[SOLVED] Meeting problem of ‘undefined reference to'

(1/3) > >>

lukenothing:
Hello,

I'm just using Code::Blocks 10.05 on Ubuntu 12.04(precise) 64-bit few days.

Firstly, I created a c++ console project called A in /home/test/ccc/, then I created a C static library project called B which includes serveral files: libabc.a, abc.c, abc.h, etc. in  /home/test/abc/

I tired to using the /home/test/abc/libabc.a created by B in A.

But the ide always show the message as title 'undefined reference to ....'

I searched online and operated as most of them suggested as below:
1) right click the project A, and selected 'Build options',
2) click 'Linker settings' tab and click the 'add' button, pick the /home/test/abc/libabc.a from the prject B directionary,
3) click 'Search directories' tab and under in the sub-tab 'complier', there is an 'add' button, click it as well to select the 'abc.h'

That is all. I even add the /home/test/abc to the 'Search directories-Linker' list, the issure is still alive.

Could you help me?

You don't have to select the include file, but the path to the include file, so the compiler is able to find it.

Sorry about the time you wasted of, I just address the problem which is that after I add the libabc.a to the 'Link libraries', I also need to add an option to 'Other linker options' under the 'Linker settings', such as 'abc'.

Now the 'undefined reference to ...' is gone, but I get a new problem" g++: error: abc: No such file or directory'

Sorry, I make a mistake in description, you right, it'm impossible to add any .h files in that tab, the 'directories' is the only thing it accesses.

It seems that I did not really solve the problem...
