[Php-java-bridge-users] compiling on debian/gcc4 transition

[Peter N. <pn...@kr...>]

Hi there,

as some of you might know debian is moving the testing/unstable
distribution to a new default compiler(gcc 3.x -> gcc 4).

So far compiling the bridge has always been a pleasure. ;) Yesterday I
updated to gcc 4. Now the bridge complains:

configure: WARNING: YOUR GCC INSTALLATION IS BROKEN. It tries to link
with the same library for -m32 and -m64 builds. This may result in a
"wrong ELF class" error at runtime. Although you can work around this
bug at runtime by changing the LD_LIBRARY_PATH, we recommend to
re-install the gcc compiler before youcontinue to install the PHP/Java
Bridge.

I think it should be possible to set the compiler-version via EXPORT
CC=gcc-3.3 but this seems not to work, probably becaus CC is set to gcc
in the Makefile.

I know this is most likely my fault or a problem with debian, still I
would appreciate if anyone of you got a hint to solve this.

Thx,
Peter

Yes, I am a fool. :-<
Makefile is created by autoconf/configure whatsoever and of course
reflects the the CC,CXX environment vars I do set.

Still I think I haven't noticed this before:

----------snapp------------------

Everything seems to work now using gcc3-3 and g++-3.3 as the
libs(java,php5) are all compiled with gcc-3.x. Don't know if it would
work with gcc-4.0.

Since I use the 'make CFLAGS="-m32"' now probably I shouldn't have any
problems but still I'd like to know about that message, which sounds
somewhat scaring to me.

Cheers,
Peter

Hi Peter,

Well, your GCC installation uses two different static
libraries for m32/64 but only one dynamic library. 
Depending on the processor architecture this may or
may not be a problem.  I have changed the message in
2.0.8RC5.

gcc4 should be able to compile the source. (other
distributions such as RedHat use gcc4 for a long time
now, so I don't think that this is an issue).
