libopenraw 0.0.5 fails to build on 10.4.11: __Unwind_resume not found

[dbueno@…]

After sudo port -vvv install libopenraw, the symptom is:

/usr/bin/gcc-4.0 -O2 -Wextra -pedantic -g -Wall -o thumbc thumbc.o  -L/opt/local/var/macports/build/_opt_local_var_macport

Warning: the following items did not execute (for libopenraw): org.macports.activate org.macports.build org.macports.destr

I did a port sync an hour ago. I ran into this problem when trying to install the gimp port.

I'll attach the full build log in case it shows anything interesting.

This seems to be related to XCode and how it links C++ code. However, I just tried it on by 10.4.11 ppc and it built OK. I see some reports of this happening with XCode 2.2. What version of XCode are you using? I'm using 2.5.

I'm using XCode 2.5 on an Intel Mac (MacBook Pro).

Since I can't reproduce the failure here right now, I have disabled the building of the demo directory in r40857 and r40858. Hopefully, that will let you finish building the rest of the port while I try to figure out what is going on. Also have removed libopenraw as a dependency in gegl in r40856 as it is optional there.

So after things sync up (an hour or so from now), do

sudo port -d sync

and try again.

Please report back with your results either + or -.

Thanks -- I was able to build it.

You might try a

build.env   LD=g++

see if that links better...I had to do that for the MPlayer port ages ago, could be the same issue.

[devans@…]

Yes, perhaps. But why does it work for one person and not another?
