I'm working on an old erlang code that uses Makefiles to compile.
The makefile defines some "include" paths:
# Erlang include directories.
HRL_INCLUDE_DIRS = \
../include
My module imports modules from that path and uses it:
-include("logger.hrl").
VS Code doesn't seem to find this file (red squiggly line under the include statement and function calls.), because logger should have relative or absolute path.
The Makefile does the magic behind the scenes but VS Code doesn't read it.
How to configure VS Code to read the makefile?
The question is where the red squiggly line is coming from. Are you using the erlang-ls extension? If so, you probably need to configure include_dirs in an erlang_ls.config file in the root of your project.
include_dirs:
- "path/to/include"

I've downloaded the binaries: or-tools_VisualStudio2022-64bit_v9.3.10497
I'm using vs2022 on win10. My shell has cygwin in the path if it's related.
I ran
%comspec% /k "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat"
cl.exe is in the path, and which.exe finds it.
I ran make test_cc, but it complained
the cl command was not found in your PATH
exit 127
make: *** [Makefile:271: test_cc] Error 127
The var CXX_BIN was empty even though which cl returned the correct path. I set it manually to cl.
Then, there was a complaint about echo and a newline, which I commented out. Then, it couldn't find md, so I created manually md objs.
A few of the examples were built, but then it stopped with another error. For now, I just got what I want:
make run SOURCE=examples/cpp/solve.cc
but probably there was an easier way to get it?
I tried to build it from the source using cmake. Doesn't work off-the-shelf as well:

cmake looks more promising, and I was missing dependencies. Should give it a flag -DBUILD_DEPS:BOOL=ON.
OR-Tools depends on few external dependencies so CMake build will try to find them using the idiomatic find_package() => your distro/env(vcpkg ?) must provide them, just regular CMake stuff here.
ref: https://cmake.org/cmake/help/latest/command/find_package.html
note: we provide few findFoo.cmake here https://github.com/google/or-tools/tree/main/cmake
We also provide a meta option to build statically all our dependencies, simply pass -DBUILD_DEPS=ON cmake option at configure time.
You can also build only some of them, please take a look at
https://github.com/google/or-tools/tree/main/cmake#dependencies
Concerning Gurobi and GRBtunemodeladv symbol, this one has been removed by last version of Gurobi so we fix it in v9.4/main/stable branch...

I am building a flutter plugin which calls native functions from lib.dll file and everything works as expected in my computer.
But I use relative path to link that lib such as
E:/_Projects/mahesabu/client/packages/server/windows/lib.dll
Now I want to move the build process in CI/CD which I believe using relative path such as
./lib.dll would be very easy.
Of cource I am new to cmake configuration. And in one comment it is written
List of absolute paths to libraries that should be bundled with the plugin
I wonder how can I use relative path there, because if I try build fails. The following is CMakeLists.txt
cmake_minimum_required(VERSION 3.14)
set(PROJECT_NAME "server")
project(${PROJECT_NAME} LANGUAGES CXX)
# This value is used when generating builds using this plugin, so it must
# not be changed
set(PLUGIN_NAME "server_plugin")
add_library(${PLUGIN_NAME} SHARED
"server_plugin.cpp"
)
apply_standard_settings(${PLUGIN_NAME})
set_target_properties(${PLUGIN_NAME} PROPERTIES
CXX_VISIBILITY_PRESET hidden)
target_compile_definitions(${PLUGIN_NAME} PRIVATE FLUTTER_PLUGIN_IMPL)
target_include_directories(${PLUGIN_NAME} INTERFACE
"${CMAKE_CURRENT_SOURCE_DIR}/include")
target_link_libraries(${PLUGIN_NAME} PRIVATE flutter flutter_wrapper_plugin)
# List of absolute paths to libraries that should be bundled with the plugin
set(server_bundled_libraries
""
"E:/_Projects/mahesabu/client/packages/server/windows/lib.dll" #USE RELATIVE PATH HERE
PARENT_SCOPE
)
Any help will be appreciated.
Just use:
set(server_bundled_libraries "${CMAKE_CURRENT_SOURCE_DIR}/lib.dll" PARENT_SCOPE)
The CMAKE_CURRENT_SOURCE_DIR variable will expand to current source directory as tracked by add_subdirectory. This is usually, but not always, the directory in which the present CMakeLists.txt resides. Presumably, this is E:/_Projects/mahesabu/client/packages/server/windows on your computer (given your remark that you expect ./lib.dll to work), but will be somewhere else on CI or elsewhere.
While compiling Swift on Mac machine, there is a dynamic library libswiftDemangle.dylib created. I need the dynamic library created on Linux machine as well, however, the dynamic library isn't created after a compilation of a source code.
The file CMakeLists.txt at lib/SwiftDemangle/CMakeLists.txt contains:
add_swift_library(swiftDemangle SHARED
SwiftDemangle.cpp
MangleHack.cpp
LINK_LIBRARIES swiftBasic)
directive, however the library isn't created.
I use this command ./swift/utils/build-script -R -c --build-subdir build --install-prefix /mnt/servers/swift/install -j4 to build the project, eventually it runs cmake and ninja to build the project.
Any ideas?
I can take a shot at explaining why the library is not getting built on Linux, even if it's late probably.
The main subdirectory containing the library you mention is:
https://github.com/apple/swift/tree/master/lib
To build the libs in that directory, which are organized in subdirectories, the following CMakeLists.txt is used:
https://github.com/apple/swift/blob/master/lib/CMakeLists.txt.
As can be clearly seen in this file, the library that you mention is only built if the system is OSX/Darwin and not in the Linux case. The relevant code in the aforementioned CMakeLists.txt is:
add_subdirectory(RemoteAST)
add_subdirectory(Sema)
add_subdirectory(Serialization)
if(CMAKE_SYSTEM_NAME STREQUAL "Darwin")
add_subdirectory(SwiftDemangle)
endif()
add_subdirectory(SIL)
add_subdirectory(SILGen)
As you can see it,
if(CMAKE_SYSTEM_NAME STREQUAL "Darwin")
add_subdirectory(SwiftDemangle)
endif()
prevents SwiftDemangle to be built on Linux.
A superficial double check can be to look at:
https://github.com/apple/swift/blob/master/lib/SwiftDemangle/CMakeLists.txt
which will install or simlynk only *.dylib files.
It it worth mentioning that the swift-demangle tool (different from what you asked)
https://github.com/apple/swift/tree/master/tools/swift-demangle
is built on Linux.
I am trying to create an eclipse project from a cmake project .
I used the following command
cmake -G "Eclipse CDT4 - Unix Makefiles" ./`
it gives the following error
CMake Error at CMakeLists.txt:119 (find_package):
By not providing "FindGlib.cmake" in CMAKE_MODULE_PATH this project has

I have glib installed . actually it couldn't resolve the path i guess. wherever find is there in cmake file , it is giving the smiler errors. please i suggest a way out, i badly need to load this project in cmake. Thanks.
Here is line 119 where error message is pointing
find_package(Glib 2.28 REQUIRED)
include_directories(${Glib_INCLUDE_DIRS})
list(APPEND LIBS ${Glib_LIBRARIES})
add_definitions(${Glib_DEFINITIONS})
When you call find_package(MyPackage) in a CMake file, it tries to find a FindMyPackage.cmake configuration in its system path (/usr/share/cmake-2.8/Modules on my Ubuntu box), or in the directory you did specify as CMAKE_MODULE_PATH).
The solution to your problem is to create a directory for modules in your source tree (e.g. CMakeModules), put in it a FindGlib.cmake file that you can find using Google, and add
set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/CMakeModules)
in your CMakeLists.txt before the actual call to find_package.
(your problem is not related to the Eclipse generator, you could remove that from the title of the question).
I have different behaviour of compiler, when building project from IDE and from command-line, which I can not explain.
The detailed issue's description is rather big, but it's really simple.
I have a C++ Builder project, which has a PAS-file included (IncludeUnits.pas). This pas-file has several units and inc-files listed. These files are located in separate folders and these folders are listed in library&include paths in project's options.
Folders layout:
C:\Demo\Bin
C:\Demo\Project
C:\Demo\Project\CBuilder5
C:\Demo\Project\Common
C:\Demo\Source
C:\Demo\Source\Common
Bin is output folder, Project/CBuilder5 holds project (bpr-file), Project/Common holds included pas-file (IncludeUnits.pas), Source and Source/Common hold other files (pas&inc). I think that it's pretty usual layout.
C:\Demo\Project\Common\ IncludeUnits.pas :
unit IncludeUnits;
interface
uses
Test;
implementation
end.
C:\Demo\Source\ Test.pas :
unit Test;
interface
{$I Test.inc}
implementation
end.
C:\Demo\Source\Common\ Test.inc :
// this file is empty
If I compile this project from C++ Builder IDE - it will compile fine. C++ Builder IDE doesn't have any additional paths in IDE settings set.
Now, I want to compile it from command-line. First, I issue
bpr2mak.exe MyProject.bpr
command.
This command creates MyProject.mak file, where I can see all paths ("....\Source" and "....\Source\Common" are the paths in question):
...
INCLUDEPATH = $(BCB)\include;$(BCB)\include\vcl;..\Common;..\..\Source;..\..\Source\Common
LIBPATH = $(BCB)\lib\obj;$(BCB)\lib;..\Common;..\..\Source;..\..\Source\Common
...
Now, I run make command:
make.exe -B -f"MyProject.mak"
It gives me the following output:
C:\PROGRA~1\Borland\CBUILD~2\BIN\dcc32 -N2....\Bin -N0....\Bin -$Y+ -$W -$R -v -JPHNE -M -UC:\PROGRA~1\Borland\CBUILD~2\bin..\include;C:\PROGRA~1\Borland\CBUILD~2\bin..\include\vcl;..\Common;..\..\Source;..\..\Source\Common -D_DEBUG;_RTLDLL;NO_STRICT -OC:\PROGRA~1\Borland\CBUILD~2\bin..\include;C:\PROGRA~1\Borland\CBUILD~2\bin..\include\vcl;..\Common;..\..\Source;..\..\Source\Common --BCB ..\Common\IncludeUnits.PAS
Borland Delphi Version 13.0 Copyright (c) 1983,99 Inprise Corporation
C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(1) C:\Demo\Project\Common\IncludeUnits.pas(6) C:\Demo\Source\Test.pas(1) C:\Demo\Source\Test.pas(5) Fatal: File not found: 'Test.inc'
As you can see - all search path is passed to compiler and the file (Test.inc) is all here - in that Source\Common folder. But still compiler can't find it?
Of course, I run both commands from folder with bpr-file. And changing paths to absolute doesn't help.
Copying Test.inc from Source\Common to Source will help. Changing {$I Test.inc} to {$I Common\Test.inc} will also help.
Why? It seems that I'm missing something. Remember: project have no problems with compiling from IDE, Test.inc is found without copying or changing declaration. Did I miss some switch to make or dcc32?
I found the reason: command line for dcc32 misses -I switch, which specifies paths for include files.
For some reason, bpr2mak doesn't respect this option. Fortunately, it allows you to specify alternate template for conversion bpr -> mak. I edited default template and added "-I" option to it, pass new template to bpr2mak - and it worked.
