qwt slackware 13.1 x86_64 [risolto]

[so_slack]

buon giorno,
Non e possibile compilare qwt - 5.2.1 in slackware x86_64 ?
non c'e un paquete x86-64?
grazie

Puoi usare lo SlackBuild su slackbuilds.org per crearti il pacchetto.

ho usato il pacchetto slackbuilds.org ma dice que non e per x86_64 (!)

Su slackbuilds.org non ci sono pacchetti, ma script SlackBuild per costruirseli. Devi scaricare l'archivio contentente i sorgenti del programma che vuoi compilare e l'archivio contenente lo SlackBuild. Successivamente, devi lanciare lo script da root per lanciare la compilazione e la creazione del pacchetto.
PS: from what you've written and how you wrote it, I guess you're not italian. If you're more comfortable with english speech, I can direct you to this tutorial on how to use SlackBuild scripts to build your own packages.
If you need further advice, feel free to ask.

yes i'm french
i know very well slackbuild , and i compile often. When i compile the library, using the slackbuild file i have this error

Ah, now I see.
I just tried using that SlackBuild and it seems to be written in the "old" slackbuilds.org format, the one which doesn't autodetect the ARCH you're building on.
Without the autodetection, the ARCH is set to i486 by default. That's why your compilation fails with these errors:

Codice: Seleziona tutto

erreur: le processeur selectionne ne supporte pas le jeu d'instructions x86-64

the build system is trying to build a i486 executable (32 bit) with a 64 bit compiler.
Try launching the SlackBuild like this:

Codice: Seleziona tutto

ARCH=x86_64 su -c ./qwt.SlackBuild

it should solve your issue.
Personally, I put this line in my ~/.bashrc:

Codice: Seleziona tutto

export ARCH=x86_64

in order to avoid specifying it manually every time.
Offtopic: Sorry if I misjudged your abilities with SlackBuild scripts before and if I replied in english, but my french is kinda rusty

[so_slack]

thank your for your help

but it don't work
do you have a x86_64 slackware version to test the compilation ?

[414N]

I just tried building it with the aforementioned SlackBuild, and it did build, indeed.
I modified the SlackBuild to build the latest stable version (5.2.1, as I saw from one of your previous posts it is the version you're interested in), to build on ARCH=x86_64 and I fixed some erroneus paths created by the make install step.

Please try this version and see if it works for you, now.

[so_slack]

yes with your version it's ok, thank you so much now i can compile qgis
mille grazie !

[so_slack]

ok now i try to compile qgis
i made a ldconfig
but i have this error
-- Found GSL: -L/usr/lib64 -lgsl -lgslcblas -lm
-- Found GEOS: /usr/lib64/libgeos_c.so

it's strange because i installed qwt ....

My fault.
It seems my SlackBuild puts the qwt shared library in /usr/lib64/lib/libqwt.so.5.2.1.
You can try moving it by hand for now in the correct location (/usr/lib64) and see if cmake complies with it again (run ldconfig before launching the build process for qgis).
If it works, I'll fix the SlackBuild I posted before.

[so_slack]

no i made
cp /usr/lib64/lib/libqwt.so.5.2.1 /usr/lib64
ldconfig

whereis libqwt.so.5.2.1
libqwt.so.5.2: /usr/lib64/libqwt.so.5.2.1

and
./qgis.SlackBuild

but same response
-- Found GDAL: /usr/lib64/libgdal.so
CMake Error at cmake/FindQWT.cmake:41 (MESSAGE):

[414N]

I think I found the culprit.
The template used by the CMakeLists.txt to find qwt tries to locate the shared library only in /usr/lib or /usr/local/lib, so it can't find it on Slackware64.
Try adding this line to the qgis SlackBuild just before cmake is launched:

Codice: Seleziona tutto

sed -i 's|/usr/lib|/usr/lib${LIBDIRSUFFIX}|g' cmake/FindQWT.cmake 

The library should be found now.

[so_slack]

like this ?
sed -i 's|/usr/lib|/usr/lib${LIBDIRSUFFIX}|g' cmake/FindQWT.cmake

cmake . \
-DCMAKE_C_FLAGS:STRING="$SLKCFLAGS" \
-DCMAKE_CXX_FLAGS:STRING="$SLKCFLAGS" \
-DCMAKE_INSTALL_PREFIX=/usr \
-DQGIS_LIB_SUBDIR=lib${LIBDIRSUFFIX} \
-DQGIS_LIBEXEC_SUBDIR=lib${LIBDIRSUFFIX}/qgis \
-DQGIS_PLUGIN_SUBDIR=lib${LIBDIRSUFFIX}/qgis \
-DWITH_MAPSERVER=FALSE \
$WITHGRASS

it don't work
i tried to copy the file in /usr/lib but same problem

[414N]

Today is a bad day
I forgot to change the single quotes in the command with the double quotes.
So it should be like this:

Codice: Seleziona tutto

sed -i "s|/usr/lib|/usr/lib${LIBDIRSUFFIX}|g" cmake/FindQWT.cmake
