How to add .so file to the makefile(LINUX)
 

I want to add a TBB dynamic library in Makefile.
I m using .libirml.so in the makefile. It shows the error like that:libirml.so.1 file not recognized: File format not recognized

How to proceed further TO finish the task?

whould be nice to show that makefile, also post what you have tried exactly and what was the error message exactly.

Need to include TBB libs in makefile.
 

TBB LIBS included in makefile are: -lirml -ltbb -ltbb_preview...

Error:TBB/libirml.so.1: file not recognized: File format not recognized
collect2: ld returned 1 exit status

looks like you mixed 32-64 bit libraries (or something similar).
what will file libirml.so.1 respond? What kind of OS/compiler do you have, what is your target platform?

Linux OS,TBB .so files and am include in Makefile but it return the error like tht.
gcc compiler .
I am using c++ in Linux OS.

As pan64 pointed out, there seems to be a problem with your libirml.so.1 file. Either it's not a valid library file or it is for a different architecture. You need to run the "file" command that pan64 posted and show the outputs.

To check whether .so file.1 is valid file or not.
 

How to check the libirml.so.1 file in Linux.

see post #4, but checking a single file is not enough, see #2

or you placed the lib in a non standard location
i have this issue sometimes if i build NEW code on older OS's

-- 64 bit defaults
/usr/lib64/LibName.so ( /usr/lib64/libQt5Core.so.5.3.2 )
/usr/lib64/GroupName/LibName.so ( /usr/lib64/gegl-0.2/gegl-buffer-load-op.so )


if not in /usr/lib64

you need to add it to ldconf
or if using autotools it has a .pc file for packageconfig
or
export the location in the makefile


if this is a simple hand wrote Makefile ( say 20 lines or so )
post it
