Hello,

When building MANA on CentOS Linux release 7.4.1708, gcc 9.1.0, and mpich 3.2, I get the following error message:
if mpicc -v 2>&1 | grep -q 'MPICH version'; then \ rm -f tmp1.sh; \ mpicc -show -static -Wl,--wrap -Wl,__munmap -Wl,--wrap -Wl,shmat -Wl,--wrap -Wl,shmget -o lh_proxy_da -Wl,-start-group \ lh_proxy.o libproxy.a gethostbyname-static/gethostbyname_static.o -L$HOME/mpich-static/usr/lib64 -lmpi -L$HOME/local_install/lib -llzma -lz -lm -lxml2 -lrt -lpthread -lc -ldl -Wl,-end-group | \ sed -e 's^-lunwind ^ ^'> tmp1.sh; \ sh tmp1.sh; \ rm -f tmp1.sh; \ elif false; then \ make libnl3.a; \ mpicc -static -Wl,--wrap -Wl,__munmap -Wl,--wrap -Wl,shmat -Wl,--wrap -Wl,shmget -o lh_proxy_da -Wl,-start-group \ lh_proxy.o libproxy.a gethostbyname-static/gethostbyname_static.o -L$HOME/mpich-static/usr/lib64 -lmpi -L$HOME/local_install/lib -llzma -lz -lm -lxml2 cat static_libs.txt-ldl -Wl,--end-group; \ else \ mpicc -static -Wl,--wrap -Wl,__munmap -Wl,--wrap -Wl,shmat -Wl,--wrap -Wl,shmget -o lh_proxy_da -Wl,-start-group \ lh_proxy.o libproxy.a gethostbyname-static/gethostbyname_static.o -L$HOME/mpich-static/usr/lib64 -lmpi -L$HOME/local_install/lib -llzma -lz -lm -lxml2 -lrt -lpthread -lc -ldl -Wl,-end-group; \ fi libproxy.a(sbrk.o): In function__sbrk':

Any help with this matter is much appreciated. Thank you for your time.
