I installed the FREngine using the installer script:
Creating directory FREngine-Linux-x86_64-184.108.40.2066527
Verifying archive integrity... All good.
Install at /opt/ABBYY/FREngine11?(y/n) n
Input installation directory: /home/bwss/tmp/fre11/install
1) Developer installation
2) Runtime installation
Fine Reader Engine is installed but not activated.
Launch /home/bwss/tmp/fre11/install/activatefre.sh as root user to complete activation process
So I selected a custom install directory and choose to install the developer installation. After this I tried to compile some of the samples, but the compilation fails because there is no SampleConfig.h.
../SharedTools/FREngineLoader.cpp:13:30: fatal error: ../SamplesConfig.h: No such file or directory
make: *** [FREngineLoader.o] Error 1
And indeed there is none. What is this file and why is it missing?
