You can recursively copy the library dependencies (which can be determined using otool -L), and change their expected path in the libraries themselves, and in the executables as well (using install_name_tool). And of course, your application should be designed to look (for e.g. images, documentation, etc.) for paths relative to the executable path (instead of absolute ones).

Linking fortran libraries into a unix-level executable.

Someone recently popped into my office with a question that this list might be able to help me with. They have a program written in fortran. I can install a version of gcc which includes gfortran, and compile their program. It works great. Now what they'd want to do is to come up with an executable that people in their class could run, *WITHOUT* needing to install Apple's developer tools and the package for gfortran. Sort of like static-linking it for everything in the gfortran/gcc package, but not in Apple's own system libraries. Is there some way to do this? I tried various tricks based on reading the man pages, but haven't had any success. -- Garance Alistair Drosehn = drosih(a)rpi.edu Senior Systems Programmer or gad(a)FreeBSD.org Rensselaer Polytechnic Institute; Troy, NY; USA _______________________________________________ Do not post admin requests to the list.

No, it's not. The problem is that you're not in userspace, which is where these library routines are located; you're in kernelspace, and you have a very limited number of routines available to you. > I need to write data to a file for debugging purpose and am not able to > use standard library <fstream> or stdio.h routines.

The best thing for you to do is to use the IOLog() function within IOKit and rely on the syslog interface to do the actual logging to a file. While it's conceivably possible to write directly to a file in kernelspace, it's a really bad idea. If you're needing to load a configuration file, run a userspace program at load time to do the parsing and pass the values in via a named device, typically with the ioctl(2) kernel call. If you want more information, I'd strongly recommend getting yourself a textbook on kernel internals, such as "Design and Implementation of the 4.4 BSD Operating System" by McKusick et al. While it doesn't directly address Darwin internals, it's an excellent guide to understanding kernel programming in general, and in particular, why there are certain things you never want to do directly from kernelspace. -- Tilghman _______________________________________________ Do not post admin requests to the list.

I am using the SoundFlower source code for learning Audio HAL. #include <iostream> also gives error even by explicitly specifying the header path for 10.4u sdk. Can somebody please throw light on this issue. I am completely noob in driver stuff. I need to write data to a file for debugging purpose and am not able to use standard library <fstream> or stdio.h routines. If these are not allowed please suggext me the method how can i write to files while working with libkern.
