hallo,
i want to write a console program to convert dwg/dwf to pdf. i have found the following code in the forum and changed it a little bit.
but when i start the program i have always a segmentation fault.

what is wrong ??? !!!!!
have you tried 2.7.0 available at
?
sergey slezkin
... hm ... linux ... ???? !!!!!
sorry..
some problems in pdf export on linux were fixed before 2.6.3 release.
but a bug in oddbfontservices::loadstylerec () was fixed just before 2.7.0 (it's not linux specific).
sergey slezkin
ok,
i work with 2.6.3. is the problem in my sourcecode or ??? !!!
i have not not found a complete example for pdf export.
can anyone help !!!!
hallo,
i have found the error for my self. do not define a odstring findfile(...) function in myservices class and all works perfectly.
this helps not in all situations. loadstylerec() contains a bug which may cause the same error (but not always). the linux release with the fix is expected in the middle of january.
