I have downloaded Dia from QNX repository and when I type “dia” then this is the result :
** WARNING **: Could not determine the local charset. Using ISO-8859-1 by default.
This failure may be caused by an incorrect compilation.
Memory fault (core dumped)
I think cdm compiled the “dia” on the 3rd party repository, and he may be able to give help.
In the meantime, can you try:
export LC_ALL=C
before starting “dia” ?
