Hi,
Â
I have built gcc 4.6.3 on Redhat 4.3, but it occurred below error when running testsuite with âmake âk checkâ:

DEJAGNU
 has already been installed and DEJAGNULIBS environment variable has 
been set: export DEJAGNULIBS=/home/linchongzhi/dejagnu/share/dejagnu as 
DEJAGUN is installed in /home/linchongzhi/dejagnu.

Here are my steps:
1. Configure gcc
--prefix=/home/linchongzhi/local/gcc-4.6.3
 --disable-multilib --enable-languages=c,c++ 
--enable-version-specific-runtime-libs --with-gmp=/ho
me/linchongzhi/local/gmp
 --with-mpc=/home/linchongzhi/local/mpc 
--with-mpfr=/home/linchongzhi/local/mpfr --with-ppl=no --with-cloog=no 
--disable-shared --enable-thread
s=posix --enable-__cxa_atexit --with-gnu-as --with-as=/home/linchongzhi/local/gcc-4.6.3/bin/as --with-gnu-ld
 --with-ld=/home/linchongzhi/local/gcc-4.6.3/bin/ld --with-
build-time-tools=/home/linchongzhi/local/gcc-4.6.3/bin
2. Build gcc
3. cd objdir; make âk check


My environment is:
X86_64, Redhat 4.3

I donât know why check-DEJAGNU error occurred and how to resolve it. Could you help? Thank you.

Best regards!
