The distcheck part of java.test on Solaris 2.6 fails with
| CLASSPATH=.:../.:$CLASSPATH javac -d . ../a.java b.java
| error: Can't read: b.java
| 1 error
| *** Error code 1
| make: Fatal error: Command failed for target `classdist_java.stamp'
| Current working directory
/tmp/build-sparc-sun-solaris2.6/tests/testSubDir/java-1.0/_build
| *** Error code 1
| make: Fatal error: Command failed for target `distcheck'
| FAIL: ../../automake-1.9a/tests/java.test
This is interesting and gives a clue to the issue:
$ make -n
| if test -n "a.java b.java"; then \
| echo 'CLASSPATH=.:../.:$CLASSPATH javac -d . ../a.java b.java' ; \
| CLASSPATH=.:../.:$CLASSPATH javac -d . \
| ../a.java b.java; \
| else :; fi
| echo timestamp > classdist_java.stamp
make forgets to add the directory for those elements of $? that are
not "plain words", i.e., separated by white space. Luckily, all those
issues have been fixed in Solaris 2.7 make and onwards.
However, IRIX 6.5 make doesn't prepend the VPATH directory part at all.
So, now I have two patches here: a hacky but efficient one that fixes
things for Solaris only, or a longer one that manually adds $(srcdir)
if deemed necessary.
What do you think?
Cheers,
Ralf
* lib/am/java.am (class%DIR%.stamp): Make sure `$?' is always
expanded as a "plain word", i.e., surrounded by white space,
so that Solaris 2.6 make correctly expands the VPATH directory
prefix.

the path of the prerequisite added; IRIX 6.5 make does not add
it, Solaris 2.6 make is inconsistent about adding it. Fixes
java.test failure.
