Hi I'm trying to install squid 2.6 STABLE12 on sparc-sun-solaris2.10 on ARCH=SunOS-5. I extract the tar and run ./configure --prefix=/local/mnt/squid/install Then when I make, I get "error: `SIGHUP' undeclared" However I have checked the include locations for signal.h etc and all seems to be in order. I also previously installed squid on another machine, with a slightly older gcc and everthing worked. Comparing the configurations, I don't see anything different. I am not sure as to where the issue lies, or what steps I should take from this point. I have copied the error message below. Any assistance in this matter would be greatly appreciated. Thanks Sharat I../include -Wall -g -O2 -MT cache_cf.o -MD -MP -MF ".deps/cache_cf.Tpo" -c -o cache_cf.o cache_cf.c; \ then mv -f ".deps/cache_cf.Tpo" ".deps/cache_cf.Po"; else rm -f ".deps/cache_cf.Tpo"; exit 1; fi cache_cf.c: In function `requirePathnameExists': cache_cf.c:3019: error: `SIGHUP' undeclared (first use in this function) cache_cf.c:3019: error: (Each undeclared identifier is reported only once cache_cf.c:3019: error: for each function it appears in.) *** Error code 1 make: Fatal error: Command failed for target `cache_cf.o' Current working directory /local/mnt/squid/squid-2.6.STABLE12/src *** Error code 1 The following command caused the error: failcom='exit 1'; \ for f in x $MAKEFLAGS; do \ case $f in \ *=* | --[!k]*);; \ *k*) failcom='fail=yes';; \ esac; \ done; \ dot_seen=no; \ target=`echo all-recursive | sed s/-recursive//`; \ list='fs repl auth'; for subdir in $list; do \ echo "Making $target in $subdir"; \ if test "$subdir" = "."; then \ dot_seen=yes; \ local_target="$target-am"; \ else \ local_target="$target"; \ fi; \ (cd $subdir && make $local_target) \ || eval $failcom; \ done; \ if test "$dot_seen" = "no"; then \ make "$target-am" || exit 1; \ fi; test -z "$fail" make: Fatal error: Command failed for target `all-recursive' Current working directory /local/mnt/squid/squid-2.6.STABLE12/src *** Error code 1 make: Fatal error: Command failed for target `all' Current working directory /local/mnt/squid/squid-2.6.STABLE12/src *** Error code 1 The following command caused the error: failcom='exit 1'; \ for f in x $MAKEFLAGS; do \ case $f in \ *=* | --[!k]*);; \ *k*) failcom='fail=yes';; \ esac; \ done; \ dot_seen=no; \ target=`echo all-recursive | sed s/-recursive//`; \ list='lib scripts src icons errors doc helpers tools'; for subdir in $list; do \ echo "Making $target in $subdir"; \ if test "$subdir" = "."; then \ dot_seen=yes; \ local_target="$target-am"; \ else \ local_target="$target"; \ fi; \ (cd $subdir && make $local_target) \ || eval $failcom; \ done; \ if test "$dot_seen" = "no"; then \ make "$target-am" || exit 1; \ fi; test -z "$fail" make: Fatal error: Command failed for target `all-recursive'
