version major.minor [explicit]

-

The version keyword allows a version number to be set -for a project. The optional keyword, explicit is used to -append the specified version number to the .exe or .dll output -file.

-

EKA1 will only allow one version of an executable to exist in a Symbian -platform phone. However, EKA2 supports version numbering. Version numbering -associates a version number with each executable enabling new and old versions -of the same executable to be on the device simultaneously.

-

The version keyword takes a major and a minor value separated -by a full stop. This value is defined as 32 bit, anything exceeding this will -produce a warning. Failing to enter a value will result in a warning and a -default value of 10.0 being supplied for binaries built with an EABI compliant -compiler. Omitting the version keyword altogether will also result in a default -of 10.0 being applied. The version number can be found at Hexadecimal offset -70 within the header of the executable file in ROM.

-

Usage of the version keyword is optional. One use is to aid eclipsing. -In order to eclipse a file on ROM successfully the version of the new file -can be set to a higher value than the version of the file to eclipse. This -tells the loader that the new file is preferred over the old one.

-

See the Important -Considerations section for more information.

-

The loader will show preference to versions that have a major number that -is equal to the one requested, and of these the minor numbers -that are higher are preferred. The loader can assume by the version number -that the API is compatible, while also being the most up to date version available.

-

If the above is not available the loader will look for DLLs with a higher -major version number than the one requested. Of these it will select the one -with the lowest major number and the highest minor number. If the executable -requests exports that no longer exist in this DLL, then the loader cannot -use it.
