[Scons-users] solving dependency cycle

[TOM TANNER (BLOOMBERG/ LONDON)]

Thats not a dependency cycle per se. Please could you give us the full error message, as that shows you what the cycle is between.

Also, how do you build x?

Hello,

how can I solve "dependency cycles" ?

I have got 3 source files (a, b c) that creates one target
finally = env.Program( ..., sources=[a,b,c] )

I have got a previous target x on which a, b and c depends:

finally depends on a, b, c
a depends on x
b depends also on x
c depends also on x

Scons creates the error, that it detects a dependy cycle. There is one, because
three targets depend on one. How can I solve this problem?
I try to use "SideEffect", so that only one of the targets builds x, but the cycle exists also
and Scons create an error. Can I tell scons, that it use only one branch of the graph to build x
and ignores the other one?

Thank

Phil
