working with cpp on mac?

[lewislepton]

im having troubles getting this working with heaps on mac.

building to html works fine. but once it comes to cpp it does spit out trouble.

i have the setup of putting glext.h inside the SDL2 [sdk download] include folder. but am getting nothing. still more errors

Error: In file included from ./src/sdl/Sdl.cpp:10:
In file included from include/sdl/Sdl.h:10:
/usr/local/lib/haxelib/hxsdl/git/SDLSupport.h:11:10: fatal error: 'GL/GLU.h' file not found
#include <GL/GLU.h>

[lewislepton]

just help with hopefully some screenshots would be great ;)

I don't have an OSX to test on here, but I've commit a fix, tell me how it works

[ncannasse]

My bad, try again

[lewislepton]

hmmmm. this is the output

Error: Build failed

also this is what my hxsdl looks like. just to make it easier ;)

also where the glext is, which is inside the SDL2 folder

[ncannasse]

One more try? :)

[lewislepton]

ha. it built quite a bit more this time. but then came up with some other errors

here is the last portion which has the errors

this is the first part which has some warnings

Right, SDL linking is missing, could you try again?

[lewislepton]

just tried and it seemed to have. but said about SDL missing

ld: framework not found SDL2

[lewislepton]

though am sure i have installed it in hxsdl. plus do have it in my local frameworks folder

[lewislepton]

the pictures i posted before show the layout of the hxsdl setup

[ncannasse]

Could you check replacing SDL2 by SDL in native.xml ?

[lewislepton]

hmmm. same thing. says that it is not found

[ncannasse]

@hughsando any insight? PS: I'm using the following config file https://github.com/ncannasse/hxsdl/blob/master/native.xml

[hughsando]

I guess checking the link line to make sure it has the flags you want. Also, do you need to install the sdl2 framework somehow on mac - third party installer? FYI, there is also a similar project https://github.com/snowkit/linc_sdl

[lewislepton]

i do have sdl instaled in my framework folder. did just try another time that im back from work, but again, not working

[ncannasse]

linc_sdl directly compiles the SDL sources, whereas hxsdl usually uses the precompiled shared library. @lewislepton it seems that you need the SDL library actually installed to be used in OSX toolchain, not sure exactly how to do that.

Look at https://developer.apple.com/library/mac/documentation/MacOSX/Conceptual/BPFrameworks/Tasks/InstallingFrameworks.html

[lewislepton]

normally in mac-land. to install SDL [or any packed framework], you just need to plop SDL2, into your global frameworks folder. so it affects everything no matter what user. which actually, the link you gave is just that

but SDL installing is probably the fifth thing i do when i either do a clean install or on a new mac computer ;)
