MacPorts icu compile

[blarghenha]

What's the best way to fix:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/libxml2.py", line 1, in <module>
    import libxml2mod
ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/libxml2mod.so, 2): Symbol not found: ___divmoddi4
  Referenced from: /opt/local/lib/libicui18n.67.dylib

when building macports icu on Tiger?

My current solution is to set:

configure.optflags -O0

in the Portfile and I wonder if there is a better way to prevent this optimization.

Hm, the actual version of libxml2 is 2.9.5. Why don’t you install the latest version? That probably solves the error. Which version do you have installed?

EDIT: corrected fact missing assumption.

Yeah, the problem isn't libxml2. When ICU is compiled through macports without -O0, it expects /usr/lib/libgcc_s.1.dylib to contain ___divmoddi4. Sadly, it doesn't on Tiger.

nm /usr/lib/libgcc_s.1.dylib | grep divmoddi4
/usr/lib/libgcc_s.1.dylib(_udivmoddi4_s.o):
90bd5b6d T ___udivmoddi4

A more recent version of libgcc_s would have something like

nm libgcc_s.1.dylib | grep divmoddi4
00004480 T ___divmoddi4
000048b0 T ___udivmoddi4

Disabling compiler optimization prevents this. Sadly, I don't know of a better way.
