- Versioning of Shared Objects.
-
- QUICK OVERVIEW
-
- For a shared object to be versioned
- the following needs to be done:
-
- * Version strings consist of 3 parts and a dot: The string "sgi",
- a decimal number (the major number), a dot, and a decimal number
- (the minor number).
-
- * Add the command -set_version sgi1.0 to the command to build
- the shared object (cc -shared, ld -shared, etc.).
-
- * Whenever you make a COMPATIBLE change update the minor version
- number (the one after the dot), and add the latest version string
- to colon-separated list of version strings, e.g., -set_version
- sgi1.0:sgi1.1:sgi1.3
-
- * Whenever you make an INCOMPATIBLE change, update the
- major version number. Pass this as the version list, e.g.,
- -set_version sgi2.0. Change the filename of the OLD shared object
- by adding a dot followed by the previous major number to the filename
- of the shared object. DO NOT CHANGE the soname of the object.
- No change to the file contents are necessary or desirable. Simply
- rename the file.

-Through installing the plotutils package on several platforms, I've turned
-up a few additional bugs in libtool-1.2. Here they are...
-
-1. The plotutils package uses libtool to link together a shared library,
-`libplot'. It also compiles several executables, each in its own
-subdirectory, and links them with `libplot'. It then runs tests on the
-executables.
-
-By looking at the test output I figured out that the version of libplot
-that gets linked with the executables is by default the previously
-installed version (if any), rather than the one that that's just been
-built. This happens under IRIX 5.3 and 6.4, when compiling with both cc
-and gcc. Probably on other platforms as well.
-
-I assume there's something wrong with LD_LIBRARY_PATH. But the shell
-scripts that libtool generates (i.e., the pseudo-executables) contain the
-lines
-
- # Add our own library path to LD_LIBRARY_PATH
- LD_LIBRARY_PATH="$thisdir/../libplot/.libs:$LD_LIBRARY_PATH"
-
- # Some systems cannot cope with colon-terminated LD_LIBRARY_PATH
- LD_LIBRARY_PATH=`$echo "X$LD_LIBRARY_PATH" | $Xsed -e 's/:*$//'`
-
-which certainly look right.
-
-A workaround here is to do `rm -f /usr/local/lib/libplot.*' before
-installing the package. But that's a pretty drastic workaround.
-
-2. At least on those IRIX platforms, there's something buggy about the
-option "-set_version 1.1.2:0.0:1.0" that libtool-1.2 passes to ld. If
-I compile a version of my `graph' utility that is meant to be linked with
--lXm instead of -lXaw (the default), as well as -lplot, I get the following
-when I go to its subdirectory and try to run it without installing it:
-
- cosmo$ echo 0 0 1 1 2 0 | graph -TX -C
- 4352:graph: rld: Warning: version search suppressed because object libplot.so in liblist has non-sgi interface version (1.0)
- 4352:graph: rld: Fatal Error: cannot map soname 'libplot.so' using any of the filenames /usr/local/lib/libplot.so:/lib/libplot.so:/usr/lib/libplot.so:/usr/local/ivtools/lib/SGI/libplot.so:/lib/cmplrs/cc/libplot.so:/usr/lib/cmplrs/cc/libplot.so: -- either the file does not exist or the file is not mappable (with reason indicated in previous msg)
-
-Not sure what's going on here. If I do a `make install', the installed
-version of `graph' functions perfectly. It's only the uninstalled one,
-built specially to be linked with -lXm, that gives error messages about SGI
-version numbering for -lplot.
