C++11 not working anymore with clang 3.2
Hello there, I've installed the c++ (libc++ library) like this : make -C /usr/src/lib/libcxxrt all install make CXX=clang -C /usr/src/lib/libc++ all install Then, I was able to compile with clang++ using -std=c++11 -stdlib=libc++.

Kind of the opposite: UEFI expects GPT, but also expects a particular set of partitions. And then there's the SecureBoot situation. I thought GPT is supposed to replace MBR and UEFI is the future. Perhaps there is something in UEFI that can be tweaked to make it work with GPT? Yes. There should be some sort of legacy boot. In UEFI mode, SecureBoot can be disabled, so with the correct partition layout FreeBSD should boot even in UEFI (untested, I do not yet have a UEFI system). ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Touch screen support in 9 Release
Hello, My employer is going to replace my aging laptop soon. We've always used Macs at work but I'd kinda like to get back to FreeBSD. His criteria are Windows 8 and a touch screen, mine is decent FreeBSD support. So, what is the state of support for touch screens at the moment? Most if the information I can find is from four or five years ago, and I can't seem to find out what's going on now. And, any recommendations for a machine? I'd be using it primarily for web development.

A device may draw a maximum of 5 unit loads (500 mA) from a port in USB 2.0; 6 (900 mA) in USB 3.0. If the disk needs more than 500 mA to spin up and start properly, it won't work on a USB 2.0 port unless you use the external power supply. Also about usbus written that they are 2-port hub (probably built into the motherboard). In the first four usbus is intel UHCI root HUB, at the last - intel EHCI root HUB That kind of combination can often be found. My older home PC also had this kind of configuration (Intel EHCI, VIA UHCI). ls / dev / da * finds nothing camcontrol devlist outputs only DVD RW This shows that the disk isn't recognized by the OS, therefore not usable in any disk-related operation. My hdd has an input for an external power supply, and it is already connected to a second usb port. Also check the USB cable.
