Fix: Install GCC and C++ support
$ sudo yum install gcc
$ sudo yum install gcc-c++
4) Unable to execute projects inside AbsoftTools
Symptom:
An error dialog appears which reads "Could not start "xterm -name "Absoft Tools"... "
Fix: install xterm program

Symptom:
$ af90 t.f
sh: /opt/absoft11.5/bin/af90fe64: /lib/ld-linux.so.2: bad ELF interpreter:
No such file or directory
f90fe failed.
Fix: Install 32 bit executable support
$ sudo yum install glibc.i686
2) atmod fails, missing 32 bit libstdc++.so.6
Symptom:
$ af90 t.f
/opt/absoft11.5/bin/atmod: error while loading shared libraries:
libstdc++.so.6: cannot open shared object file:
No such file or directory
Fix: Install 32 bit libstdc++.so.6
$ sudo yum install libstdc++.i686
3) Unable to execute projects inside AbsoftTools
Symptom:
An error dialog appears which reads "Could not start "xterm -name "Absoft Tools"... "
Fix: install xterm program
$ sudo yum install xterm
4) Unable to build 32 bit programs
Symptom:
$ af90 -m32 t.f
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: skipping incompatible /usr/lib64/libpthread.so when
searching for -lpthread
Fix: install 32 bit development libraries
$ sudo yum install glibc-devel.i686
Open SuSE 12.1 64 bit
A default installation of Open SuSE 12.1 requires the following additional software to fully support Absoft Fortran 2012:
Package Description
---------------------- ---------------------------------------
gcc Support for software development
gcc-c++ Support for software development
gcc-32bit Support for building 32 bit programs
gcc-c++-32bit Support for building 32 bit programs
Examples below give a possible error messages reported when a package is missing and the zypper command to install the package.
1) Link fails, g++ not found
Symptom:
$ af90 t.f
sh: g++: command not found
link failed.
Fix: install g++ (along with the rest of the C development tools)
$ sudo zypper install gcc-c++
Explanation:
We use g++ to perform the link because AWE is written in C++.
2) Unable to build 32 bit programs
Symptom:
$ af90 -m32 t.f
