Error in build:

PKGBUILD: line 15: cd: /tmp/jpegtran_crop/src/jpegcrop/jpeg-9d: No such file or directory

The checksum seems to be wrong.

@Maniaxx if you check https://aur.archlinux.org/packages/libjpeg9 you'll find that it also contains /usr/lib/libjpeg.so.9. And libjpeg-turbo updating to v9 seems very unlikely: https://libjpeg-turbo.org/About/Jpeg-9

In a nutshell, The libjpeg-turbo Project has decided to use the release of 
jpeg-9 as an opportunity to draw a line in the sand and say "enough!" We could 
emulate the libjpeg v9 API/ABI easily enough, but why? The only purpose would be 
to support applications or O/S distributions that had upgraded from jpeg-8 to 
jpeg-9, but it is our opinion that no technical justification exists for this 
upgrade. 

Also it seems to be quite a lot of bad blood between the projects..

Not sure. It might work if jpgtran asks for libjpeg.so.9 specifically. But you'll get into trouble once libjpeg-turbo updates to v9 as well. I'm wondering why they haven't done so already. Maybe ask the officials how to deal with this.

@Maniaxx thanks for sharing. please let me know what you think about this:

How is this meant to be installed without breaking the dependency tree? extra/libjpeg-turbo has too many dependencies to get uninstalled here.

Edit: As a workaround i've compiled it statically:

./configure
make DESTDIR=/tmp/jpegtran LINK='$(LIBTOOL) $(AM_V_lt) --tag=CC $(AM_LIBTOOLFLAGS) $(LIBTOOLFLAGS) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) $(AM_LDFLAGS) $(LDFLAGS) -all-static -s -o $@' -j4 install

@Nowaker

there is a difference between jpegtran from libjpeg-turbo and this PKGBUILD. namely libjpeg-turbo supports -icc switch but it is lacking support for:

-drop +X+Y filename Drop another image
-scale M/N          Scale output image by fraction M/N
-wipe WxH+X+Y       Wipe (gray out) a rectangular subarea

If you want to build this, change 9b to 9d in both the PKGBUILD & .SRCINFO files.

Please note that this package also conflicts with extra/libjpeg-turbo
