To-do list?

[Michael]

What use might you have for a C/x86 assembly programmer accustomed to low-level work?

[Luboš Doležel]

Too much stuff :-)

You could work on:

* AGL and related basic Carbon APIs

* IOKit support (working with libudev, libusb...)

* Work on Core Audio design/implementation (nothing done yet)

* Implement Apple Events C APIs (nothing done yet)

* Make Apple's open source Security framework compile with CMake (comprises Keychain and many other APIs)

* help iron out our issues: https://github.com/LubosD/darling/issues

A good idea is to find a nice (prefferably simple) application that you'd find nice to make working under Darling and start hacking.

Luboš

anyone know if we could get this to work with cygwin?

You don't have permissions, nothing more complex than that. 

If it doesn't pose a security risk, run the script as root. 

A better way to troubleshoot would be to ensure that you, and gcc, have rwx permissions on the working directory

As I promised I am trying again to compile the code, following the instructions on http://darling.dolezel.info/en/Build/Ubuntu#GNUstep_.26_friends for ubuntu 13.04 (mine is a 64 bits) I have the first stop on GNU Step Make, when I run 

$ sh configure

checking for gcc... gcc

checking for C compiler default output file name... a.out

checking whether the C compiler works... configure: error: in `/media/flipefr/Data/SME/Google Drive/software/Darling/gnustep-make':

If you meant to cross compile, use `--host'.

See `config.log' for more details.

In config.log I find:

If you meant to cross compile, use `--host'.

See `config.log' for more details.

Obiously the file a.out doesn't exist and if I try:

$gcc -V

gcc: error: unrecognized command line option '-V'

gcc: fatal error: no input files

compilation terminated.

until I finish all this steps I can't go forward because cmake will complain about variables 

You have called ADD_LIBRARY for library AppKit without any source files. This typically indicates a problem with your CMakeLists.txt file

You have called ADD_LIBRARY for library Carbon without any source files. This typically indicates a problem with your CMakeLists.txt file

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.

Please set them or make sure they are set and tested correctly in the CMake files:

LIBGNUSTEPBASE_INCLUDE_DIR

LIBGNUSTEPCOREBASE_INCLUDE_DIR

LIBOBJC2_INCLUDE_DIR

LIBOPAL_INCLUDE_DIR

It look like is only a problem checking the version of gcc, gcc -V doesn't work , but 

$gcc -v

COLLECT_GCC=gcc

COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-linux-gnu/4.7/lto-wrapper

Target: x86_64-linux-gnu

[...other variables....]

Thread: posix

gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-1ubuntu1)

Maybe is somewhere in the code where I can change -V for -v or crete some kind or alias.

In any case, thanks for the help

It's been a while since last time I checked this project, did you do any progress with CMake, I had lots and lots of problems trying to compile the code from the wiki in ubuntu and would like to know if there was any update just to try to check how it works now.

Many thanks

and keeping in mind and in root mode I try:

$echo $CC

clang

$echo $CXX

clang++

$sudo sh configure

checking for gcc... gcc

checking for C compiler default output file name... a.out

checking whether the C compiler works... configure: error: in `/media/flipefr/Data/SME/Google Drive/software/Darling/gnustep-make':

configure: error: cannot run C compiled programs.

If you meant to cross compile, use `--host'.

See `config.log' for more details.

The log is same as I pasted before (programs clang and clang++ works properly)

Thanks

Looks like nothing, I am leaving this thread, thank you

There must be something very seriously wrong with your system!

What filesystem are you trying this on?

I solved it, ( architecture wasn't aliased ) the problem was I was trying to build it on a ntfs filesystem in aext4 enviroment. I moved the code to the right partition. Thanks.

Hej - a lot of code is on GNU page. Especialy system call - i describe the - how to can be make work app with graphic user interface or cli and way of develope this calls. Look on IRC channel.

Second don't go to low-level work - this code exist- the functionally of it on GNU and other opne source base of code like on M.I.T or bsd is on hight level code. The main work it's rename a name of for example class, system calls, to creat object that coverage calls and system calls name. We must remember that shared library have table of symbol - app require system call ( system kernel level) or library calls to symbols with in.

Python has ability to load by ctypes table of sysmbols from shared library lik in windows *.dll or on Linux *.so f

iles.
