Error installation cannot find -lvalaccodegen

[liorko87]

Hello,

I'm trying to install radare2-bindings on CentOS 7 machine. I followed the instructions at the README and received this error:

In file included from /usr/include/glib-2.0/glib.h:50:0,
                 from /home/centos/valabind/gowriter.c:6:

             ^
/usr/bin/ld: cannot find -lvalaccodegen

what is missing at my installation?

[radare]

If you are using an old version of vala you should use an old version of valabind.

Which version of vala are you using?

I'm using the latest version of vala. I download it from vala official site at this link

[radare]

Latest valabind expects vala from git. So its not the last.

Can you paste build logs?

At the instructions you are pointing to install vala from tarball and from source, so I installed both of them.

[radare]

Valabind cant be compiled with vala 0.38.4 because the internal compiler APIs are compiled statically and not available to link against,, you may use the last unstable release 0.39.x or wait for 0.40 that may appear soon, for now i would opt for vala from git.

Ive been discussing with the vala devs because of the inabiilty to build valabind, and thats why i had to split the build steps.

I deleted vala 0.38.4 from my machine, and installed the vala from git. I'm working on branch master of vala, but I'm still getting the same error.

[mckuok]

Same problem here. Does anyone have a fix?

[radare]

Ther s no fix. Vala is not exposing any of the internal apis that are required for valabind to work. Other projects like valadoc are also affected.

The only possible fix is use old version of vala or latest unstable release or git

@radare Which version of Vala (https://wiki.gnome.org/Projects/Vala/Release) do you recommend us to install?

Edit: I tried with 0.39.5 and got passed the missing valaccodegen error

[radare]

Last unstable or git. See the travis.yml from valabind

Yes. Its just up to the distros to upgrade vala
