thank you for the reply. I am using Leopard on a MacBook.
On closer inspection of the log there is
c++ -c -pipe -Os -Wall -W -D__USE_WS_X11__ -I../../../mkspecs/darwin-g++ -I.
-I. -o iconv.o iconv.cpp
c++ -headerpad_max_install_names
-Wl,-dylib_file,/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib:/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries/libGL.dylib
-prebind -o iconv iconv.o
Undefined symbols:
"_iconv", referenced from:
_main in iconv.o
"_iconv_close", referenced from:
_main in iconv.o
"_iconv_open", referenced from:
_main in iconv.o
There seems to be a lot of activity on the fink lists regarding this problem
(not only in relation to qt4-x11) and I am not sure how to resolve it. I
tried various suggestions that had been posted and I even tried moving the
/usr/local directory out of the way but to no avail - stumped. I reinstalled
libiconv-dev, libiconv-bin and libiconv.
Your explanation would make sense to me - it appears as though the header
and the library are not matching.
thanks Alex
