Linking problems with latest libboost

[Quix0r]

I currently have this linking problem when it comes to linking executables:

[geoffthemedio]

Linking against 1.58 works fine for me on Windows.

Why do you call it the latest version, though? The boost site shows 1.60 as the latest release.

[codekiddy2]

I had similar link problem with boost 1.60, and the cause was missing macro definition during FO build.

I used following macros to fix the issue:

#define BOOST_ALL_NO_LIB 1   // do not auto link, instead you link manually to your import libraries.
#define BOOST_ALL_DYN_LINK 1 // tells you will link to shared libraries
#define BOOST_LOG_DYN_LINK 1 // explicitly says to link boost::log symbols to shared libraries

First macro puts "control" into your hands,
The second macro is supposed to link all shared libs only, but still it didn't work in my case, hence the 3rd explicit macro which fixed the issue.

[Quix0r]

@codekiddy2 Where did you add them?
@geoffthemedio It is the "latest distro version" I can get.

[codekiddy2]

You need to define these macros during compilation step, that is provide them to g++ compiler on command line.

ex:
g++ -DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK

If you use cmake to compile, the easy way is to supply these macros into "cmake-gui" by adding new "entry" prior to configuration.

On command line it is done like this:
https://cmake.org/cmake/help/v3.0/command/add_definitions.html

make sure your distro supplies shared boost libraries, otherwise this won't work.
In addition you will need to supply lib names to linker. to skip this part omit BOOST_ALL_NO_LIB

edit:
assuming boost auto linking is supported on linux, in which case lib names don't need to be supplied to linker. I'm on Windows so I can't tell.

[Quix0r]

Thank you. I let you know how it comes out. :)

Yes, linking again. 💃

[Vezzra]

Ok, I assume that means the issue is solved.

@codekiddy2, thanks for the assist 😃

[Quix0r]

I want to share my changes here. Sorry that I don't know much in C++.

Done. Na, I forgot to add the issue number in my message. :-(

@Vezzra ID: 6a63e3d

[geoffthemedio]

Can / should these defines be pre-added by the CMakeLists.txt files?

[codekiddy2]

With these defines linker will search for dll import libs, and those who built static boost libs only, will need to either build shared version of boost or modify Cmake files to link statically.

To make sure Cmake build works for everyone, Cmake files can be configured so that end user is given a choice for static link.

Sorry, I'm not sure how to properly modify Cmake files so I'm sharing my opinion here instead:

if (NOT FO_BOOST_STATIC_LINK)
add_definitions(-DBOOST_ALL_NO_LIB -DBOOST_ALL_DYN_LINK -DBOOST_LOG_DYN_LINK)
endif()

Now those who want static link simply invoke:

cmake -DFO_BOOST_STATIC_LINK=TRUE

[Vezzra]

@Quix0r, I've provided a PR that implements the fix at least for building on Linux: #449. Can you try to build Fo on your system with just that PR and no further modifications added by you?

[Quix0r]

Yes, that fix alone works as well. :) I have deleted my repository to not spread bad code.

[Vezzra]

Yes, that fix alone works as well. :)

Very good. I've created another PR with a better fix: #452. @Quix0r, can you test that one too, if it fixes the issue for you?

Hey guys,

I've tried building freeorion-0.4.7.1-r1 against boost-1.63.0 and it fails at linking stage with:

@madjestic, can you open a new issue for that? This issue is too old to be reopened, and although your problem seems to be similiar, it's not really the same AFAICT (the missing symbols are different ones).
