That should be in /usr/include/sched.h which is in a virtually standard package for compiling anything: libc6-dev

Yes, sure, it's still there. But the problem isn't with the header file. This commit breaks the build:

I'm not sure how it works on your system though.

Gnu source is in config.h now
So it should be pulled in by everything
Make sure you have done ./autogen.sh and then ./configure

I've decided to rename this application cgminer which means "cpu and gpu miner" or "ck and garzik miner" or "c gpu miner" or... just plain cgminer.

So I've moved the git tree to
https://github.com/ckolivas/cgminer

and have started renaming files and have cleaned up the git log, rebasing it, for it to build with the name cgminer version 1.0.9

So I'm trying to clean all this code up for a meaningful release now.

Forgive my ignorance, but as this miner supports both GPU and CPU, does it "intelligently" pick which processor to use or do you have to tell it to either use the GPU or the CPU (or both)?

If it does not detect any gpus it will cpu mine. If it detects any gpus it will only gpu mine unless you explicitly tell it to cpu mine as well. I'm working on modifying the code to build in the absence of opencl code and be a pure cpu miner still if need be.

I pulled from the new tree, and everything appears to be working now. Thanks.

Feature suggestion: Option to set a different worksize for each GPU.

Updated tree:

I believe we've tracked down the cause of the libcurl bug as being signal handling in the dns lookup code. So I've disabled signal handling and this has allowed me to add multiple curl handles thus making each get work and submit work completely asynchronous rather than each getwork waiting on the previous one and so on. It is theoretically possible it could spend forever waiting for a dns resolve but I doubt this can happen in reality as the lookup code would have to timeout at some stage. I've also addressed a bug where it was possible after a longpoll that a gpu could be left idle without any work. New windows builds coming soon.

Is it possible to make it compile without AMD APP SDK? To run it as a pure CPU miner on a machine without any GPU.

Fixed parameter parsing. Now short parameters should work, and it wont crash with invalid parameters.

Updated tree:

It should build now without opencl as a cpuminer only. The help message should say what it is compiled for after it's built.

Did you do ./autogen.sh followed by configure first? If so, what was the output please?

The thing is that #include <CL/cl.h> line isn't wrapped in the #ifdef HAVE_OPENCL block, so the file is always included regardless of the OpenCL presence. There are more OpenCL-related bits in miner.h and mine.c which are always compiled.

Did you do ./autogen.sh followed by configure first? If so, what was the output please?
autogen doesn't output anything.
I had to remove the libcurl macro from configure and added the curl flags manually to the generated Makefile since RHEL5 doesn't have libcurl pkgconfig bits.
