2-4-2. 다른 Platforms에 Run-time Code 포팅

모든 platform 사양 내용은 소프트웨어가 설치된 루트 디렉토리의 platform.mk에 있습니다.

다른 platform 에 Run-time code를 포팅하는 방법은 아래와 같습니다.

1.     Create a directory tree containing a root directory (the name does not matter) and lib, src, rt*src, and build_lib subdirectories (note: in these definitions, * is a wildcard character indicating there are multiple directories matching this pattern). The tree should be as follows:

2.     Copy the files ending in extension ".mk" from the root directory of the installation to the root directory of the target platform (note: if transferring from DOS to UNIX or vice-versa, FTP the files in ASCII mode to ensure lines are terminated properly).

3.     Copy all files from the src and the different rt*src subdirectories from the installation to the src and rt*src directories on the target platform (note: if transferring from DOS to UNIX or vice-versa, FTP the files in ASCII mode to ensure lines are terminated properly).

4.     Copy the makefile from the build_lib subdirectory of the installation to the build_lib subdirectory on the target platform (note: if transferring from DOS to UNIX or vice-versa, FTP the files in ASCII mode to ensure lines are terminated properly).

5.     Edit the platform.mk file in the root subdirectory and modify the compilation parameters to fit those of the compiler of the target system. In general, the following parameters will need to be adjusted:

a.  CC C compiler executable name
b.  CCC C++ compiler executable name
c.  CFLAGS_ Flags that should be specified on the C or C++ command line

The platform.w32 and platform.gnu files in the root directory of the installation are sample files for Windows 32 (Visual C++) and GNU compilers respectively. Either of these can be renamed to platform.mk for building in either of these environments.

6.     Invoke the makefile in the build_lib subdirectory.

모든 파라메타 설정이 정확하다면, lib 서브디렉토리에 바이너리 라이브러리가 만들어질 것 입니다.
