GT 0063 Emulation Enhancements
1. EPOCROOT check in E32env.PM
Changed from static data to an active BEGIN{} section which tests the EPOCROOT
environment variable and constructs the rest of the E32env::Data hash accordingly.
EPOCROOT checking is:
- environment variable must exist
- EPOCROOT must begin with \
- EPOCROOT must specify an existing directory
Most clients are expected to use $E32Env::Data{EPOCPath} as the raw "epoc32" directory.
2. Path_MakeEAbs in PATHUTL.PM
Variant of Path_MakeAbs.
Path_MakeEAbs takes (EPOCPath, BasePath, ...) and makes the list of directories into
absolute paths relative to BasePath. The extra functionality is that paths beginning
+\...
are treated as paths relative to EPOCPath rather than BasePath.
As a regression change, this change also extends to paths which begin \epoc32\, which
copes with the large number of existing absolute \epoc32 paths (e.g. SYSTEMINCLUDE
statements in MMP files).
Path_MakeEAbs is used in MMP.PM to handle SYSTEMINCLUDE, DEFFILE and USERINCLUDE
statements, and in BLDMAKE.PL to handle PRJ_EXPORTS and PRJ_TESTEXPORTS.
