Trouble compiling Celtx from source (canvas)

[ReaphSharc]

Hi, been trying to compile Celtx from source (on a 32-bits system), but no luck yet...
I do:

Code: Select all

# cp mozconfig-nodebug-linux .mozconfig
# make distclean
# make -f client.mk build

I get:

Code: Select all

Most compiles I try, including ones where I don't use the mozconfig file and ./configure by hand with my own flags and options seem to choke on 'canvas'.

Suggestions and solutions are welcomed

Hi ReaphSharc,

Is it possible you have -Werror set by default for your compiler? Neither of those messages ("type-punned pointer" and "defined but not used") are errors, they are simply warnings, and shouldn't interrupt the build unless gcc is set to treat warnings as errors.

Is there more of that build log you can post, perhaps another 20-40 lines? It's possible there's an actual error message further up and the warning messages are just red herrings.

Don't think -Werror set by default. But here's a few extra lines:

Hmmmm, looks like a few errors with a pangocairo library?

Hi ReaphSharc,

You could try adding "ac_add_options --enable-system-cairo" to your .mozconfig file. No guarantee that'll fix it, but it's worth a try.

What Linux distribution are you using to build? Fedora?

Thanks for the help, that did the trick.
I'm building Celtx for ArchLinux, and specifically I'm working on an install script for our Arch User Repository. I've already put the binary build in there, but that doesn't work for the 64-bit system owners. So now I want to supply our community with both a binary (32-bits) package and a source package.
