If the library is located in '/opt/my_project/gambas2/library_shared/usr/lib',
why do you write '/opt/my_project/gambas2/library_shared' only?

The syntax is not correct, you should have no spaces inside the path, and
around the equal sign.
> GB_DIR export = / opt/my_project/gambas2
The syntax of this line is not correct too. 'export' must come first.
> export LD_LIBRARY_PATH = / opt/my_project/gambas2/library_shared/lib: /

same remark with spaces.
> exec opt / my_project / my_project.gambas
same remark with spaces.

Nope. But fix all the previous errors and try again!
