Arch系统下FLINT/C库安装报错：ld提示-r与-pie无法同时使用

I’ve run into this exact issue before with older C libraries on Arch—here’s what’s going on and how to fix it quickly:

Arch Linux sets GCC to enable position-independent executables (PIE) by default for security reasons, but FLINT 2.4.5 is an older release whose build system doesn’t account for this. The linker error happens because FLINT uses the -r flag (to create relocatable object files) which conflicts with the default -pie linker flag.

Here are two reliable fixes:

1. Quick Temporary Fix: Override Flags When Running Make #

Just pass the PIE-disabling flags directly to make—this avoids editing any source files:

make CFLAGS="-fno-pie" LDFLAGS="-no-pie" && sudo make install

You’ll need sudo for make install since it installs files to system-wide directories like /usr/local/lib and /usr/local/include.

2. Permanent Fix: Edit FLINT’s Root Makefile #

If you plan to recompile FLINT later or want the flags baked into the build:

• Open the Makefile in your flint-2.4.5 directory
• Find the lines defining CFLAGS and LDFLAGS
• Add -fno-pie to the CFLAGS line, and -no-pie to the LDFLAGS line. For example:

  CFLAGS = -O2 -fno-pie -Wall ... (keep existing flags)
  LDFLAGS = -no-pie ... (keep existing flags)
  

• Save the file, then run make && sudo make install as normal.

Once you’ve completed either fix, test the installation by compiling a small program that links against FLINT to confirm everything works as expected.
