<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal>I have a simple CMakeLists.txt file, in a directory called ‘multicast’:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>cmake_minimum_required(VERSION 2.6)<o:p></o:p></p>
<p class=MsoNormal>include_directories(../.. /usr/local/include/boost-1_38)<o:p></o:p></p>
<p class=MsoNormal>add_library(spreadx_multicast SHARED Message.cpp
MulticastChannel.cpp)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This successfully gives me a 64 bit .so:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>birju@cavewks7181:~/Dev/spreadx/multicast$ file
libspreadx_multicast.so<o:p></o:p></p>
<p class=MsoNormal>libspreadx_multicast.so: ELF 64-bit LSB shared object,
x86-64, version 1 (SYSV), dynamically linked, not stripped<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>However, there is a problem when I try and invoke that from
a directory above with the following CMakeLists.txt file:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>cmake_minimum_required (VERSION 2.6)<o:p></o:p></p>
<p class=MsoNormal>project (SPREADX)<o:p></o:p></p>
<p class=MsoNormal>add_subdirectory (multicast)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This gives me a 32 bit .so:<o:p></o:p></p>
<p class=MsoNormal>birju@cavewks7181:~/Dev/spreadx$ file
multicast/libspreadx_multicast.so<o:p></o:p></p>
<p class=MsoNormal>multicast/libspreadx_multicast.so: ELF 32-bit LSB shared
object, Intel 80386, version 1 (SYSV), dynamically linked, not stripped<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Why does it in one case generate a 64 bit lib, and in the
other, a 32 bit one?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>TIA,<o:p></o:p></p>
