Failed running examples from installation section of wiki

[Neel-Shah-29]

I am getting the following error when i tried to run the examples in installation section of wiki.

Also i have the file allocater_access.hpp in the same directory.

What is the possible solutions to this?

Note: I have build ublas and run tests successfully.

User-config.jam

using gcc : : g++ : <cxxflags>-std=c++20 <linkflags> <link>-lboost_unit_test_framework ;

Possible fixes i tried:

1. Changing the flags in user-config.jam
2. Changing the include path of allocater_access.hpp

*Fix:

using gcc : : g++ : <cxxflags>"-std=c++20" <linkflags>"-lboost_unit_test_framework" ;

To know more about the flags, go and read the Boost.Build documentation, which can be found here.

If you don't want to use the configuration file, you can command-line arguments to run the test.

PATH_TO_THE_B2_BINARY/b2 toolset=gcc cxxstd=20 variant=release optimization=speed PATH_TO_THE_TEST_OR_EXAMPLES_FOLDER

PATH_TO_THE_B2_BINARY/b2 toolset=gcc cxxstd=20 PATH_TO_THE_TEST_OR_EXAMPLES_FOLDER

PATH_TO_THE_B2_BINARY/b2 toolset=gcc cxxstd=20 variant=release PATH_TO_THE_TEST_OR_EXAMPLES_FOLDER

If you get the link issue from the boost unit test, use the linking flag.

yes i will try to use command line arguments to solve the issue. Thanks for the suggestion.

Using Command line arguments solves the problem.I am attaching the screenshots of output for future reference if needed.

The allocator_access.hpp should be the part of standard boost library if you have installed the boost from the package manager or used GitHub. It does not relate to the Boost.uBLAS, but if you are having an issue, I recommend you get a copy of the header file and paste it into the appropriate path.

ok sure will do it
