| dvblast: fix static linking |
| |
| dvblast links to -lev, which 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; |
| http://autobuild.buildroot.org/results/1f0/1f02f84fb926839a1adbe3af457bb909fdc44433/build-end.log |
| |
| Fix that by always linking to -lm (which must come *after* -lev). |
