Hi Phillip, I missed this the first time I looked over your make.out file: checking for zlibVersion in -lz... no configure: error: zlib not installed make[4]: Entering directory `/home/pjmarz/gempak/GEMPAK5.11.4/extlibs/PNG/v1.2.25' make[4]: *** No rule to make target `all'. Stop. make[4]: Leaving directory `/home/pjmarz/gempak/GEMPAK5.11.4/extlibs/PNG/v1.2.25' make[3]: *** [_png] Error 2 make[3]: Leaving directory `/home/pjmarz/gempak/GEMPAK5.11.4/extlibs/PNG' make[2]: *** [/home/pjmarz/gempak/GEMPAK5.11.4/os/linux64/lib/libpng.a] Error 2 make[2]: Leaving directory `/home/pjmarz/gempak/GEMPAK5.11.4/extlibs/PNG' It seems that missing zlib is responsible for libpng not building. Can you check with rpm -qa that both zlib and zlib-devel are installed? -Michael > Michael, > > I ran make distclean and it ran into the same issue as before, it > created the objects in each folder then make halted progress after > checking the library. > Ticket Details =================== Ticket ID: DWW-382445 Department: Support GEMPAK Priority: Normal Status: Open
