I've narrowed it down further.

-D_GLIBCXX_DEBUG=1 

Xcode generates the following compile statement (with some extraneous '-I' flags remove for readability):

> /Developer/usr/bin/gcc-4.0 -x c++ -arch i386 -fmessage-length=0 -pipe -Wno-trigraphs -fpascal-strings -fasm-blocks -O0 -Wreturn-type -Wunused-variable -D_GLIBCXX_DEBUG=1 -D_GLIBCXX_DEBUG_PEDANTIC=1 -I/usr/local/include -c main.cpp -o /Users/me/sandbox/QLtest/build/QLtest.build/Debug/QLtest.build/Objects-normal/i386/main.o

then linking, with the linking statement Xcode generates, leads to build errors, whereas:

> /Developer/usr/bin/gcc-4.0 -x c++ -arch i386 -fmessage-length=0 -pipe -Wno-trigraphs -fpascal-strings -fasm-blocks -O0 -Wreturn-type -Wunused-variable  -D_GLIBCXX_DEBUG_PEDANTIC=1 -I/usr/local/include -c main.cpp -o /Users/me/sandbox/QLtest/build/QLtest.build/Debug/QLtest.build/Objects-normal/i386/main.o

is successful.

So the question is now:

1) what is -D_GLIBCXX_DEBUG=1 ?

2) how to get XCode to drop the -D_GLIBCXX_DEBUG=1 ?  

3) I suppose an alternative question is if there is some in QuantLib that is interferring with whatever this flag is supposed to do, because adding the flag to the compile of other code doesn't seem to generate the same problem.

Thank you.

Bart.

If the following command line compile/link  works (note this is run  

in

the project directory for Xcode and main.cpp is just a "Hello, World"

with  #include<ql/quantlib.hpp> added to it) :

c++ main.cpp -o tql -L/usr/local/lib -lQuantLib

Then why does Xcode get 15 (and only 15) build errors?

What are the errors?
