Hi,
problem: I want to start a software WITHOUT the environment is set -
this include LD_LIBRARY_PATH
(HELP: the '...' down in the text are from me to shorten the output)
> ./cct
couldn't load file ".../libtclreadline.so": libreadline.so.4.0: cannot
open shared object file: No such file or directory
analyze:
> ls -al .../libtclreadline.so
lrwxrwxrwx 1 dev1usr users 23 10. Mai 09:39 .../libtclreadline.so ->
libtclreadline-3.0.0.so
The file is available BUT point with as SOFT-LINK to LOCAL file
-> seems that -rpath . (local directory is NOT available)
-> seems that WITHOUT local directory in LD_LIBRARY_PATH the softlink
(from automake) seems NOT to work
---------------------------------
solution #1, setup LD_LIBRARY_PATH after software cct has started
adding LD_LIBRARY_PATH after cct was started does NOT help because
'ld.so' seems to use the LD_LIBRARY_PATH before
cct was started.
-> HOW I tell 'ld.so' to accept a new LD_LIBRARY_PATH after start from cct ?
-----------------------------
stepping deeper I start to analyze the build of libtclreadline, an
automake software
I install the "automake" software tclreadline with the following build-plan:
#1 tclreadline source build and install into staging-area
#2 staging-area tested and verified, finally copied into destination-area
with: staging-area != destination-area
problem: The '-rpath' from the 'staging-area' does not fit into the
'destination-area'
TRY for solution:
#1 add line 'libtclreadline_la_LDFLAGS = -release
$(MAJOR).$(MINOR).$(PATCHLEVEL) -rpath .../lib' to Makefile.am
# output
/bin/sh ./libtool --tag=CC --mode=link gcc -m32 -O2 -g -O2 -release
3.0.0 -rpath .../linuxi386/lib -o libtclreadline.la -rpath
.../var/pkg/install/TclRl_3_0/lib tclreadline.lo -lncurses -L...
-lreadline
libtool: warning: ignoring multiple '-rpath's for a libtool library
staging area : -rpath .../var/pkg/install/TclRl_3_0/lib
destination-area : -rpath .../linuxi386/lib
#1 As you see NO multiple -rpath are NOT allowed
#2 Same for '-rpath .' local directory is not allowed at all !!
conclusion:
#1 I can NOT set the LD_LIBRARY_PATH after start (preferred solution)
#2 I can NOT set the right -rpath to the automake created library
question
#1 what to do?
#1 tclreadline is just an example other automake software likely have
the same problem.
I prefer NO solution where I have to modify ALL Makefile.am files
because of the
-rpath problem.
