[build] Allow for 32-bit and 64-bit versions of util/zbin

2025-05-06T11:11:02+00:00

Parsing ELF data is simpler if we don't have to build a single binary to handle both 32-bit and 64-bit ELF formats. Allow for separate 32-bit and 64-bit binaries built from util/zbin.c (as is already done for util/elf2efi.c). Signed-off-by: Michael Brown

[build] Work around -fPIE patched versions of gcc on all architectures

2021-02-04T02:53:25+00:00

Several distributions include versions of gcc that are patched to create position-independent executables by default. These have caused multiple problems over the years: see e.g. commits fe61f6d ("[build] Fix compilation when gcc is patched to default to -fPIE -Wl,-pie"), 5de1346 ("[build] Apply the "-fno-PIE -nopie" workaround only to i386 builds"), 7c395b0 ("[build] Use -no-pie on newer versions of gcc"), and decee20 ("[build] Disable position-independent code for ARM64 EFI builds"). The build system currently attempts to work around these mildly broken patched versions of gcc for the i386 and arm64 architectures. This misses the relatively obscure bin-x86_64-pcbios build platform, which turns out to also require the same workaround. Attempt to preempt the next such required workaround by moving the existing i386 version to apply to all platforms and all architectures, unless -fpie has been requested explicitly by another Makefile (as is done by arch/x86_64/Makefile.efi).

[build] Use -no-pie on newer versions of gcc

2017-06-14T11:33:16+00:00

Some distributions patch gcc to generate position independent executables by default. We currently include a workaround to check for this and to add -fno-PIE -nopie to CFLAGS if required. Newer patched versions of gcc require -fno-PIE -no-pie instead. Check for both variants. Reported-by: Nathan Rennie-Waldock Originally-fixed-by: Markos Chandras Signed-off-by: Michael Brown

[bios] Add bin-x86_64-pcbios build platform

2016-02-16T19:32:32+00:00

Move most arch/i386 files to arch/x86, and adjust the contents of the Makefiles and the include/bits/*.h headers to reflect the new locations. This patch makes no substantive code changes, as can be seen using a rename-aware diff (e.g. "git show -M5"). This patch does not make the pcbios platform functional for x86_64; it merely allows it to compile without errors. Signed-off-by: Michael Brown

[vmware] Expose GuestRPC mechanism in 64-bit builds

2016-01-05T17:20:36+00:00

The GuestRPC mechanism (used for VMWARE_SETTINGS and CONSOLE_VMWARE) does not use any real-mode code and so can be exposed in both 64-bit and 32-bit builds. Reported-by: Matthew Helton Signed-off-by: Michael Brown

[build] Search for ldlinux.c32 separately from isolinux.bin

2015-09-01T20:04:44+00:00

Some distributions (observed with Ubuntu 15.04) place ldlinux.c32 in a separate directory from isolinux.bin. Search for these files separately, and allow an alternative location of ldlinux.c32 to be provided via LDLINUX_C32=... on the make command line.

[build] Apply the "-fno-PIE -nopie" workaround only to i386 builds

2015-02-12T16:04:07+00:00

Hardened versions of gcc default to building position-independent code, which breaks our i386 build. Our build process therefore detects such platforms and automatically adds "-fno-PIE -nopie" to the gcc command line. On x86_64, we choose to build position-independent code (in order to reduce the final binary size and, in particular, the number of relocations required for UEFI binaries). The workaround therefore breaks the build process for x86_64 binaries on such platforms. Fix by moving the workaround to the i386-specific portion of the Makefile.
