What does this mean and why is LLVM invoked? I'm using latest Xcode, Mac OSX 10.12.1, familiar with python but not command line installs or compilation....
The error is very simple. You only compiled BermudanSwaption.cpp but you also need to compile the entire QuantLib. Otherwise, the linker can't find the implementation.

Given a very simple fortran (95) function and a very simple c++ call to the program, I should be able to compile the program using:
g++ -c main1.cpp
gfortran -c test.f95
g++ main1.o test.o -o run
However, here I get the following error:
ld: warning: object file (test.o) was built for newer macOS version (11.5) than being linked (11.0)

Here, adding a -v tag before the -o tag and after the -o tag and the exe run did not solve the problem, as suggested by the error message.
The path:
/usr/local/include
/usr/local/lib
Outputs such an error:

How to fix this error?
I build the electron app with following scripts:
script/bootstrap.py -v --target_arch x64
script/create-dist.py
The first one ends successfully, but the second one throws this error (from TeamCity log):

It looks like the library and build machine are not compatible, but both of them are x64 platforms. What else can be wrong? I put here only part of the log, because it's really very long (thousands of lines). I used to use the same steps for building 1.2.3, 1.2.8 and 1.4.3 versions and there was no problem.
Try setting the ur valid architectures in xcode..
I am trying to compile dynamic lib in Mac OS X Mavericks, but when I try to link it, it says:
Undefined symbols for architecture i386:
"operator new(unsigned long, int, char const*, int)", referenced from:
...
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Compile flags I use:
Wall -Wextra -m32 -march=pentium4 -arch i386 -fvisibility=hidden
tried with
-stdlib=libc++ -lstdc++ -lc++
not helping.
gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.0.0

Please help!
EDIT:
Ok, lack of attention:
ld: symbol(s) not found for architecture i386
So, figured out that this is only happening when -g flag is present :)
For release build there is no error.
The question that arises is why there is no debug information symbols on MacOS X for libc++ (operator new). Any clues?
I'm working with FFMPEG on Mac OSX, my Mac version is 10.6.8 (i386).
When I try to compile my C++ code linking a dynamic library:
g++ sdk.cpp -rpath /usr/local/lib/libinsight.dylib -o sdk
I get the following error:
Undefined symbols for architecture x86_64:
"_main", referenced from:

"av_open_input_file(AVFormatContext**, char const*, AVInputFormat*, int, AVFormatParameters*)", referenced from:
ffmpeg_open(AVFormatContext**, char const*, int*)in ccCkx9dd.o
(so forth fo every FFMPEG call)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
Without linking dylib I have no problem. What's the matter?
P.S. ffmpeg version is Mach-O 64-bit executable x86_64
g++ sdk.cpp -rpath /usr/local/lib/libinsight.dylib -o sdk
Shouldn't you be linking to libffmpeg somewhere? Try adding -lffmpeg to your link command line.
