Thanks Marcel.
I have managed to solve the issue on the shared library, however, I'm
still having an issue with the executable being excessively linked.
I've tried a number of different ways, but don't think I have the
syntax right for what I'm trying to achieve.
====================================
# Dependencies
find_package (PkgConfig)
pkg_check_modules (DBUS REQUIRED dbus-1>=1.2.12)
pkg_check_modules (DBUS-GLIB REQUIRED dbus-glib-1>=0.80)
pkg_check_modules (FTDI REQUIRED libftdi>=0.13)
pkg_check_modules (GLADE REQUIRED libglade-2.0>=2.6.4)
pkg_check_modules (GTK2 REQUIRED gtk+-2.0>=2.16.1)
pkg_check_modules (HAL REQUIRED hal>=0.5.12)
# Main config
add_definitions(-DGLADEFILE="${CMAKE_INSTALL_PREFIX}/${sharedir}/galinette_gtk.glade")
add_definitions(-DGALINETTE_VERSION="${GALINETTE_VERSION}")
# Include & build
include_directories (. ${DBUS_INCLUDE_DIRS}
${DBUS-GLIB_INCLUDE_DIRS} ${GLADE_INCLUDE_DIRS} ${GTK2_INCLUDE_DIRS}
${HAL_INCLUDE_DIRS})
add_executable (galinette callbacks.c callbacks.h
galinette-gtk.c galinette_gtk.glade galinette-gtk.h hal.c hal.h
main.c)
add_dependencies (galinette libgalinette)
target_link_libraries (galinette libgalinette ${DBUS_LIBRARIES}
${DBUS-GLIB_LIBRARIES} ${GLADE_LIBRARIES} ${GTK2_LIBRARIES}
${HAL_LIBRARIES})
target_link_libraries (galinette LINK_INTERFACE_LIBRARIES "")
# Other resources
add_custom_target (galinette_gtk.glade)
# Install
install (TARGETS galinette DESTINATION ${bindir})
install (FILES galinette_gtk.glade DESTINATION ${sharedir})
====================================
>From what I can gather from the lists and documentation, executables
are handled slightly differently to libraries. To solve the library
issue, I used the following which worked correctly:
====================================
# Dependencies
find_package (PkgConfig)
pkg_check_modules (FTDI REQUIRED libftdi>=0.13)
# Include & build
include_directories (. ${FTDI_INCLUDE_DIRS})
add_library (libgalinette SHARED device.c error.c firmware.c
flash.c libgalinette.h libgalinette-private.h)
set_target_properties (libgalinette PROPERTIES PREFIX ""
LINK_INTERFACE_LIBRARIES "" SOVERSION 0)
target_link_libraries (libgalinette ${FTDI_LIBRARIES})
# Install
install (TARGETS libgalinette LIBRARY DESTINATION ${libdir})
====================================
set_target_properties doesn't seem to work on executables though.
Hopefully someone who knows a bit more than I do will be able to spot
what I'm doing wrong...
Kind regards,
Paul.
