Anyone could confirm the full list of impacted tools (glibc/binutils...) ?

Actually, up to now I thought, endianess is determined by the CPU and cannot be changed easily. I chose my kernel and architecture settings based on those of OpenWRT and the CPUs I use are mainly: * Ubiquiti RouterStation Pro (Atheros AR7161r2/MIPS 24Kc V7.4) * TP-Link WDR4300 (Atheros AR9344r2/MIPS 74Kc V4.12) * TP-Link Archer C5 (Atheros QCA9558v1/MIPS 74Kc V5.0) > > Please let me know if there is anything I could do to help avoiding the > > drop. > > We need some more build machines, current we use some ER8s, > which use NFS as rootfs and they have no FPU. > So the performance and stability are bad. I could only offer a spare RouterStation Pro which I use for testing and compiling/backporting some software like swconfig or hostapd. At least this device seems stable although it is even older/weaker than those ER8s... > We also need some more manpower to fix the FTBFS in future. The issues tagged 'mips' are way out of what I can handle, I am afraid. Though, I'll keep watching them and hope that there might appear issues I can deal with! all the best, Adi Kriegisch

Just for reference why is mips (mips32eb) not build from an mips64el machine (with FPU) ?

I am using mips32eb a lot on wifi routers (self-compiled kernel with rootfs on a usb stick). There are some people here at a community wireless network that do use such setups on their rooftops as well. Please let me know if there is anything I could do to help avoiding the drop. best regards, Adi Kriegisch
