[Click] Building elements as a package

[Rajendra J. Magar]

Hi, Eddie

Thanks a lot for your response.

Here's the content of my CMakeLists.txt, which is the Makefile equivalent used by cmake.


INCLUDE_DIRECTORIES(/net/grad/magar/wlansec/code/common/network/include /usr/include/glib-2.0/include 
                     /usr/include/glib-2.0/glib /usr/lib/glib-2.0/include/ /data/map/analysis/vxl_bin/core 
                     /data/map/analysis/vxl_bin/vcl /data/map/analysis/vxl-1.4.0/core /data/map/analysis/vxl-1.4.0/vcl)
LINK_DIRECTORIES(/data/map/analysis/vxl_bin/lib)
LINK_LIBRARIES(vnl_algo netlib vcl vnl vnl_io vpl vsl vbl vul pcap glib-2.0)
ADD_EXECUTABLE(ecm ECM.cc)


This is from a standalone build. Now I would like to be able to take ECM.cc to Click so I can integrate with other elements coded by my project partner, but I am not sure what the above lines would translate into in Makefile.in. My sense is that stuff in INCLUDE_DIRECTORIES can be defined as CXX_FLAGS, that in LINK_DIRECTORIES as LDFLAGS and that in LINK_LIBRARIES as -lname_of_library. I have been relying on my very little knowledge of 'make' and trial and error to make these work, but I haven't succeeded yet.

If you are interested in the tarball of my project to help you help me, please let me know. I will send them your way instantly.

Thanks a lot,
Raz

Rajendra,

Click package makefiles are pretty simple and I would recommend you stick to 
the Click system.  It is a major headache to build makefiles that work with 
userlevel, linux 2.4, and linux 2.6.

Click package makefiles work as follows.

- Create a directory like etc/samplepackage
- Dump .cc and .c files in that directory
- Decorate those .cc and .c files with ELEMENT_PROVIDES()/EXPORT_ELEMENT() 
statements
- The makefile system should find all of those .cc/.c files and compile and 
link them together.

If you say a bit more about what cmake is doing for you someone on the list 
may be able to help.

automake is not the right approach for Click, btw.
