[CMake] CMake adds lib prefix to library. Bug?
Hi list.
Not sure if this is a bug or something stupid I've done. On several
Windows build environments (two XP, two 7, this happens with 2.8.2 and
2.8.3), I'm getting the error:
c:/compilers/mingw/bin/../lib/gcc/mingw32/4.4.1/../../../../mingw32/bin/ld.exe:
cannot find -llibodbc32
That's clear enough. It's also clear what the problem is: there is no
liblibodbc32.a in my environment. There is however a libodbc32.a, which
I would expect it to pick up.
With VERBOSE=1, make gives me a long g++ command ending with:
... -Wl,-Bstatic -llibodbc32 -Wl,-Bdynamic -lkernel32 -luser32 -lgdi32
-lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32
Which is correct apart from the -llibodbc32 part. (I'm not entirely
clear on why CMake felt it necessary to specify that it's a static lib
when it didn't with the previous ones.)
I've debugged my FindODBC.cmake with message(STATUS ${blah})
instructions and it returns odbc32, which is correct.
So my question is: why is CMake adding an extra lib? I can work
around it for now, but I'd like to solve this one properly.
Thanks,
Adam J Richardson

If I have ignored one of your non-bug-issue points from a reply to this thread, it's because it was not a bug number. If you still have an issue, open a bug and reply here with its number or start a new thread!! Argh. Fine.

Is there a way to have CMake do this by itself and not use absolute

that.
I've run into the same problem recently.
It seems to be because the underlying find_library() call returns full
paths instead of just library names. Linking against libraries as
inputs (specifying as full paths) instead of libraries (specifying
name with -l) seems to lead to inconsistent results on different
platforms.
Is this actually a CMake bug? Just after posting it occurred to me that
this might be a MinGW bug. Shouldn't g++ find the library whether you
give it C:\Compilers\Libs\libboost_thread-mgw44-mt-1_44.a or
-LC:\Compilers\Libs -lboost_thread-mgw44-mt-1_44?
The FindBoost script does set a Boost_LIBRARY_DIRS variable, so you
can use link_directories() to basically add the -L option. But I'm at
a loss as to how to properly set the -l options.
I suppose you could manually
set_target_properties(targ PROPERTIES LINK_FLAGS ${LINK_FLAGS}
-lboost_thread)
but that seems a little hackish. No, I'll poke some more at g++ and see
what I can come up with.

This always happens. Declare complete stumpitude and almost immediately
find a solution. This is the problem: I'm linking statically and
boost_thread wants to link dynamically.
The clue is in the first error in the build log: undefined reference
to `_imp___blablabla'. The _imp___ part gives it away. The fix is to
define BOOST_THREAD_USE_LIB in your CMakeLists.txt:
set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} -DBOOST_THREAD_USE_LIB=1)
I haven't tested it, but it builds without complaint now.
HtH,

[CMake] Bug fix requests for the *next* release of CMake...
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi David, Replies requested. CMake is already pretty awesome from my POV, but since you ask... Replies on this thread should just be a collector for bug numbers. Afraid I don't have a bug number, but I can explain quickly. If you have a particular issue that you think should be fixed for inclusion in 2.8.4, please bring it up now. Could you guys have a chat with the Boost guys and fix the future safety of FindBoost.cmake somehow? Fiddling with ADDITIONAL_VERSIONS is really a pain on a build farm. Oh, and include Mateusz Loskot's FindODBC.cmake in the release?

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

Hi all~
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.

[CMake] fun with Boost - swap absolute library path for -L and -l?
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1
Hi list,
I'm having some fun making link errors with the help of Boost on Win32.
With a main.cc of:
#include boost/thread.hpp
int main(int, char **) {
boost::thread t;
return 0;
}
and a CMakeLists.txt of:
cmake_minimum_required(VERSION 2.8)
project(orrible)
add_executable(orrible orrible/main.cc)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
set(Boost_ADDITIONAL_VERSIONS 1.44 1.44.0)
find_package(Boost 1.38 REQUIRED COMPONENTS thread)
include_directories(${Boost_INCLUDE_DIR})
target_link_libraries(orrible ${Boost_LIBRARIES})
I can produce the error:
CMakeFiles/orrible.dir/orrible/main.cc.obj:main.cc:(.text+0x17): undefined refer
ence to `_imp___ZN5boost6threadC1Ev'
CMakeFiles/orrible.dir/orrible/main.cc.obj:main.cc:(.text+0x2a): undefined refer

collect2: ld returned 1 exit status
make[2]: *** [orrible.exe] Error 1
make[1]: *** [CMakeFiles/orrible.dir/all] Error 2

Making with VERBOSE=1, we see the command line:
C:\Compilers\MinGW\bin\g++.exe -Wl,@CMakeFiles\orrible.dir\objects1.rsp -o
orrible.exe -Wl,--out-implib,liborrible.dll.a -Wl,--major-image-version,0,--mino

- -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32
-ladv
api32
Oddly enough, it links without complaint if I manually change the
command line to:
C:\Compilers\MinGW\bin\g++.exe
- -Wl,@CMakeFiles\orrible.dir\objects1.rsp -oorrible.exe
- -Wl,--out-implib,liborrible.dll.a

(That is, if I manually separate
C:\Compilers\Libs\libboost_thread-mgw44-mt-1_44.a into
