CMake integration

[dkaparis]

Greetings,

I have set up a mirror hg repository over at bitbucket for integrating the CMake build system:
http://bitbucket.org/dkaparis/bitcoin-cmake/

It's based on latest SVN and I'm regularly updating. My modifications are addition of build files and the fix for MSVC non-debug runtime compiling of the secure_allocator class I posted some time ago.

See the included build_cmake.txt file for more details.

Currently it's tested and works for Visual C++ 2008, both IDE and command-line builds.
Still not tested: MSVC x64, MinGW and UNIX builds.

Use it as you deem fit. Contributions are welcomed.

It now builds on FreeBSD. Tested on 8.1 x64. I have no graphical environment on my test machine, so I haven't tested with wxWidgets. Volunteers are welcome.

Provided you set up all dependencies from the ports tree and have CMake installed, building Bitcoind should take only this:

hg clone https://dkaparis@bitbucket.org/dkaparis/bitcoin-cmake
cd bitcoin-cmake
mkdir build
cd build
cmake ..
make


Haven't tested on Linux yet, but it should be virtually the same. Again, volunteers are welcome.

Cheers.

thanks for this cmake thingy

I managed to compile in on linux (uname -a = Linux unimatrix0 2.6.34-gentoo-r6 #1 SMP PREEMPT Wed Aug 25 11:27:50 CEST 2010 x86_64 Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz GenuineIntel GNU/Linux, if anyone wants to know)
I just needed to remove some wx libs from the linker command because it was complaining it cannot find them. As it seems to link fine without them, i guess they are not really needed, and you can remove them. I have a patch below:

Thanks, I'll add the change. I remember just copying the lib names straight from the original makefile, I suspected not all are used.
It's also worth noticing it can build bitcoind (the headless version) without any wxWidgets libraries at all (in fact I did that on my FreeBSD system).

I just cloned it and ran cmake and got this:

-- Found wxWidgets: TRUE
-- Found OpenSSL: /usr/lib/libssl.so;/usr/lib/libcrypto.so
-- Boost version: 1.46.1
-- Found the following Boost libraries:
--   system
--   filesystem
--   program_options
--   thread
--   date_time
--   regex
-- Could NOT find DB (missing:  DB_LIBRARIES)
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
DB_LIB
    linked by target "bitcoin" in directory /home/phma/crypt/bitcoin-cmake
    linked by target "bitcoind" in directory /home/phma/crypt/bitcoin-cmake

-- Configuring incomplete, errors occurred!

I have several versions of db installed:

db-2.7.7nb3 =        Sleepycat Software's Berkeley DB version 2
db3-3.11.2nb4        Sleepycat Software's Berkeley DB version 3
db4-4.8.30 =         Berkeley DB version 4 from Oracle
db46-4.6.21 =        Berkeley DB version 4 from Oracle
db5-5.2.28 =         Berkeley DB version 5 from Oracle

And why is it looking for wxWidgets instead of Qt?

[Pieter Wuille]

The previous post in this thread is 1.5 years old. We've since switched from the wx GUI ("bitcoin") to a Qt GUI ("bitcoin-qt"), and the version requirements for several libraries changed as well. We've also switched from SVN to GIT...

In any case, that cmake file will be severely outdated by now.

[phma]

Is anyone up to updating the CMake file? I'd love to get Bitcoin to build on my box, but the existing build system (or lack thereof) just doesn't work on it. I have no problem building Vidalia (a Qt app which uses CMake as build system), and I've been porting my projects to CMake, but none of them are GUI projects. I started to port Bitcoin to CMake, found that CMake doesn't have a library find module for Berkeley DB, searched for it, and landed on dkaparis's site.

[Pieter Wuille]

What problems do you have with the current build system, and on which platform?
