dvblast links to -lev, which calls functions from -lm, like floor(). dvblast does not use libtool, so it does not pull in the libev dependencies when doing a static link. Fix that by always pulling in -lm after -lev. We can not do it from the .mk, because libraries passed from the .mk end up at the beginning of the list.

dvblast: fix static linking
|
|
|
|
dvblast links to -lev, wihch uses functions from the maths library,
|
|
like floor().
|
|
|
|
When linking to a shared libev.so, that dependency is automatically
|
|
pulled in because libev as a DT_NEEDED ELF tag on libm.so.
|
|
|
|
But when lnking to the static libev.a, since there is no way to express
|
|
such dependencies in static libraries, libm is not pulled in, which
|
|
leads to build failures such as;

|
Fix that by always linking to -lm (which must come *after* -lev).
