mac-o symbols are prefixed with an underscore. when specifying multiple
sub-regexes (e.g. 'sym1|sym2|sym3'), only the first will be matched
(since the expansion turns into '(?P<symbol>_?sym1|sym2|sym3)'). here,
this is remedied by wrapping the symbol regex in a paren group.
The global value gccdeps was appended to CFLAGS and CXXFLAGS instead of
the actual flags tested against the compiler. This ignored
modifications to the GCCDEPS_FLAGS environment variable and complicated
adding support for additional compilers at the project level.
previously code was erroneously using tg.bld.path instead of tg.path
so for nested wscript calls the wrong directory was used in search.
added also better error handling with error message if an included
directory does not exist
When CDT is not included in the project (ie. we just have Python and/or Java) the current implementation would not create automatically a call to waf
for the build stage. This patch adds in such cases an external builder that automates the call to waf without the need to manually configure one.
added support to search and add into source path also generated source
files for both java and python. this is useful when using generated code
(ie. protoc and pyqt5) so browsing in eclipse works correclty adding also
paths where generated code is done.
extended example in playground demostrating generated code
If any weights (i.e. `weight` or `tree_weight`) are set on a swig task
then those weights are passed on to the task created to compile the
wrapper generated by swig.
The previous logic in #1709 made an incorrect assumption that the
filename of shared/static library indicates that it was build as
multi-threaded or single threaded. This assumption does not hold in many
Linux distributions.
In addition to that. Boost.Thread and Boost.Log require -pthread (or
some other) flags in order to properly link.
When shared library compiled with precompiled headers enabled, this
change prevents precompiled headers to activate on dependent targets.
Otherwise, there is an issue with -fPIC flag propagation.
