The error shown in the log is:

:info:build ./../src-IL/src/il_jp2.c:462:23: error: expected expression
:info:build                         stream->bufbase_ = JAS_CAST(uchar *, buf);
:info:build                                            ^

Evidently, libdevil 1.7.8 is not compatible with the current version of jasper.

DevIL is an old graphics library that was abandoned, forked to ResIL, abandoned again, and then revived as DevIL again. 1.8.0 is available and I have begun trying to update the port to that version.

hello:

any news about this?

Thanks

The file il_jp2.c uses an outdated declaration 'uchar'. In line 462 as cited above, replace 'uchar' by 'jas_uchar', which is the current type declaration for bufbase_ in jas_stream.h.

After replacement, the line should read:

stream->bufbase_ = JAS_CAST(jas_uchar *, buf);

libdevil: allow build with latest version of jasper

No revbump because port either builds correctly or not at all.
Fixes #53852
