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
Thread model: posix
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?
