Re: [cdt-dev] How to link a library? Is the library tab missing - help says it should be there?
|
Okay so I fixed my issue:
I needed to drop the .dll and the lib - which I had actually found this
solution online but another problem that by coincidence occurred when I
tested this option stopped me from realizing that I had solved my
original problem.
However, it still remains that the library tab is missing and that you
have to use the settings area to add libraries.

I am trying to link a library to a project. I thought this would be
very simple so please in form me if I have missed the simple solution.
As far as I can see I first go to project properties. I then have two
options:
Option 1:
C/C++ Build -> Settings -> MinGW C++ Linker -> Libaries
Add my libraries here. Should I use the full path to the library i.e.
C:\MySQL++\lib\mysqlpp.dll? And should I place this in the -l or -L
section? I am I correct in thinking that the -L area will link to the
library as a dll but the -l area will compile the library into the exe.
Option 2:
C/C++ General -> Paths and Symbols
Now according to the help file there should be a Library Paths tab and
a Libraries tab. I only have a Library Paths tab and no Libraries
tab??? Is the help out of date? If so where should I add Libraries
(besides the option I mentioned above)?
Some experimenting around in here revealed that if I add stuff to the
Library Paths then it is added to the -L area discussed in Option 1
above. This is also true for include files you add to the Includes
tab. Hence, I am guessing that this area is kind of a front end for
the more complex and lower level C/C++ Build -> Settings. Without the
Libraries tab however I am not sure how this would have added in
libraries to the settings - I assume it would add them to the -l area.
Despite my attempts to add the library I cannot get my program to link
correctly. I have tried:
# Library path in -L and library name in -l i.e. -LC:\MySQL++\lib\ and
then -lmysqlpp.dll (oh and btw I am not appending the -l myself to the
library I am letting Eclipse do that for me- so my entry looks like
mysqlpp.dll)
#Full path in -L C:\MySQL++\lib\mysqlpp.dll
#Full path in -l C:\MySQL++\lib\mysqlpp.dll
#Full path in -l C:\MySQL++\lib\mysqlpp.dll and path in -LC:\MySQL++\lib\
none of these have worked so far - I get undefined reference to
function errors.
Any help much appreciated.
Kind Regards
