| Summary | 0000519: extras/graphics/mercury_tcltk library may contain reference to unknown matherr symbol | ||||||||
| Description | mtcltk.m contains the following: /* ** The following variable is a special hack that is needed in order for ** Sun shared libraries to be used for Tcl. */ :- pragma foreign_code("C", " extern int matherr(void); int *tclDummyMathPtr = (int *) matherr; "). This workaround is no longer necessary with modern versions of Tcl and the matherr() function has been removed since version 8.4. [1] While libmercury_tcltk.so may be built, the resultant library may cause problems. For example, after building extras/graphics/mercury_tcltk: $ cd extras/graphics/samples/calc $ mmc --search-lib-files-dir ../../mercury_tcltk --library mercury_tcltk --make calc <snip> Making calc ** Error making 'calc'. ../../mercury_tcltk/libmercury_tcltk.so: undefined reference to 'matherr' collect2: error: ld returned 1 exit status We could either just remove the workaround or perhaps wrap it in some ifdef/endif block.

I've deleted it; I'm pretty sure we don't care about versions of Tcl from before 1999 any more. |
