Compile from source error on Debian testing (wheezy)

[yanom]

So I got the latest Spring source tarball, ran

Code: Select all

cmake . 

and it came out with no errors. But then I ran make, and it produced this error:

Code: Select all

Does anyone know how to fix this? Also, Debian uses GCC version 4.6.1
I'd heard that GCC4.6 can cause problems, is GCC4.6 to blame here?

we told you, that you desync cause debian testing compiles their spring with GCC 4.6, and that you should either get a package from debian stable or ubuntu (which seems not to work for you), or compile spring with GCC 4.5-.
GCC 4.6 does not match GCC 4.5-
you have to use GCC 4.5-

My official Debian package contains a patch for gcc-4.6 compatibility, see http://anonscm.debian.org/gitweb/?p=pkg ... 5097.patch

Unfortunately g++ 4.6 builds of spring 0.82.7.1 have sync problems.

Unfortunately g++ 4.6 builds of spring 0.82.7.1 have sync problems.

Exactly! Is there a way to build with g++ 4.5?

CMake uses variables for this, have a look at http://cmake.org/Wiki/CMake_Useful_Vari ... _and_Tools

[yanom]

ok, how do I set CMAKE_C_COMPILER and CMAKE_CXX_COMPILER variables?

And, will this change fix my problem?

[abma]

cmake . -DCMAKE_C_COMPILER=/usr/bin/gcc-4.6 -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.6


but better use the ubuntu-ppa:
deb http://ppa.launchpad.net/spring/ppa/ubuntu natty main
deb-src http://ppa.launchpad.net/spring/ppa/ubuntu natty main

they will sync!
i don't know which version works, but one of the ubuntu-packages should work, look here which versions are avaiable: https://launchpad.net/~spring/+archive/ppa/+packages or
http://ppa.launchpad.net/spring/ppa/ubu ... /s/spring/

the sync-errors doesn't come from the compiler only... or... we don't really know. i guess they are from the boost-libs but... just a guess.

[yanom]

ok, I'm trying to get the PPA's to work.

These errors go away in next spring release right?

[yanom]

ok, the PPA's won't work because debian repos already have the latest spring version (but it's the broken one with the sync errors) and when I try to "force version" to the ubuntu PPA version in synaptic it just stays on the debian version.

[abma]

deinstall (afaik "apt-get remove spring") the debian spring package + install then the packages from the ppa.
