Hello,
CPU: x86
OS: QNX 6.1.0A
I’m trying to build an application that uses Bessel functions. Why does
the app core dump (SIGSEGV) before main()?
Here’s what DL_DEBUG=1 reports:
load_object: attempt load of libsocket.so.2
load_elf32: loaded lib at addr b034e000(text) b035d4e0(data)
load_object: attempt load of libBLT24.so
load_elf32: loaded lib at addr b8200000(text) b83d8860(data)
load_object: attempt load of libX11.so.6.1
load_elf32: loaded lib at addr b0360000(text) b03f2660(data)
load_object: attempt load of libm.so.2
load_elf32: loaded lib at addr b03f8000(text) b0407e48(data)
load_object: attempt load of libbessel.so.1
load_elf32: loaded lib at addr b0409000(text) b040dee4(data)
Memory fault (core dumped)
Thanks,

What is libBLT24 ?
OK, BLT is the BLT extension to TCL/TK:
Can you post your code (everything leading up to main)? Is it possible
http://www.scriptics.com/ftp/blt/
ftp://tcl.activestate.com/pub/tcl/blt/
You’ll need TCL 8.3.2 and Tk 8.3.2
Let me move the Porting-BLT-specific to qnxrtp.porting.
you’re trying to declare a structure of monstorous size before main or on
main’s stack?
I don’t think so. The static version works well. My question for this
group is how do I get a handle on the source of this problem? I know
I’m three calls into libc, but that’s it…

It’s not necessarily libbessel that is the problem, it’s more likely something else. Check for bad
relocations in your shared libs (use objdump -h and look for rel.text or rel.rodata)
