Litecoin: makefile.unix:186: recipe for target 'obj/checkpoints.o' failed make: *** [obj/checkpoints.o] Error 1

[crawler080]

I would appreciate any help I can get on this issue.

I've edited rcpcrawtransaction.cpp line 242 and removed "&" and "const" as shown in the tutorial. I then compiled the src folder "make -f makefile.unix" but I've been getting this error:

Thank you in advance!

Hey there,

Litecoin no longer uses the makefile.unix file, that was for versions 0.8.x or before. Please use the latest master or 0.16 branches. Build instructions can be found here: https://github.com/litecoin-project/litecoin/blob/master/doc/build-unix.md

Hey !

sudo apt-get remove libssl-dev
sudo apt install libssl1.0-dev

For me works in Ubuntu 18.4.

Enjoy

CCDO5.. I did the same thing as you but I am getting fatal error: openssl/bn.h: No such file or directory. Any tips? Were you able to create your own crypto? Im doing it on Ubuntu 20.04.1

jdavid18, so let's make it clear the apps did not get updated from years. i used most recent ubuntu with fosel name (if i remember) and most of apps are for older ubuntu versions so i kept getting errors so my recommendation is try to download bionic version :D
