New major version

[Pierre Labastie]

Tests for libjava fail with new version of dejagnu. from ​https://gcc.gnu.org/ml/java-patches/2016-q2/msg00007.html:

In DejaGnu 1.6, the utility procedure 'absolute' has been removed as
it can be implemented with Tcl's own 'file normalize' command...

The patch is:

===================================================================

     foreach x {. .. ../.. ../../..} {
     if {[file exists $d/$x/libtool]} then {
         # We have to run silently to avoid DejaGNU lossage.

I think we can use the sed:

sed -i 's/\[absolute/[file normalize/' libjava/testsuite/lib/libjava.exp

[bdubbs@…]

There is only one instance of 'absolute' in libjava.exp. We can just do:

sed -i 's/absolute/file normalize/' libjava/testsuite/lib/libjava.exp

omitting the '[' characters in the sed.

Right. I'll do that. I have another concern: there are 846 failures (about half the number of tests) in the libjava tests... Will try to investigate.

Also the compiled ecj binary does not run. It returns the error:

libgcj failure: gcj linkage error.
Incorrect library ABI version detected.  Aborting

I have tried to remove any remnant of the previous gcj version, but no joy. I wonder whether this version of gcj is viable.

It appears that gcc devs have abandoned java. They seem to have released a compiler suite with several regressions in their java stack. If they don't care about their java implementation anymore, neither should you. Just drop the gcc java stack or remain at an older gcc version for the java suite if you really need it.

[Pierre Labastie]

I've seen upstream have committed a bunch of fixes to the java suite after the release, so I'll try them.

I agree that the GCC java suite is of little use in BLFS, since we now have OpenJDK 1.8, and GCC cannot be used to build it (version 1.7 is needed, while GCC is version 1.5). The only other place I know where gcj is used is in some swig tests. If it is too hard to get a functional GCC java suite, I'll archive it.

the following sed is enough to fix the failures:

sed -i 's/major.*1000.*minor/major/' gcc/java/decl.c

See ​https://gcc.gnu.org/viewcvs/gcc/trunk/gcc/java/decl.c?r1=233218&r2=235546&pathrev=235575

I've just seen that there is an icedtea version to compile openjdk-8. See ​http://blog.fuseyism.com. I do not know whether it uses gcj.

Qt4 / its corresponding qtwebkit version have issues compiling. See #7787.

I have an *untested* workaround for Qt4, but none for Qtwebkit.
