[n00b] cgminer crashing, win7

[blasthash]

Hello all,

Title summarizes the issue - I'm trying to run cgminer on a Windows 7 desktop, and even after installing the APP SDK cgminer will not startup, nor will GUIMiner - GUIMiner initially appears to start, however its icon appears in the taskbar and upon mousing over it, disappears and the program quits. I'll list my thoughts on what it could be below, we'll play some confirm-or-deny:

1: Could it be a run-as-administrator issue? The desktop is my father's, and I'm only using it in interim for Windows use for FPGA and uC development IDEs, but figured if I could rig it to contribute to my LTC efforts, more power is never a bad thing in this branch of the world.
2. cgminer-nogpu.exe executes and runs perfectly - thus suggesting issues with the OpenCL drivers or GPU mining. Are there drivers required for GPU mining other than the APP SDK that are required for cgminer functionality?
3. Both the 32-bit binary and normal copies of GUIMiner-scrypt (~/guiminer and ~/guiminer-scrypt_win32_binaries_v0.04 copies) fail in the same manner, with both copies of cgminer in each failing to execute.


Here are the specifics of the desktop, as to what I've installed and other such stuff:

- Windows 7 HP SP1
- i7 920 (2.67GHz), 8GB RAM
- Radeon 4300/4500 GPU, driver version 8.850.0.0
- AMD APP SDK v.2.8
- GUIMiner-scrypt v0.4

Any solutions or help with a workaround? This is causing me to beat my head almost quite literally against a wall - I'm running three machines, one Win7, one Mac OS X 10.8, and one Ubuntu 12.04, and I haven't been able to get cgminer to successfully compile on any - meaning for the time being, I'm stuck using a horribly-slow Java Web LTC CPU-only miner tool.

For Windows I believe you have to track down aticalcl.dll, aticaldd.dll, and aticalrt.dll  in Windows\system32, then copy them to your work folder and replace the ati with amd in the file name.  I thought guiminer came with the files already.

If you provide some output from cgminer, I (or someone better) might be able to help.

When you say work folder - do you mean the highest-level directory (i.e. /guiminer) or one of the /lib folders?

I would give any output from cgminer, however it crashes immediately - via the opaque "Application not responding" screen mask. cgminer-nogpu appears to start working after prompting for URL, worker U/N and pass.

However, I'm pretty sure it's not doing anything, as even with deliberately taxing settings I came back 10 minutes later with the fan not anywhere above no-load idle. This stock 1366 sink is a menace and can wake a neighborhood, and I couldn't even hear a whisper from it.

But, provided, name them as:

Code:

amdcalcl.dll
amdcaldd.dll
amdcalrt.dll

?

Thanks for your help, BTW. It's much appreciated.

Worked on what you told me...tracked down the ati libs. They had 64 (for 64-bit presumably) appended at the end, so (aticalcl64.dll, aticaldd64.dll, aticalrt64.dll) I renamed them and removed the 64 from the name.

I grabbed them from ~/Windows/System32 rather than a subdirectory.

Upon moving them to the ~/cgminer head folder, same result. Immediate opaque mask and crash upon startup.

Also, reaper (in ~/guiminer/reaper) also quits immediately during startup, albeit not by the same failure mode. I then tried placing the DLLs under ~/guiminer/library, wondering if all executables are referenced there, still no go. GUIminer still will not boot, nor will any of its backends.

Needless to say, I'm starting to get a bit pissed off with this computer.

What are your settings while running reaper or cgminer? When you first load the programs - ie. First Usage of the program, there is a binary file that needs to compile.  If there are too many errors while in this compile phase, the program will quit without reason.  I suggest using a low thread concurrency (3520 or so) and a low aggression setting (10 or 12 for bitcoin) to test the programs compatibility with your system.  Even in the auto phase, my copies seemed to quit while in this compile phase while loading them without correct settings.
