GPM patch for glibc-2.26/gcc-7.2.0

[Douglas R. Reno]

I've had two people who were trying GPM report this issue to me, and upon scouting upstream, I found an issue by our very own 'tnut':

Try tnut's patch here, and adapt:

Seems that sed -i s/__sigemptyset/sigemptyset/ src/prog/gpm-root.y and sed -i s/__sigemptyset/sigemptyset/ src/daemon/openconsole.c could do. See ​Riccardo Corsi's mail. But tnut's patch is more complicated. I'll try soon...

[Pierre Labastie]

Replying to pierre.labastie:

Seems that sed -i s/__sigemptyset/sigemptyset/ src/prog/gpm-root.y and sed -i s/__sigemptyset/sigemptyset/ src/daemon/openconsole.c could do.

This is not enough... The patch allows to build.

[Pierre Labastie]

With the patch, gpm is built and runs OK.
