cross compile to arm, 32bit, is missing libXtst.so lazarus / 1-Linux ---------------------------------------------------------------------- att2 · 2019-07-27 12:15 Hello, I can cross compile my project fine on a virtual Linux Mint 19 machine to aarch64/linux. I cannot cross compile to arm, 32bit, because one library is missing: /home/arm1/fpc2/cross/lib/arm-linux is missing the file "libXtst.so". Where to get this file, how to make it? The lazarus is version 1.8.4 , the compiler is fpc 3.2.0 Any advice greatly appreciated. Just doing "sudo apt-get install libxtst-dev" on the virtual machine did NOT help. ---------------------------------------------------------------------- af0815 · 2019-07-27 12:31 you habe to get the libs from the targetmachine eg. RasPi.
