Created attachment 525312 [details, diff] tk707-0.8-glibc227.patch The problem is not GCC-7 related. It's due to ~sys-libs/glibc-2.27. From https://lists.gnu.org/archive/html/info-gnu/2018-02/msg00000.html: > libm no longer supports SVID error handling (calling a user-provided > matherr function on error) Furthermore, from https://wiki.tcl.tk/3577: > If you've ever built a custom tclsh or wish, you may have inherited the > following bit of code that first appeared in the tclAppInit.c file in Tcl 7.4: > > | /* > | * The following variable is a special hack that is needed in order for > | * Sun shared libraries to be used for Tcl. > | */ > | > | extern int matherr(); > | int *tclDummyMathPtr = (int *) matherr; > > If so, you should take it out. > The original reason for this special hack has been lost in the sands of time, > but it is definitely no longer needed on current versions of Solaris or any > other modern Unix. The tk707 project appears to have been dead since 2005 and would be a good candidate for removal. Otherwise, this patch just removes the problematic and outdated code.
