[PATCH 1/3] BaseTools/Conf/tools_def: Fix linking using CLANGDWARF_IA32

Patrick Rudolph #101340 The clang toolchain might default to fPIE/fPIC, which prevents lld from linking the objects into a binary. Specify -fno-pie -fno-pic as done on GCC to fix linking. Test: Building the Universal Payload using the command 'python UefiPayloadPkg/UniversalPayloadBuild.py -a IA32' actually works.

Marvin Häuser #101358 Which error precisely? X64 PIE must not be disabled, as it’s used to enforce RIP-relative addressing where possible and has been for many years. Meanwhile the issues with IA32 is PIE was disabled by default for most toolchains, but some enable it nowadays (and thus it must be disabled explicitly).

I just applied Patrick's changes on top of my CLANGDWARF patches and OvmfPkgIa32.dsc builds fine. -- Rebecca Cran toggle quoted message Show quoted text On 3/17/23 2:35 PM, Rebecca Cran wrote: Building with "build -p OvmfPkg/OvmfPkgX64.dsc -a X64 -t CLANGDWARF -b RELEASE" on FreeBSD causes the following errors: ld.lld: error: relocation R_X86_64_64 cannot be used against local symbol; recompile with -fPIC defined in /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib(ExceptionHandlerAsm.obj) referenced by /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/X64/ExceptionHandlerAsm.iii ExceptionHandlerAsm.obj:(.text+0x5) in archive /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib ld.lld: error: relocation R_X86_64_64 cannot be used against local symbol; recompile with -fPIC defined in /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib(ExceptionHandlerAsm.obj) referenced by /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/X64/ExceptionHandlerAsm.iii ExceptionHandlerAsm.obj:(.text+0x14) in archive /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib ld.lld: error: relocation R_X86_64_64 cannot be used against local symbol; recompile with -fPIC defined in /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib(ExceptionHandlerAsm.obj) referenced by /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/X64/ExceptionHandlerAsm.iii ExceptionHandlerAsm.obj:(.text+0x23) in archive /home/bcran/src/uefi/edk2/Build/OvmfX64/RELEASE_CLANGDWARF/X64/UefiCpuPkg/Library/CpuExceptionHandlerLib/SecPeiCpuExceptionHandlerLib/OUTPUT/SecPeiCpuExceptionHandlerLib.lib Thinking about it, it might actually be a problem with the FreeBSD system toolchain. On Linux, I get a different set of errors about redefining uint64_t etc.
