[Gambas-user] Problem with PATH to shared library - part 2

[craf]

Hello. 

I forgot in the previous mail indicate the steps I have done: 

First run the command $ ldd gbr2 to see if there were dependency
problems, which I produced the following result: 

$ Ldd gbr2 
linux-gate.so.1 => (0xb770d000) 
libm.so.6 => / lib/tls/i686/cmov/libm.so.6 (0xb76db000) 
libdl.so.2 => / lib/tls/i686/cmov/libdl.so.2 (0xb76d7000) 
libpthread.so.0 => / lib/tls/i686/cmov/libpthread.so.0 (0xb76be000) 
libffi.so.5 => not found 
libc.so.6 => / lib/tls/i686/cmov/libc.so.6 (0xb756f000) 
/ Lib/ld-linux.so.2 (0xb770e000) 

This tells me they can not find the shared library libffi.so.5, for
which issued the command: 

$ Tree opt

This shows me that the library is located at: 

/opt/my_project/gambas2/library_shared/usr/lib 

Then try to add the path of the libraries in the ld.so.conf file,
leaving this way: 

include /etc/ ld.so.conf.d / *. conf 
/opt/my_project/gambas2/library_shared 

Save the changes to the file and then running: 

$ sudo ldconfig 

But I keep throwing the mistake of missing the library libffi.so.5 

Then I decide to modify the executable.sh, with the following: 

#! /bin/sh 
export PATH = / opt/my_project/gambas2/bin 
GB_DIR export = / opt/my_project/gambas2 
export LD_LIBRARY_PATH = / opt/my_project/gambas2/library_shared/lib: /
opt/my_project/gambas2/library_shared/usr/lib 
exec opt / my_project / my_project.gambas 

But now gives me the message "Segmentation fault"

any idea?
