Building an altcoin

[r3wt]

and i have encountered 9768503 errors so far. most of them were easy fixes, some of them required the advice of a programmer, and now i am finally stuck on one i can't seem to fix. it has to do with the boost library as far as i can tell. maybe something didn't work during the install process?

mingw32-make: *** [NanoToken-d.exe] Error 1

i've bolded the error. can't for the life of me figure out what i did wrong. i installed boost, openssl, berkley db, and all that and now i'm stuck once again. bummer. any insights or suggestions? i humbly beg?

Delete all your makefiles, your boost directory in your pro file is more than likely wrong.

Should look like

windows:LIBS += -lshlwapi
LIBS += $$join(BOOST_LIB_PATH,,-L,) $$join(BDB_LIB_PATH,,-L,) $$join(OPENSSL_LIB_PATH,,-L,) $$join(QRENCODE_LIB_PATH,,-L,)
LIBS += -lssl -lcrypto -ldb_cxx$$BDB_LIB_SUFFIX
windows:LIBS += -lws2_32 -lole32 -loleaut32 -luuid -lgdi32
LIBS += -lboost_system-mgw46-mt-sd-1_53 -lboost_filesystem-mgw46-mt-sd-1_53 -lboost_program_options-mgw46-mt-sd-1_53 -lboost_thread-mgw46-mt-sd-1_53
BOOST_LIB_SUFFIX=-mgw46-mt-sd-1_53
BOOST_INCLUDE_PATH=C:/deps/boost
BOOST_LIB_PATH=C:/deps/boost/stage/lib
BDB_INCLUDE_PATH=c:/deps/db/build_unix
BDB_LIB_PATH=c:/deps/db/build_unix

OPENSSL_LIB_PATH=c:/deps/ssl

Did you install the deps yourself??

[muddafudda]

If your directories are different change them including if you have different version numbers of each dep.

yeah, i installed them based on this guide for building bitcoind  https://bitcointalk.org/index.php?topic=149479.0

this is what it looks like in my makefile.mingw

it took some trial and error before i got it like this and it works but then i get the above mentioned error

i'm building this based on the megacoin source. from what i can gather it was compiled with boost 1.52 so i'm gonna try to install boost 1.52 and then change the makefile and attempt to compile again.

You know what would really be a cool altcoin:    a coin built WITHOUT the boost library

if i was smart enough, i probably would.
