Adding library with .a extension

[ftl_embedded]

Hello Folks,

Can any one tell me on how to add .a library in qt creator.
My actual file name is DCCAPI.a. It is a DC Cheque Scanner. So i want to add this API definations on qt creator.
Kindly give your valuable feedback on the same.
Awaiting response.

Thanks

1) you'll need g++ compiler set up in qt creator (mingw will do the trick on windows)
2) in your .pro file add:

LIBS += -LPATH/TO/YOUR/LIB/ -llib_name

LIBS += -LPATH/TO/YOUR/LIB/ -llib_name

To copy to clipboard, switch view to plain text mode 

-L will point to directory where lib is. You can use $$PWD to point to your project directory. See path reference in Qt for other macros.
-l will point to library name.
3) add header reference to your sources.

note: lib name needed, not lib FILE name. That's why you don't have to put .a

I am using Ubuntu 14.04. Compiler is autodetected to g++. LIBS += -L/home/akkie/Desktop/test/ -lDCCAPI added this line in .pro. but it says cannot find -lDCCAPI..Y so?

you mean header reference like this..#include "DCCAPI.a"

Try doing

LIBS += "<absolute_path_to_.a>"

For example:
LIBS += "C:\Qt\Qt5.4.2\Tools\mingw491_32\i686-w64-mingw32\lib\libwsock32.a"

Getting error of Stray in program as mentioned above.
Is it related to memory?

No, that is because you have

#include "DCCAPI.a"

#include "DCCAPI.a"

Binaries are not included, only source text is (usually only headers).

Easy, remove that line.

how to add header reference to sources?

Also easy: include the header or headers of the library.

I have raspberry pi 2 1Gb which has arm controller. So when i try to install qt creator, it gives error of cannot execute binary file: Exec format error.
How do i fix this error?

Did you build the binary with a toolchain for ARM?
If not, doing so will likely fix this.
