[Qemu-devel] [PATCH] fix compile & linking errors on NetBSD

[Christoph Egger <Christoph.Egger@amd.com>]

[-- Attachment #1: Type: text/plain, Size: 799 bytes --]


Hi,

Attached patch fixes some compile and linking issues on NetBSD.

- change configure and bswap.h to get the bswap* functions
- adapt configure to link against -lrt to fix aio linking errors
- adapt configure to link against -lossaudio to fix oss linking errors
- add native softfloat fpu functions
