[SOLVED] I can't compile cwm under slackware64-current

moisespedro · 08-27-2014, 01:49 PM

After a few months without using Linux I decided to go back to it and I am using slackware64-current fully patched. I am trying to compile cwm using sbopkg (I already configured it to current) and I am getting this:

Code:

I searched a bit and from what I've found it has something to do with freetype2 but I am not sure on what to do.

Check the header call in the file and match it to the actual header path. See where in /usr/include ft2build.h is located.

In package freetype-2.5.0.1 shipped on Slackware64-14.1 ft2build.h was in /usr/include, but in package freetype-2.5.3 now shipped in Slackware64-current, it is in /usr/include/freetype2.

As a workaround you could copy or link it in /usr/include

Be aware that SlackBuilds @ http://slackbuilds.org are not intended to be used on -current, so in my opinion if you run -current you should be prepared to deal with this kind of change in packaging.

More generally, if you want to use many third party SlackBuilds and unless you want to help iron out incoming Slackware release, my advice is to stick with the current -stable version.

PS It seems that there be an incompatibility between freetype-2.5.3 and libXft-2.3.2 but that's another topic.

I found the file at "/usr/include/freetype2/ft2build.h". I went then to calmwm.c, saw that it calls/includes calmwm.h went to it and I couldn't find where I should edit it. From what I understood the calmwm.h file includes <X11/Xft/Xft.h> anda that is the file I should edit. But I don't think that would be the best approach, it is a system file and it would be replaced on upgrades, etc.

EDIT: I didn't think about a symlink, I will do that
EDIT2: After creating a bunch of symlinks for the freetype2 headers the compilation went fine.

Edit the path for ft2build.h in the source as such:

#include <freetype2/ft2build.h>

...or just add a CPPFLAGS line before the make block, like

Code:

CPPFLAGS="-I/usr/include/freetype2" \
CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \
PREFIX=/usr \
MANDIR=/usr/man \
DESTDIR="$PKG" \
make install

Oh, definitely two solutions way better than mine. Thanks folks.

In case anyone's interested, there is another port of cwm by Christian Neukirchen that I've always been using (did not even know there was another port besides his …). It compiles cleanly on -current and uses pkg-config:
https://github.com/chneukirchen/cwm

edit: I've just submitted a SlackBuild for Christian's cwm version/port. I hope it will get accepted.

edit2: It will be available with the next update.
