I'm attempting to work with the FX7500 RFID reader and need to develop an app for the reader that does a seemingly simple thing ... it just needs to read tags and POST to a URL. Sounds simple enough, or so I thought.
I followed the C embedded SDK instructions, installed the SDK DEB package. Launched Eclipse and so far everything was going according to the instructions in the SDK guide. However, I am encountering a problem when trying to build the RFIDSample4App-C project. I have not been able to find any information about this error, so I'm turning here to this developer community to ask for your help and/or guidance on how to resolve this issue.
When I click "build project" in Eclipse, the result is "Build Failed. 2 errors, 507 warnings."
I think I can ignore the warnings, even though they are unexpected. The documents say nothing of these warnings or errors.
The two errors are:
/usr/share/Zebra-FXSeries-Embedded-Native-SDK-C-CPP_Linux/tools/armhfp-gnueabi/bin../libexec/arm-montavista-linux-gnueabi/gcc/arm-montavista-linux-gnueabi/6.4.0/ld: cannot find -l/usr/share/Zebra-FXSeries-Embedded-Native-SDK-C-CPP_Linux/RFID_C_API/lib/librfidapi32.so
make: *** [makefile:33: RFIDSample4App-C] Error 1
I do not however see the problem, because librfidapi32.so is present at that path. What could the problem be? Has anyone encountered this before?
I am using Ubuntu 20.04 on Hyper-V
Any help is greatly appreciated. It seems like reading tags and posting to a URL is a function/feature which should already exist, but also I'm not experienced in C development on Linux, so I think this is going to be a bit tough for me to pull off. Alternatively, does anyone know of any existing 3rd party apps or examples for how to accomplish this? I'm kinda stuck without any help here, so thank you in advance!
