Hi,all friends I build my project on Debian6-32bit platform, It works ok. I copy the build result to Debian6-64bit platform and run, it shows:error while loading shared libraries:libboost_regex.so.1.42.0:can not open shared object file:No such file or directory Then i do whereis libboost_regex.so.1.42.0, it shows: libboost_regex.so.1.42: /usr/lib/libboost_regex.so.1.42.0 /usr/lib64/libboost_regex.so.1.42.0 Then i add /usr/lib/ in ld.so.conf, then i run my project, it shows:error while loading shared libraries: libboost_regex.so.1.42.0: wrong ELF class: ELFCLASS64 I'm sure that install libboost-regex on Debian6-64bit platform, the lib don't compatible 32bit.
