C++ 链接器脚本和C程序使用相同的头文件，这可能吗

例如，我想在0x10000000，0x100100000，0x100200000，.中放置一个特殊的数据.为此，我想在头文件中做，

#define DATA_START 0x100000000
#define DATA_GAP 0x100000
#define DATA0_START DATA_START + 0*DATA_GAP
#define DATA1_START DATA_START + 1*DATA_GAP
#define DATA2_START DATA_START + 2*DATA_GAP

现在，我想要有一个链接器脚本，并在那里定义部分，并想做一些类似的事情.(以便C程序和链接器脚本匹配).

. = DATA_START;
.mydata : {
  *(.data0)
   . = ALIGN(DATA_GAP);
  *(.data1)
   . = ALIGN(DATA_GAP);
...
}

of course with enough value for DATA_GAP so that data don't overlap.
But in linker script, the define statement is not "#define DATA_START 0x100000000" but "DATA_START = 0x100000000;". So if I want to use a single file to be used in C and linker script, how can I do it?? (I read somewhere that in programs there should be single point of truth, without having to fix data in multiple places..)
I know how to declare a variable in linker script and use it C program (using "var = ." in linker sciprt and using &var in C program..), but this time I want to statically allocate some data.
