cc: error: /opt/mozjpeg/lib/libjpeg.a: No such file or directory

[csdougliss]

Build system is Ubuntu 16.04, 64-bit.

uname -m

x86_64

/opt/mozjpeg/lib64 is installed but not in lib as below, hence the error?

I only recently had this error, but I haven't rebuilt in a long time.

I symlinked lib64-> lib and it solved my problem.

Thanks to @shanemhansen You just need run sudo ln -s /opt/mozjpeg/lib64/ /opt/mozjpeg/lib

Should be fixed by 2764fca (Link against lib64 mozjpeg on multi-arch systems, 2018-05-15).
