|
# Notes on this toolset:
|
|
#
|
|
# - Because of very subtle issues with the default ansi mode, strict_ansi mode
|
|
# is used for compilation. One example of things that don't work correctly in
|
|
# the default ansi mode is overload resolution of function templates when
|
|
# mixed with non-template functions.
|
|
#
|
|
# - For template instantiation "-timplicit_local" is used. Previously,
|
|
# "-tlocal" has been tried to avoid the need for a template repository
|
|
# but this doesn't work with manually instantiated templates. "-tweak"
|
|
# has not been used to avoid the stream of warning messages issued by
|
|
# ar or ld when creating a library or linking an application.
|
|
#
|
|
# - Debug symbols are generated with "-g3", as this works both in debug and
|
|
# release mode. When compiling C++ code without optimization, we additionally
|
|
# use "-gall", which generates full symbol table information for all classes,
|
|
# structs, and unions. As this turns off optimization, it can't be used when
|
|
# optimization is needed.
