cmake error

[Helena2007]

I have installed Adaptive Cpp. when trying to run the examples project, in the examples/build folder got the following error, when running the cmake command,

cmake .. -DAdaptiveCpp_DIR=/...../AdaptiveCpp/build -DACPP_TARGETS= 'cuda:sm_86'
CMake Warning:

I have noticed that in usr/local/lib/cmake folder named AdaptiveCpp has not been generated. However there were no errors when building and installing AdaptiveCpp.

Could you share a reproducer for your installation of AdaptiveCpp?

[illuhad]

Have you actually run make install ? Just running make is insufficient.

The AdaptiveCpp_DIR variable must point to INSTALL_ROOT/lib/cmake/AdaptiveCpp (Replace INSTALL_ROOT with your CMAKE_INSTALL_PREFIX).

Ignoring extra path from command line:

"cuda:sm_86"

Regarding this: This is probably due to the space after -DACPP_TARGETS=

[Helena2007]

Thank you, @illuhad @nilsfriess following your suggestions I was able to successfully run the cmake command without any errors.
But got error when running make install

[nilsfriess]

Can you make sure that the libstdc++ version that you use to build AdaptiveCpp itself and the example match as suggested here:
#1428 (comment) ?

[Helena2007]

when run the command,
ldd AdaptiveCpp/build/src/runtime/libacpp-rt.so | grep libstdc++
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007edcf2800000)

AdaptiveCpp uses libstdc++.so.6

[nilsfriess]

Now we have to find out if that's the same as clang is trying to use when you compile your example. Not sure how to best do this, maybe just compile a simple Hello World program using the clang that acpp is using (you can get that from cat /your/AdaptiveCpp/install/directory/etc/AdaptiveCpp/acpp-core.json | grep \"default-clang\") and then again do ldd helloword | grep libstdc++

[Helena2007]

when run cat /.../AdaptiveCpp/etc/AdaptiveCpp/acpp-core.json | grep "default-clang" got the output
"default-clang" : "/usr/lib/llvm-14/bin/clang++",

when run the command ldd helloworld | grep libstdc++
libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007383f3000000)

[nilsfriess]

Not sure what the problem is then.

Have you tried just manually compiling the example using acpp? Maybe something is going wrong with the CMake config for the example. So in the examples/bruteforce_nbody folder run something like

ACPP_INSTALL_DIR/bin/acpp -o bruteforce_nbody bruteforce_nbody.cpp -v

and post the output here.

[Helena2007]

When run the command /....../AdaptiveCpp/bin/acpp -o bruteforce_nbody bruteforce_nbody.cpp -v got the output:

acpp warning: No optimization flag was given, optimizations are disabled by default. Performance may be degraded. Compile with e.g. -O2/-O3 to enable optimizations.

[nilsfriess]

And does the compilation succeed? Or is there still the same error as before?
If it succeeds this way, then there is probably something wrong with your installation or the way you configured the example/ the project itself. I‘d suggest you then just start over with a clean build directory and if the error persists, post the complete output here so that we can try to reproduce the problem.

[Helena2007]

Upon compilation, there were no errors. After the compilation, an executable bruteforce_nbody was created. When this executable was run a txt file named output.txt was created. The txt file contains x, y, z coordinates and a scalar value.
Tried the entire steps with a clean build directory and still the error persists.
In AdaptiveCpp/examples/build folder run the following commands:
cmake .. -DAdaptiveCpp_DIR=/.../AdaptiveCpp/lib/cmake/AdaptiveCpp -DACPP_TARGETS='cuda:sm_86'

Okay, this means that acpp compilation and linking works and the program runs correctly.

For building with cmake, can you please:

• remove CMakeCache.txt in your build directory of the example code
• rerun cmake as in the command you posted
• compile with make VERBOSE=1 and post the output of that command.
