There is an occasional race observed when building Busybox with parallel make.
It has been discussed on Busybox mailing list, see:
https://www.mail-archive.com/busybox@busybox.net/msg23244.html
There were several Busybox attempts to fix this issue:
0dddbc1a59795a77679d8c5ef48a2795cb470563 ("build system: always rewrite
NUM_APPLETS.h")
d8e61bbf13d0cf38d477255cfd5dc71c5d51d575 ("build system: different fix for
include/applet_tables.h/include/NUM_APPLETS.h")
Although the above patches alleviated the problem somewhat (also included in
this patches),
the race can still be observed. The error is consistently the same:
libbb/appletlib.c:164:13: error: 'NUM_APPLETS' undeclared (first use in this
function)
while (i < NUM_APPLETS) {
The reason is the include file where NUM_APPLETS is defined is not yet
generated (or is being modified)
at the time libbb/appletlib.c is compiled.
The attached patch fixes the problem by assuring libb is compiled as the last
directory.
