Hi Jeff, OpenCSW is not the default Solaris package. Is it a new requirement from grep-3.5 ? I can install other GNU software without OpenCSW, including grep-3.4.
Tried OpenCSW. $ sudo pkgadd -d http://get.opencsw.org/now and set /opt/csw/bin in PATH. (/opt/csw/gnu is not found.) But the result was the same. Comparing src/Makefile between CC=gcc & CC='gcc -m64', I found "LIBCSTACK = " with CC=gcc "LIBCSTACK = -lsigsegv" with CC='gcc -m64' and it is possible to build grep-3.5 with CC=gcc such as $ ./configure CC=gcc LIBCSTACK=-lsigsegv $ make $ make check Regards, --- Kiyoshi
