Thread: Unable to debug pcre program

Greeting to all.

In a previous post, I was struggling to generate a Cmake that could actually compile a source code example using pcre. Regardless of the success I've had accomplishing this, the -g flag does not add apparently debug symbols. Here's is an example of my Cmake

Code:

cmake_minimum_required(VERSION 2.8.9)
project(directory_test)

#Include directories.h
#include_directories(include)

# Add sources
file(GLOB SOURCES "src/*.c")

# Creates an executable
add_executable(main ${SOURCES})

# Add external library
target_link_libraries(main -lpcre)

# Add compilation flags
target_compile_options(main PUBLIC -Wall -g -o pcredemo.c)

Any hint or help would be very appreciated.

I don't use CMake but I am extremely skeptical about that last line, unless you are deliberately trying to make your executable file called "pcredemo.c" which seems ... odd. Does your pcredemo.c file still look like source code? What's the actual makefile that was generated?

To the extent there is a common theme in your posts, though, it seems to be that you are missing the point of this line:

Code:

file(GLOB SOURCES "src/*.c")

which is designed to add all your *.c files into your project. Consequently, any time a .c file appears in your CMake file, it is an error (because all your .c files should be accounted for here). It feels like you're adding the .c file you want to be compiled at the end of some random lines where they don't really belong, instead of putting your .c files in the src/ directory ("src" stands for "source", so all your code should be there).

You were right, I was making an amateur mistake, thanks for the help
