[Linux] RockyLinux 9 编译安装 davfs2

官网：davfs2 - Summary [Savannah] (nongnu.org)
下载地址：Index of /releases/davfs2/ (nongnu.org)
下载最新版

wget https://download.savannah.nongnu.org/releases/davfs2/davfs2-1.7.0.tar.gz
tar zxvf davfs2-1.7.0.tar.gz
cd davfs2-1.7.0
mkdir build && cd build

CFLAGS="-fPIE" LDFLAGS="-fPIE" CPPFLAGS="-fPIE" ../configure

make -j8
make install

直接 ../configure 构建的时候会出现问题

/usr/bin/ld: cache.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: dav_fuse.o: relocation R_X86_64_32 against `.rodata' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: kernel_interface.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: mount_davfs.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE
/usr/bin/ld: webdav.o: relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a PIE object; recompile with -fPIE

大概意思就是编译的文件和库文件使用了不匹配的pie选项，导致连接失败，所以需要指定-fPIE
这个选项是通过../configure --help得到的

如果你是其他项目出现了这个问题，也可以试着添加-no-pie选项，总之用到的库和可执行程序的pie选项要统一
