porting bind-8.2.3 on ARM7

Hello, All!



Did anybody try to compile bind-8.2.3 for ARM7 target? I was able to compile only library libbind.a (although it took some efforts), but nevertheless I can't use this library properly. For example, if I link it with my application, I get the error like this:



/ext/mrv/my_local/usr/local/bind/lib/libbind_arm.a(res_send.o): In function `send_dg': /ext/mrv/wrk/dhis/bind/src/lib/resolv/res_send.c:705: undefined reference to `pselect' /ext/mrv/my_local/usr/local/bind/lib/libbind_arm.a(eventlib.o): In function `__evGetNext': /ext/mrv/wrk/dhis/bind/src/lib/isc/eventlib.c:303: undefined reference to `pselect' collect2: ld returned 1 exit status



Seems the problem is in 'pselect' behavior on target platfrom (i.e. ARM). Does anybody can give some clue.



Thanks.

It seems that you do not have the library with the function pselect() in your target.

IIRC, pselect() is a POSIX function, not in the most basic of C runtime libraries.

I checked my copy of newlib sources. There is only a module for select(). The manpage says that the function pselect() is in glibc2 (the full-size Linux C runtime), and that it is not completely implemented as for the signal race.

You could try get the glibc2 source of the function and add it to your code as a separate module.

HTH

In case if I will port bind9, I should also compile a few libraries (that are linked to bind) with arm-compiler, and it will cause new problems.

Anyway thank you for your advice.
