[Bug]: unable to build due to Vc on OpenBSD 7.6

[epsheldoni]

What happened?

I cloned the latest from github and after extracting it and adding a build directory and cd-ing to that directory, I type cmake ../ and there is scrolling on the erminal and I get the following

-- Build files have been written to: /home/sheldoni/Downloads/conky/build

and it stops. So I see that there is a makefile now in build and I type make and I get the following error

In file included from /home/sheldoni/Downloads/conky/build/3rdparty/Vc/trigonometric_SSE2.cpp:31: In file included from /home/sheldoni/Downloads/conky/3rdparty/Vc/Vc/vector.h:221: /home/sheldoni/Downloads/conky/3rdparty/Vc/Vc/scalar/math.h:118:7: error: no member named 'sincos' in the global namespace ::sincos(x.data(), &sin->data(), &cos->data()); ~~^ 1 error generated. Error 1 in . (3rdparty/Vc/CMakeFiles/Vc.dir/build.make:186 '3rdparty/Vc/CMakeFiles/Vc.dir/trigonometric_SSE2.cpp.o': cd /home/sheldoni/D...) Error 2 in .

Am I doing something wrong?

Am I doing something wrong?

Likely no. Do you mind providing the whole build log? It contains a lot of useful information and will reduce back-and-forth a lot.

[epsheldoni]

Where is the build log?

[Caellian]

You included the end of it in the issue.

Except yours ends with the error you already provided. Mine has a different error because I _did_ build conky incorrectly.

[Caellian]

Hmm interestingly enough, OpenBSD does have sincos is math.h (since 2018).

[epsheldoni]

I am still unable to successfully compile the latest from g0mb4. I get the same errors

[epsheldoni]

I cloned the latest from https://github.com/brndnmtthws/conky.git and I still get the same errors.

[Caellian]

2080 hasn't been merged yet, you'll need to clone from g0mb4's repo (https://github.com/g0mb4/conky) and checkout fix/openbsd76-build branch as it's not default.

[epsheldoni]

Thanks for the explanation. I downloaded the conky-fix-openbsd76-build and built it. After figuring out that it required the new format for .conkyrc, or conky.conf, I tried to run it and it crashes. Here is the terminal output

pangolin$ ./conky -d conky: desktop window (0x1a00003) is subwindow of root window (0x538) conky: window type - normal conky: drawing to created window (0x3000002) conky: drawing to double buffer conky: forked to background, pid is 33192 pangolin$ conky: FOUND: console conky: FOUND: ncurses conky: FOUND: file conky: FOUND: x11 conky: '(null)' (null) session running 'XFCE' desktop conky: Cannot get kern.cp_time conky: obj->data.i 2 info.cpu_count 1 conky: attempting to use more CPUs than you have!

I'm not sure how to proceed from here. I'll keep investigating.

Here is the output from sysctl | grep cpu

angolin$ sysctl | grep cpu kern.ccpu=1948 hw.ncpu=16 hw.sensors.cpu0.frequency0=1500000000.00 Hz hw.sensors.cpu1.frequency0=1650000000.00 Hz hw.sensors.cpu2.frequency0=1650000000.00 Hz hw.sensors.cpu3.frequency0=1600000000.00 Hz hw.sensors.cpu4.frequency0=1750000000.00 Hz hw.sensors.cpu5.frequency0=1850000000.00 Hz hw.sensors.cpu6.frequency0=1850000000.00 Hz hw.sensors.cpu7.frequency0=1850000000.00 Hz hw.cpuspeed=3300 hw.ncpufound=16 hw.ncpuonline=8 machdep.cpuvendor=AuthenticAMD machdep.cpuid=0xa70f41 machdep.cpufeature=0x179bfbff

Not sure if this helps but more information can't hurt.

[epsheldoni]

Here is a partial copy of the cpu lines in .conkyrc that causes it to crash

CPU 1 usage:$alignr ${cpu cpu1}% CPU 2 usage:$alignr ${cpu cpu2}% CPU 3 usage:$alignr ${cpu cpu3}% . down to CPU 15 usage $alignr ${cpu cpu15}%

Even if I only use one of the lines, it still crashes.

The following lines in the terminal output may indicate something OpenBSD specific

conky: Cannot get kern.cp_time conky: obj->data.i 2 info.cpu_count 1 conky: attempting to use more CPUs than you have!

[Caellian]

Thank you for very detailed information. I marked it as off-topic because it's not related to this issue, but I opened up #2088 for you and copied all relevant information there. That issue will probably wait for fix/openbsd76-build to be completed first to avoid having to rebase changes.
