SIGSEGV while loading shared lib

QNX Newsgroups (Archives) qdn.public.qnxrtp.os

I have a simple prog doing nothing than printf().

its common.mk makes a reference to a shared lib of mine
(libgesecr.so0.0.1) but no symbols are referenced in the source.

When the prog starts, I get:
load_object: attempt load of libgesecr.so.0.1
load_elf32: loaded lib at addr b8200000(text) b82193e0(data)
load_object: attempt load of libDataServer_API.so.2.0
load_elf32: loaded lib at addr b821b000(text) b82204d0(data)
load_object: attempt load of libm.so.2
load_elf32: loaded lib at addr b034e000(text) b035de48(data)
load_object: attempt load of libRieter_misc.so.1.8
load_elf32: loaded lib at addr b8222000(text) b8225f1c(data)
segmentation violation (core dumped)

None of the referenced libs cause some errors except when libgesecr.so
is here.

I suppose there is something wrong with some declared symbols but I
didn’t see anything relevant with objdump.

All libs are built with standard QNX makefiles.

Any idea to find the problem?

Thanks,
Alain.

Did you build the libraries as PIC?

I found the problem.
In fact, the linker looks for libncurses in the local directory, then in
/x86/lib, /x86/usr/lib, etc.
The library libncurses.so.5.0 is in /x86/usr/lib, but the link
libncurses.so in only in /usr/lib. I don’t know why, certainly a problem
in the package I made.
So, ld didn’t find libncurse.so but found libncurses.a and used it.
Don’t really know why a sigsegv. Maybe you could make it more clear for me?

Thanks,
Alain.

I’m not sure that it would use libncurses.a, since it’s a static (archive)
lib. Execute your program as:

DL_DEBUG=1 ./myapp

and double check where it’s pulling the libraries, and which ones (post
that). Also, post an objdump -x and list the lib’s needed. What
address is it SIGSEGV’ing on?

Can you check libgescr.so.0.1 for text or rodata relocations.

objdump -h libgescr.so.0.1 | grep rel.text
objdump -h libgescr.so.0.1 | grep rel.rodata

Is there any DEBUG vs NDEBUG code in your lib?

Can you check libgescr.so.0.1 for text or rodata relocations.

objdump -h libgescr.so.0.1 | grep rel.text

Nothing.



objdump -h libgescr.so.0.1 | grep rel.rodata

Nothing.



Is there any DEBUG vs NDEBUG code in your lib?

Yes, three fprintf() are enclosed in #ifdef NDEBUG. But I removed these
