fwriteUTF8() information

[Andrew H]

Hi,

I am trying to build ocropus 0.4.3 on FreeBSD 7.2. Compiling stops
when it hits buildhtml.cc with the following error:

g++ -DPACKAGE_NAME=\"ocropus\" -DPACKAGE_TARNAME=\"ocropus\" -

I've done some looking and the only mention I could find of the
fgetsUTF8() and fwriteUTF8() functions are from the Ocropus project
itself, so that's not much help. I know Ubuntu is the target platform,
but I couldn't even find any information on it on that platform.

Does anyone have any pointers on how to fix this? That would be most
appreciated.

I'm not sure what the problem is. It could be a problem with the
compiler version, the build system, or anything else.

Try building with scons and make sure that you're using a recent
version of gcc (preferably 4.4).
