1 | niro | 532 | # ========================================================================== |
2 | # Building binaries on the host system | ||
3 | # Binaries are used during the compilation of the kernel, for example | ||
4 | # to preprocess a data file. | ||
5 | # | ||
6 | # Both C and C++ is supported, but preferred language is C for such utilities. | ||
7 | # | ||
8 | niro | 1297 | # Sample syntax (see Documentation/kbuild/makefile.txt for reference) |
9 | niro | 532 | # hostprogs-y := bin2hex |
10 | # Will compile bin2hex.c and create an executable named bin2hex | ||
11 | # | ||
12 | # hostprogs-y := lxdialog | ||
13 | # lxdialog-objs := checklist.o lxdialog.o | ||
14 | # Will compile lxdialog.c and checklist.c, and then link the executable | ||
15 | # lxdialog, based on checklist.o and lxdialog.o | ||

17 | # hostprogs-y := qconf | ||
18 | # qconf-cxxobjs := qconf.o | ||
19 | # qconf-objs := menu.o | ||

27 | # expr.o and type.o (they are both compiled as C code and the object file | ||
28 | # are made as position independent code). | ||
29 | # conf.c is compiled as a c program, and conf.o is linked together with | ||
