Subject: Problem in porting EPICS on microblaze softcore processor

Last few days ,I am working on porting EPICS in microblaze softcore processor with uClinux. For this I am trying to build a Channel access portable server code on it as referring the tutorial on Channel Access Portable Server Application Interface (API) by Philip Stanley.

It consists of four c++ files namely myServer.h,Ÿ myPV.cc,Ÿ myServer.cc and Ÿ Server.cc. I could successfully compile the cc files and generate the object files in uClinux (namely myPV.o myServer.o Server.o). But while generating executable named Server by linking the object files with the libraries libcas.a, libca.a, libCom.a, and libgdd.a i am stuck at an error. microblaze-uclinux-gnu toolchain is used for compilation. I know my problem is a bit specific, but if anyone who has worked with uclinux earlier may help me.

Following is the error output at the console 

microblaze-uclinux-g++  -L/home/petalinux-v0.40-final/software/petalinux-dist/lib -mno-xl-soft-mul -mno-xl-soft-div -mxl-barrel-shift -mcpu=v7.10.d  -L/windows/base-3-14-11/myserver2/microblaze_lib  -Wl -o Server myPV.o myServer.o Server.o -lcas -lca -lCom -lgdd -lrt -lc -lpthread
