I am trying to setup BLE-Mesh Provisioner on my Ubuntu NUC. Since kernel is already build in NUC Ubuntu with version 4.15.0-76 generic. Now I am trying to compile Bluez from source. I have performed following steps on my system:
Compiling dependency needed for bluez
Installing Json-library and Embedded Linux Library
Compiling Bluez
While compiling I am getting an error as:

I am following this reference to setup Bluez in system:
https://budimir.cc/2022/01/08/compile-bluez-from-source/
Please help me to resolve this problem while setting up bluez on Ubuntu.
I am expecting the exact solution or guide. How to set up Bluetooth-Low-Energy on Ubuntu. Basically when I was trying with Raspberrypi I was not able to install pygattlib and pybluez .. So I switched to Ubuntu and now I am expecting that there would be solution to resolve this issue. Please help me to resolve this issue
I'm trying to cross compile GPG for an ElinOS on a board with an imx6. I have a problem when I compile libgcrypt. First, here's what I do:
export PATH=/opt/elinos/cdk/arm/v7hf/glibc/bin:$PATH
./configure --host=arm-unknown-linux-gnueabihf --build=i686-pc-linux-gnu
make all
The configuration part shows no errors or warning, but the make displays this:
hwf-arm.c:31:3: error: #error Module build for wrong CPU.
# error Module build for wrong CPU.
^
hwf-arm.c: In function 'get_hwcap':

The first error leads me to this part of the code :
#if !defined (__arm__) && !defined (__aarch64__)
# error Module build for wrong CPU.
#endif
Any idea where this comes from? It looks like a configuration problem, but I'm not sure where to look now.
In the config.log file, CC was setup correctly: CC='arm-unknown-linux-gnueabihf-gcc'.
Yet I needed to specify it in the make command. So instead of simply using make all, which didn't work, I had to use make all CC=arm-unknown-linux-gnueabihf-gcc.
I am facing an issue with the execution of following Groovy Script snippet.
GroovyShell sh = new GroovyShell();
sh.evaluate("\"abcd\".length() >= .34");
I am getting the following exceptions. The entire stack trace is mentioned below.
Exception in thread "main" org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script1.groovy: 1: unexpected token: >= # line 1, column 17.
"abcd".length() >= .34d
If I change .34 to 0.34, it works. However, because of some limitation, I won't be able to change the script content.
Any help to overcome will be appreciated.

Your Groovy snippet is incorrect - Groovy does not support notation without leading zero in case of decimal numbers smaller than 1.0. If you try to compile following expression directly using groovyc:
"abcd".length() >= .34
compilation will fail with error like:
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
test.groovy: 2: Unexpected input: '.' # line 2, column 20.
"abcd".length() >= .34
^
1 error
Java supports such notation, however Groovy from 2.x up to 3.0.0-alpha-3 version does not support it.
Solid solution
Fix the input Groovy code snippet to contain only a valid and compile-ready code. Any invalid Groovy statements or expressions will lead to failures and compilation errors.
Workaround: add leading zeros with replaceAll() method
The only way to compile such incorrect snippet is to replace all .\d+ (dots followed by at least one space and ended with a number) with 0.$1. Consider following example:
def snippet = "\"abcd\".length() >= .34; \"efgh\".length() >= .22; \"xyz\".length() >= 0.11;"
println snippet.replaceAll(' \\.(\\d+)', ' 0.$1')
It adds 0 to all decimal numbers where leading zero is missing. Running this example prints following output to the console:
"abcd".length() >= 0.34; "efgh".length() >= 0.22; "xyz".length() >= 0.11;
If you pass such modified snippet to GroovyShell.evaluate() method it will run with no errors.
Of course this is not a rock-solid solution and it is just a way to automatically fix some of the syntax errors introduced in the code snippet. There are some corner cases where this workaround may cause some side effects, you have to be aware of it.

Go version is go version xgcc (Ubuntu 4.9.3-0ubuntu4) 4.9.3 linux/amd64
Running Linux Mint 17.3 Cinnamon
Anyone know what I'm doing wrong?
Looks like you are using go cgo installation. On Linux mint golang-go seems to be the distribution name.
But I would suggest installing the latest version of go (or version go 1.5 atleast) as mentioned in the below link and try again.
https://golang.org/doc/install
Remove your current installation before proceeding with the golang-go installation.
I have a problem with syntax in cobol. I'm using open-cobol package on Ubuntu 4.2.0-16-generic, and i've got error:
~/cobol$ cobc -free -x -o cal cal.cbl
cal.cbl:6: Error: syntax error, unexpected $undefined, expecting "end of file"
My cal.cbl file:
IDENTIFICATION DIVISION.
PROGRAM-ID. cal.
ENVIRONMENT DIVISION.
DATA DIVISION.
?? OPTION PIC 9 VALUE ZERO.
?? NUM1 PIC 9(5)V9(2) VALUE ZERO.
?? NUM2 PIC 9(5)V9(2) VALUE ZERO.
?? RESULT PIC 9(10)V9(2) VALUE ZERO.
PROCEDURE DIVISION.

I'm new in cobolt, i know something about columns and thats why I'm using -free flag to compile, but this error have no sense for me.
Why this error occurs, please help:)
?? is no valid COBOL word and no level number (which is needed in line 6). These messages come from OpenCOBOL/GnuCOBOL 1.1.
Newer GnuCOBOL versions are much better in many ways, including user messages (here with GC 2.2):
cal.cob: 6: Error: Invalid symbol: ? - Skipping word
cal.cob: 6: Error: PROCEDURE DIVISION header missing
cal.cob: 6: Error: syntax error, unexpected Identifier
cal.cob: 7: Error: Invalid symbol: ? - Skipping word

cal.cob: 12: Error: 'OPTION' is not defined
cal.cob: 15: Error: 'NUM1' is not defined
cal.cob: 17: Error: 'NUM2' is not defined
Change ?? to 01 or 77 and you don't have the error any more. Insert WORKING-STORAGE SECTION or LOCAL-STORAGE SECTION after DATA DIVISION and your program compiles fine.
