used 

./configure DFLAGS="-03"

and this is the config.log

my system is ubuntu 14.04 and the system details say the os is 32 bit. any help would be great as the compiler fails on anytime I try to use it, not just with this install.

  • Are you sure you own the cpuminer-2.4.2 directory? Commented Jul 12, 2015 at 16:53
  • Try the command in quotes to isolate permission issues--- "echo "void main(){printf(\"hello world\n\");}" |gcc -x c - -o /tmp/hello;/tmp/hello" ... once you execute it you should see "hello world" printed on console Commented Jul 12, 2015 at 17:18
  • I used git to get the files and the directory was created, I did not use superuser with git, just git, the directory was created inside my home directory so I think that I do own the directory. Commented Jul 12, 2015 at 17:19
  • yes after I execute echo "void main(){printf(\"hello world\n\");}" |gcc -x c - -o /tmp/hello;/tmp/hello I get hello world Commented Jul 12, 2015 at 17:22
  • checked permissions on the directory and it is mine..... Commented Jul 12, 2015 at 17:25

My guess would be that you have the basic C compiler installed, but not the headers for the standard library. Try:

sudo apt install libc6-dev

[Edit: this produces similar symptoms, but wasn't the case here. The CFLAGS answers appear to be correct.]

  • libc6-dev is already the newest version. Commented Jul 12, 2015 at 17:24
  • In that case, look at the config.log file, which should have information on what went wrong. Commented Jul 12, 2015 at 17:25
  • the output of the config.log is at the top in the original post Commented Jul 12, 2015 at 17:26
  • my bad, thought I had pasted config.log in originally, is added now....... Commented Jul 12, 2015 at 17:55

From the config.log:

configure:3478: gcc -03 conftest.c >&5 gcc: error: unrecognized command line option '-03'

The option is -O3 with the letter O, not the number 0 (zero). So, you should run, as given in the README:

./configure CFLAGS="-O3"

Looks like your CFLAGS has a zero instead of capital O. That is invalid, and causing the compilation to fail. You can fix it, but really, look for a later version of the package which has been fixed.

  • tried the newer version first and it failed so i removed that and tried this version and it failed so i figured there was some other problem. thanks for the fix Commented Jul 12, 2015 at 20:18

I was having this exact same problem trying to install tivodecode on a base build of Linux Mint 17.3. I tried the:

./configure DFLAGS="-O3"

command but with no effect. So I tried:

sudo apt install libc6-dev

to install the latest C headers. I tried the ./configure command again with no variables and all went well. The make and make install commands also completed successfully. My recommendation is to make sure the latest C headers are installed and then run your ./configure command.

  • Also using Linux Mint and this fixed it for me. Commented Sep 27, 2022 at 1:55

You can try to install build-essential

sudo apt-get install build-essential
