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
asked CMake to find a package configuration file provided by "Glib", but
CMake did not find one.
Could not find a package configuration file provided by "Glib" (requested
version 2.28) with any of the following names:
GlibConfig.cmake
glib-config.cmake
Add the installation prefix of "Glib" to CMAKE_PREFIX_PATH or set
"Glib_DIR" to a directory containing one of the above files. If "Glib"

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'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:
Build abseil-cpp: OFF

If finds gurobi95.dll, but it can't find the function GRBtunemodeladv.
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 am following ROS–Unity Integration tutorial for ROS2. I coppied unity_robotics_demo and unity_robotics_demo_msgs to my src folder from here. When building unity_robotics_demo_msgs gives me an error. I did source install/setup.bash and colcon build. Error:

I'm trying to build my OwnCloud client. I'm using "Generic Build Instructions" from this link - https://doc.owncloud.org/desktop/2.5/building.html.
I'm stuck at 3 step with an error:
Could NOT find Qt5Keychain (missing: QTKEYCHAIN_LIBRARY)
I downloaded Qtkeychain and compiled it using this link - https://github.com/frankosterfeld/qtkeychain/wiki.
Everything is in my C disk. PATHS are set correctly. Can someone tell me what am missing here.
Adding PATH photo:
Adding a photo to be clear what am talking about:
How did you compile qtkeychain?
With the environment variable %QTDIR% set correctly, e.g. C:\Qt\Qt5.6.0\5.6\msvc2015, you should be able to compile qtkeychain
cmake -G "MinGW Makefiles" .
mingw32-make
and get a 32bit file named "libqt5keychain.dll.a".
You can then add the directory containing this file to your Windows path environment variable. This should work (it does for Nextcloud, at least).
On ubuntu 11.10 I installed eclipse from repositories, installed adt and cdt plugins. I am able to compile the hello-jni example using command line, but i would like to use eclipse for the task.
I followed the guide here: http://mhandroid.wordpress.com/2011/01/23/using-eclipse-for-android-cc-development/ and defined a PATH variable in eclipse preferences (window->preferences->c/c++->environment), pointing to the ndk-r7b folder. But the project won't buid. I get this error:
(Cannot run program "ndk-build"
(in directory "/home/athos/android/ndk-r7b/samples/hello-jni"):
java.io.IOException:
error=2, File o directory non esistente)
(last line should be "no such file or directory" in english)
If I specify "${PATH}/ndk-build" or "/home/athos/android/ndk-r7b/ndk-build" as the build command. i get this:
/home/lavoro/android/ndk-r7b/ndk-build
ERROR: Cannot find 'make' program. Please install Cygwin make package
/home/lavoro/android/ndk-r7b/ndk-build: 40: dirname: not found
or define the GNUMAKE variable to point to it.
If I define the GNUMAKE variable in window->preferences->c/c++->environment i get this:
ERROR: Your GNUMAKE variable is defined to an invalid name: /usr/bin/make
Please fix it to point to a valid make executable (e.g. /usr/bin/make)
Which is funny, since It suggests the exact same directory I indicated. Make is installed and present at the indicated location.
What am I missing?
It's a bit ugly, but you can always put
/fully/qualified/path/to/ndk-build
In your build command.

Hello List,
I am new to Java, Netbeans, and the IB Java API.
I downloaded the IB Java API software and I am using Netbeans to look at it.
On one of the files, Netbeans is indicating a problem with the file.
At the very top of the file, the author has placed a package declaration:
package samples.rfq;
Netbeans is using a red-dot to the left of the package declaration to tell me that it has a problem with the package declaration.
When I mouse-hover the package declaration, Netbeans tells me this:
Incorrect Package (Alt-Enter shows hints)
On my Mac-keyboard I press Alt-Enter and Netbeans just interprets that as an Enter (and then I need to undo that Enter).
I have 2 questions:
How do I work around the Alt-Enter-bug to see the hints?
What do you typically do when Netbeans indicates 'Incorrect Package' on one of your package declarations?
My comment to Josefx:
josefx,
I think maybe you gave me a good clue.
I looked at the file and I see it here in the (Linux) file system:
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$ ls -la /pt/z2/api/samples/rfq/SampleRfq.java
-rw-r--r-- 1 a a 14475 2008-08-13 15:49 /pt/z2/api/samples/rfq/SampleRfq.java
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$
a#z2:/pt/z2/api$ grep package /pt/z2/api/samples/rfq/SampleRfq.java
package samples.rfq;
a#z2:/pt/z2/api$
So obviously it is in a directory which matches its package declaration.
I tried running javac against the file from a variety of directories.
This works:
cd /pt/z2/api/
javac samples/rfq/SampleRfq.java
If I run javac from any other directory it fails.
So, I see a dependency between 3 things here:
Location of the SampleRfq.java
Syntax in the package declaration
Location of the javac command
Since I got javac to work, I'm convinced of 2 things:
SampleRfq.java is in the correct directory
Syntax in the package declaration is correct
So, it looks like my issue is with Netbeans.
Netbeans is too ... 'stupid' to know that:
SampleRfq.java is in the correct directory
Syntax in the package declaration is correct
How do I help Netbeans?
I posted a question to the Netbeans mail-list and the only answer I got was: "Fix the incorrect file name".
ok,
I got the error to evaporate.
steps:
abandon my netbeans project
rsync my code to a new directory; create new NB project; (NB will not let me use old code)
right-click-project: select properties
Add folder
Pick the parent of the directory corresponding to the package
Netbeans now "knows" that the package declaration matches the directory structure.
