`install-c-lib` download a libduckdb.so "incompatible" with Alpine

[bicf]

Alpine (amd64) do not use glibc. Use instead musl libc, and the downloaded (linux-amd64) libduckdb.so is not compatible.

Alpine offer "native" duckDb binaries:

echo "https://dl-cdn.alpinelinux.org/alpine/edge/testing" >> /etc/apk/repositories
apk add --no-cache duckdb duckdb-dev

furthermore is not possible to set 2 different path (one for the header and one for the library) in Saturio\DuckDB\FFI\FindLibrary :

    private static function headerPath(): string
    {
        return implode(DIRECTORY_SEPARATOR, [self::path(), 'duckdb-ffi.h']);
    }

    /**
     * @throws NotSupportedException
     */
    private static function libPath(): string
    {
        $file = PlatformInfo::getPlatformInfo()['file'];

        return implode(DIRECTORY_SEPARATOR, [self::path(), $file]);
    }

    private static function path(): string
    {
        return
            self::getConfiguredDuckdbPath()
            ?? self::defaultPath();
    }

With a (optional) dedicated-to-lib-path environment variable the code can refer to the system library.

System libduckdb.so works well.

Thanks for sharing.

I'd like to have a look at this when I tackle #50. Probably I'll be able to find a solution for both issues.

In the meanwhile, did you try it using symlinks? I would say you can create a directory containing the binary and a symlink to /your/project/vendor/satur.io/duckdb/header/linux-amd64/duckdb-ffi.h and set DUCKDB_PHP_PATH.

The symlink approach seems to work: https://github.com/satur-io/duckdb-php/actions/runs/22274678747/job/64434800008?pr=58 (some tests are failing due to native alpine binary; it seems it doesn't load extensions automatically as expected).

Does symlink work for you @bicf? I think it's the cleanest way to deal with this issue, but let me know whether you actually need different paths for the header and the binary.

@dhernandez, I'll try and I let you know
