| 03:17.36 | brlcad | hcurtis: those look very good on both counts, and I see you got it c89 compliant which is also good |
| 03:18.29 | brlcad | hcurtis: next comes the next hard leap and you'll almost certainly need to ask questions, but first did you have any questions on static vs. dynamic memory allocation? |
| 03:19.01 | brlcad | do you feel like you understand how those two do the same thing, but the memory used in that integer array is managed slightly differently? |
| 03:22.22 | brlcad | hcurtis: if you don't have any questions, then the next big step is to convert your dynamic version to using our libbu library API instead of the standard library |
| 03:23.58 | brlcad | to do that, you'll include our bu.h header and call bu_malloc and bu_free instead of malloc and free |
| 03:24.46 | brlcad | libbu's API is identical except they take an extra string argument, so malloc(i*5) becomes bu_malloc(i*5, "alloc something times five") |

After I got the C programs working in my compiler, I tried to do research to understand what I needed to do to get them working using the libbu API. I wanted to impress you by figuring it out myself, but unfortunately, that didn't work out. Thank you for the info you just gave me about bu.h and such. It was exactly what I was trying to figure out. I'll continue working on it right now. |

| 06:55.41 | oana_ | hcurtis, where do you have the bu.h file? and do you know the difference between including headers between <> and including them between "" ? |
| 06:56.13 | oana_ | this might be a good start to understand headers and such http://gcc.gnu.org/onlinedocs/gcc-3.0.1/cpp_2.html |
| 07:00.09 | hcurtis | Hi, oana_. I include the bu.h header in this program that I am trying to compile: http://paste.lisp.org/+323F |
| 07:01.04 | hcurtis | By the way, thank you for the information. |
| 07:05.23 | oana_ | yes, hcurtis I've seen it, but the idea is that for #include <bu.h> the compiler will look for your header in a set of directories pre-designed by the compiler, but it won't find it there - cause I don't think you put it there. When you use #include "bu.h" the linker looks for the header file in your current folder/the folder where your .c/.cpp file is. |
| 07:05.59 | oana_ | Here's another explanation of the difference between the 2 http://stackoverflow.com/questions/21593/what-is-the-difference-between-include-filename-and-include-filename |
| 07:06.15 | hcurtis | Ok |
| 07:06.25 | hcurtis | Wow. I had no idea. |

Bu.h has a line that says #include “defines.h”, and defines.h has a line that says #include “common.h”. However, that’s where the compiling stopped. Apparently, common.h is supposed to be in the same directory as defines.h, but in the source files I have, it is not. (I did f |
| 08:25.25 | oana_ | hcurtis, so what you mean is that you don't have the defines.h file, right? |
| 08:28.39 | hcurtis | No, I do have the defines.h file. The problem is that the common.h file is not in the directory that the defines.h file says it should be in. |
| 08:33.59 | oana_ | hcurtis, what error do you get? |
| 08:34.49 | oana_ | actually bu.h has #include "./bu/defines.h" meaning that the defines.h file would be found in the default include folder under the "bu" folder that is found there |
| 08:35.27 | oana_ | and defines.h has #include "common.h" meaning that the common.h file would be found in the include folder directly |

| 08:52.26 | hcurtis | I suspect that the code was written under the assumption that the top-level directory is the include/ directory.

That is the top-level directory, and the include directory is inside that. |
| 09:04.23 | oana_ | hcurtis, actually I think that it has to do with CMake and the way the includes are structured in brlcad. I might be wrong,and you might want to ask a second opinion on that one. But the files from the include folder are build as public headers that are after included as such in projects, using CMake. You can look at brlcad-svn-trunk/include/CMakeLists.txt and then take as an example one of the modules build in brlcad, mged for example, and look at brlcad- |
