Hello everyone, I have some problems with the example of the ir receiver on a Nanopi M1 usign the geany editor with the debian jessie 3.4.... provided by friendlyarm, I decided to modify the original demo program to match de embedded ir receiver but when I try to ececute the program, the information that I have until now is:

The version of geany is: 1.24.1

The response of the console when I try to run the program is:

./geany_run_script.sh: 5: ./geany_run_script.sh: ./Matrix-ir_receiver: Permission denied

 ------------------
(Program exited with code: 126)
Press return to continue

after that I press Enter and the terminal closes.

As you can see, I couldn't run the executable as root user, after that I saw properties of the program and noted that the permissions was set to "fa" on group "fa", changed all to root on group root it says:

root@friendlyELEC:/matrix/demo/matrix-ir_receiver# ./Matrix-ir_receiver
bash: ./Matrix-ir_receiver: cannot execute binary file: Exec format error

when I see the properties of the executable, it doesn't say "executable" in the file type but "object code" file type.

My commands are:

Compile:

gcc -Wall -c "%f"

Build:

gcc -Wall -c -o  "%f" "%e"

before that the command Build isn't had the -c option, it was added because the build command was giving me a lot of errors of the type "don't recognize several functions related to the I/O ports"

 

In other post a user told me to apply readelf -A <name of the file> and it gave this response:

Problem solved, it was a linker problem and I was drowning myself in a glass of water. I needed to add the -lfahw and -lm options to the build command, or I think add the makefile to the make command in geany. I don't know how to do the last yet.
