Undefined references for program_options library with mingw64.

[tasptz@…]

I compiled a shared version of boost program_options with mingw64. When I try to link against it I get:

Linking CXX executable ..\..\..\binary\abc.exe
CMakeFiles\abc.dir/objects.a(test.cpp.obj):test.cpp:(.text+0x65bf): undefined reference to `boost::program_options::detail::common_config_file_iterator::c

I use cmake for my project and everything works fine under linux. nm gives the following output:

The command I use to build boost is:

b2 --toolset=gcc variant=release address-model=64 threading=multi optimization=speed link=shared runtime-link=shared cxxflags='-DBOOST_USE_WINDOWS_H -std=gnu++0x -march=core2 -mtune=core2 -msse -msse2 -mssse3 -msse4' --with-thread --with-dat
e_time --with-filesystem --with-program_options --prefix=c:/temp/boost install

I attach a minimal cmake project (I used Boost 1.48.0 there, but it makes no difference).

In the attached project the boost headers are missing (file size limitation).

as your comment, the built libs on linux is working, but fails to work on windows, i think this is because of the common_config_file_iterator' export.

i add this fix, and it works on windows with .dll suffix:

class BOOST_PROGRAM_OPTIONS_DECL common_config_file_iterator

: public eof_iterator<common_config_file_iterator, option>

I've checked in a fix: ​https://github.com/boostorg/program_options/commit/4ae33ce15e5b6345e6eefa19466fdf7cd28a7bbd

Thanks for your patience.

[dani@…]

​https://github.com/boostorg/program_options/pull/1 fixes compilation failures on (at least) vc10, vc11, and vc12 introduced with commit 4ae33ce.

I'm surprised it didn't make it into 1.58.

[Vladimir Prus]

I would expect this to be part of 1.59: ​https://github.com/boostorg/program_options/commit/fae2d4c57b6c70e19e00cd6b93f4ef4f4c6681e2
