qscintilla build fails when tidy is installed

[ryandesign (Ryan Carsten Schmidt)]

After updating to qt4-mac @4.7.0_0, I now can't rebuild qscintilla:

/usr/bin/g++-4.2 -headerpad_max_install_names -single_module -dynamiclib -o libqscintillaplugin.dylib qscintillaplugin.o moc_qscintillaplugin.o   -L/opt/local/lib -lqscintilla2 -L/opt/local/lib -lQtDesigner -lQtScript -lQtXml -lQtGui -lQtCore  
ld: library not found for -lqscintilla2
collect2: ld returned 1 exit status
make: *** [libqscintillaplugin.dylib] Error 1

Mac OS X 10.6.4, x86_64. This was also ​reported on the mailing list.

libqscintilla2.dylib is located in /opt/local/libexec/qt4-mac/lib but I don't see any "-L/opt/local/libexec/qt4-mac/lib" up there.

Also, I guess that's not really the first error; the first error is:

error: there are no arguments to 'PLATFORM_ASSERT' that depend on a template parameter, so a declaration of 'PLATFORM_ASSERT' must be available

two thoughts: 1) can you try:

sudo port clean qscintilla
sudo port selfupdate
sudo port install qscintilla [+variants]

and see if that helps? Sometimes cleaning & updating does. If not, then:

2) "PLATFORM_ASSERT" is defined in the file "${worksrcpath}/include/Platform.h", which is included by the cpp file of issue via the header "ScintillaQt.h". The only way that these #define won't happen is if "PLATFORM_H" is already defined -- that would really mess things up for Qsci. I can't find another #define of it on my system (including /opt/local and /usr/local), but maybe you do on yours & it's messing up the install? Can you insert some code at the top of the Platform.h file & see what happens?

#ifdef PLATFORM_H
#define PLATFORM_H
#endif

and if at entry PLATFORM_H is already defined then GCC will print out a message about where it is already defined. Code compilation will not get any further than what you already have.

In my case it turns out this was caused by the presence of /opt/local/include/platform.h which is provided by the tidy port. Deactivating the tidy port while building qscintilla fixed it.

[michaelld (Michael Dickens)]

I've checked in r72688: a trial fix that does no harm on my system (which uses a case-sensitive file system) & should work on those using a case-insensitive file system -- which, really, is the issue since the source code includes "Platform.h" while tidy installs "platform.h". Please do a "selfupdate" & try again with tidy still installed and active.

Yes, that works, thanks.
