Dear jngl,
welcome to the Cafu forums!
This looks like the wxWidgets library could not be build in a prior step in the compilation, and unfortunately (but knowingly) SCons did not abort at that earlier error, but only subsequently when it was trying to link in the (never completed) wxWidgets library.
Did you install all the packages mentioned in section "Linux packages" in article
Getting Started with the Cafu Source Code?
If so, please delete directories
build-gtk_d and
build-gtk_r, that is, run
Code: Select all
rm -rf ExtLibs/wxWidgets/build-gtk_d
rm -rf ExtLibs/wxWidgets/build-gtk_r
then re-run SCons.
If it again fails to build, please find in the output and post here the first error message where wxWidgets has a problem. Thanks!
