[Bug java/35923] New: gcj: error trying to exec 'ecj1': execvp: No such file or directory

[david dot griffiths at gmail dot com]

I get the following error on a clean 4.3.0 build when trying (eg) "gcj
foo.java":

gcj: error trying to exec 'ecj1': execvp: No such file or directory

I'm a bit puzzled by bug 32712 being listed as resolved and even more so by the
references to just needing to run "./contrib/download_ecj". I tried this (on a
clean installation) and it made no difference. I also tried specifying the
location of ecj.jar with:

 ./configure --with-ecj-jar=/home/dgriff/gcc-4.3.0/ecj.jar

again, that made no difference.

Run the command with -v to show what it's trying to exec, and paste the
output as well as the actual location of ecj1.

Well there is no ecj1 - that's the problem I think. It didn't build it.
Presumably nobody has noticed this before because they are picking up an old
version of ecj1? Anyway, here's the -v output:

ecj1 is just a wrapper script that runs ecj.jar to generate the
bytecode, see <http://gcc.gnu.org/ml/java/2008-04/msg00006.html>.

> Configured with: ./configure

Not good.  Try building in an empty dir outside of the source dir as the
install directions state and see if that fixes the problem.

Hi, made no difference. I created a separate gcc-4.3.0-build directory and
placed the ecj.jar both in there and in the top level source director (just to
be sure).

Note that the build directory contains no libjava on completion, not sure if it
should? (As that's the only place that seems to refer to ecj1). I am just doing
"./configure" but that should build java by default, right? The config.log
certainly contains lines like "build_configargs='--cache-file=../config.cache
'--enable-languages=c,c++,fortran,java,objc'
--program-transform-name='s,y,y,''".

Oh, this is Cygwin.  Ick.  gcj support for Cygwin is very iffy.  Last
time I tried you had to --enable-libjava to get it to build libjava as
it was disabled by default.  And even then it will only build a static
libjava which is not very useful.  Also the default SJLJ EH makes
performance nearly intolerable, so you'll probably want to switch to
Dwarf-2 EH.  I'm not sure if all the required patches for DW2 EH to 
function correctly on MinGW/Cygwin are in the FSF tree or not.  (Along
with the other problems with DW2 EH on Win32...)

If you google a little I think you can find hacks for building a MinGW
shared libjava which you might be able to adapt, but I don't know.  I
wouldn't expect much.

4.3.3 on Linux has the same problem.

Target Milestone: 4.3.3?

------- Comment #10 from davek at gcc dot gnu dot org  2010-02-17 15:24 -------
This bug was originally caused by the fact that libjava was disabled in
noconfigdirs for cygwin at the time the report was filed.  This has long since
been fixed.

The last four comments are incorrect in assuming that they have the same bug. 
Same error message != same bug; libjava is enabled in configdir on those
targets.  If those reporters are still having problems, they should open
separate reports and give full details there.
