getting error while go get github.com/pixiv/go-libjpeg/jpeg

# github.com/pixiv/go-libjpeg/jpeg
go/pkg/mod/github.com/pixiv/[email protected]/jpeg/compress.go:6:10: fatal error: jpeglib.h: No such file or directory
 #include "jpeglib.h"
          ^~~~~~~~~~~
compilation terminated.

The above block appears while executing go get, any idea what to do next.
Any help would be appreciated.
Best regards

@ashu171996 you have to specify location of the header file (also I guess the library).
You do that by setting CGO_LDFLAGS and CGO_CPPFLAGS variables
See similar issue

@ashu171996
'sudo apt-get install libjpeg-dev' should solve your issue :-)

For mac e.g. brew install jpeg helps to retrieve the neccessary includes and libs.
Running e.g. CGO_LDFLAGS="-L/opt/homebrew/Cellar/jpeg/9d/lib -lm" CGO_CPPFLAGS="-I/opt/homebrew/Cellar/jpeg/9d/include" go get github.com/pixiv/go-libjpeg would be able to load the package.
Adjust the version (9d) if it has changed.

Edit:
It's also possible to just use CGO_LDFLAGS="-L/opt/homebrew/lib -lm" CGO_CPPFLAGS="-I/opt/homebrew/include" go get github.com/pixiv/go-libjpeg

Or executing in your shell: export CPATH=/opt/homebrew/include export LIBRARY_PATH=/opt/homebrew/lib or adding it to your shell rc file.
