Ristretto Jemalloc linking error when running ./tesh.sh

[kianmeng]

Describe the bug

Building projects that depend on dgraph-io/ristretto/v2 (such as dgraph-io/badger/v4 in this case) fails on a standard Ubuntu installation due to a CGO linking error with the jemalloc library, even when libjemalloc-dev is installed.

To Reproduce

Steps to reproduce the behavior:

1. sudo apt install libjemalloc-dev
2. git clone https://github.com/hypermodeinc/badger.git
3. cd badger
4. ./tesh.sh
5. See error

Expected behavior

The Ristretto library should compile successfully with the standard go build command when libjemalloc-dev is installed. The CGO configuration should automatically include the required linker flags to resolve the C function symbols.

BGR-18 Ristretto Jemalloc Linking when running ./tesh.sh

I have faced the same issue, but for now to skip this part I have changed the script tags from jemalloc to badger_nojemalloc, I believe this issue is a linking error not app error

Well, it works now i have installed the jemalloc from the repo

sudo dnf remove jemalloc jemalloc-devel
sudo dnf install autoconf automake libtool make gcc git

git clone https://github.com/jemalloc/jemalloc.git
cd jemalloc
./autogen.sh --with-jemalloc-prefix=je_
make
sudo make install

and now i can cd to badger to try it out but you have to export some vars

export CGO_CFLAGS="-I/usr/local/include"
export CGO_LDFLAGS="-L/usr/local/lib -ljemalloc"
export LD_LIBRARY_PATH="/usr/local/lib"
go clean -modcache
go build -tags jemalloc ./...
