thumbnailer: Errors when updating to the newest version

Hello, I just updated to the newest version and I get a bunch of error messages when I try to start my go application now. Everything was working perfectly fine before the upgrade.

This is the list of all error messages:

Can anyone help me with this? I just don’t know what to do.

Hello bakape. I switched to a linux envrionment now and when I try to run/build my app, I get following error message:

# github.com/0xSeven/thumbnailer
/usr/bin/ld: /usr/local/lib/libGraphicsMagick.a(magick_libGraphicsMagick_la-shear.o): undefined reference to symbol 'trunc@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libm.so.6: error adding symbols: DSO missing from command line

I don’t know what to do anymore, I tried everything I can to get this thing running. Please bakape, I beg you for help or hints. I’m just a go noob who tries to launch his first go app on an amazon ec2. Please, sir.

Are you cross-compiling?

I changed some dependencies. You need a C++17 compiler and GraphicsMagick++ installed on your system.
