Failed to build dependencies on ubuntu 20

[dbickson]

Describe the issue

The go requirement is not documented, I was able to solve it via installed 1.20.5 go from source (the default go with ubuntu 20.04 is 1.14 I think and then I got an error of missing includes).

 wget https://go.dev/dl/go1.20.5.linux-amd64.tar.gz
  sudo tar -C /usr/local -xzf go1.20.5.linux-amd64.tar.gz
  mkdir ~/.go
  GOROOT=/usr/local/go
  GOPATH=~/.go
  PATH=$PATH:$GOROOT/bin:$GOPATH/bin
  sudo update-alternatives --install "/usr/bin/go" "go" "/usr/local/go/bin/go" 0
  sudo update-alternatives --set go /usr/local/go/bin/go

After solving the go issue I am getting another error:

ubuntu@ip-172-31-30-217:/mnt/data/crtsdk$ cmake -S aws-checksums -B aws-checksums/build -DCMAKE_INSTALL_PREFIX=`pwd`

Please advise what is the correct way to compile? the first 3 projects do compile but the 4th one and later are missing those includes.

I fixed the previous error:

cmake -S aws-checksums -B aws-checksums/build -DCMAKE_PREFIX_PATH=`pwd` -DCMAKE_INSTALL_PREFIX=`pwd`

namely the -DCMAKE_PREFIX_PATH was missing. Now I got a new erorr:

@dbickson, thank you for creating the issue. Could you please try updating the path to something other than pwd, such as <pwd>/build? I've tested this and it works fine. Maybe CMake is encountering some conflicts when pwd is specified.

Regarding the GO requirement, we can disable it during the build process of Aws-lc using cmake -S aws-lc -B aws-lc/build -DCMAKE_INSTALL_PREFIX=<install-path> -DDISABLE_GO=ON. I'll update our ReadMe with this flag.

[dbickson]

HI @waahm7 I tried also routing the install prefix to another folder not pwd and it did not work either, which OS are you using? I was using Ubuntu 20.04, are you using Amazon Linux?

[waahm7]

@dbickson, I tried it on Ubuntu 20.04 using the following steps:

git clone https://github.com/awslabs/aws-lc.git
cmake -S aws-lc -B aws-lc/build -DCMAKE_INSTALL_PREFIX=/home/ubuntu/work/build -DDISABLE_GO=ON
cmake --build aws-lc/build --target install

git clone https://github.com/aws/s2n-tls.git
cmake -S s2n-tls -B s2n-tls/build -DCMAKE_INSTALL_PREFIX=/home/ubuntu/work/build -DCMAKE_PREFIX_PATH=/home/ubuntu/work/build
cmake --build s2n-tls/build --target install

git clone https://github.com/awslabs/aws-c-common.git
cmake -S aws-c-common -B aws-c-common/build -DCMAKE_INSTALL_PREFIX=/home/ubuntu/work/build
cmake --build aws-c-common/build --target install

git clone https://github.com/awslabs/aws-checksums.git
cmake -S aws-checksums -B aws-checksums/build -DCMAKE_INSTALL_PREFIX=/home/ubuntu/work/build -DCMAKE_PREFIX_PATH=/home/ubuntu/work/build
cmake --build aws-checksums/build --target install

Please let me know if I'm doing anything differently. Also, could you please try it again by deleting the previous build folder?

[dbickson]

HI @waahm7 the new instructions work on a fresh folder, many thanks!
