compiling Pike on NetBSD

[Jörn Clausen]

Hi!

I am trying to build Pike on NetBSD. I get a pike binary, but it crashes
when it tries to compile(?) post_modules/GL/gen.pike. I get this stack
trace from the generated core file:

I actually want to build the Roxen webserver, and compiling Pike there
with '-O0", I see

#0 0x000076730e9e81e4 in ?? ()
#1 0x0000000000431ad3 in eval_instruction (pc=0x76730e9e81e4

#2 0x00000000004358bb in apply_low_safe_and_stupid (o=0x76730e9af0d0,
offset=4) at /export/home/joern/roxen/roxen-6.1.2
46-src/pike/src/interpret.c:2926

When compiling the current Pike sources, I always get "optimized out",
even when turning off the optimizer with '-O0'.

Can anybody help me dig deeper to what the problem is?

The build environment is:

NetBSD 8.1/amd64 (i.e. 64-bit ABI)
GCC 5.5.0
all required prerequisites are installed (e.g. gmp 6.1.2 or nettle 3.5.1)


Is this from bin/README

smartlink
[FIXME: What does this do?]

part of the puzzle???


Thanks,
Joern

Try running paxctl +m on the pike binary. Alternatively you can try
compiling pike --without-machine-code.

The problem is most likely due to that recent releases of NetBSD have
changed the default policy regarding use of mprotect(2).

Wow, spot on! That fixed the immediate problem, now I can continue with
Pike and Roxen.

Argh, didn't see that when checking configure --help. I'll try that as well.

Thanks a lot for this quick help!

You might also want be interested in checking out my work in progress port of pike to pkgsrc. My plan is to get it submitted for inclusion to pkgsrc, I’d just like to get some more testing feedback.

As always, comments and suggestions are welcome!
