Hi Jared, I see a missing header file for the PNG library, line 1126 in the log file: xpng.c:4:17: fatal error: png.h: No such file or directory The png.h file should be provided in $OS_LIB/include/ from the build of $NAWIPS/extlibs/PNG/ It seems that the file is not available because the build is incomplete, as your log file indicates that you've previously run "make all". My suggestion is to rebuild completely, cd to $NAWIPS and issue the command "make distclean" and then "make all >& make.out" and check the make.out file. If all looks good, a "make install" should have you ready to use GEMPAK.
