ld 在它前面找不到圖書館

我正在嘗試建構一個涉及 on 的 rust 程序，diesel並且postgresql建構Fedora 31失敗，因為連結器找不到libpq. 因為它可以用 重現gcc，所以我用它gcc來縮短問題。

gcc -L /lib64 -lpq
/usr/bin/ld: cannot find -lpq

ls /lib64 | grep libpq
libpq.so.5
libpq.so.5.11

ldd /lib64/libpq.so.5

       libpcre2-8.so.0 => /usr/lib64/libpcre2-8.so.0 (0x00007f488569d000)

例如，libpthread 也位於 中lib64，可以找到：

gcc -L /lib64 -lpthread
/usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/9/../../../../lib64/crt1.o: in function `_start':

我是否遺漏了某些東西，或者通常應該立即找到它？

-lpq導致連結器查找libpq.so沒有 soname 後綴的 。要在 Fedora 上提供此功能，您應該安裝libpq-devel：

sudo dnf install libpq-devel
