[SOLVED]Help installing Powertop2 from AUR.

Hello,

I get following error while building from Powertop2 from AUR. Their are a few explanation/solution that I have no idea what to do about it. I have requested help but have not received so far. So, I am posting it here. Please help.

My Error

@thestinger

The errors occur because gcc 4.7 removed a lot of unnecessary includes from the standard library headers.

You need to #include <unistd.h> in all the files that fail to compile.

With the addinclude utility, you can just do:

$ addinclude failing_file.cpp unistd

Thanks @thestinger. I had to add the following lines to PKGBUILD:


addinclude main.cpp unistd
addinclude -t html.cpp unistd
addinclude devices/device.cpp unistd
addinclude cpu/intel_cpus.cpp unistd
addinclude devices/alsa.cpp unistd
addinclude devices/rfkill.cpp unistd 
addinclude devices/i915-gpu.cpp unistd
addinclude devices/thinkpad-fan.cpp unistd 
addinclude devices/network.cpp unistd
addinclude devices/thinkpad-light.cpp unistd

ATTENTION: For some reason I had to use -t parameter for the file html.cpp, otherwise the include statement was somewhere in the file...

Thanks.

Hi there

You build powertop using yaourt? If yes, you need answer "yes" when yaourt offer you to edit PKGBUILD. Then add lines between "patch" and "make". The part of PKGBUILD should look like this:

patch -p1 < ../powertop-1.98-sysfs.patch
patch -p1 < ../Makefile.patch

addinclude main.cpp unistd
addinclude -t html.cpp unistd
addinclude devices/device.cpp unistd
addinclude cpu/intel_cpus.cpp unistd
addinclude devices/alsa.cpp unistd  
addinclude devices/rfkill.cpp unistd
addinclude devices/i915-gpu.cpp unistd
addinclude devices/thinkpad-fan.cpp unistd
addinclude devices/network.cpp unistd
addinclude devices/thinkpad-light.cpp unistd

make

Thanks @Copycat

Andrwe at AUR has already helped me with the issue without addinclude.

Hi,

add the following code above of 'make' within the build()-function:

for file in main.cpp html.cpp devices/{device.cpp,alsa.cpp,rfkill.cpp,i915-gpu.cpp,thinkpad-fan.cpp,network.cpp,thinkpad-light.cpp} cpu/intel_cpus.cpp
do
sed -i 's/\(#include .*\)/#include <unistd.h>\n\1/' "${file}"
done

That's a dirty hack which does in general the same as addinclude but you don't have to install addinclude.


Regards,
Andrwe
