Re: [PDCurses] PDCurses compilations problems
P.S. You'll also want to specify the include directory, so that it picks up PDCurses' curses.h rather than the system's: gcc -I/usr/local/include/xcurses -oappname appname.c -lXCurses Either that, or modify the source of appname.c to specify xcurses.h instead of curses.h; but I don't recommend that. -- William McBrine <[EMAIL PROTECTED]>

In Linux, it will prefix the name with "lib", and suffix it with ".so" or ".a"; in other words, it will look for the files "libpdcurses.so" and "libpdcurses.a". In Mac OS X, the suffix for shared libraries is ".dylib" instead of ".so". So, have you got one of those files in your library path? Probably not. For one thing, the X11 version of PDCurses (which is what you have in Linux or Mac OS X), for historic reasons, is built with the name "XCurses" by default. The corresponding option would thus be "-lXCurses" rather than "-lpdcurses". You could change it to "pdcurses"; but if you had, you'd know it. Secondly, you don't have it in your library path unless you've installed it there. That would mean you either ran "make install" (or perhaps "sudo make install"), with no errors, or else manually copied it to an appropriate place. Now, "make install" doesn't work correctly in Mac OS X, because make sees the file "INSTALL" and thinks it satisfies the rule. This only happens in Mac OS X (and not Linux or other *nix), because of its case-preserving but non-case-sensistive file system. (Fixed in PDCurses CVS. You can fix it by adding a second colon after "install:" in the Makefile.) You can also specify the full pathname to the library file directly. In that case, you don't use "-l". Example -- if it's installed: gcc -ofirework firework.c -lXCurses If it's not installed: gcc -ofirework firework.c ../pdcurses/libXCurses.a > I'm completely stuck, should I put a file in /usr/bin/ld ? /usr/bin/ld is the name of the linker executable, not a directory. -- William McBrine <[EMAIL PROTECTED]>
Re: [PDCurses] PDCurses compilations problems
Hey Gareth, To help ld find the library, assuming it's not somewhere like /usr/lib, you need to either add a -L so it can find the library. I believe you can also do -l /path/to/pdcurses/lib/libpdcurses.a and it will work correctly as well. I hope that helps.

[PDCurses] PDCurses compilations problems
Hello, I've been racking my head for hours trying to compile PDCurses programs on my Mac OS X installation, and Linux. I'm in a dire need of help. What I'm trying todo is compile the demos included separately using the following; $ gcc firework.c -lpdcurses -o firework and get the following error; /usr/bin/ld: can't locate file for: -lpdcurses collect2: ld returned 1 exit status I'm completely stuck, should I put a file in /usr/bin/ld ? I've got gcc installed and all the apple development tools. Do I have the compile syntax correct ? I've looked in the make file in the demos folder, but couldn't figure which flags to use. Thanks for your time Gareth
