Hello Gilles thanks for your support, yes finally I could compile the library in the architecture that I used, I forced the compilation to entry in the "if _unix_" conditional compilation, but I assume that exist another way to do this. Do you have a example for enable that conditional compilation flags?
regarding to my dev/urandom, yes my platform has this feature, the library runs very well, but I just have the point related to "force" the compilation because the library doesn't recognize the unix architecture.
Thanks and we keep in touch!
Regards from Mexico!
BTW If I want to professional training, Do you offered this service?

Hi Palomo,
You seem to be compiling for a system with a Linux kernel, but with only a partial Unix userland. The “Unix” code in the entropy_poll module might work on your system, but it is only enabled if __unix__ or __unix (or a few others) is defined.
Can you please try the attached patch? Does your runtime environment have /dev/urandom ?
Regarding the knowledge base article, you need to remove the "." character at the end of the URL: https://tls.mbed.org/kb/how-to/add-a-random-generator--

Hello Hanno, Thanks for your thanks for you quickly replay.
I have an error compilation, I'm using nios2-linux-uclibc for my cross compilation and uclinux architecture, the linux kernel is 2.60 but I have this error when I try to compile the library, I want to use the library as a simple client using TLS1.2

Hi Palomo, Please take a look at the recent threadhttps://lists.trustedfirmware.org/pipermail/mbed-tls/2020-April/000069.html
which should give you a better understanding of how Mbed TLS manages and uses entropy from the underlying system. Regards, Hanno

I'm Palomo and I've been working with your library a few weeks ago, I'm using Linux kernel 2.60 but my embedded system has a limit entropy source, i now that this is a critical point, but How can I use your library if I want to use a other entropy source?
