lld: FATAL   
I'm using QNX 7.

I've rebuilt our PCI driver and when I tried to load it says it can't find the pcilib.so.2.0 and it's in the system. Any
 hint on how to move forward, any help is appreciated.

Thanks.
Hasan

Re: lld: FATAL   
Since this is a dynamic library, the program expects to find it in the same place as it was when compiled.   So it 
probably lives in /lib or /usr/lib or on the outside /usr/local/lib.

You want to create a link in the build file that mimics this eg.

libx.so -> /usr/lib/libx.so

Re: lld: FATAL   
It looks like a Makefile issue, I find in the map file that the pcilib used there as 32 bit but our actual target is 64 
bit.

LOAD H:/QNX700/target/qnx7/x86/lib/libpci.so
OUTPUT(C:/Users/super7/ide-7.0-workspace/CTI-QNX-700/src/ctiser/x86/o/devc-serCtiPciUart elf32-i386)

It will need to point to x86_64. We used the same make file that we used for QNX 6.6. I think if I get the makefile for 
64 bit then the issue will be solved.

We've been using sample serial driver for our serial cards for ~30 years. I don't see the sample serial driver  for QNX 
7, where do I get it? 

Thanks,
Hasan

How do I do this?

I've tried this in the build file 
[type=link] libpci.so.2.0=/proc/boot/libpci.so.2.0

Then it does not load pci server, saying that it can't find libpci.so.2.0.


#---------------------------------------------------------------------------------------------------
# libraries for new PCI driver
#---------------------------------------------------------------------------------------------------
libpci.so
[type=link] libpci.so.2.0=/proc/boot/libpci.so.2.0
[-followlink search=${QNX_TARGET}/${PROCESSOR}] /lib/dll/pci/=lib/dll/pci

Shouldn't the link line be as follows to create a link from /lib/libpci... to /proc/boot/libpci.... :

[type=link] /lib/libpci.so.2.0=libpci.so.2.0

giving you the following sequence in your build file:

#---------------------------------------------------------------------------------------------------
# libraries for new PCI driver
#---------------------------------------------------------------------------------------------------
libpci.so
[type=link] /lib/libpci.so.2.0=libpci.so.2.0
[-followlink search=${QNX_TARGET}/${PROCESSOR}] /lib/dll/pci/=lib/dll/pci

How did you add the x86_64 to your project? Did you use the 'addvariant' tool?

Re: lld: FATAL   
That's it, I needed to use addvariant tool for 64 bit binary, this is the reason for ldd error. Thanks a lot.
