Cannot find -lcrypto
I am compiling holiman's latest release (8th January 2015) and it fails with
mingw32/bin/ld.exe: cannot find -lcrypto
My tool chain builds up to 854 successfully. The code was downloaded as proxmark3-master this morning.
Any help would be appreciated.

Re: Cannot find -lcrypto
You need to have OpenSSl installed or use the folder (filled with the needed files ) that Asper made. There was a discussion about it somewhere.. maybe on the ask/demod thread from Marshmellow..

Re: Cannot find -lcrypto
Thanks Guys, got that downloaded, but the problem has remained. I had installed mingw directly on C, could that be an issue?
Fuller error message is:-
c:/mingw/bin/../lib/gcc/mingw32/4/7.2/../../../../mingw32/bin/ld.exe: cannot find -lcrypto
collect.exe: error: ld returned 1 exit status
make[1]: *** [proxmark3] Error 1
make[1]: Leaving directory '/c/proxmark3-07c/client'
make: *** [client/all] Error 2
Many Thanks

Re: Cannot find -lcrypto
I got that error until I added libeay32.dll http://proxmark.org/forum/viewtopic.php … 544#p13544
I put it in client/DLLs and then added it to the client make file libs.

Re: Cannot find -lcrypto
if you are using qt 4.x then you may also need to remove the top -LM -lcrypto from the makefile (leaving the lower one next to 99)

Re: Cannot find -lcrypto
eventually we will need openssl folder and libeay32.dll.

Re: Cannot find -lcrypto
Many thanks marshmallow, that built, which version of QT are you using at present, I assume if I change to that this will mean this will keep me in sync?

Re: Cannot find -lcrypto
I am still using 4.x, but many are using 5.x. Soon, I hope we all get on the same page.
