Can you fix the issue with compiling on Windows machines in next releases?

It compiles fine on windows. There is an extensive readme on how to do it included in the source. Don't guess, follow the instructions.

None of those matter for scrypt mining. No CPU mining in cgminer is optimal, and that's intentional as it is only there for legacy reasons and testing and I don't wish anyone to mine on CPU with cgminer for anything other than an academic experience.

Try to play with this key

Code:

--algo|-a Specify sha256 implementation for CPU mining:
auto Benchmark at startup and pick fastest algorithm
c Linux kernel sha256, implemented in C
4way tcatm's 4-way SSE2 implementation
via VIA padlock implementation
cryptopp Crypto++ C/C++ implementation
sse2_64 SSE2 64 bit implementation for x86_64 machines
sse4_64 SSE4.1 64 bit implementation for x86_64 machines (default: sse2_64)

auto is not always the best choice

Thanks, it works on one machine (win7 32)

on Win7 64 still no workie. I`ll try reinstall mingw and stuff.

Compiled, running, but LTC CPU mining performance is less than I expected.
CPU miner minerd (https://bitcointalksearch.org/topic/an-even-more-optimized-version-of-cpuminer-poolers-cpuminer-cpu-only-55038) is making about 3kh/core where cgminer only about 1kh/core.
Tried different -O2 -O3 -Wall, even added yasm to my mingw installation - same results.
When yasm is present I can not use -msse2 option because it fails on make.
As far I know cgminer include pooler cpu miner code, why so much difference?

I open thread to not mess much in main cgminer thread and allow to easy find windows compiling related troubles.
I`m trying to compile it on win7, do everything like it is in windows-build.txt file but hit wall.

I want cpu+gpu+scrypt and nothing more:
$ CFLAGS="-O2 -msse2" ./configure --enable-cpumining --enable-scrypt --without-libudev

It is not detecting Opencl...

Code:

------------------------------------------------------------------------
cgminer 2.8.3

Tried git zip, and source tarballs...

Code:

It is installed, ADL files copied etc...
