Question

Answer 1

+3 A:

Try out TARGET_LINK_LIBRARIES(ntctrl), the -l flag should not be used there (guess from what I have in mind)

This is how I would write the cmake file:

include_directories(/opt/norton/inc)
link_directories(/opt/norton/lib)
add_executable(application initialize_nw)
target_link_libraries(application ntctrl)

To show what are the actual command lines run during a make, use:

make VERBOSE=1

Maybe this shows you the difference between what you ran manually and the cmake generated commands.

Hello, thanks for the reply. Yes, I have actually tried that already (ntctrl). In my initilaize_nw.c I have included the header ntctrllib.h, so its including the header file as it doesn't show any error that it coudn't find it. Am I correct that TARGET_LINK_LIBRARIES is correct to use? Many thanks.

Hello, I am still having a problem when I specify the ntctrl library in the TARGET_LINK_LIBRARIES(ntctrl). The library is in the /opt/norton/lib directory. How does the TARGET_LINK... know that it need to search in the opt/norton/lib directory? Thanks.

LINK_DIRECTORIES is fine, maybe put the ADD_LIBRARY line before the TARGET_LINK_LIBRARIES, or even use ADD_EXECUTABLE instead (seems to me from the naming that application is not a lib)

Hello, I changed the ADD_LIBRARY before the TARGET_LINK_LIBRARIES. I had the same problem. However, if I compile on the command line like this: "gcc -I/opt/norton/include -L/opt/norton/lib -lntctrl initialize_nw -o application" I don't get any errors.

I edited the answer for better formatting (if that does not solve your issue, I am afraid I am then out of ideas), the name of the target shall be specified first when using target_link_libraries. I first thought it was positional by putting the target just before the links but I am quite sure now it is not: the name of the target must be specified.

Hello, thanks for your reply. However, I have followed this sample http://www.cmake.org/cmake/help/examples.html. But added my own source code in the Hello directory. The CMakeLists.txt in the Hello directory is what I am trying to change so that I can use the library ntctrl. I am all out of ideas now. There must be something I am doing wrong.

I made a check with my box (cmake 2.6 p4) works fine... I added a way to output the commands generated by cmake to help you find the difference between manual vs cmake command. I offer you to send me the files in a tar.gz so I can give it a try on exactly what you have.

jdehaan 2009-10-29 08:37:24

Ok thanks, I have the tar files, just me know where you want me to email them?

robUK 2009-10-29 10:12:28

Go to my profile -> my homepage -> impressum there you find my email (I don't want to post it here as I do not know how good it is obfuscated: these spammers drive me nuts ;-) )

jdehaan 2009-10-29 10:42:19

Ok, I have sent you an email. Thanks.

robUK 2009-10-29 11:16:16

I replied, but could actually find nothing useful. I simplified the files a bit and it works fine here. Curious to hear if it still fails for you.

jdehaan 2009-10-29 12:36:18

Hello, I have just checked my inbox, no email from you. Can you confirm it was sent? Thanks.

robUK 2009-10-29 14:21:41

I forwarded it a second time (the server is freenet and not color-of-code due to forwarding, maybe you have overseen it). The first time no error came back.

jdehaan 2009-10-29 19:23:02

Now I got this error back: 52-5.7.0 Our system detected an illegal attachment on your message. Damned, I will send you the attachment as .txt (actually a tar.gz). you can rename and unpack it.
