Build Profile

The build profile used by the configure command is an argument of the mkmerge command. There is one default profile for each board, as shown in Table 2-1. For non standard system generation, customize the build profile by using the information on the file entries described here.

The build profile contains entries of the following type:

• <var>=<value>

The range of <value> values depends on the variable. Note that:

• on and yes are equivalent values (both mean "included")

• off and no are equivalent values (both mean "not included")

Table 4-1 Entry Type for Build Profile, Defined for PowerPC/ppc60x

merge_dir=<dir>	Specifies the path of the merged tree. <dir> will be created if necessary.
tree=<dir1dir2,...>	Specifies directory paths of the split source tree that you want to merge.
target=<ppc>	Specifies the target platform.
debug=<off|on>	The entry is required if the kernel is to be compiled with the DEBUG option set. Default is off.
optim=<off|on|size|speed>	Specifies if and how you want to optimize the compilation of your kernel. size focuses on size, speed on speed while on is a good compromise. Setting optim to speed may make symbolic debugging impossible. Default is on.
profile=<off|on>	Needed if you want to profile your system. Default is off.
locks=<rt|gp>	Specifies the implementation of locks within the core executive.
