 within BOOST_ROOT and if that path is NOT found then it will probably fall
 back on the system paths.


FindBoost.cmake in CMake 2.8.3 supports a new option to prevent searching
the system paths.  You should enable it if you are 100% sure that you will
never want to find something outside of BOOST_ROOT, CMAKE_PREFIX_PATH, etc.
Boost_NO_SYSTEM_PATHS

There was a bug related to not finding Boost libraries in a staging area.  I
believe this works now.

Also, take a moment and set this new variable appropriately (nearly all
users will want it to be OFF)
Boost_USE_STATIC_RUNTIME

[CMake] Linking Boost on Linux on 64bit host and 32bit target

Hi Kent.

 I have a project using Boost that should compile for both 64bit and
 32bit on a 64bit host.  This works fine for a 64bit target, but I
 can't get this to work for a 32bit target.

I'm having problems linking Boost too. But enough about me.

 In order to compile for 32bit on a 64bit host, I have a -D parameter
 called BUILD64.  Here is my logic to initialize this var:
 
 if( WIN32 )
   set( BUILD64 ${CMAKE_CL_64} )
 else()
   option( BUILD64 Build a 64-bit product OFF )
   if( BUILD64 )
   message( STATUS 64-bit build )
   endif( )
 endif()

Are you sure this logic is right? It looks very odd. Does CMake set
WIN32 for a 64-bit Windows toolchain? Didn't you say you were building
on Linux?

 The syntax for finding boost is thus:
 set( Boost_USE_MULTITHREADED ON )
 set( Boost_USE_STATIC_LIBS   ON )
 set( Boost_DETAILED_FAILURE_MSG   ON )
 # set( Boost_DEBUG ON )
 find_package( Boost 1.33.0 COMPONENTS program_options )

You don't set ADDITIONAL_VERSIONS. That's probably not the problem.
IIRC, it's:

set(Boost_ADDITIONAL_VERSIONS 1.44 1.44.0)

... if you wanted to try it anyway.

Hi Adam~

[Adam]
Are you sure this logic is right? It looks very odd. Does CMake set WIN32 for a 
64-bit Windows toolchain? Didn't you say you were building on Linux?

[Kent]
My software compiles cross platform, and we support windows too.  WIN32 is set 
for 64bit platforms.  I do have the windows build compiling properly with 
boost.  I'm specifically having problems with linux.

[Adam]
You don't set ADDITIONAL_VERSIONS. That's probably not the problem.
IIRC, it's:
set(Boost_ADDITIONAL_VERSIONS 1.44 1.44.0)

[Kent]
I did not originally set Boost_ADDITIONAL_VERSIONS.  I did set it now, and ran 
a clean recompile, but no change.  My Boost_LIBRARIES still came out as:
-- Boost_LIBRARIES: /usr/lib/libboost_program_options-mt.a

Even though I've specified BOOST_LIBRARYDIR as:
BOOST_LIBRARYDIR = /home/kknox/sdk/boost_1_44_0/stage/lib

Re: [CMake] Linking Boost on Linux on 64bit host and 32bit target

2010-11-03 Thread Knox, Kent 
Hello all~

I'm going to follow up on my email from last week with more information.  I 
don't believe that find_package( Boost ) is behaving properly in my case, and I 
need help with either a proper solution or a workaround.

I'm using Cmake 2.8.2, on a 64bit Ubuntu linux host, trying to compile a 32bit 
package with boost.  

I have manually downloaded and compiled boost 1.44 into my home directory, 
~/sdk/boost_1_44_0.  The system also has boost 1.40 installed using a package 
manager into /usr/lib.

I manually invoke cmake with this command line:
~/bin/cmake-2.8.2-Linux-i386/bin/cmake -G Unix Makefiles -D 
BOOST_ROOT=~/sdk/boost_1_44_0 -D BOOST_LIBRARYDIR=~/sdk/boost_1_44_0/stage/lib 
-D ATISTREAMSDKROOT=/usr/src/ati/ati-stream-sdk-v2.2-lnx64 -D BUILD64=OFF -D 
CMAKE_BUILD_TYPE=Debug  ../../code

Notice that I explicitly set BOOST_ROOT and BOOST_LIBRARYDIR, and the debug 
output seems to confirm my settings.

This is my output when I run 'make VERBOSE=1':

 wrong bitness.

Did you try to print out the value of Boost_LIBRARIES? Does that contain
the proper absolute path to the boost library? Are you actually using
that variable for your target_link_libraries call? The make-output looks
like either the variable doesn't get the right value which shouldn't
happen as its set using find_library or you're not using the variable
but instead simply pass program_options to the target_link_libraries
call. Oh and whats the value of Boost_program_options_LIBRARY?

[CMake] Linking Boost on Linux on 64bit host and 32bit target

2010-10-29 Thread Knox, Kent 
Hi all~

I have a project using Boost that should compile for both 64bit and 32bit on a 
64bit host.  This works fine for a 64bit target, but I can't get this to work 
for a 32bit target.  I've done a fair share of googling to find this answer, 
but have not stumbled across anything that helps.  In fact, the only flag that 
I can find to distinguish between 32bit build and 64bit builds only applies to 
windows with ${CMAKE_CL_64}.

In order to compile for 32bit on a 64bit host, I have a -D parameter called 
BUILD64.  Here is my logic to initialize this var:

if( WIN32 )
set( BUILD64 ${CMAKE_CL_64} )
else()
option( BUILD64 Build a 64-bit product OFF )
if( BUILD64 )
message( STATUS 64-bit build )
endif( )
endif()

The syntax for finding boost is thus:
set( Boost_USE_MULTITHREADED ON )
set( Boost_USE_STATIC_LIBS   ON )
set( Boost_DETAILED_FAILURE_MSG   ON )
# set( Boost_DEBUG ON )
find_package( Boost 1.33.0 COMPONENTS program_options )

The boost find package module doesn't appear at a glance to distinguish between 
64bit and 32bit builds;  I don't understand how it is supposed to work.  I have 
a feeling that it is expected that find_library is supposed to distinguish the 
path behavior, but I don't have it set up right.

When I compile and link for 32bit, I get:

Scanning dependencies of target Foo
[ 72%] Building CXX object client/CMakeFiles/Foo.dir/Foo.cpp.o
[ 81%] Building CXX object client/CMakeFiles/Foo.dir/openCL.cpp.o

[100%] Building CXX object client/CMakeFiles/Foo.dir/stdafx.cpp.o

/usr/bin/ld: warning: i386:x86-64 architecture of input file

`/usr/local/boost_1_44_0/lib64/libboost_program_options.a(options_description.o)'
 is incompatible with i386 output

As you can see, it is looking in lib64 instead of lib.  How do I change that 
behavior?

Thanks for any help,
Kent
