gnuplot-4.2.rc1: --program-suffix and gnuplot_x11

[Reiner S. <rei...@im...>]

Hi,

I tried to install gnuplot-4.2.rc1 on GNU/Linux (SUSE 9.2) on both
i686 and x86_64.

I want to install gnuplot to /usr/local which is shared between i686
and x86_64 machines.  Therefore, I compile and install it using
"--program-suffix" as follows:

--8<---------------cut here---------------start------------->8---
#!/bin/sh
conf_1="--enable-history-file --with-readline=gnu --enable-mouse"
suffix="4-2-rc1-`uname -m`"
set -e
./configure --program-suffix=-"$suffix" --prefix=${SOFT:-/usr/local} $conf_1
rm src/*.o
make
make install
--8<---------------cut here---------------end--------------->8---

I get:

,----
| /usr/local/libexec/gnuplot/4.2$ ls
| gnuplot_x11-4-2-rc1-i686  gnuplot_x11-4-2-rc1-x86_64
| 
| /usr/local/bin$ ls gnuplot-4-2-rc1-*
| gnuplot-4-2-rc1-i686  gnuplot-4-2-rc1-x86_64
`----

In /usr/local/bin, I have the following tiny wrapper:

,----[ gnuplot-4-2-rc1 ]
| #!/bin/sh
| exec "$0-`uname -m`" "$@"
`----

When I run gnuplot under X11, I get:

,----
| /usr/local/bin$ ./gnuplot-4-2-rc1-x86_64
| Expected X11 driver: /usr/local/libexec/gnuplot/4.2/gnuplot_x11
| Exec failed: No such file or directory
| See 'help x11' for more details
`----

,----
| $ ./gnuplot-4-2-rc1-i686

I'd say this is a bug: Either the installation routine should install
gnuplot_x11 as libexec/gnuplot/4.2-${program_suffix}/gnuplot_x11 or
the main program should search for
/usr/local/libexec/gnuplot/4.2/gnuplot_x11-4-2-${program_suffix} as
well.

BTW, I can work around this problem with...
,----
| cd /usr/local/libexec/gnuplot/4.2
| ln -s gnuplot_x11-4-2-rc1-i686 gnuplot_x11
`----
...  but this only works accidentally for i686 and x86_64.

Bye, Reiner.
