Hi
i am trying add wxt terminal support for gnuplot 4.6 in Slackware 14, as
gnuplot 4.6.0 package included does not support wxt and wxWidgets libs
are not included either.
I compiled wxPython-2.8.12.1. Now i can successfully compile and run
gnuplot 4.4.4 with wxt terminal.
but for gnuplot 4.6 (i tried both 4.6.0 and 4.6.1) compilation of wxt
teminal is not enabled. probably a relevant part from "config.log" file
goes below, and there are many errors like this
configure:YYYYY: -c++ -c -g -O2 -I/usr/include conftest.cpp >&5
./configure: line XXXXX: -c++: command not found
Am i doing anything wrong? GCC is 4.7.1.
thank you
Mikhail

The error message is perfectly clear.
You do not have a C++ compiler installed (or if you do then it's not in
the default path for execution).

Ethan, thank you for spending time on me.
I think i do have C++ compiler properly installed and in the default
path for execution, because gnuplot 4.4.4 can detect C++ compiler and
can be successfully compiled with wxt support on my system (i am now
using gnuplot 4.4.4 with wxt terminal). Can anything else be wrong?

Can anything else be wrong? So when you type "c++" at the command line you do get a compiler? Note that the usual name for the gcc C++ compiler is "g++" not "c++". I don't know why your system might be confused, but if "g++" works and "c++" does not, then you can probably proceed by doing (csh/tcsh) setenv CXX g++ ./configure or (bash/sh) export CXX=g++ ./configure > > Mikhail > > > On 26/12/2012 20:00, sfeam (Ethan Merritt) wrote: > >> configure:YYYYY: -c++ -c -g -O2 -I/usr/include conftest.cpp>&5 > >> > ./configure: line XXXXX: -c++: command not found > > [snip] > >> > configure:12223: WARNING: No C++ compiler found.

There is something subtle wrong with the compilation expression. It is constructing a command '-c++', not 'c++', and the command is treated as an option. Take a closer look at the configuration code to see how that extra dash in front is coming about.

i can see the following line inside the ./configure script
CXX=${CXX-${host_alias}-c++}
which can result in "-c++" as a name for C++ compiler binary assuming
empty $CXX and $host_alias. Not surprising, when running configure as
suggested by Ethan, "CXX=g++ ./configure", C++ compiler is detected
properly and wxt terminal is enabled, and compiled.

Strange construct. Given
AA=${BB-${CC}-c++}
it seems that if BB is defined AA ends up being BB. If BB is not
defined and CC is then AA is ${CC}-c++. If neither BB or CC is defined
then AA is -c++. Is the dash supposed to be similar to a conditional?

first dash is conditional, but the second must be literal in this notation.
i made some more trials. Slackware build script for gnuplot invokes
./configure with --build=i486-slackware-linux. If i omit setting --build
option, then C++ compiler is detected properly and gnuplot is built with
wxt terminal.
there are few more strange issues building 4.6 and some syntax changes
between 4.4 and 4.6 which must be taken into account before i can switch
to 4.6. so i give up and keep version 4.4.4 running for now.
thanks everyone for help.

OK, it is conditional. I did some tests here and the correct
construct/syntax appears to be the following:
AA=${BB-${CC-c++}}
It is easy enough to test at a shell command line by having BB/CC
defined and not defined in various combinations.

Don't give up. The change I suggested in the previous post should allow
you to build a little further. With "--build=i486-slackware-linux" then
'build' no longer is equal to 'host', and that is when the incorrect
conditional statement applies:
if test "${build}" != "${host}"
then
CC=${CC-${host_alias}-gcc}
CFLAGS=${CFLAGS-"-g -O2"}
CXX=${CXX-${host_alias}-c++}
CXXFLAGS=${CXXFLAGS-"-g -O2"}
CC_FOR_BUILD=${CC_FOR_BUILD-gcc}
By removing the "--build=i486-slackware-linux" I suspect you are no
longer doing a cross compile which may lead to other problems in
configure on your system.
Please change the following two lines
CC=${CC-${host_alias}-gcc}
CXX=${CXX-${host_alias}-c++}
to this
CC=${CC-${host_alias-gcc}}
CXX=${CXX-${host_alias-c++}}
and try configuring once again. Report back if there are further
issues. There appear to be some FIXMEs in the configure code that
probably haven't been resolved because no one has run across the issue
yet. You might be able to help.

Dan, i changed the CC= and CXX= lines in the ./configure script as you
suggested. now when invoking "./configure --build=i486-slackware-linux"
C++ compiled is detected successfully and wxt terminal is enabled.
i have a few minor issues, but these are 99.9% related to me running
slackware gnuplot build script as
su -c ./gnuplot.Slackbuild
because "su" command provides different PATH variable.
hope this is useful result.

I've applied that change to configure.in
Thanks both of you, and best wishes for the New Year.
