boost compilation error

[skaluzka]

hi,

I'm facing below compilation errors after your last commit...

...

but pyconfig.h is available in my system:

[kaluzka@CNU3099HPJ include]$ find . -name pyconfig.h -type f
./python2.7/pyconfig.h
./python3.4m/pyconfig.h
[kaluzka@CNU3099HPJ include]$ 

I'm using arch linux where default python is python3 (maybe that's the issue). do you know how to fix it?

Hi,

I suppose we have to pass the python path to build boost. In the mean time, you can use the system boost, as it was done before, by setting the cmake option VERA_USE_SYSTEM_BOOST to ON.

[skaluzka]

thanks for reply and clarifications. I confirm, it's enough to change src/boost.cmake file as below:

-  option(VERA_USE_SYSTEM_BOOST "Build boost" OFF)
+  option(VERA_USE_SYSTEM_BOOST "Build boost" ON)

[Gaëtan Lehmann]

pass python executable to boost build system - see #66

→ <<cset 83aa536839f9>>

[Gaëtan Lehmann]

Could you test with this last change? I think it should help, but have no arch linux to test.

[Gaëtan Lehmann]

I doubt 83aa536839f9 will be enough, but the last changes in the branch python-external-project should be good enough.

[skaluzka]

I confirm no more compilation errors. thanks!

[Gaëtan Lehmann]

great!
