Hello,
I am using libtool 2.2.6, autoconf 2.63 and automake 1.10.1 . I want to
write plugins for a programme, that are dlpreopen-ed. I achived this by
putting
pkglib_LTLIBRARIES = plugin1.la, plugin2.la
in Makefile.am . In consequence plugin1 and plugin2 get installed. Since
the modules are dlpreopened, my application works perfectly without
accessing the the installed plugins. Therefore I want to NOT install the
libraries. To achieve this, I replaced in Makefile.am the above line with
noinst_LTLIBRARIES = plugin1.la, plugin2.la
and autoreconf-ed. However, now libtool reports during make-ing:
make all-am
make[1]: Entering directory `/root/proj/mailing-lists-sieve'
/bin/bash ./libtool --tag=CC --mode=link gcc -Wall -Wextra -O3
-march=native -export-dynamic -lglib-2.0 -o src/mailing-lists-sieve
src_mailing_lists_sieve-generators.o -dlpreopen src/generators/sample.la
-lltdl
libtool: link: only libraries may -dlpreopen a convenience library:
`src/generators/sample.la'
make[1]: *** [src/mailing-lists-sieve] Error 1
make[1]: Leaving directory `/root/proj/mailing-lists-sieve'
make: *** [all] Error 2
* How would you recommend to both dlpreopen the libraries, and not
install them with `make install`? As a side note, my programm does not
come with its own copy of libltdl, it requires it to be presented on the
host system (configure.ac AC_LIBTOOL_DLOPEN LT_INIT([disable-shared,
dlopen])
In regards the documentation of libtool 2.2.6, in Section Dlopened
Modules, Chapter Dlpreopening some internals are mentioned
-- Structure: struct lt_dlsymbol { const char *NAME; void *ADDRESS; }
-- Structure: struct lt_dlsymlist { const char *ORIGINATOR;
const lt_dlsymbol SYMBOLS[]; }
-- Variable: const lt_dlsymlist * lt_preloaded_symbols
An array of LT_SYMBOL structures, representing all the preloaded
* ltdl.h has no definition for lt_dlsymbol, since libtool 1.9d, perhaps
it shall disappear from the documentation, too.
* "LT_SYMBOL" strucres is nowhere else mentioned and defined. Perhaps
you meant "array of struct lt_dlsymlist"?
* Moreover, include/ltdl.h defines that structure lt_dlsymlist with
typedef struct {
const char *name;
void *address;
} lt_dlsymlist;
, where "name" and "address" are not capitalized, in contrary to the
documentation.
Thanks in advance for your feedback,
