arm-none-eabi-gcc misses cstdint

Attempting to divert this to the right place. That said, this is really a question, so I'll convert it.

Please be noted that there are two gcc-arm-none-eabi toolchains in Trusty, one is shipped with Trusty and provided by Ubuntu, another is provided by us. After add our ppa repo, simply running "sudo apt-get install gcc-arm-none-eabi" will install the one provide by Ubuntu. You might run into some issues in this case.

To install tool chain provided by us, you need command "sudo apt-get install gcc-arm-none-eabi=4-8-2014q2-0trusty10". I am not understanding your question very well, but below case:

terguo01@terry-pc01:tmp$ cat x.cc
#include<cstdint>

volatile std::uint8_t x;

void
foo ()
{
x = 1;
}

can be successfully built with command "arm-none-eabi-g++ -S x.cc -std=c++11". I guess this can prove that we do have cstdint. Please confirm.

As already stated I had installed gcc-arm-none-eabin not gcc-arm-none-eabi=4-8-2014q2-0trusty10. Commonly I try to avoid to install PPAs and stick to the mainstream.

Today I added ppa:terry.guo/gcc-arm-embedded and installed gcc-arm-none-eabi=4-8-2014q2-0trusty10. First, upgrading failed because of conflicts with the standard trusty gcc-arm-none-eabi. After de-installing all "arm-none-eabi"-packages manually I could install the 4-8-2014q2-0trusty10 version.

I confirm that the new revision (and only the new revision) comes with cstdint (@ /usr/arm-none-eabi/include/c++/4.8.4/cstdint).

Another system (w/o ppa:terry.guo/gcc-arm-embedded) has no cstdint.

Thank you for pointing to the ppa.

Currently the standard gcc-arm-none-eabi from Ubuntu isn't supported by us. Instead the one from "ppa:terry.guo/gcc-arm-embedded" is supported by us. If you can confirm there is problem related to cstdint in gcc-arm-none-eabi from "ppa:terry.guo/gcc-arm-embedded", we definitely need to fix it as soon as possible. But if the problem is from standard gcc-arm-none-eabi, we will wait. This is because we are working with people from Debian/Ubuntu to try to consolidate those two gcc-arm-none-eabi tool chains. By the time they got consolidated, the problem should be gone.

I do confirm that the problem is only in the "standard gcc-arm-none-eabi from Ubuntu". There is no problem with "ppa:terry.guo/gcc-arm-embedded". Thanks a lot!
