Hello i have cloned the repo in "boost/lib/numeric" in ublas folder as advised but when i am running the build command of b2 driver program for Boost.Build engine i am getting the following error what can be a solution to it.

@amitsingh19975

@Neel-Shah-29, did you read the message clearly? it's asking for a toolset (GCC, clang, or any other), which it is unable to find.

Neel-Shah-29

@Neel-Shah-29

yes i have installed g++ , clang++ 10,clang++ 11 before running that command

maybe you are missing b2 config file or maybe you skipped it. If you have it, then read the b2 reference on how to provide a toolset.

Check if ~/user-config.jam exists or not. If not use the following command on the terminal.

echo "using gcc: : g++ ;" >> ~/user-config.jam;

Neel-Shah-29

@Neel-Shah-29

yes it was not existing so i ran the above command in terminal

now if i run ~/user-config.jam it shows permission denied.

amitsingh19975

@amitsingh19975

I think I told you that your home directory requires root permission.

This is common Linux knowledge.

Neel-Shah-29

@Neel-Shah-29

yes yes i gave the root permission

This is my user-config.jam.

using clang : : clang++ : <cxxflags>"-std=c++20" <linkflags>"" <link>"-lboost_unit_test_framework" ;

I think you need to check your binary see the name of the GCC binary there, and then put it in here, or check the b2 document on how to set gcc toolset.

Neel-Shah-29

@Neel-Shah-29

This is my user-config.jam should i replace the content here to what you sent?

amitsingh19975

@amitsingh19975

what's the version of your gcc?

Neel-Shah-29

@Neel-Shah-29

gcc --version
gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0

amitsingh19975

@amitsingh19975

find the GCC binary name in the Linux binary folder, and try to replace it, something like this gcc-9: : g++-9.

check if it works.

also add <cxxflags>"-std=c++20" <linkflags>"" <link>"-lboost_unit_test_framework".

i need to replace gcc in bin folder by gcc-9: : g++-9 right?

amitsingh19975

@amitsingh19975

gcc also should work, but anyway, try it. Paste the following command as it is, and check again. Maybe you added some non-printable characters.

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

if the command does not work, add the gcc version next to it as specified above.

there is a space before and after :. Therefore, be careful while pasting.

Neel-Shah-29

@Neel-Shah-29

This is my user-config.jam. is it ok?

amitsingh19975

@amitsingh19975

Keep single toolset, and add double quotes as written in my command.
