Hi, This is a pretty simple quesion, I was wondering if anyone here compiled povray on an Opteron, and if so what flags were uses in the Makefie CFLAGS and CXFLAGS options. I just cannot get it to compile any help regarding this matter will be great. Here is the error that i am getting Making all in src make[1]: Entering directory `/arnold/keg/anandab/download/povray-3.50c/src' c++ -DPREFIX=\"/usr/local\" -DPOV_LIB_DIR=\"/usr/local/share/povray-3.5\" -DCOMPILER_VER=\".Linux.gcc\" -DSYSCONFDIR=\"/usr/local/etc\" -DUSE_IO_RESTRICTIONS=\"\" `if [ "Xgcc" = "Xgcc" ]; then echo "-Wno-multichar"; fi ` -O3 -finline-functions -ffast-math -fomit-frame-pointer -funroll-loops -fexpensive-optimizations -foptimize-sibling-calls -minline-all-stringops -Wno-multichar -c bbox.cpp In file included from bbox.cpp:47: optout.h:49:2: #error You must complete the following DISTRIBUTION_MESSAGE macro bbox.cpp: In function `int sort_and_split(BBOX_TREE**, BBOX_TREE**&, long int*, long int, long int)': bbox.cpp:1872: warning: assignment to `long int' from `double' bbox.cpp:1872: warning: argument to `long int' from `double' make[1]: *** [bbox.o] Error 1 ################################################## What should my correct compiler flags be. thanks PS this might be a trivial problem so sorry for bothering anyone. -Ananda -- Recruiter: "How do you write a perl script?"
