Errors linking libhpx.so

[Shailesh-Tripathi]

Hello,
I am trying to install hpx (master branch) on Ubuntu 16.04. I am facing a linker error saying this:

sed_transform.cpp:(.text.ZN5boost12regex_searchIN9__gnu_cxx17__normal_iteratorIPKcNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEESaINS_9sub_matchISB_EEEcNS_12regex_traitsIcNS_16cpp_regex_traitsIcEEEEEEbT_SJ_RNS_13match_resultsISJ_T0_EERKNS_11basic_regexIT1_T2_EENS_15regex_constants12_match_flagsESJ[ZN5boost12regex_searchIN9__gnu_cxx17__normal_iteratorIPKcNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEEEESaINS_9sub_matchISB_EEEcNS_12regex_traitsIcNS_16cpp_regex_traitsIcEEEEEEbT_SJ_RNS_13match_resultsISJ_T0_EERKNS_11basic_regexIT1_T2_EENS_15regex_constants12_match_flagsESJ]+0x132): undefined reference to `boost::re_detail_106501::perl_matcher<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits, std::allocator > >, std::allocator<boost::sub_match<__gnu_cxx::__normal_iterator<char const*, std::__cxx11::basic_string<char, std::char_traits, std::allocator > > > >, boost::regex_traits<char, boost::cpp_regex_traits > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits > > const&, boost::regex_constants::_match_flags)'
collect2: error: ld returned 1 exit status
src/CMakeFiles/hpx.dir/build.make:2722: recipe for target 'lib/libhpx.so.1.1.0' failed

I realize that this is because the Boost regex library is not linked properly but I am not sure how to fix the issue.

I used the command like this :
`

sudo cmake -DBOOST_LIBRARYDIR=/usr/local/boost_1_65_1/libs -DBOOST_ROOT=/usr/local/boost_1_65_1 -DHWLOC_ROOT=/usr/local/share/hwloc -DHPX_WITH_MALLOC=system -DBoost_DEBUG:BOOL=ON /home/shailesh/Documents/stellar/hpx

`
and I got this warning but Configuring, generating was done and build files written.

failed to create symbolic link '/home/shailesh/Documents/stellar/hpx/my_hpx_build/share/hpx': No such file or directory

Ignoring the above warning I tried:

sudo gmake -j4

and then getting the linker error.

Kindly help me with this.
Thanks in advance!

Please make sure that you link against the same Boost libraries you compiled against. Also please make sure that Boost was built using the same ABI as HPX, i.e. all has to be either -std=c++11/-std=c++14/-std=c++17.

Hi @hkaiser ,
Thanks for your help. The issue was finally resolved. I installed the Boost library using the bootstrap script and everything went smoothly.
Thanks again
