| Subject: | Configuration fails on debian systems with libjpeg62-turbo installed |
On a debian/jessie system with libjpeg62-turbo-dev installed:
$ perl5.22.2 Makefile.PL
Unable to read /usr/include/jconfig.h
Problem is that jconfig.h is in an architecture-dependent directory, unlinke jpeglib.h and the other header files:
...
/usr/include/jpeglib.h
/usr/include/jmorecfg.h
/usr/include/jerror.h
/usr/include/jpegint.h
/usr/include/x86_64-linux-gnu/jconfig.h
...
I tried a workaround to this problem (see patch below) --- this helps to get me through the configuration and build phase, but tests fail. I think the problem here is that the jpeg version is 62, but the generated images do not match.
Regards,
Slaven
