# 9.4. Linker Options

The Linker Options for your current project can be set by the last page of the project options dialog. You have to enable those libraries that your application uses to link them to your binary with the Linker , e.g. your application uses the class KFileDialog. As the class KFileDialog is part of the KFile library, you have to enable kfile. For classes or functions that are not listed as checkboxes, use the "additional libraries" field.

## 9.4.1. Linker Flags

remove all symbol table and relocation information from the executable:

  This means that all redundant information will be removed from the object files and the binary, resulting that debugging will not be possible. For as long as your application is in a development stage and not released as final, you should leave this option disabled.

prevent using shared libraries:

  This option disables the use of shared libraries on systems that support this. On systems using no shared libraries, this option will have no effect.

additional flags:

  Here, you can enter additional flags for the Linker , setting the LDFLAGS environment variable by make . The available options can be taken from the man page for ld or your Compiler manpage.

## 9.4.2. Libraries

The libraries section contains checkboxes for the most needed libraries in conjuction with Qt/KDE application development. You have to enable those libraries that your application uses, otherwise the Linker will complain about unresolved symbol tables.
