Record #3690

Product Family: Software

Product Line: FPGA Implementation

Product Part: par

Product Version: 1.4.

Problem Title:
M1 Par or HITOP, ERROR: /usr/lib/dld.sl: Unresolved symbol: seekoff_9streambuf... libbasrw.sl running Xilinx DM through Mentor B.1-B.4



Problem Description:
Urgency: Standard

General Description:

When running M1 Design Manager through the Mentor Design Manager, by
running pld_dsgnmgr, on an HP 10.1 or HP 10.2 machine, PAR may error with
the following message:

ERROR:	/usr/lib/dld.sl: Unresolved symbol:
seekoff__9streambufFlQ2_3ios8seek_diri (code)
from /proj/sqabld/qahog/m1builds/x1_4.12/unix/bin/hp/libbasrw.sl
.
.
.
PROGRAM ABNORMALLY TERMINATED


HITOP may give a message similiar to the following:

usr/lib/dld.sl: Unresolved symbol: seekoff__9streambufFlQ2_3ios8seek_diri
(code) from /hwpkg/xilinxm1/bin/hp/libbasrw.sl
/usr/lib/dld.sl: Unresolved module for symbol:

Solution 1:

Basically with Mentor B.x there is a shared lib between Mentor and Xilinx,
for which they are incompatible. No matter how the SHLIB_PATH is set before
starting up pld_dmgr, Mentor will append the existing $SHLIB_PATH to the
$MGC_HOME/lib:$MGC_HOME/shared/lib, which is where the problem occurs.

The workaround for using B.x with M1 on an HP system is to exit pld_dmgr
and run 'dsgnmgr' from the UNIX prompt to process the design, then after
exiting Xilinx Design Manager (dsgnmgr), go back into 'pld_dmgr' to
finish up Timing Simulation etc. As long as the environment, namely the
SHLIB_PATH, is set properly, then no environment changes will be needed
when you exit pld_dmgr, run dsgnmgr, and then go back into pld_dmgr.

Development is currently working on a fix.

If you are not using Mentor and get this error, verify that the SHLIB_PATH
is set according to the Release Document that came with the software package.
It should look something like the following:

SHLIB_PATH=${XILINX}/bin/hp:lib:/usr/lib
