Arch Linux User Repository

@gOdil @walkingstickfan ok, thanks a lot to both of you, i updated the PKGFILE accordingly

I have the same Problem. This happens with the sed -i command. It happens whenever there are '/' chars in CFLAGS. I don't know, where they are coming (obviously from aurutils ...) from but for me, the sed commmand expands to

sed -i 's/-O2/-march=x86-64 -mtune=generic -O2 -pipe -fno-plt -fexceptions
         -Wp,-D_FORTIFY_SOURCE=3 -Wformat -Werror=format-security
         -fstack-clash-protection -fcf-protection
         -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer -g 
-ffile-prefix-map=/home/stefan/.cache/aurutils/sync/xzoom/src=/usr/src/debug/xzoom 
-flto=auto -Wl,-z,relro,-z,now/' ./Makefile

(on a single line)

To quote the '/' chars, I have updated the sed command in the PKGBUIKLD to

sed -i "s/-O2/$(sed -e 's/\//\\\//g' <<<"${CFLAGS}") -Wl,-z,relro,-z,now/" ./Makefile

which works for me.

@walkingstickfan The PKGBUILD contains no "sed -e" (just a "sed -i" at line 30), and here it builds and installs successfully on 4 of 4 different machines with Arch; can you please provide more context?

0.3-9 build fails...

sed: -e expression #1, char 266: unknown option to `s'

@m040601: ok, i updated the upstream URL and the source URL. Thank you! :-)

Nice little tool. Love it. Have on my system for years. Does what it does. Still works fine. Thanks for keeping up the PKGBUILD.

"Upstream" and "source" need update. https not http.

 Upstream URL:   ftp://sunsite.unc.edu/pub/linux/libs/X/
 9  url="ftp://sunsite.unc.edu/pub/linux/libs/X/"
13 source=("http://webdiis.unizar.es/pub/unix/X11/xzoom-0.3.tgz" "xzoom.diff")

$ curl -IL ftp://sunsite.unc.edu/pub/linux/libs/X/

curl: (7) Failed to connect to sunsite.unc.edu port 21 after 126 ms: Could not connect to server

$ curl -IL sunsite.unc.edu/pub/linux/libs/X/

HTTP/1.1 302 Found

$ curl -IL https://www.ibiblio.org/pub/linux/libs/X/xzoom-0.3.tgz

HTTP/2 200

So it is there on "https". That is the famous ibiblio mirrors, https://en.wikipedia.org/wiki/Ibiblio This should be the "Source". And https not http. And the homepage, "Upstream" should be https://www.ibiblio.org/pub/linux/libs/X/" if nothing better is found.

Although beware it's there on the ibiblio mirrors untouched since 2003

Ouch, and the files were last modified in 1996 !!!

Impossible to find the author "Itay Nahshon" on the Internet.

As an alternative, the only modern forks or repos I could find were.

https://github.com/mbarakatt/xzoom-follow-mouse

@gigamicro fixed, thank you! :-)

currently doesn't build; fixed by #include-ing <unistd.h> in xzoom.c

@badderman xzoom works the way it works, anyway under Xfce you can zoom in following mouse movement by pressing a key (default "alt", but it can be changed) and using the mouse wheel to zoom in and out; I suppose this can be done under Gnome and Kde too, in some way or another.

How to zoom in following mouse movement (Live Zoom Mode) instead of the fixed area? like MacOS or ZoomIt in Windows?

or

How to zoom in without showing own window like a transparent xzoom window?

Windows has solution with Magnification API:
