building but not installing shared library...

[Ed Hartnett]

Howdy All!

I am the developer of netcdf, a free software tool for scientific data
storage.

I am using libtool 2.2 and am having a strange problem on an AIX
system.

When building a shared C library with gcc everything seems to
work. Here's the link:

libtool: link: ar cru .libs/libnetcdf2.a .libs/v2i.o
libtool: link: ranlib .libs/libnetcdf2.a
libtool: link: ( cd ".libs" && rm -f "libnetcdf2.la" && ln -s
"../libnetcdf2.la" "libnetcdf2.la" )
/bin/sh ../libtool --tag=CC   --mode=link gcc  -g -O2    -version-info
4:0:0   -o libnetcdf.la -rpath
/zasu/netcdf/n3_zasu/netcdf-3.6.3-snapshot2008051305/install1/lib\
 attr.lo ncx.lo putget.lo dim.lo error.lo libvers.lo nc.lo string.lo
 v1hpg.lo var.lo  posixio.lo libnetcdf2.la
libtool: link: /usr/bin/nm -B -BCpg  .libs/attr.o .libs/ncx.o
.libs/putget.o .libs/dim.o .libs/error.o .libs/libvers.o .libs/nc.o
.libs/string.o .libs/v1hpg.o .libs/va\
r.o .libs/posixio.o   ./.libs/libnetcdf2.a | awk '{ if ((($ 2 ==
"T") || ($ 2 == "D") || ($ 2 == "B")) && (substr($ 3,1,1) != ".")) {
print $ 3 } }' | sort -u > .libs/\
libnetcdf.exp
libtool: link: gcc -shared -o .libs/libnetcdf.so.4  .libs/attr.o
.libs/ncx.o .libs/putget.o .libs/dim.o .libs/error.o .libs/libvers.o
.libs/nc.o .libs/string.o .libs/v\
1hpg.o .libs/var.o .libs/posixio.o   ./.libs/libnetcdf2.a  -lc
-Wl,-bnoentry    -Wl,-bE:.libs/libnetcdf.exp -Wl,-berok
libtool: link: ar cru .libs/libnetcdf.a .libs/libnetcdf.so.4
libtool: link: ( cd ".libs" && rm -f "libnetcdf.la" && ln -s
"../libnetcdf.la" "libnetcdf.la" )


And so I get a file in the .libs directory libnetcdf.so.4 (but no
libnetcdf.so).

Later, when I run make install, only the static library is installed:

gmake[2]: Entering directory
`/zasu/netcdf/n3_zasu/netcdf-3.6.3-snapshot2008051305/libsrc'

----------------------------------------------------------------------
Libraries have been installed in:
   /zasu/netcdf/n3_zasu/netcdf-3.6.3-snapshot2008051305/install1/lib

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LIBPATH' environment variable
     during execution
   - use the
   
`-Wl,-blibpath:LIBDIR:/opt/gnu/bin/../lib/gcc-lib:/opt/gnu/gcc/lib/gcc-lib/powerpc-ibm-aix5.0.0.0/3.2:/opt/gnu/gcc/lib/gcc-lib/powerpc-ibm-aix5.0.0.0/3.2/\
../../..:/usr/lib:/lib ' linker flag

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

What's up here? Why does the .so.4 file get built, but never
installed?

Some other info about this platform:

bash$ ./libtool --features
host: powerpc-ibm-aix5.1.0.0
enable shared libraries
disable static libraries
bash$ gcc --version
gcc (GCC) 3.2

Any help would be appreciated.

Thanks!

Ed
