prebuilt versions of ruby sometimes contain paths to nonstandard folders. need removing in $LDFLAGS
clang on osx masquerades as gcc need to test output of -v
WX uses 3 C++tr1 header versus C++11 header flags that need testing for to set (twice for 2 of them).

is it my problem when ruby with clang on osx is broken? (i currently havnt a osx machine to test it)
try to use a newer ruby/clang version that doesnt seems to break that much

also in your issue its difficult to read what changes i need to do,
can you make a clone, commits and a pull request so i can see what should be done?

[rinkevichjm]

I need to figure out how to make a pull request. I'm using Xcode 5 and the apple clang. On OS X wx uses clang directly while ruby uses gcc and "clang"!="gcc" however clang -v 2>&1 and gcc -v 2>&1 have matching lines as they are the same compiler.
And rvm installing some prebuilts binaries results in LDFLAGS having "-L/Users/xxxx/" which don't exist and cause the ld to error in building the bundle.

The changes now pass those tests some sort of issue with pkg_config of gtk files. Were you having problems with that? this should fix those too.

[rinkevichjm]

the correct test for clang with libc++ is

have_macro("_LIBCPP_VERSION","ciso646") # The C++ specification
specifically says that #include has no effect.

i added have_macro("_LIBCPP_VERSION","ciso646") for extra checking but i need to make the stdlib option optional because i cant check if wxwidgets is build against it or not, and if it isnt it will cause runtime errors.
i probably need to add an optional flag for c++11 too.

means i got 2 * 2 different configurations (and even more) because of yes/no libc++ and yes/no c++11
and i am totally unsure how the different settings are mixable.
(the gem and wx does want to be build against the same c++ lib and hopefully against the same c++XX version)

PS: you did compile wxwidgets and maybe ruby on purpose with libc++ and c++11 right? because without everything would be fine.

[rinkevichjm]

I have MAC OS X Yosemite so clang is built with libc++. I wish I knew what the build set up for that is. I look around as it may be a configure or cmake option.

Looking ing the mac ports port file for clang 3.6 suggests that setting the option --cxx_stdlib=libc++ will cause clang to be built with Libc++ as the default library, so you could configure build and install that. I'd think that if you could build a binary of that and just install the binary for tests that would be what is needed.

you still not know what i mean right?
i said that my rwx CANT KNOW (yet) if wxwidgets is build against libc++ or not

setting --cxx_stdlib=libc++ as default doesnt solve my problem

and the problem is if wxwidgets is build with libc++, not clang

[rinkevichjm]

But you need to be able to test with clang as is being built on OS X or FreeBSD. Where if --stdlib is not set libc++ is used. No?

No i mean i can build rwx with or without --stdlib, both of them does work

BUT if i start the program, AND wxwidgets does not have the SAME stdlib setting TOO

then it does crash.

means i need to check somehow what setting wxwidgets has

[rinkevichjm]

test have_macro "HAVE_TR1_TYPE_TRAITS","wx/setup.h" # if this exists you
don't have libc++

checking for "HAVE_TR1_TYPE_TRAITS" and "HAVE_TYPE_TRAITS" is not check enough for libc++ but for c++11 (libc++ can be build without c++11 too)

but HAVE_ABI_FORCEDUNWIND is something that does not exist on libc++ (i can use that for detecting libc++)

i added checks for both settings (and mixed), so it should work for your system now

[rinkevichjm]

checking for HAVE_TR1_TYPE_TRAITS in WX's setup.h is because WX's configure writes wx/setup.h, via auto configure test using the correct compiler setup. probably should flag an issue for wxwidgets team to fix configure to save -stdlib= flag from env CXXFLAGS for wx-config --cxxflags. The makefiles run with it but it but it isn't saved for wx-config

no, adding libc++ does not automaticlly enable c++11,
thats extra!

did you test it if that latest changes does works for you?
