Certificate validation issue when trying to build qemu

[Ryan Long]

Hi,

I'm trying to build qemu, but I keep getting this error message.

RTEMS Source Builder - Set Builder, 6 (3950b1e2d857)
Build Set: devel/qemu
Build Set: devel/autotools-internal.bset
config: devel/autoconf-2.69-1.cfg

I am able to download it with a browser, but wget and curl won't work. Wget will work if I use the "-no-check-certificate" flag. Curl doesn't tell me of a flag that could bypass this.

Does anyone know why this is failing?

Thanks,
Ryan
