I'm trying to build a shared library to use on a raspberry pi (model 3B) using lazarus. After some puzzling I found out that my original library didn't work properly so I switched to a very simple library using this example.
But even this simple library doesn't compile properly to be used. When I try to open the library in another lazarus project it gives me the error:
< libName >: cannot open shared object file: No such file or directory
After some research I found the following diagnostics I could run. The file and ldd command in the compile library:
$file ./libname.so gives:
./libname.so: ELF 32-bit LSB shared object, ARM, EABI5 verion 1 (SYSV), dynamically linked, not stripped
$ldd ./libname.so
not a dynamic executable
I have searched for similar cases and from found that others had this problem when they tried to use libraries compile for a different platform/architecture. I already set the project>project options>compiler options>target platform to OS:= linux and Target CPU family: arm.
The system I am using (using $uname -a):
Linux raspberrypi 4.4.13-V7+ #894 SMP Mon Jun 13 13:13:27 BST 2016 armv7l GNU/Linux
with distro: Raspbian GNU/linux 8.0 (jessie)
Lazarus version: 1.2.4+dfsg2-1 FPC version: 2.6.4 arm-linux-gtk2
At this point I am not sure what is wrong and why this library isn't working. I can find very little information on this problem (on the aspberry platform and using lazarus) Any suggestions what I could try to make it work, compile it different or do some more diagnostics?
