7.4.6.29 Setting Heap Size from gnatlink

Under Windows systems, it is possible to specify the program heap size from gnatlink using either of the following:

• * -Xlinker linker option

  $ gnatlink hello -Xlinker --heap=0x10000,0x1000
  

  This sets the heap reserve size to 0x10000 bytes and the heap commit size to 0x1000 bytes.

• * -Wl linker option

  $ gnatlink hello -Wl,--heap=0x1000000
  

  This sets the heap reserve size to 0x1000000 bytes. Note that with -Wl option it is not possible to set the heap commit size because the comma is a separator for this option.
