I am attempting to remove certain directories from my lcov tracefile, but am not having any success. I am attempting to use relative paths, and I am using cygwin. My test framework is cpputest.

Ultimately I just want to produce coverage data of this foo.c file, and I would like to exclude or remove everything else.
I have tried using absolute paths to these directories, like 'cygdrive/C/Work/git/foo_library/test/bar/*', I have also tried
'`pwd`/test/bar/*'
I am also not really sure which paths I should be specifying, the paths to the gcda files, or the path to the source files. I've tried both.
I've also tried using -b ., and -b ../ in my capture and remove commands.
Edit:
I have to run this from the test subdirectory for the paths to work out. The following shows the full paths

Edit:
If I do this: $ lcov -r lcov.info '*bar*' '*baz*' '*cpp' -o lcov-filtered.info
it does what I want. However that seems a little heavy handed.
I had the same problem as you excluding folders.
You should remove source code that you don't want to show in the result and add up to the total number of lines in the coverage ratio.
This way of relative paths works for me to exclude paths.
Set the following variable.
testBarSrcPath=pwd/test/bar/*
And then use the variable when you exclude content.
lcov -r lcov.info "$testBarSrcPath" -o lcov-filtered.info

C3 and C4 is similar to C2, just AUX_SOURCE_DIRECTORY and ADD_LIBRARY.
Well, I have a stupid looking solution to this problem, which is to add all the .c files to the SRC_LIST:
# in C2
FILE(GLOB_RECURSE SRC_LIST ./*.c)
This seems unusual because when I build with MAKEFILE it doesn't produce so many .o files.
I would like to implement a library that is based on the gobject type system. So every object is a instance of GObjectClass
In the header gwl-registry.h I have:
#define GWL_TYPE_REGISTRY gwl_registry_get_type()
G_DECLARE_DERIVABLE_TYPE(GwlRegistry, gwl_registry, GWL, REGISTRY, GObject)
Which declares the type and the function that obtains a type. This is what I should do according the gobject tutorial: https://developer.gnome.org/gobject/stable/howto-gobject.html If I understand it correctly these macro's should expand to include the instance cast GWL_REGISTRY() and type check macro GWL_IS_REGISTRY(). However both functions rely on the function gwl_registry_get_type().
If I'm not mistaken this should be implemented in the source file gwl-registry.c. Here I define the type using this code:
G_DEFINE_TYPE_WITH_PRIVATE(GwlRegistry, gwl_registry, G_TYPE_OBJECT)
Than this macro should expand to create the GType gwl_registry_get_type().
Using meson I create a library which currently looks like this:
├── data
│ └── xdg-shell.xml
├── include
│ ├── gwl-display.h
│ ├── gwl.h

└── test
├── display-test.c
├── gwayland-test.c
├── meson.build
├── registry-test.c
└── tests.h
The toplevel meson.build looks like:
project(
'GWayland', 'c',
version : '0.1',
default_options : ['warning_level=3']
)
glib_dep = dependency('glib-2.0')
gobject_dep = dependency('gobject-2.0')
wayland_dep = dependency('wayland-client')
# These arguments are only used to build the shared library
# not the executables that use the library.
lib_args = ['-DBUILDING_GWL']
subdir('src')
subdir('include')
# Make this library usable as a Meson subproject.
gwayland_dep = declare_dependency(
include_directories: include_directories('./include'),
dependencies: [glib_dep, gobject_dep, wayland_dep],
link_with : gwayland_shared_lib
)
subdir('test')
pkg_mod = import('pkgconfig')
pkg_mod.generate(
name : 'GWayland',
filebase : 'gwayland',
description : 'Meson sample project.',
subdirs : 'gwayland',
libraries : gwayland_shared_lib,
version : '0.1',
)
The src meson.build looks like:
gwayland_srcs = [
'gwl-display.c',
'gwl-registry.c',
]
gwayland_shared_lib = shared_library(
'gwayland',
gwayland_srcs,
install : true,
c_args : lib_args,
gnu_symbol_visibility : 'hidden',
include_directories : '../include',
dependencies : [glib_dep, gobject_dep, wayland_dep],
)
and the test:
test_sources = [
'gwayland-test.c',
'tests.h',
'display-test.c',
'registry-test.c',
]
test_deps = [glib_dep, wayland_dep]
test_exe = executable(
'gwayland_test',
test_sources,
dependencies: gwayland_dep,
# link_with : gwayland_shared_lib
env : [
'G_TEST_SRCDIR=#0#'.format(meson.current_source_dir()),
'G_TEST_BUILDDIR=#0#'.format(meson.current_source_dir())
]
)
test('gwayland', test_exe)
Currently in the tests I'm calling the casting macro GWL_IS_REGISTRY()
g_assert_true(GWL_IS_REGISTRY(registry));
This leads to the following error:
cc -o test/gwayland_test test/gwayland_test.p/gwayland-test.c.o test/gwayland_test.p/display-test.c.o test/gwayland_test.p/registry-test.c.o -Wl,--as-needed -Wl,--no-undefined -Wl,--start-group src/libgwayland.so /usr/lib/x86_64-linux-gnu/libglib-2.0.so /usr/lib/x86_64-linux-gnu/libgobject-2.0.so /usr/lib/x86_64-linux-gnu/libwayland-client.so -Wl,--end-group '-Wl,-rpath,$ORIGIN/../src' -Wl,-rpath-link,/home/duijn119/github/gwayland/build/src

/home/duijn119/github/gwayland/build/../include/gwl-registry.h:30: undefined reference to `gwl_registry_get_type'
collect2: error: ld returned 1 exit status
If I check the library with nm:
nm src/libgwayland.so | egrep 'get_type|new.'
000000000000193f t gwl_display_get_type
0000000000001fcd T gwl_display_new_address
000000000000231f t gwl_registry_get_type
it seems that somehow the gwl_registry_get_type is not exported for use outside of the library, itside the library/compilation unit I can call the function just fine.
Would any one please help me with glib/gobject to tell me what I'm doing wrong, or do I have some issues with meson to build the library and the tests.
You’ve explicitly asked for symbols to not be exported from your library by default:
gnu_symbol_visibility : 'hidden'
Either change that default, or explicitly mark the symbols you want to be exported by using G_MODULE_EXPORT.
You can explicitly mark the gwl_display_get_type() symbol to be exported using
#define GWL_TYPE_REGISTRY gwl_registry_get_type()
G_MODULE_EXPORT
G_DECLARE_DERIVABLE_TYPE(GwlRegistry, gwl_registry, GWL, REGISTRY, GObject)
as the get_type() function is guaranteed to be the first thing emitted by the G_DECLARE_DERIVABLE_TYPE macro.
Currently I have the following project structure, where the libs directory purpose is to store external C libraries that I download from github because they are not available on my OS's repos:
├── cli
│ └── cli.c
├── libs
│ ├── meson.build
│ └── pqueue
│ ├── pqueue.c
│ └── pqueue.h
├── modules
│ ├── algorithms
│ │ ├── a_star.c
│ │ └── a_star.h
│ ├── meson.build
├── meson.build
Where libs/meson.build is:
libpqueue_sources = [
'pqueue/pqueue.c',
]
pqueue_lib = shared_library('pqueue', libpqueue_sources)
pqueue_dep = declare_dependency(link_with: pqueue_lib)
modules/meson.build is:
algs_sources = [
'algorithms/a_star.c',
]
algs_lib = static_library('algorithms',
sources: algs_sources,
include_directories: libs_include_dirs,
dependencies: pqueue_dep)
and meson.build is:
project('graph-search', 'c')
graph_search_include_dirs = include_directories('modules')
libs_include_dirs = include_directories('libs')
subdir('libs')
subdir('modules')
cli_sources = [
'cli/cli.c'
]
executable('cli',
sources: cli_sources,
include_directories : graph_search_include_dirs,
link_with: [algs_lib])
My problem arises when I try to make an #include "pqueue/pqueue.h" inside a_star.h, it says /modules/algorithms/a_star.h:5:10: fatal error: pqueue/pqueue.h: No such file or directory, but when I move the include to a_star.c the error disappears. Sadly I need to include it on the header file because I need to export a struct that uses a type of pqueue.h
Is there a way to include pqueue.h inside a_star.h without using paths like ../../libs/pqueue/pqueue.h?
Because you don't specify libs_include_dirs for cli.c to build, compiler don't know how to search pqueue/pqueue.h.
Change your meson.build to include libs_include_dirs.
diff --git a/meson.build b/meson.build

Given a directory dir:
dir
├── sub1
│ ├── file1
│ └── file2
├── sub2
│ ├── file1
│ └── file2
└── sub3
├── file1
└── file2
fileTree('dir').each { println it } gives me this:
dir/sub1/file1
dir/sub1/file2
dir/sub2/file1
dir/sub2/file2
dir/sub3/file1
dir/sub3/file2
Instead of all the file, I just want all the directories and subdirectories:
dir/
dir/sub1/
dir/sub2/
dir/sub3/
How do I do that? I've looked at DirectoryTree, but it does not extend FileCollection (unlike FileTree), so it's not very useful.
What about this :
file('dir').eachFileRecurse(FileType.DIRECTORIES) { println it }
Gives :
dir/sub1/
dir/sub2/
dir/sub3/
You could also do
FileTree dirs = fileTree('dir').matching {
include { FileTreeElement el -> el.directory }
}
doStuff(dirs)

I installed YCM and syntastic for VIM, normally they work fine, but I have problem when it detect some errors in my code, it shows that can NOT find some head files(which is my project head file).
My directory tree shows below:
TOP
├── debug

└── root

I copied a .ycm_extra_conf.py to the TOP, meanwhile, I will generated tag and cscope file at TOP as well, therefore each time I open file on TOP, like:
howchen#host:~/Work/c/sample/src
-> gvim ./driver/driver.c
to make sure each time I can add tag and cscope file in VIM. The problem is, if I open driver.c, which contain head files： driver.h, driver_ddi.h, debug.h, common.h, code like below:
#include <stdio.h>
#include <stdlib.h>
#include "math.h"
#include "common.h"
#include "debug.h"
#include "driver_ddi.h"
#include "driver.h"
the syntastic or YCM always show it can NOT find common.h and debug.h, other head files are OK.
My YCM and syntastic config part in vimrc file:
" YCM

My .ycm_extra_conf.py write flags variable as:

# ...and the same thing goes for the magic -x option which specifies the

any wrong flags I set?
