RELEASE NOTES
1. Patch SG0002312 Release Note
This release note describes patch SG0002312 to IRIX 6.2.
1.1 Supported Hardware Platforms
This patch contains bug fixes for all platforms. The
software cannot be installed on other configurations.
1.2 Supported Software Platforms
This patch contains the following bug fixes for the O32, N32
and 64-bit Fortran 77 runtime libraries. The patch is made
to install on a system running irix 6.2 with MIPSpro 6.2 or
7.1 compilers (or no compilers at all). The software cannot
be installed on other configurations.
1.3 Bugs Fixed by Patch SG0002312 1.3.1 Bugs Fixed in the O32 version of libftn.so
This patch contains fixes for the following bugs in the O32
version of the Fortran 77 runtime library for IRIX 6.2. Bug
numbers from Silicon Graphics bug tracking system are
included for reference.
o MAIN__ in libftn.so was defined as a strong symbol.
This would cause C or C++ programs linking with
libftn.so to get an rld error of the type:
26315:./a.out: rld: Error: unresolvable symbol in /usr/lib/libftn.so: MAIN__
if the programs required that LD_BIND_NOW be set. This
has been fixed (BUG ID #497568).
1.3.2 Bugs Fixed in the N32 and 64-bit versions of libftn.so
This patch contains fixes for the following bugs in the N32
and 64-bit Fortran 77 runtime libraries for IRIX 6.2. Bug
numbers from Silicon Graphics bug tracking system are
included for reference.
o Problems involving complex divide and complex
exponentiation in IRIX 6.2 (BUG ID's #367216, #382526).
o MAIN__ in libftn.so was defined as a strong symbol.
This would cause C or C++ programs linking with
libftn.so to get an rld error of the type:
26315:./a.out: rld: Error: unresolvable symbol in /usr/lib/libftn.so: MAIN__
if the programs required that LD_BIND_NOW be set. This
has been fixed (BUG ID #497568).
o Programs that used variable format statements would
core dump. For example the following program would
produce a segmentation violation when compiled -n32 or
-64:
program main
k = ival('hell')
print *, k
stop
end
INTEGER*4 FUNCTION IVAL(str)
CHARACTER*(*) str
CALL STRFIX(str,I1,K)
read(str(1:k),1000,ERR=30) IVAL
1000 FORMAT (i<K>)
30 continue
RETURN
END
SUBROUTINE STRFIX(STR,I1,I2)
CHARACTER*(*) STR
i1 = 1
i2 = 4
RETURN
END
This has been fixed (BUG ID #385188).
1.4 Subsystems Included in Patch SG0002312
This patch replaces patch 1378 and patch 1630. It is
incompatible with patch 2016 or 2483 which require MIPSpro
7.2 compilers.
This patch release includes these subsystems:
o patchSG0002312.ftn77_eoe.lib
o patchSG0002312.ftn_eoe_sw64.lib
o patchSG0002312.ftn77_eoe.sw32.lib
1.5 Installation Instructions
Because you want to install only the patches for problems
you have encountered, patch software is not installed by
default. After reading the descriptions of the bugs fixed
in this patch (see Section 1.3), determine the patches that
meet your specific needs.
If, after reading Sections 1.1 and 1.2 of these release
notes, you are unsure whether your hardware and software
meet the requirements for installing a particular patch, run
inst. The inst program does not allow you to install
patches that are incompatible with your hardware or
software.
Patch software is installed like any other Silicon Graphics
software product. Follow the instructions in your Software
Installation Administrator's Guide to bring up the miniroot
form of the software installation tools.
Follow these steps to select a patch for installation:
1. At the Inst> prompt, type
install patchSGxxxxxxx
where xxxxxxx is the patch number.
2. Initiate the installation sequence. Type
Inst> go
3. You may find that two patches have been marked as
incompatible. (The installation tools reject an
installation request if an incompatibility is
detected.) If this occurs, you must deselect one of
the patches.
Inst> keep patchSGxxxxxxx
where xxxxxxx is the patch number.
4. After completing the installation process, exit the
inst program by typing
Inst> quit
1.6 Patch Removal Instructions
To remove a patch, use the versions remove command as you
would for any other software subsystem. The removal process
reinstates the original version of software unless you have
specifically removed the patch history from your system.
versions remove patchSGxxxxxxx
where xxxxxxx is the patch number.
To keep a patch but increase your disk space, use the
versions removehist command to remove the patch history.
versions removehist patchSGxxxxxxx
where xxxxxxx is the patch number.
1.7 Known Problems INST SUBSYSTEM REQUIREMENTS No Requirements Information Available. INST SUBSYSTEM CHECKSUMS These checksums help to provide a 'signature' for the patch inst image which can be used to authenticate other inst images. You can obtain this kind of output by running sum -r on the image (from the command line): 36877 4 patchSG0002312 47669 598 patchSG0002312.ftn77_eoe 00476 1918 patchSG0002312.ftn77_eoe_sw32 06594 2011 patchSG0002312.ftn77_eoe_sw64 39089 3 patchSG0002312.idb INST SUBSYSTEM FILE LISTINGS The following lists the files which get installed from each subsystem in the patch:
