使用 prc-tool开发 Palm 程序,makefile 是必不可少的,这和通用的 Makefile 没有什么大的区别,下面简要介绍一下。
如果不写Makefile, 需要依次输入以下命令:
1. Compile the .c file to .o file
m68k-palmos-gcc –O1 –c main.c –o main.o
m68k-palmos-gcc –O1 –c other.c –o other.o
2. Link into an executable file
m68k-palmos-gcc –O1 main.o other.o –o GNUSample.tmp
3. Split the object into application sections, produce a .grc file
m68k-palmos-obj-res GNUSample.tmp
4. Compile the resource (Use the pilrc to convert the static element to resource)
pilrc GNUSample.rcp
5. Build the application
Build-prc GUNSample.prc “GNU Sample” Eric *.bin *.GNUSample.grc
最容易看懂的,低级的 Makefile 就是老老实实把要编译的命令敲进去,只当是一个批处理文件用。我还挺喜欢这样的,不过如果以后程序扩展,修改的话,需要修改多处地方,可维护性差一点
all : helloworld.prc clean
helloworld.prc : code0000.helloworld.grc tver0001.bin
build-prc helloworld.prc "Hello world" HeWo *.helloworld.grc *.bin
ls -l helloworld.prc
tver0001.bin : helloworld.rcp ../resources/icon.bmp ../resources/icon_s.bmp
pilrc helloworld.rcp
code0000.helloworld.grc : helloworld.c
m68k-palmos-gcc -O2 helloworld.c -o helloworld
m68k-palmos-obj-res helloworld
clean :
rm helloworld *.helloworld.grc *.bin

复杂点的 Makefile,初学者不太容易看得懂,但是维护性比较高,比如下面这个,就需要一些 Makefile 的基础知识,如宏,依赖关系,规则等等。
推荐 《Linux程序设计》Chapter 8 系统学习。
