[SOLVED] 0.9.0 compilation problem, libboost

[m0Ray]

Code:

  CXX      util.o
In file included from util.cpp:69:0:
/usr/include/boost/program_options/detail/config_file.hpp: In instantiation of ‘bool boost::program_options::detail::basic_config_file_iterator<charT>::getline(std::string&) [with charT = char; std::string = std::basic_string<char>]’:

make[3]: *** [util.o] Error 1

Linux, libboost 1.49.0 and gcc 4.7.2.

While searching for similar problems and solutions, I found that this problem in bitcoin was eliminated about 2 years ago. I found even special workarounds in util.cpp (bitcoin) and config_file.hpp (libboost includes) code. But now, as I see, this problem is back again.
Version 0.8.6 compiles without any problems. I tried to compile 0.9.0 on another distro with libboost 1.53 and it works. But I need 0.9.0 on my «tried and true» distro...

I never used libboost in my programs and now trying to understand, what happens, but still no success.

Can anyone help?

It's requesting another function than in the workaround. Can you try adding this line?

Code:

diff --git a/src/util.cpp b/src/util.cpp

Applied the patch, still the same error.

Seems like a redundant line.

I created a patch to revert the move of the lines that provided the workaround for older boost versions. Someone moved those lines after the boost includes which is not correct.
Can someone please inform the bitcoin developers about this?

Code:

# Between bitcoin 0.8.6 and 0.9.0 a workaround for older versions of boost
# was moved a bit down in the util.cpp file, thereby rendering it useless.
# This patch reverses that move of code.

Applied alienbob's patch, works ok with 0.9.0 and 0.9.1.
Thanks!
