Ubuntu 12.04 configure apue2 environment

0. For ease of operation, it is recommended to use root permission.

1. Here http://www.apuebook.com/src.tar.gz downloads the source package and decompresses it to a directory, such as / root/apue.2e.

# tar-zxvf apue.tar.gz-C / root/

2. Change line 6 WKDIR=/home/sar/apue.2e in / root/apue.2e/Make.defines.linux to / root/apue.2e. (corresponding to the decompressed directory in 1)

3. Replace the status in line 122 in / root/apue.2e/ipp/ipp.h with Status. (it can also be replaced by something else, but it should correspond to the following 4)

4. Replace status in line 977 of / root/apue.2e/ipp/printd.c with Status. (corresponding to the above 3)

5. Replace the first line # include in / root/apue.2e/threadctl/getenv1.c and / root/apue.2e/threadctl/getenv3.c with # include.

6. Execute make. If the compilation is successful, the libapue.a static link library file is generated in the / root/apue.2e/lib/ directory.

7. Copy / root/apue.2e/lib/libapue.a to the / usr/local/lib/ directory.

# cp / root/apue.2e/lib/libapue.a / usr/local/lib/

8. Copy / root/apue.2e/include/apue.h to / usr/local/include/ directory.

# cp / root/apue.2e/include/apue.h / usr/local/include/

9. Compilation example: gcc main.c-lapue.
