libjpeg is missing

[inl-pd-autotest]

Xubuntu 16.10. Following README, on step ./conifgure I am getting this:

checking for jpeg_read_header in -ljpeg... no
Cannot find libjpeg or you have too old version (v6 or later required).

and can't follow to make because it says this:

make: *** No targets specified and no makefile found.  Stop.

@inl-pd-autotest Do this:
apt-get install libjpeg-dev
then try ./configure again

I'm having the same issue on Mac. What criteria is being used to determine if libjpeg is installed? I can confirm it is installed when I run brew install jpeg, but the jpegoptim installer can't see it for some reason.

Hi! I'm encountering the same issue positlabs described, on a M1 Mac. jpeg is installed using homebrew, but the ./configure fails with the error message described in this issue.

You can use option --with-libjpeg=DIR to tell where to look for libjpeg.

Something like:

./configure --with-libjpeg=$HOME/src/jpeg-9a

(assuming you have installed/compiled libjpeg in $HOME/src/jpeg-9a/)

If header files are in different directory vs where the (shared) library file is located at, you may need to specify those using environment variables CPPFLAGS and LDFLAGS.

Something like:

CPPFLAGS="-I /usr/local/include" LDFLAGS="-L /usr/local/lib" ./configure

@tjko Thank you! I managed to make it work using:

./configure --with-libjpeg=/opt/homebrew/Cellar/jpeg/9d
