Hi Mathieu,
I had a few build errors too on my 64b machine, when linking a static
library into a shared one such as :
/usr/bin/ld: ...: relocation R_X86_64_32 against `a local symbol' can not be
used when making a shared object; recompile with -fPIC
The fix I've had is to stick the following lines in the CMakeLists of the
appropriate libraries and it seems to work. (ripped off from KDE) :
# with -fPIC
IF(UNIX AND NOT WIN32)
FIND_PROGRAM(CMAKE_UNAME uname /bin /usr/bin /usr/local/bin )
IF(CMAKE_UNAME)
EXEC_PROGRAM(uname ARGS -m OUTPUT_VARIABLE CMAKE_SYSTEM_PROCESSOR)
SET(CMAKE_SYSTEM_PROCESSOR ${CMAKE_SYSTEM_PROCESSOR} CACHE INTERNAL
"processor type (i386 and x86_64)")
IF(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64")
ADD_DEFINITIONS(-fPIC)
ENDIF(CMAKE_SYSTEM_PROCESSOR MATCHES "x86_64")
ENDIF(CMAKE_UNAME)
ENDIF(UNIX AND NOT WIN32)

Hello,
I have the following two targets:
ADD_LIBRARY(foo STATIC ${foo_C_SRCS}) # C files
ADD_LIBRARY(bla SHARED ${bla_CPP_SRCS}) # CXX files
TARGET_LINK_LIBRARIES(bla foo)
When compiled with cmake on a 64bits machine I am getting:
...
relocation R_X86_64_32 can not be used when making a shared object;
recompile with -fPIC
...
Is this ok on most system, or there something against static lib
used in a shared lib ?
thanks,
