getch() equivalent on osx?

[smartalco]

what is the equivalent of getch() on osx? if there is one

note: if anyone knows of a resource that lists osx equivalents of commonly used windows functions and system calls i would really like the url

[PowerMacX]

A starting point:
http://developer.apple.com/documentation/Porting/Conceptual/win32porting/win32porting.html

Mac OS X has getch, though whether it's the same as the windows one or not, I don't know.
man getch

[smartalco]

found that^, used it, and i got two different errors depending on if i allow zerolinking or not

if i allow zerolinking i get the error "ZeroLink: unknown symbol '_stdscr'" when i run it, if i disable zerolinking i get an error while building saying "Undefined ymbols:"

the error has something to do with the curses.h header that getch() is in, when i comment out that header and replace getch() with cin just to test it builds and runs fine

little help?


side problem: im also using system("clear"); in the same program and when running it says "TERM environment variable not set.", what do i need for that to work properly

Under your build rules, add "-lcurses" to your additional linker flags. (basically, you need to link the library before you can actually use it)

[OneSadCookie]

not -lncurses?

to get TERM set properly, run it from the terminal, instead of from Xcode.

[akb825]

Or that one. :p

[smartalco]

i added -lcurses to "other linker flags" (im assuming its the same thing) and i still get the same error if i have zeroLink enabled and it opens the dubugger when i run if i have zeroLink disabled :/

edit: i changed it to -lncurses and it does the same thing...

[akb825]

Are you sure that it's set in your current build setting? (it would actually be best if you entered it when set to all build settings)

[smartalco]

^i think so... i went to SCM -> configure SCM, clicked on the "Build" tab, found the "Other Linker Flags" setting and added "-lncurses"

would i have to add something for other headers i included? (theres iostream, string, and curses.h)

[OneSadCookie]

SCM stands for source code management (CVS, SVN, etc.) so it doesn't sound like the right place. Find your target in the left column, and get info on that.

[smartalco]

heres a screenshot of the specific error (i think) if any of you have the knowledge to understand what it means

i added curses.h (header getch() is in) to the "Link Binary With Libraries" folder, it just added it to my source files, i ctrl-clicked on "Targets" and clicked "Get Info" and it brings up a box saying "Nothing to inspect", same thing on "Link Binary With Libraries" and it brings up a comment box, same thing again on the pong folder under targets and it brought up a window very similar to the "Configure SCM" window, i checked the "other linker flags" property and -lncurses was already listed there, i then found 3 similar properties "Additional Strip Flags", "Other C Flags", and "Other C++ Flags" and added -lncurses to all of those, still same problem..

P.S. sorry if im giving too many details, just trying to be thorough

Right-click on the "pong" target and choose get info.

[smartalco]

Right-click on the "pong" target and choose get info.

same thing again on the pong folder under targets and it brought up a window very similar to the "Configure SCM" window,
already did

[akb825]

What's it set at under Configuration? (note that it would be best if you set it to "All Configurations" so the linker flag works under every configuration

[smartalco]

it is set to "all configurations"

[akb825]

Try cleaning and re-building, then. If that doesn't work, you may just want to post the project so we can take a look at it.

[smartalco]

^did that, made a completely new project with the same code, same thing, although adding -lncurses definitely made a difference, different error before and after anyway

here is the project (hosted on wikiupload) http://www.wikiupload.com/download_page.php?id=33515 (if you cant figure it out, its console pong, in an early version...)

[akb825]

Builds without problems here... (well, 2 warnings, but no errors)

[smartalco]

maybe its a couple of the additional libraries i have installed... i never use them so i think im just going to reinstall the developer tools, see if that helps (i havent updated xcode in 9 months either anyway...)

[smartalco]

did that^ still doesnt work :/, anyone have any other ideas?
