cannot compile: undefined reference to `crypt'

[pauledd]

Hi @magnue
I just changed from gentoo to a fresh Ubuntu Mate in my RPi2 but now I am not able to compile
indi_wiringpi_gpio anymore. I followed exactly you instructions but sudo make install failes with:

...
[ 83%] Building CXX object CMakeFiles/indi_wiringpi_gpio.dir/wiringpi_gpio/wiringpi_updater.cpp.o
[100%] Linking CXX executable indi_wiringpi_gpio
/usr/local/lib/libwiringPi.so: undefined reference to `crypt'
collect2: error: ld returned 1 exit status
CMakeFiles/indi_wiringpi_gpio.dir/build.make:200: recipe for target 'indi_wiringpi_gpio' failed
make[2]: *** [indi_wiringpi_gpio] Error 1

make[1]: *** [CMakeFiles/indi_wiringpi_gpio.dir/all] Error 2
Makefile:127: recipe for target 'all' failed
make: *** [all] Error 2

any ideas what might be wrong with wiringPi?

it has to be compiled with "-L" flag but I have no clue how to implement this in this cmake thing...

problem solved somehow by adding "crypt" to this line in CMakeLists.txt
target_link_libraries(indi_wiringpi_gpio ${INDI_DRIVER_LIBRARIES} ${WIRING_PI_LIBRARIES} crypt)

It compiles now fine but sadly I hit my prevous issue #1 again. I think there is something totally broken with indi_wiringpi_gpio and I consider to change my hardware to use usb relay.

issue #1 solved again by doing my stupid fix from here:
http://indilib.org/forum/embedded-indi/2477-help-on-indi-wiringpi-gpio-crash.html?start=12#18546
I somehow forgot to apply this fix into my fork of this repo...
I stay with indi_wiringpi_gpio if no further problems pop up...
closed...

Isuue fixed in commit 89bb502
