Examples for ParserGenerator - parser-generator

Can any one post some sample code for Bumble Bee Parser Generator?
I want to create a Parser to parse some BSDl Files.
Please post some sample code to write lex and yacc using bumble bee parser generator

If you install the parser generator, you should be able to browse example source code from C:\Program Files\Parser Generator 2\Cpp\Examples

Trouble using hash function from libsodium library

I have a question related to using hash function available in the libsodium library. https://libsodium.gitbook.io/doc/hashing/generic_hashing
The problem is when I try to use it I get an error message: undefined reference to crypt_generichash()
I am also confused about the installation procedure mentioned in here:
https://libsodium.gitbook.io/doc/installation
I just download the folder and place it in my code folder so I guess maybe the error is because of the reason that I didn't follow the configuration because I couldn't understand how to do it. Do I need to go to the path and then execute the commands mentioned like (./configure) but when I do it still gives me an error. As I am a beginner so I do not know how should I do it.
I am using:
Contiki (ver 3.0)
Language C
Ubuntu (16.04)

Flite doesn't produce speech without creating a .WAV file?

I am trying to run flite TTS for a project, and I encountering an issue where there's no output sound when I run this command.
flite -t hello
But, when I run this command, it creates a .wav file and I can play it.
flite -t hello -o hello.wav
I managed to compile with the correct libraries and downloaded the required voice files {source code} so there are no issues there, and after looking in Stackoverflow I found a few questions posted about this{link}, but none of them works with mine. Also, I tried running the sample C code given in the flite's documentation {doc}, but that doesn't produce any output speech either.
//extracted from the sample code
flite_file_to_speech(argv[1],v,"play");
Could anyone suggest me a way to generate the speech with flite, without creating a .wav file?

how to install mcrypt and add mcrypt.h to my C program files?

I need to work on trying to get AES encryption/decryption on some examples and have to use mcrypt.h in my C files. However, I do not know how to install them. I have downloaded and unzipped mcrypt-2.6.7-win32 which from https://sourceforge.net/projects/mcrypt/
I can't seem to figure out how to continue and "install" this header. Please advice.
You just need add those files to your project, add #include mcrypt.h to source which uses mcrypt, and add mcrypt.a to be linked together with your code.

Compile and link two files using cmake?

I have two files in my project.
One is a ".c" file, one is a ".asm" file. First, I compile both the files into two ".o" object files and then link together using a custom linker script.
Currently, I am using a simple bash script with manual commands to build the project, but as the project size is expected to increase, I was thinking of moving the project to using cmake as its primary build system.
I have searched documentation of cmake and googled for a lot of time, although I have shortlisted some of the variables in cmake which might prove to be useful in this case, I am unable to find any sample explaining how to achieve this.
Can anybody provide me with a brief sample code on how should I go about achieving this ?
You asked for an example? Here's one from the cmake wiki
set(mySrcs foo.c bar.c)
set(can_use_assembler FALSE)
# test wether it is a x86 machine and as/gas is available
if("${CMAKE_SYSTEM_PROCESSOR}" MATCHES "i.86")
enable_language(ASM-ATT)
if(CMAKE_ASM-ATT_COMPILER_WORKS)
set(can_use_assembler TRUE)
set(mySrcs ${mySrcs} codec_i86.s)
endif(CMAKE_ASM-ATT_COMPILER_WORKS)
endif("${CMAKE_SYSTEM_PROCESSOR}" MATCHES "i.86")
# no assembler found
if(not can_use_assembler)
set(mySrcs ${mySrcs} codec_generic.c)
endif(not can_use_assembler)
add_executable(player ${mySrcs})
Because of the way that CMake works, assembling and linking are grouped together in the same step (from the programmer's perspective at least). So add_executable automatically handles everything for you.
If you want to include a linker script, that gets more difficult with CMake. The best place to look into it is over here. Since the examples and instructions are too long to copy out in the SO answer box, I'll leave the reading to you.

Regarding linking CLI Parser to my application

I am using an open source CLI parser (this one -> http://sourceforge.net/projects/cliparser/) to add command line interface to my application and it works really neat on its own, but I am having trouble adding it to my application. The documentation provided is very meager and I have limited experience with makefiles. If anyone has used this parser before could you help me out with it?
Specifically, how do I make the parser run within my program? The document says"link your parser against libparser.a" What does that mean?
Thanks!
When you compile your program, you need to link against the library. If using GCC, this is done via two ways:
You can specify the path to the library:
gcc myapp.c /somepath/libparser.a
Or, if it is in your standard library directory you should be able to do:
gcc myapp.c -l parser
