This is a bug in libftdi v1.5 (apparently already present before),
regression triggered in Arch package 1.5-1 that adds the compile flag '-DFTDIPP=ON',
fixed mainline by commit cdb28383402d.

By adding flag '-DFTDIPP=ON' in PKGCONFIG both C and C++ version of libftdi are built.
The include files for C and C++ are installed in separate folders:
- /usr/include/libftdi1/ftdi.h
- /usr/include/libftdipp1/ftdi.hpp
but 'pkgconfig --cflags libftdi1' reports only the latter path:
-I/usr/include/libftdipp1 -I/usr/include/libusb-1.0
thus breaking the builds in C for packages (e.g. OpenOCD) that include <ftdi.h>.

The mainline fix installs both include files in the same folder.

Additional info:
* package version(s)
* config and/or log files etc.
* link to upstream bug report, if any;a=commitdiff;h=cdb28383402d248dbc6062f4391b038375c52385

Steps to reproduce:
Build OpenOCD with libftdi-1.5-1 installed and without libftdi-compat
git clone
cd openocd
Build halts with error due to missed include file ftdi.h
src/jtag/drivers/libftdi_helper.h:6:10: fatal error: ftdi.h: No such file or directory
It build correctly with libftdi-1.4-6 installed
This task depends upon

Actually the simple fix can be either adding the upstream patch cdb28383402d or removing the compile flag '-DFTDIPP=ON'.
I have no idea why the compile flag has been added in Arch package 1.5-1.

actually, `/usr/lib/pkgconfig/libftdipp1.pc` can be left alone.
only `/usr/lib/pkgconfig/libftdi1.pc` would need to be modified to include `/usr/include/ftdi1` (instead of `/usr/include/ftdipp1`.

sed -i 's@/usr/include/ftdipp1@/usr/include/ftdi1@g' $pkgdir/usr/lib/pkgconfig/libftdi1.pc

Looks like it is fixed in 1.5-2

Yes, I confirm 1.5-2 in testing fixes this issue.
Thanks, the ticket can be closed.
