LDFLAGS+= -fPIC and LIBS += -lrt -lpthread doesn't work via debian/rules at Launchpad

Thank you for taking the time to report this issue and helping to make Ubuntu better. Examining the information you have given us, this does not appear to be a bug report so we are closing it and converting it to a question in the support tracker. We understand the difficulties you are facing, but it would make more sense to raise problems you are having in the support tracker at https://answers.launchpad.net/ubuntu or ask at http://askubuntu.com/ if you are uncertain if they are bugs. For help on reporting bugs, see https://help.ubuntu.com/community/ReportingBugs.

in this case your build system is broken in many places. e.g. usbredirserver/Makefile uses -Wl,-rpath-link which requires you to use pkg-config --static libusb-1.0 to get all libraries and libusb-1.0 must be built with -fPIC which it is currently not in the packages in your ppa.

I've updated

usbredirhost/Makefile as follows :

override CPPFLAGS += $(shell pkg-config --cflags libusb-1.0-rc1)
LIBS_libusbredirhost = $(shell pkg-config --libs libusb-1.0-rc1)

usbredirserver/Makefile as follows

override CPPFLAGS += $(shell pkg-config --cflags libusb-1.0-rc1)
LIBS = $(shell pkg-config --libs libusb-1.0-rc1)

debian/control

Build-Depends: debhelper (>= 8.0.0),
               autotools-dev,
               pkg-config,
               quilt (>= 0.40),
               libusb-1.0-rc1,
               libusb-1.0-rc1-dev
System is expected libusb-1.0-rc1 installed on Ubuntu , not to be just in PPA ( it's there)

https://launchpadlibrarian.net/81106021/buildlog_ubuntu-oneiric-i386.usbredir_0.3.1-1ubuntu2_FAILEDTOBUILD.txt.gz

It just cannot find library,suggesting to change PKG_CONFIG_PATH.

That's a mistake. I used name of package instead of library.
Disregard previous statement.

> libusb-1.0 must be built with -fPIC which it is currently not in the packages in your ppa.

I believe libusb-1.0 ( v. 1.0.9-rc1) is in package libusb-1.0-rc1 which is in the PPA.

Procedure bellow locally run just fine on beta-2 +

Per Hans de Goede

*** Step 1 Building libusb ***

First of all you will need libusb from git for now, hopefully there will soon be an offfical 1.0.9 release you can use instead. To build libusb from git do:

git clone git://people.freedesktop.org/~jwrdegoede/libusb
cd libusb
git checkout -B for109 origin/for109
./autogen.sh
./configure --prefix=/usr --libdir=/usr/lib/x86_64-linux-gnu
make -j2
sudo make install

*** Step 2 building usbredir ***

Next you will need to build usbredir itself for the usbredirparser and usbredirhost libraries, download it here, then do:

tar xvfj usbredir-0.3.1.tar.bz2
cd usbredir-0.3.1
make -j2 PREFIX=/usr LIBDIR=/usr/lib
sudo make PREFIX=/usr LIBDIR=/usr/lib install

Attempt to package into https://launchpad.net/~bderzhavets/+archive/libusb-test2
gives the same results as above

All what we have locally after Step 1 :

which one i cannot find locally

And after Step 2 :

./usr/lib64/libusbredirparser.so.0
./usr/lib64/libusbredirhost.so
./usr/lib64/libusbredirparser.so
./usr/lib64/libusbredirhost.so.1

Regardless debian/rules has LIBS += -lrt -lpthread

I would consider this already as system bug

no the Makefile.rules does not use the LIBS variable, instead it uses LIBS_somename.
Either fix that to use LIBS or do this:
