* You currently need GNU make to build the Libtool package itself.
|
|
|
|
* On AIX there are two different styles of shared linking, one in
|
|
which symbols are bound at link-time and one in which symbols are
|
|
bound at runtime only, similar to ELF. In case of doubt use
|
|
`LDFLAGS=-Wl,-brtl' for the latter style.
|
|
|
|
* On AIX, native tools are to be preferred over binutils; especially
|
|
for C++ code, if using the AIX Toolbox GCC 4.0 and binutils,
|
|
configure with `AR=/usr/bin/ar LD=/usr/bin/ld NM='/usr/bin/nm -B''.
|
|
|
|
* On AIX, the `/bin/sh' is very slow due to its inefficient handling
|
|
of here-documents. A modern shell is preferable:
|
|
CONFIG_SHELL=/bin/bash; export $CONFIG_SHELL
|
|
$CONFIG_SHELL ./configure [...]
|
|
|
|
* For C++ code with templates, it may be necessary to specify the
|
|
way the compiler will generate the instantiations. For Portland
|
|
pgCC version5, use `CXX='pgCC --one_instantiation_per_object'' and
|
|
avoid parallel `make'.
|
|
|
|
* On Darwin, for C++ code with templates you need two level shared
|
|
libraries. Libtool builds these by default if
|
|
`MACOSX_DEPLOYMENT_TARGET' is set to 10.3 or later at `configure'
|
|
time. See `rdar://problem/4135857' for more information on this
|
|
issue.
|
|
|
|
* The default shell on UNICOS 9, a ksh 88e variant, is too buggy to
|
|
correctly execute the libtool script. Users are advised to
|
|
install a modern shell such as GNU bash.
|
|
|
|
* Some HP-UX `sed' programs are horribly broken, and cannot handle
|
|
libtool's requirements, so users may report unusual problems.
|
|
There is no workaround except to install a working `sed' (such as
|
|
GNU sed) on these systems.
|
|
|
|
* The vendor-distributed NCR MP-RAS `cc' programs emits copyright on
|
|
standard error that confuse tests on size of `conftest.err'. The
|
|
workaround is to specify `CC' when run configure with `CC='cc
|
|
-Hnocopyr''.
|
|
|
|
* Any earlier DG/UX system with ELF executables, such as R3.10 or
|
|
R4.10, is also likely to work, but hasn't been explicitly tested.
|
|
|
|
* On Reliant Unix libtool has only been tested with the Siemens
|
|
C-compiler and an old version of `gcc' provided by Marco Walther.
|
|
|
|
* `libtool.m4', `ltdl.m4' and the `configure.ac' files are marked to
|
|
use autoconf-mode, which is distributed with GNU Emacs 21,
|
|
Autoconf itself, and all recent releases of XEmacs.
|
|
|
|
* When building on some linux systems for multilib targets `libtool'
|
|
sometimes guesses the wrong paths that the linker and dynamic
|
|
linker search by default. If this occurs, you may override
|
|
libtool's guesses at `configure' time by setting the `autoconf'
|
|
cache variables `lt_cv_sys_lib_search_path_spec' and
|
|
`lt_cv_sys_lib_dlsearch_path_spec' respectively to the correct
|
|
search paths.
