I have compiled Linux and GUI QT wallet without any error but when I tried to compile Window wallet on Window using MINGW and on Ubuntu using Cross compilation each effort ends with an error as below
/src/leveldb/libmemenv.a: error adding symbols: Archive has no index; run ranlib to add one
collect2: error: ld returned 1 exit status
Makefile.Release:453: recipe for target 'release/coin-qt.exe' failed
any help will be much appreciated, there are multiple threads which are concerned with this error but none of them give solution
