# FAQ
|
|
|
|
## Registry not found
|
|
|
|
```
|
|
error: registry not found
|
|
```
|
|
|
|
**Solution:** Make sure `~/.dcr/config.toml` exists:
|
|
|
|
```toml
|
|
[[registry]]
|
|
name = "default"
|
|
url = "https://index.dcr.pm"
|
|
```
|
|
|
|
And check `DCR_INDEX_PATH`:
|
|
|
|
```bash
|
|
echo $DCR_INDEX_PATH
|
|
```
|
|
|
|
## Compiler not found
|
|
|
|
```
|
|
error: compiler not found
|
|
```
|
|
|
|
**Solution:** Ensure a compiler is installed and available in PATH.
|
|
|
|
```bash
|
|
which gcc
|
|
which clang
|
|
```
|
|
|
|
Or specify explicitly via `[toolchain]` in `dcr.toml`.

## openssl-sys build failed
|
|
|
|
When building DCR from source:
|
|
|
|
```
|
|
error: failed to run custom build command for openssl-sys
|
|
```
|
|
|
|
**Solution:** Install OpenSSL development headers:
|
|
|
|
```bash
|
|
# Ubuntu/Debian
|
|
sudo apt install libssl-dev
|
|
|
|
# Fedora
|
|
sudo dnf install openssl-devel
|
|
|
|
# macOS
|
|
brew install openssl
|
|
```
|
|
|
|
## Ctrl+C during build
|
|
|
|
DCR handles SIGINT: interrupts the current compilation and exits with non-zero code.

## Lock file
|
|
|
|
`dcr.lock` is created during builds (`dcr build`) when registry dependencies are present. To force an update — delete `dcr.lock` and run `dcr build`.
