Can't compile simple dynamic library about osxcross

[tpoechtrager]

This works:

OSXCROSS_MP_INC=1 o64-clang++-libc++ -O3 -dynamiclib EntryExit.cpp Callback.cpp -fdelayed-template-parsing -o bibtex_label_generator.dylib -IEndNote\ SDK/RSServices  -isystem . -lboost_regex-mt -lboost_system-mt

-fdelayed-template-parsing is important, otherwise you will get:

In file included from Callback.cpp:33:
./rapidxml/rapidxml_print.hpp:115:23: error: call to function 'print_children' that is neither visible in the template definition nor found by argument-dependent lookup
                out = print_children(out, node, flags, indent);
                      ^

        inline OutIt print_children(OutIt out, const xml_node<Ch> *node, int flags, int indent)
                    ^
[and so on...]

You must link against the libraries (-lboost-system, etc.). Also ensure you are using the right C++ standard library, boost is probably using libc++ and not libstdc++.

It still won't compile, now I get:

$ o32-clang++-libc++ -O3 -dynamiclib EntryExit.cpp -o bibtex_label_generator.dylib -I/cygdrive/c/local/EndNote\ SDK/RSServices -I/cygdrive/c/local/rapidxml-1.13 \
   -lboost-system -lboost-regex
ld: library not found for -lboost-system

In cygwin I have installed all the boost libraries and I tried with o32-clang++-libc++, o32-clang++, o32-clang++-libc++, and o32-clang++-stdc++. I have all the cygwin packages installed for libboost 1.58 and libboost-devel.

You must install the MacPorts packages:

$ echo "export MACOSX_DEPLOYMENT_TARGET=10.8" >> ~/.bashrc
$ echo "export OSXCROSS_MP_INC=1" >> ~/.bashrc
$ source ~/.bashrc
$ osxcross-macports install boost
$ o64-clang++-libc++ test.cpp -lboost_system-mt # boost is 64-bit!

I get the same error, after successfully installing the boost libraries (and I verified that they work with the compiler with a test program).

$ o64-clang++-libc++ -O3 -dynamiclib EntryExit.cpp -o bibtex_label_generator.dylib -I/cygdrive/c/local/EndNote\ SDK/RSServices -I/cygdrive/c/local/rapidxml-1.13 -lboost_regex-mt -lboost_system-mt

If you'd like to try to compile it yourself, you can get the necessary libraries here (endnote sdk is annoying to find)

No reply. Closing.

Sorry, I forgot about this, I don't have a mac to test on and the user I got to test the file couldn't get it working:

No problem! Feel free to reopen if you have any further questions.
