|
13 to use the post-linker (elf2e32)</title><prolog><metadata><keywords/></metadata></prolog><conbody> |
|
14 <p>The post-linker is a Symbian-specific build tool. Its principal function |
|
15 is to create executables (DLLs and EXEs) in the particular format required |
|
16 by Symbian platform, known as the <i>E32Image</i> format. Commercial compiler |
|
17 and linkers, such as ARM's RVCT and GNU GCC, cannot directly generate that |
|
18 format. Such compilers do however support a standard output format called |
|
19 the Executable and Linking Format (ELF) (defined at <xref href="http://www.caldera.com/developers/gabi/" scope="external">http://www.caldera.com/developers/gabi/</xref>). A tool is |
|
20 therefore needed to convert from the ELF format into the E32Image format, |
|
21 and this is the key role of the post-linker. The tool also contains the functionality |
|
22 to maintain and create the DEF files used for freezing the exports of libraries. </p> |
|
23 <p>In ordinary use, the post-linker is not used directly by users. It is called |
|
24 from the makefiles generated by <filepath>abld</filepath> on the command line, |
|
25 or from the build commands of an IDE. </p> |
|
26 <p>The tool can also be used to <xref href="GUID-6A5D3E05-B1F4-4DF6-9384-3CC471DCC267.dita">output |
