Describe the bug

Im attempting to follow instructions for building at aws-c-s3. The common Library builds successfully, but when I attempt to use it in all of the other projects they fail with the following (or similar):

cmake -S aws-checksums -B aws-checksums/build -DCMAKE_INSTALL_PREFIX=$IPATH -DCMAKE_PREFIX_PATH=$IPATH
cmake --build aws-checksums/build --target install
CMake Error at /data/john/libs/aws-c-common/cmake/aws-c-common-config.cmake:8 (include):
  include could not find requested file:

    /data/john/libs/aws-c-common/cmake/shared/@[email protected]
Call Stack (most recent call first):
  /data/john/libs/aws-c-common/cmake/aws-c-common-config.cmake:22 (aws_load_targets)
  /data/john/libs/lib/cmake/AwsFindPackage.cmake:19 (find_package)
  CMakeLists.txt:130 (aws_use_package)

Expected Behavior

Other packages build correctly

Current Behavior

Build fails

Reproduction Steps

Follow aws-c-s3 on Ubuntu 22.04

Possible Solution

install-path must be an absolute path in the following instructions.

Are you doing this?

[johnramsden]

@graebm Yes:

IPATH=/data/john/libs

[jmklix]

Have you build aws-lc and s2n-tls?

If you are building on Linux, you will need to build aws-lc and s2n-tls first.

[johnramsden]

@jmklix Yes, built and installed per aws-c-s3 readme

[bretambrose]

Can you attach the full command line and output from building and installing aws-c-common. Also what is the full directory path you are building from?

[johnramsden]

@bretambrose Uploaded output o.txt of:

IPATH=/data/john/libs
cd /data/john/libs

git clone https://github.com/awslabs/aws-c-common.git
cmake -S aws-c-common -B aws-c-common/build -DCMAKE_INSTALL_PREFIX=$IPATH
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=$IPATH -DCMAKE_PREFIX_PATH=$IPATH
cmake --build aws-checksums/build --target install

Already ran (to success):

IPATH=/data/john/libs
cd /data/john/libs
git clone https://github.com/awslabs/aws-lc.git
cmake -S aws-lc -B aws-lc/build -DCMAKE_INSTALL_PREFIX=$IPATH
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=$IPATH -DCMAKE_PREFIX_PATH=$IPATH
cmake --build s2n-tls/build --target install

[bretambrose]

You're installing into and building from the same tree/directory. Try installing to an unrelated directory.

[johnramsden]

You mean different CMAKE_INSTALL_PREFIX each lib? Instructions say to use the same one

[johnramsden]

They are using individual build directories:

./aws-lc/build
./s2n-tls/build
./aws-c-common/build
./aws-checksums/build

[johnramsden]

Tried building in /data/john/src:

IPATH=/data/john/libs
cd /data/john/src
git clone https://github.com/awslabs/aws-lc.git
cmake -S aws-lc -B aws-lc/build -DCMAKE_INSTALL_PREFIX=$IPATH
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=$IPATH -DCMAKE_PREFIX_PATH=$IPATH
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=$IPATH
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=$IPATH -DCMAKE_PREFIX_PATH=$IPATH
cmake --build aws-checksums/build --target install

CMake Error at /data/john/libs/aws-c-common/cmake/aws-c-common-config.cmake:8 (include):

[bretambrose]

Did you completely delete the full tree (/data/john/libs)?

I just ran the same steps only with a different IPATH value and everything works as expected.

[johnramsden]

@bretambrose Thanks I tried that and it was successful. I'm not sure what the cause of the conflict was

[bretambrose]

I suspect cmake was searching a directory that contained both the repository source (which includes pre-config cmake files) and the installed cmake files (post-config) and getting really confused.
