Topic: CPUMiner compilation problem (Read 1697 times)

Silly me, forgot to add C:\MinGW64\bin to the PATH. Now minerd.exe compiles correctly and even runs on my machine (but not on another machine getting 0x7B error) I'll continue to dig.

Greetings,

To start with, I'm planing to use cpuminer to mine scrypt jane based coins, I have a relatively new 12 core Windows server, is this a good idea ?

Anyway, since cpuminer is blocked by mcafee I decided to build it from source on my Windows 7 x64 workstation.
I followed the tutorial https://bitcointalksearch.org/topic/m.3081964 to the letter.

However, I'm having a problem in the make step.
...
./configure --host=x86_64-w64-mingw32 CFLAGS="-O3 -march=core2"
make

I'm getting the following error message:
$ make

If I remove the --host flag as seen below compilation works but the resulting executable is 32 bit:
./configure CFLAGS="-O3 -march=core2"
make

Any suggestions are appreciated.
