static linking fails
envgap__PurpleI2P__i2pd-612
01 / FAILURE SIGNATURE
As reported upstream
It fails with errors of the type `undefined reference to `dlopen'`. I found a simple fix: to move `-ldl` option in the building command line to the very end. But I have no idea how to fix this properly.
Not a benchmark task.
- In a clean container the reported failure did not reproduce, or the known fix did not make the project run.

PurpleI2P/i2pd #612 · read the original issue
Hi, following gentoo bug [591334](https://bugs.gentoo.org/show_bug.cgi?id=591334), I am trying to build i2pd with
```
cmake -DCMAKE_BUILD_TYPE=Release -DWITH_STATIC=ON
make
```
It fails with errors of the type `undefined reference to `dlopen'`. I found a simple fix: to move `-ldl` option in the building command line to the very end. But I have no idea how to fix this properly.
I would be happy to provide any details. Build log:
