synopsys VCS errors recording

1. vcs_save_restore_new.o: relocation R_X86_64_32S [Ubuntu 18.04]

$VCSHOME/linux64/lib/vcs_save_restore_new.o: relocation R_X86_64_32S against undefined symbol `_sigintr' can not be used when making a PIE object; recompile with -fPIC

/usr/bin/ld: final link failed: Nonrepresentable section on output

collect2: error: ld returned 1 exit status

Answer:

 1. install gcc-4.8 : 'sudo apt install gcc-4.8 g++-4.8'
 2. start vcs : vcs -full64 -cpp g++-4.8 -cc gcc-4.8 ...

 So, In makefile: VCS = vcs -full64 -cpp g++-4.8 -cc gcc-4.8 ...

Answer:

VCS use option: -LDFLAGS -Wl,--no-as-needed

So,  In makefile: VCS = vcs -full64 -cpp g++-4.8 -cc gcc-4.8 -LDFLAGS -Wl,--no-as-needed
