Archiving static libraries: "could not read symbols"
 
Hi All,
I have two static libraries, and i need to create a single library by combining these two
i.e I have libone.a and libtwo.a and need to make libcombined.a by combining libone.a and libtwo.a

I tried
ar -rs libcombined.a libone.a libtwo.a
But when i tried to link this library to an exe i got the error

"libcombined.a:could not read symbols: Archive has no index; run ranlib to add one"

I tried running ranlib, but still i am getting this error , please help.

Try to extract all the objects from libone.a and libtwo.a then merge them all together:
Code:
$ ar -x libone.a
$ ar -x libtwo.a
$ ar -r -c libcombined.a *.o
this should recreate the index. Anyway, from the man page of ar:
Quote:
The ordering of members in an archive can make a difference in how programs are linked using the library, if a symbol is defined in more than one member.
this may bring to complications.
