1) gcc -c hello.c
Compile hello.c to object file.
2) ar rcs libhello.a hello.o
(or ar ruv hello.a hello.o)
Link object to static library.
3) gcc test.c -o test libhello.a
Compile executable file and link libhello.a
Compile hello.c to object file.
2) ar rcs libhello.a hello.o
(or ar ruv hello.a hello.o)
Link object to static library.
3) gcc test.c -o test libhello.a
Compile executable file and link libhello.a
To create the shared (*.so) library, use these steps
1) gcc -fpic -c hello.c
2) gcc -shared -o libhello.so hello.o
3) gcc test.c -o test -L. -lhello
1) gcc -fpic -c hello.c
2) gcc -shared -o libhello.so hello.o
3) gcc test.c -o test -L. -lhello
ar x /usr/lib/libx86.a
extract object file from libx86.a
ar t /usr/lib/libx86.a
Display a table listing the contents of archive…
extract object file from libx86.a
ar t /usr/lib/libx86.a
Display a table listing the contents of archive…
ar – create, modify, and extract from archives
t Display a table listing the contents of archive, or those of the files listed in member… that are present in the archive. Normally only the member name is shown; if you also want to see the modes (permissions), timestamp, owner, group, and size, you can request that by also specifying the v modifier.
If you do not specify a member, all files in the archive are listed. If there is more than one file with the same name (say, fie) in an archive (say b.a), ar t b.a fie lists only the first instance; to see them all, you must ask for a complete listing—in our example, ar t b.a.
If you do not specify a member, all files in the archive are listed. If there is more than one file with the same name (say, fie) in an archive (say b.a), ar t b.a fie lists only the first instance; to see them all, you must ask for a complete listing—in our example, ar t b.a.
x Extract members (named member) from the archive. You can use the v modifier with this operation, to request that ar list each name as it extracts it.
If you do not specify a member, all files in the archive are extracted. Files cannot be extracted from a thin archive.

nm – list symbols from object files
