Anyone with porting skills > interested to have a look? I have tried and apparently succeeded in building reduce on FreeBSD. Here is what i get: niobe% bin/redcsl Reduce (Free CSL version), 13-Dec-11 ... 1: (x+y)^4; 4 3 2 2 3 4 x + 4*x *y + 6*x *y + 4*x*y + y What i have done: downloaded reduce from subversion, then you have the choice of two lisps to build reduce psl and csl. Since i don't know how to get psl for FreeBSD i have done configure --with-csl gmake (note Gnu make). This does a lot of configuration, then builds the fox toolkit and then builds csl. Here i got two errors. One is in reduce-algebra/trunk/csl/cslbase/fns1.c One needs to add #include <sys/time.h> for example after "headers.h", otherwise timeval is unknown later on. The second is about RLIM_SAVED_MAX and RLIM_SAVED_CUR undefined in reduce-algebra/trunk/csl/cslbase/csl.c These are resource limits related to getrlimit(), which don't exist as such in FreeBSD. I have replaced the test at lines 1417 1418 by if (stackLimit != RLIMIT_VMEM) which i hope is correct. Then csl builds to the end and then reduce builds. At the end you get: Info: Recompilation complete if test -f reduce.app/Contents/reduce.img; \ then cp reduce.app/Contents/reduce.img /home/michel/pub/reduce-algebra/trunk/csl/cslbase/../../cslbuild/generated-c; \ elif test -f reduce.img; then cp reduce.img /home/michel/pub/reduce-algebra/trunk/csl/cslbase/../../cslbuild/generated-c; fi scripts/make.sh: arith: syntax error: "0>0 ? 0 : 0" I was puzzled by that, but in fact it means the build of reduce is completed. At this point you can run reduce as above. Now gmake install doesn't work and produces an infinite number of submakes. I don't know how to make a proper install. Hope this may help you to do a port .... -- Michel TALON
