# QRL utilities in C
Still in its draft
Based from github.com/theqrl/qrl
Requires:
-lcrypto -lleveldb -ljson-c -lsnappy -lpthread
Build dependencies: `libbost-dev`
# Building on Linux. Ubuntu
```
sudo apt install lib{leveldb,json-c,ssl}-dev
make -j4
```
# Building on Windows. Msys2 (ucrt64)
```
pacman -S mingw-w64-ucrt-x86_64-{leveldb,json-c,boost,openssl,gcc,make}
make -j4
```
Note that ASan isn't supported on non LLVM/Clang based environent on msys2,
so remove those `-fsanitize=address` if it is been set.
## Test
This would retrieve valid blocks from the mainnet and feed it to qrlc for testing.
```
make -C src test
```
# Cross compiling
# Known building issues
Compiling with gcc produces linker from undefined symbols in librandomx.a.
This seems to be a problem when linking a C++ library [which uses the C++
standard libs] using a C compiler. And that C compiler couldn't properly
call ld with appropriate flags needed by a C++ library. Either (1) use a C++
compiler, or (2) pass appropriate linker flags with `-Wl,someflags` or some
library when using a C compiler or (3) use the C compiler to only compile
into .o objects and use a C++ compiler to link those objects.
