Hello- Someone e-mailed me asking how I went from tarred source to executable and also indicated that there is not this information at opendx.org.
In the spirit of Chris Pelkie's scientist who just wants a tool to make pretty pictures, I offer the following to help a minimally compentent user (like myself) build dx. This could go in a README or at opendx.org. -Randy
building OpenDX4.0.10 on Aix 4.2 inital notes: I am in no way any expert. With the help of others I managed to build a runable verison of DX. Two explicit examples are provided with two compilers, gcc and xlc. The xlc version seems to be more stable. Here is a brief description of the additional libraries that can be built into dx. CDF, netCDF and HDF are data file format libraries(dx looks for HDF4). CDF and netCDF are required to run the samples and tutorial. Mesa3d is a graphics library which is necessary if there is not another GL library installed. ImageMagick is an image file format library(optional). Java required for java-enabled dx(optional). Source location: http://nssdc.gsfc.nasa.gov/cdf/cdf_home.html CDF lib. http://www.unidata.ucar.edu/packages/netcdf/ NetCDF lib. http://hdf.ncsa.uiuc.edu/ HDF lib. http://www.mesa3d.sourceforge.net Mesa3d lib. ftp.wizards.dupont.com/pub/ImageMagick/ ImageMagick Lib http://www.ibm.com/java/jdk/download/index.html Java Development Kit The installation examples will go into a nonstandard place, this is set by the configure option --prefix. CDF, netCDF, Magick, Mesa3d compiled and in non standard directories and require the configure options --includedir --libdir. The options --with-x --x-includes=/path/ --x-libraries=/path/ point to the Mesa3d libraries. Java explored J1.1.8 in non-standard place as well, and the $PATH variable points to the location. The configure option for java --with-jni-path has a few values, one to /J1.1.8, another to /J1.1.8/include and another to /J1.1.8/include/aix. The -with-java40-path points to the class.jar file usually in the netscape directory. Typing "configure --help" gives other possible changes. EXPLICIT EXAMPLE 1) gcc compiler and java configure --prefix=/u/res3/rpolson/OpenDX/DX4.0.10jx --with-x --x-includes=/u/res3/rpolson/OpenDX/include --x-libraries=/u/res3/rpolson/OpenDX/lib --includedir=/u/res3/rpolson/OpenDX/include --libdir=/u/res3/rpolson/OpenDX/lib --with-jni-path=/u/res3/rpolson/OpenDX/J1.1.8/:/u/res3/rpolson/OpenDX/J1.1.8/include:/u/res3/rpolson/OpenDX/J1.1.8/include/aix --with-java40jar-path=/tmp_mnt/home/aixlocal/ashare/libexec/netscape-4.61/java/classes/java40.jar After configure is completed two Makefiles have to be edited: /src/exec/dxexec/Makefile change line dxexec_LDADD = ../dpexec/libDPEXEC.a ../dxmods/libDXMODS.a ../libdx/libLIBDX.a ../hwrender/libHW.a ../hwrender/opengl/libOPENGL.a -L/usr/X11R6/lib -L/usr/local/lib -lm -lMesaGL -lX11 -lXext -l from -lGL to -lMesaGL TOC (table of contents) is too big. add flag -mno-fp-in-toc no change change : dxexec_LDFLAGS = -bE:$(EXP) to : dxexec_LDFLAGS = -Xlinker -bE:$(EXP) -Xlinker -bbigtoc -mno-fp-in-toc /src/uipp/dxui Makefile add flags -Xlinker -bbigtoc and -mno-fp-in-toc DEFS = -DHAVE_CONFIG_H -I. -I$(srcdir) -I../../../include CPPFLAGS = -mno-fp-in-toc -I/u/res3/rpolson/OpenDX/Mesa-3.0/include LDFLAGS = -Xlinker -bbigtoc -Xlinker -bexpall -mno-fp-in-toc make note: if in the middle of the make an error message that says something like "gcc not found" appears, this really means that a flag that is attempted to be passed to the linker has not been done properly. The likely fix is to go to the makefile in the directory where the make fails and look at lines LDFLAGS. For the gcc compiler to pass the flag properly it needs the additional flag "-Xlinker" added before the linker flag. make install change path to point to /installpath/dx/ make /installpath/bin/dx executable by "chmod 755 dx" edit /dx/bin/dx.workerscript and chmod 755 dx.workerscript make it executable # default to running locally, from /usr/lpp/dx set exhost=$thishost set dxroot=/u/res3/rpolson/OpenDX/dx set startup=1 # run the startup window by default change dxdata to /u/res3/rpolson/OpenDX/SamplesDX4.0/data change dx.workersxript line to: if (! $?dxdata) set dxdata="/u/res3/rpolson/OpenDX/SamplesDX4.0/data" EXPLICIT EXAMPLE 2) xlc compiler and java setenv CC xlc setenv CXX xlC (note capitalization difference) configure --prefix=/u/res3/rpolson/OpenDX/DX4.0.10xlcjx --with-x --x-includes=/u/res3/rpolson/OpenDX/include --x-libraries=/u/res3/rpolson/OpenDX/lib --includedir=/u/res3/rpolson/OpenDX/include --libdir=/u/res3/rpolson/OpenDX/lib --with-jni-path=/u/res3/rpolson/OpenDX/J1.1.8/:/u/res3/rpolson/OpenDX/J1.1.8/include:/u/res3/rpolson/OpenDX/J1.1.8/include/aix --with-java40jar-path=/tmp_mnt/home/aixlocal/ashare/libexec/netscape-4.61/java/classes/java40.jar /src/exec/dxexec/Makefile change -lGL to -lMesaGL make make install set path to point to /installpath/dx make /installpath/bin/dx executable by "chmod 755 dx" edit /dx/bin/dx.workerscript and chmod 755 dx.workerscript make it executable # default to running locally, from /usr/lpp/dx set exhost=$thishost set dxroot=/u/res3/rpolson/OpenDX/dx set startup=1 # run the startup window by default Good luck, Randy [EMAIL PROTECTED]
