Ubuntu: CPUMiner won't compile



Question:

I am trying to compile a CPUMiner program, but get errors which I don't know what to do about. I am compiling as said here:

http://www.return1.at/bitcoin-miner-ubuntu/

The error is:

checking build system type... x86_64-unknown-linux-gnu  checking host system type... x86_64-unknown-linux-gnu  checking target system type... x86_64-unknown-linux-gnu  checking for a BSD-compatible install... /usr/bin/install -c  checking whether build environment is sane... yes  checking for a thread-safe mkdir -p... /bin/mkdir -p  checking for gawk... no  checking for mawk... mawk  checking whether make sets $(MAKE)... yes  checking whether to enable maintainer-specific portions of Makefiles... no  checking for style of include used by make... GNU  checking for gcc... gcc  checking whether the C compiler works... no  configure: error: in `/home/tomino/_software/cpuminer':  configure: error: C compiler cannot create executables  See `config.log' for more details  

And error in config.log:

gcc version 4.7.3 (Ubuntu/Linaro 4.7.3-1ubuntu1)   configure:3320: $? = 0  configure:3309: gcc -V >&5  gcc: error: unrecognized command line option '-V'  gcc: fatal error: no input files  compilation terminated.  configure:3320: $? = 4  configure:3309: gcc -qversion >&5  gcc: error: unrecognized command line option '-qversion'  gcc: fatal error: no input files  compilation terminated.  configure:3320: $? = 4  configure:3340: checking whether the C compiler works  configure:3362: gcc -03   conftest.c  >&5  gcc: error: unrecognized command line option '-03'  

Please help someone. Thank you


Solution:1

Ok I have found the problem. It is rather stupid...

In tutorial they say to run:

./configure CFLAGS="-O3"  

But the flag IS NOT 03 (zero three) but O3 (o three) Thats all...
