Hi all,

I just need an help to understand this error during compiling.

I'm trying to compile the ocminer following this instructions on a Raspberry PI 2 :

sudo apt-get update -y
sudo apt-get -y install git automake gcc g++ libcurl4-openssl-dev libssl-dev make

git clone https://github.com/ocminer/cpuminer-hmq1725
cd cpuminer-hmq1725/
./autogen.sh
./configure --with-crypto --with-curl
make

After the make command, it starts to compile but gives me some error (italian language):

gcc -std=gnu99 -DHAVE_CONFIG_H -I. -fno-strict-aliasing -I./compat/jansson -I. -Wno-pointer-sign -Wno-pointer-to-int-cast -g -O2 -Iyes/include -Iyes/include -MT algo/cpuminer-cryptonight.o -MD -MP -MF algo/.deps/cpuminer-cryptonight.Tpo -c -o algo/cpuminer-cryptonight.o `test -f 'algo/cryptonight.c' || echo './'`algo/cryptonight.c

Someone of you could give me some suggestion?
Thank you in advance

I'm not familiar with the ocminer version but this looks like a coding error.

If you're comfortable ediiting the source code you could try editting algo/cryptonight.c line 84 and remove the word static.

If that doesn't work there may be multiple definitions and it gets too complicated for non-coders.

Edit: just noticed you are using an RPI. That i sprobably your problem. No one would bother builduing a CPU
miner for an RPI, it's not worth it.
