Invoke dynamic libraries and static libraries in AIX environments

Prerequisite Knowledge:

Dynamic library suffix. So static library suffix. A

-c only compile not link

-O Specify Output name

-L Specify the lookup path for the link library

-l Specifies the link's library name

The-I file contains the header file, I followed the path of the lookup header file

The above can meet the compilation target

Generate. A file

Command AR

Q: Quick append. Add new modules to the end of the library

T view the members contained in the. a file

x extracts the members from the. A file, and if you do not specify the extracted members, it is extracted (note: Do not delete the members in the archive)

Cases:

G2dbt1:/wxp/so_a#ar T LIBHU.A
Libhu.o
Cmaps.o
sccsid.o
libhu_r.o
libhu32_r.o
libhu32.o

G2dbt1:/wxp/so_a#ar x libhu.a LIBHU.O
G2dbt1:/wxp/so_a#ls
LIBHU.A LIBHU.O

D Delete a member from a module

Cases:

G2dbt1:/wxp/so_a#ar D libhu.a LIBHU.O
G2dbt1:/wxp/so_a#ar T LIBHU.A
Cmaps.o
sccsid.o
libhu_r.o
libhu32_r.o
libhu32.o

M moves the members in the module in the order of a (moved to the back of the specified member) b (moves to the front of the specified module), and defaults to the last side if you do not specify the position to move

G2DBT1:/WXP/SO_A#AR-MB CMAPS.O libhu.a LIBHU.O
G2dbt1:/wxp/so_a#ar T LIBHU.A
Libhu.o
Cmaps.o
sccsid.o
libhu_r.o
libhu32_r.o
libhu32.o

V list additional information during execution

According to the above, if you create a. A file, the command is as follows:

/enpc/wxp/so_a$cc-c SAYHELLO.C
/enpc/wxp/so_a$ls
HELLO.C sayhello.c SAYHELLO.O
/ENPC/WXP/SO_A$AR-RV LIBHELLO.A SAYHELLO.O
Ar:creating an archive file LIBHELLO.A.
a-sayhello.o
/enpc/wxp/so_a$ls
HELLO.C libhello.a sayhello.c sayhello.o

command of function call. A

/ENPC/WXP/SO_A$CC hello.c-l./-lhello-o SayHello
/enpc/wxp/so_a$ls
hello.c libhello.a SayHello sayhello.c sayhello.o
/enpc/wxp/so_a$./sayhello
Say hello
/ENPC/WXP/SO_A$LDD SayHello
SayHello needs:
/USR/LIB/LIBC.A (SHR.O)
/unix
/USR/LIB/LIBCRYPT.A (SHR.O)

There's no libhello.a file in LDD's order.

static files, whether or not it is not important.

To produce a dynamic file:

Use the makefile file to produce a static library and invoke success

The file is not very successful yet.

Clean:
-rm *.o
-rm *.a
