#33 ./hwgdebug: error while loading shared libraries: libharbour.so.3.4

[domenico d'oria]

hi to all and happy new year

today after some weeks, i try to recompile my programs on ubuntu 20.04.1 lts
before i git-pull harbour 3.2 and run make clean install, all works well
regenerate hwgui lib from source and libs correctly appear on lib directory

but i do not update hwgui lib from svn

i recompile with standard hbmk2 project.hbp

the project.hbp have -b flag

the compilation works

but when i run the executable i receive this :
./hwgdebug: error while loading shared libraries: libharbour.so.3.4: cannot open shared object file: No such file or directory

clearly i do not use harbour 3.4

so whats i'm doing wrong ?

if i try to recompile whithout -b flag all works

regards

domenico

Hello Domenico,
i tried to retrace the case on my Ubuntu 16.04 system, but i realized the
following:
With the -b option in logw.hbp the app does not start, it is running dead.
I used forever the code snapshot of Harbour and HWGUI.
But i prefer a static build of my app, i think it avoids errors for the
user.
I build the product in the regular order:
1.) Harbout 2.) HWGUI 3.) CLLOG
and i have no trouble.

My hbp file is here:
https://sourceforge.net/p/cllog/code/HEAD/tree/trunk/src/logw.hbp

Here some query output's of the userid running my app "CLLOG":

~/Harbour/core-master/lib/linux/gcc$ ls libharbour.*
libharbour.so libharbour.so.3.2 libharbour.so.3.2.0

cat ~/.profile
...

==> the exported environment variable "LD_LIBRARY_PATH" is a search path setting
for libraries.

The command "ldd" displays all libraries loaded for program start

ldd ./logw

A trick could be, to set a symbolic link from an existing library to the requiered one:

~/Harbour/core-master/lib/linux/gcc$ ln -s libharbour.so.3.2 libharbour.so.3.4

ls -l libharbour.so*
lrwxrwxrwx 1 cltest cltest 19 Aug 8 11:31 libharbour.so -> libharbour.so.3.2.0
lrwxrwxrwx 1 cltest cltest 19 Aug 8 11:31 libharbour.so.3.2 -> libharbour.so.3.2.0
-rwxrwxr-x 1 cltest cltest 5624176 Aug 8 11:31 libharbour.so.3.2.0
lrwxrwxrwx 1 cltest cltest 17 Jan 4 10:46 libharbour.so.3.4 -> libharbour.so.3.2

I hope, this helps you.

A happy new year,
