Yes, but now you need perl to build, apparently. cd ../src/desc && perl merge_822 ../functions/*/* > def-linux-i686-14787.tmp mv ../src/desc/def-linux-i686-14787.tmp ../src/desc/pari.desc cd ../src/desc && perl gen_proto gp pari.desc > gp_init-linux-i686-14787.tmp && perl gen_help gp pari.desc >> gp_init-linux-i686-14787.tmp I completly for got that src/desc/merge_822 was in perl, sorry...

Well, we could have a target that build all the autogenerated files. After running it, it should be safe to run parallel build since normally they should no more modify the source tree? Cheers, Bill.
