Bug ID: 8901
Summary: gcc failes to build if fortran is enabled
Product: buildroot
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned at buildroot.uclibc.org
Reporter: thijsvermeir at gmail.com
CC: buildroot at uclibc.org
Target Milestone: ---
When BR2_TOOLCHAIN_BUILDROOT_FORTRAN is enabled, gcc failes to build with this
error:
---
In file included from ../../../libgfortran/generated/any_l4.c:26:0:
../../../libgfortran/libgfortran.h:60:29: fatal error: quadmath_weak.h: No such
file or directory
# include "quadmath_weak.h"
^
compilation terminated.
---
A quick fix is to also enable BR2_TOOLCHAIN_BUILDROOT_WCHAR as this is enabling
libquadmath in `package/gcc/gcc.mk`.
This can be reproduces with a minimal qemu config:
---
BR2_x86_64=y
BR2_DL_DIR="$(TOPDIR)/../dl"
BR2_PACKAGE_HOST_LINUX_HEADERS_CUSTOM_4_5=y
BR2_TOOLCHAIN_BUILDROOT_FORTRAN=y
BR2_TARGET_GENERIC_GETTY_PORT="tty1"
BR2_SYSTEM_DHCP="eth0"
BR2_LINUX_KERNEL=y
BR2_LINUX_KERNEL_CUSTOM_VERSION=y
BR2_LINUX_KERNEL_CUSTOM_VERSION_VALUE="4.5"
BR2_LINUX_KERNEL_USE_CUSTOM_CONFIG=y
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="board/qemu/x86_64/linux-4.5.config"
BR2_TARGET_ROOTFS_EXT2=y
# BR2_TARGET_ROOTFS_TAR is not set
