I got a following problem. We have a very silly git structure and guidelines, so my eclipse projects use linked files. I have to make google tests for the projects, and the only way I found it to work is to use cmake. However, the test files are not in workspace but in a git repository and only linked to eclipse project. I cant figure out how to make CMakeLists.txt to follow the files.... I tried using include_directories with either relative or absolute paths..
Errors I get:
mingw32-make.exe[2]: *** No rule to make target 'C:/Users/name/eclipse-
workspace/MyTestCmake/Solver_test.cpp', needed by 'CMakeFiles/Solver_test.dir/Solver_test.cpp.obj'. Stop.
mingw32-make.exe[1]: *** [CMakeFiles\Makefile2:164: CMakeFiles/Solver_test.dir/all] Error 2
mingw32-make.exe: *** [Makefile:145: all] Error 2
Another question is - one of the libraries is built without cmake. How can I specify the path to it, where the cmake should find it?
Current Cmakelists.txt:
cmake_minimum_required(VERSION 3.14)
project (RadiTestCmake)
include(FetchContent)
FetchContent_Declare(googletest GIT_REPOSITORY https://github.com/google/googletest.git GIT_TAG release-1.12.1 )
# For Windows: Prevent overriding the parent project's compiler/linker settings
set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
FetchContent_MakeAvailable(googletest)
enable_testing()
include_directories(

"${PROJECT_BINARY_DIR}/../../../../../../gitlocal/backend/tests/"
)
add_executable(
hello_test
hello_test.cc
Solver_test.cpp

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:

On failure, solve.exe crashes with (unknown) names in the stack trace. Need to add debug symbols and graceful error handling.
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'm getting this Package Manager error, when switching to a different branch or cloning the project. Build fails and "Clean Build Folder" doesn't help.
Error:

which is required by binary target 'AWSConnect':
.../Library/Developer/Xcode/DerivedData/MyApp-cbgtlihuudupsqdzyjdbyvcwkilh/SourcePackages/artifacts/extract/AWSConnect

The following steps resolve the issue forcing all packages to download.
Product > Clean Build Folder
Delete DerivedData content (Preferences > Locations > Derived Data little arrow)
File > Packages > Reset Package Cache
Build
The Reset Package Cache step is the most important here. It forces all packages to download as if they where just added.
Another issue that can happen is if you have added a build configuration, make sure that you have replicated this build configuration name throughout all your in house libraries, frameworks and sub projects. If the project that uses your Library has no build configuration for the scheme you are building then it will not link and you will receive errors like:
failed extracting 'https://github.com/*.xcframework.zip' which is required by binary target 'BlahBlah': fchmod (file attributes) error: Operation not permitted
I am trying to program the Arudino Nano from Eclipse. It has the same processor as the Uno (Atmega328p). I have had this working before with the Uno, but have since gotten a new hard drive and had to reinstall/reconfigure everything. I am running Fedora 19 with Eclipse Kepler. I am getting an error in the build process that I don't even know where to start looking to solve, and Google hasn't been much help...
Here is the error:
make all
Building target: Arduino_Template.elf
Invoking: AVR C Linker
avr-gcc -Wl,-Map,Arduino_Template.map -mmcu=atmega328p -o "Arduino_Template.elf" ./Analog.o -l/usr/avr
/usr/lib/gcc/avr/4.8.2/../../../../avr/bin/ld: cannot find -l/usr/avr
collect2: error: ld returned 1 exit status
make: *** [Arduino_Template.elf] Error 1
17:29:38 Build Finished (took 124ms)
Has anyone encountered this before? Or does anyone have any suggestions?
Thanks.
The problem could be described like this:
First, the library should be specified only by its name and without the "lib" prefix and the ".a" suffix. The linker (this is where you get the error) will look for the library within the specified in the project paths and will add whatever is necessary to the file library name. So if the library you need is named mystuff it will look for a file named libmystuff.a.
In your case this is specified by the -l/usr/avr which I think could be misconfiguration or you did not copy/paste the entire error output. With the '-l' option you specify the name only, not the entire path to the file.
Second, the path should be specified, in the project configuration, where to look for the libraries, otherwise the linker will look for the library files only within your own project only. Often libraries are part of another project - so you need to adjust the project configuration accordingly.
I had similar problem and this is how I solved it ...
Go to menu Project/Properties. On left - choose "C/C++ Build". On right - choose the tab "Tool Settings". On the tree view choose "AVR C Linker" then "Libraries" sub-item. You are where you may need to make changes.
The list of "Libraries" is where you add libraries names, such as mystuff.
The Libraries Path is where you specify the paths to the libraries. This may look like this: "${workspace_loc:/mystuff/Release}"
The result of this is that the linker will look for this file: /mystuff/Release/libmystuff.a under you workspace root folder.
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):

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).
