[BOUNTY] Error when compiling QT-wallet

[bitsta]

Hi,

i keep getting 2 errors when i try to make an executable QT application.

so after running qmake bitcoin-qt.pro and make -f Makefile i get this output:

Code:

[b]src/sync.h:62:17: error: expected expression
    void lock() EXCLUSIVE_LOCK_FUNCTION()[/b]

is it a known issue? hope you can help.
I ll pay 0.02 BTC as BOUNTY for the information which leads to successfull compilation.

thank you and all the best,

that issue above is solved but i still get an error:

Code:

ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status

Bounty doubled to 0.04BTC for the information which leads to successfull qt-build.


thanks in advance

yes i can also compile any scrypt based coin without any issues.

i use OSX 10.7.5 and try the qt make for zetacoin (latest source).

Open your .pro file in the QT editor, and add this line:

Code:

CONFIG -= x86_64

Bounty is appreciated to: 1MFwoNsmEFesZfQgNWJjbVJseNT4GZMSq6

i tried that but still got the same error.

Could you post the exact symbols, that are not being found? There must be some longer, more cryptic message.

You're missing an object file when you run "gcc -o ..."

Aaaaaaah youre compiling on mac! now the issue is clear.

There are two implementations of the standard C++ library available on OS X: libstdc++ and libc++. They are not binary compatible and libMLi3 requires libstdc++.
On 10.8 and earlier libstdc++ is chosen by default, on 10.9 libc++ is chosen by default. To ensure compatibility with whatever fails, we need to choose libstdc++ manually.
To do this, add -stdlib=lib(std)c++ to the linking command.

Could you try adding those two lines to your .pro File?

Code:

QMAKE_CXXFLAGS += -std=c++11
QMAKE_CXXFLAGS += -stdlib=libc++

if this doesnt work try

Code:

QMAKE_CXXFLAGS += -std=c++11
QMAKE_CXXFLAGS += -stdlib=libstdc++

Always clean and rerun qmake before compiling.

doesn't work...
