/include/gtk-2.0

-I/usr/include/pango-1.0 -I/usr/include/freetype2 -I/usr/include/glib-2.0
-I/usr/lib/glib-2.0/include

-lglib-2.0 -lintl -liconv
checking for glib-2.0 >= 2.4 gthread-2.0 >= 2.4... yes


Then later I get this message (for classpath directory's configure):

checking for gtk+-2.0 >= 2.8 gthread-2.0 >= 2.2 gdk-pixbuf-2.0... Requested
'gtk+-2.0 >= 2.8' but version of GTK+ is 2.6.10
configure: error: Library requirements (gtk+-2.0 >= 2.8 gthread-2.0 >= 2.2
gdk-pixbuf-2.0) not met; consider adjusting the PKG_CONFIG_PATH environment
variable if your libraries are in a nonstandard prefix so pkg-config can find
them.
configure: error: /bin/sh
'/cygdrive/C/makecygwin/gcc-4_2-branch/libjava/classpath/configure' failed for
classpath
make[1]: *** [configure-target-libjava] Error 1


So I fix that, type "make", then this happens:

make[3]: Leaving directory
`/cygdrive/c/gcc-4_2-branch-build/i686-pc-cygwin/libjava'
Making all in libltdl
/bin/sh: line 17: cd: libltdl: No such file or directory
make[2]: *** [all-recursive] Error 1


I deleted /cygdrive/c/gcc-4_2-branch-build/i686-pc-cygwin/libjava, to get
configure to retry. (Note: Later I found out that I could simply create the
missing directory and type "make" again.)


My complaint is that the first message is "checking for gtk+-2.0 >= 2.4...
yes", then sometime later it wants 2.8. When that is fixed ./configure doesn't
know what to do about the missing libltdl directory. The _first_ configure
script should check for 2.8 (if a _later_ script requires that version) and it
should work through the missing directory issue correctly. 


The scripts in Cygwin's gcc, configure uses a more thorough method for testing
gtk. This is from the /cygdrive/c/cygwin/usr/src/gcc-3.4.4/libjava/configure
script (obtained by downloading source from cygwin.com using setup.exe). Here
is a modified snippet from config.log:

The "old" method was to create a program and make a call to the library to get
it to tell you it's version. The "modern" way is to use pkg-config (which
usually requires you to get the xyz-DEVEL-version just to get the .pc file).

Note that the above code is not perfect. First it tests "!=" and if true,
fails. It does not get to the test further on that checks ">". The code (as
written) requires that the version of the headers match the version of the
.dlls, but the (windows) gtk site
(http://www.gimp.org/~tml/gimp/win32/downloads.html) says it is OK to use old
headers and new .dlls. 

It _might_ be OK to change the test to allow older headers with the newer .dlls
for _some_ versions (no doubt there are versions of each that this would not
work - it is easier not to check a compatability list but leads to more work to
install dev libs).


A good place to get gtk for Cygwin (ready to roll) is from:

GTK+ and The GIMP installers for Windows
http://sourceforge.net/project/showfiles.php?group_id=121075


First install the Cygwin setup.exe Gtk (and other needed files), then install
the sourceforge version using directory c:\cygwin\gtk\2.0\ (instead of the
installer program's default).


Next, alter your C:\cygwin\lib\pkgconfig\gtk+-2.0.pc file and fix these two
lines like this:

libdir=/gtk/2.0/bin/
Version: 2.10.11


(You might also need to impgen the .dll files.)

Java seems to be configuring fine (for Cygwin) and compiling without error.


For Linux I used a non-stable gtk (and all the other gtk dependancies) obtained
with Aptitude (and a LOT of dependancy tweaking). Evrything _IS_ compiling and
testing very well under Linux (for the JAVA portion of gcc).
