Hello all,

I'm trying to install Velvet 1.2.10 on an HPC. I keep running into the same problem during the "make" step. Below are the error messages:

rm obj/*.o obj/dbg/*.o 
rm: cannot remove ‘obj/dbg/*.o’: No such file or directory
make: [cleanobj] Error 1 (ignored)
cd third-party/zlib-1.2.3; ./configure; make; rm minigzip.o; rm example.o

Here is what I've tried: 1) Loading an older gcc version (4.9.3) 2) Using the command make 'BUNDLEDZLIB=1' 3) Making sure the makefile had -lm at the end of the cc -Wall -O3 -o velvetg obj/tightString.o ... -lm (of course all in variables now $LIBS)

Nothing has worked so far. Any suggestions would be appreciated!
