Hello,

I could do with a little help understanding the final stage for me in a great learning experiment regarding bitcoin and altcoins I have been doing in my spare time.  

Before bitcoin I had never used Linux, was a windows user through and through but have switched over and taught myself a lot and enjoyed the whole learning experience.  So please be gentle with me for failing to be able to complete this task on my own.

Trying to build a binary for myself on linux (ubuntu) that will work on other linux installs without having to install the dependencies

I have installed the dependencies on ubuntu. Now when I build I need to pass the Static flag in correct? but I seem to not understand how to declare this correctly Sad

I am all for learning so please feel free to expand on things that are important areas to understand for me... or tell me where I am being a fool and making a meal out of something.  

Here is the sample makefile I have

# Hardening

Now it all works when building a dynamic library ... however changing in the makefile
LMODE=static
LMODE2=static
it errors.. I am investigating this error cannot find -lgcc_s

Rather than changing in the makefile as well the values for LMODE, can I not pass this in on my make -f makefile.unix command?

Many thanks for your help and for reading, if you want more info or code etc just ask sorry I am not as experienced as many others and I am completely self taught so there may be some alarming gaps in my knowledge.
