Compilation with GCC 8.2.0 fails #3798
Comments
Do you have a way of testing GCC 9.x or later? This may be a compiler error or missing feature in GCC 8.x and/or a problem in the libstdc++ standard library implementation. The diagnostic message means that the compiler is unable to specialise If you don't have an easy way of testing GCC 9.x, I'd like to run a little experiment if you wouldn't mind. Can you create the following three files ( g++ -std=c++17 -Wall -Wextra -pedantic -o t main.cpp k.cpp && ./tIf all goes well the command should print
to the shell. If not, do you get anything else if you replace k.hpp#include <memory>
#include <string>
class K
{
public:
K();
~K();
std::string str() const;
private:
class Impl;
std::unique_ptr<Impl> pImpl_;
};k.cpp#include "k.hpp"
class K::Impl
{
public:
std::string str() const { return "pImpl"; }
};
K::K() : pImpl_ { std::make_unique<Impl>() } {}
K::~K() = default;
std::string K::str() const { return this->pImpl_->str(); }main.cpp#include "k.hpp"
#include <iostream>
int main()
{
K k{};
std::cout << "hello, " << k.str() << '\n';

That example compiles with g++-8 (g++-8 -std=c++17 -c k.cpp -o k.o; g++-8 -std=c++17 -o main main.cpp k.o) with diff --git a/k.hpp b/k.hpp

Well, at least with g++-8.3.0-6 on Debian, which might have additional patches applied. |
Hm, weird. Did you have to |

@bska Thank you for the fast and helpful reply and for providing the code example. Next to GCC 8.2.0, I can also use GCC 9.3.0 or 11.4.0 (for those I just need to build a few missing dependencies like zoltan, but this should not take a lot of time). The example seems to build fine with all 3 compilers: GCC 8.2.0: GCC 9.3.0: GCC 11.4.0: What also confuses me a bit is, that when the compilation fails and I rerun the command that failed: /cluster/spack/apps/linux-centos7-x86_64/gcc-4.8.5/gcc-8.2.0-6xqov2fhvbmehix42slain67vprec3fs/bin/g++ -DBOOST_ALL_NO_LIB -DBOOST_SYSTEM_DYN_LINK -DFMT_HEADER_ONLY -DHAVE_CONFIG_H=1 -I/scratch/tmp.37674213.sfux/opm-common-release-2023.10-final/build -I/scratch/tmp.37674213.sfux/opm-common-release-2023.10-final/external/cjson -I/scratch/tmp.37674213.sfux/opm-common-release-2023.10-final/build/include -I/scratch/tmp.37674213.sfux/opm-common-release-2023.10-final -isystem /scratch/tmp.37674213.sfux/opm-common-release-2023.10-final/external/fmtlib/include -isystem /cluster/apps/gcc-8.2.0/boost-1.74.0-bwdibdtazuvem2m7bwkiifvh7b3xvd5y/include -pipe -Wall -Wextra -Wshadow -fopenmp -pthread -O3 -DNDEBUG -ftree-vectorize -march=core-avx2 -mavx2 -UNDEBUG -fPIC -fopenmp -std=c++17 -MD -MT MakeFiles/opmcommon.dir/src/opm/input/eclipse/Schedule/Network/Node.cpp.o -MF MakeFiles/opmcommon.dir/src/opm/input/eclipse/Schedule/Network/Node.cpp.o.d -o CMakeFiles/opmcommon.dir/src/opm/input/eclipse/Schedule/Network/Node.cpp.o -c /scratch/tmp.37674213.sfux/opm-common-release-2023.10-final/src/opm/input/eclipse/Schedule/Network/Node.cpp then this particular file Node.cpp compiles without error. Could the issue be related to CMake? Best regards Sam |
Right. To be honest, I think cmake --build . -target all --parallel 1from the top-level build directory. This will definitely take longer and it's not something we do regularly, but when debugging build problems it's often a good thing to try first. I'd very much like to know what diagnostics you get from GCC 8.2 in this instance. |

@bska Thank you for your reply. I tried running the command that you provided for serial compilation. Now the compilation fails at 50%
Please find in the attachment the complete build logs (testmake.log). Thank you for helping me with this issue. |

Have you been able to somehow resolve this? |
|
No, I have not been able to resolve the issue |
|
Mmh. But you seem to have other compilers available. Do you need to to stick to 8.* because of other dependencies? |
Hi,
I am trying to build OPM-common (2023.10) on our HPC cluster. I use the following dependencies (all built from source code):
I follow the installation instructions and created the build directory, was running
ccmake ..to change some variables (to disable the addition of-march=native, as we have different node types in the cluster). Then I was runningmake -j 8to build the software in parallel. At 40% the compilation failed with the following error:I started searching the internet for this error message and found:
https://stackoverflow.com/questions/20934195/invalid-application-of-sizeof-to-incomplete-type-created-classes
which seems to discuss a similar error. Is this a known problem? And do you have any idea on how to resolve this error?
Any help is appreciated.
Best regards
Sam
