Re: [Cppcms-users] ICU lib error in building cppcms 64bit environment

[Artyom <art...@ya...>]

Few points for Linux newcomer:

1. Stop working as root! It is very bad habit!

2. Install icu using 

     apt-get install libicu-dev 

   and stop compiling it on your own.

3. Remove all files from build directory and run cmake .. and then
   make again.

If you really what to build ICU on your own, build the default
version without any flags, it would build shared version.

Not, there is not import libraries crap so you link against shared
objects directly. But the code, as you mentioned should be compiled
with -fPIC - make it position independent - suitable for shared objects,
static libraries are usually compiled without this option
as expected to be used in static libraries.

P.S.: There should be no problems on 64 bit platform as I develop it
      mostly on 64bit one :-)
