IOAPI 3.0 - 17 Mar 2006 The I/O API Version 3.0 source code, documentation, and binary object libraries for certain platforms are available at: http://www.baronams.com/products/ioapi/AVAIL.html This web site shows how to build IOAPI libraries in detail. The following is a summary: 1) Untar the downloaded file: tar xvfz ioapi-3.0.tar.gz 2) Determine your machine architecture and the available Fortran and C compilers: The command "uname -a" provides machine architecture information. 3) Go to the ioapi subdirectory and determine the supported architecture and compilers: ls -al Makeinclude.* The Makeinclude file extensions are named according to the type of architecture and compiler. For instance, if your machine is a Linux box with Pentium processor and you are using an Portland Group Fortran compiler (pgf90), you should use Makeinclude.Linux2_x86pg. 4) Set up the library directory: setenv BIN where is the file extension you determined in step #3. Using the previous example, you would type: setenv BIN Linux2_x86pg 5) Select the no-couple Makefile: cp Makefile.nocpl Makefile You may need to edit the Makefile to set the location for BASEDIR. 6) Build the library by typing: make Note: 1. If the compilers you chose are not found, check Makeinclude. to see whether the compiler paths are set correctly. 2. In our compilation, we used pgf90 and gcc. We made the following changes to the Makeinclude.Linux2_x86pg file ("patch" style difference): 25c25,26 < CC = pgcc --- > #CC = pgcc > CC = /usr/bin/gcc 33c34,35 < OMPFLAGS = -mp --- > #OMPFLAGS = -mp > OMPFLAGS = 35,36c37,40 < COPTFLAGS = -O2 ${MFLAGS} < FOPTFLAGS = -O2 ${MFLAGS} --- > #COPTFLAGS = -O2 ${MFLAGS} > COPTFLAGS = -O2 -ffast-math -DIOAPI_NO_STDOUT > #FOPTFLAGS = -O2 ${MFLAGS} > FOPTFLAGS = -O2 -fast -DIOAPI_NO_STDOUT 38c42,43 < FSFLAGS = --Msave --- > #FSFLAGS = --Msave > FSFLAGS = -Bstatic Note: You can change the file by using the Unix "patch" utility. Cut the indented section listed above and paste into a file, say "mod." Then type "patch
