I'm amazed no one else has run into this before but I thought I would list the issues and resolutions here so that anyone else who tries this can have an easier time and perhaps so the QScintilla documentation or build system can be changed to avoid these problems.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>First, you'll need to use the sudo command in front of the "make installs" everywhere since you won't have rights to write in the directories where everything gets installed without it.<DIV><BR class="khtml-block-placeholder"></DIV><DIV>The normal installation directions which don't work are:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> cd Qt4</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> qmake qscintilla.pro</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> make</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "> make install</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The directions I used for successfully building QScintilla using Qt4 on a Mac OS X are:</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV> cd Qt4</DIV><DIV> </DIV><DIV>Next you need to account for the default behavior on the Mac where qmake builds XCode projects.

This means that you need to include "/Library/Frameworks/" in the front of libqscintilla2.2.dylib in the section of the make file called LFLAGS just after the </DIV><DIV>open Makefile and add /Library/Frameworks/ to the front of libqscintilla2.2.dylib in LFLAGS just after the -install_name option.

There is some sort of problem with the includes being in their default position for the Qsci headers that causes a gcc error something like: "Error: template with C linkage". It appears that the gcc 4.0.1 compiler on the Mac OS X assumes that anything that is in /usr/include/ should be compiled with C linkage even if called from g++ (a really dumb idea I think)</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>The only way I found to fix this was to move the Qsci directory outside /usr/include/</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Since you need to tell configure.py where they are located later on when building the Python bindings, make it something easy to remember.
