通过一些研究后我可以看到,vivado是硬件开发IDE [因为它们提供了一个试用期 – 所以它是硬件开发,他们总是想要收费].
如果您使用的是Xilinx的标准SDK板,则应该预先配置所有内容.否则,硬件设计师会生成一个具有Microblaze的硬件设计.
从那时起,您可能必须使用petalinux来生成兼容的新引导,内核等图像.
您可能需要从源代码重建libstdc,但我会将其作为最后的手段.例如,不要打扰它,直到你有gdb工作并有测试结果.
开发指南显示了如何调用gdb(例如)：
在目标系统上：
gdbserver主机：1534 / bin / myapp
在开发系统上：
petalinux-utils –gdb myapp后跟目标远程192.168.0.10:1534
我已经使用注释对Makefile进行了一些编辑.我已经评论了一些非必要的选项.请注意,我正在使用=运算符逐渐构建CFLAGS / CXXFLAGS
这里的基本思想是以最小的“标准”偏差进行构建.仅添加经过验证的基本选项构建和测试.逐个添加选项[每次重建和测试],直到找到导致问题的选项.
然而,我确实怀疑 – 共同 – 是一个问题的根源.此外,在较小的程度上,我有点怀疑-Wl,– 根据需要
这些选项应该有效吗？当然,但xilinx / microblaze不是没有x86 ……
我添加了两个命令行make变量：
DEBUG – 使用gdb生成调试
VERBOSE – 显示构建过程的所有内容
例如,尝试make< whatever> DEBUG = 1 VERBOSE = 1
CC = microblazeel-xilinx-linux-gnu-gcc
CXX = microblazeel-xilinx-linux-gnu-g++
CPPFLAGS ?=
CMFLAGS += -Wall -Werror
CMFLAGS += -fmessage-length=0
# compile for gdb session
# NOTES:
# (1) -gdwarf-2 may or may not be the the right option for microblaze
# (2) based on doc for -feliminate-unused-debug* petalinux/microblaze may want
# stabs format
ifdef DEBUG
CMFLAGS += -gdwarf-2
CMFLAGS += -O0
# compile for normal build
#else
CMFLAGS += -O2
CMFLAGS += -feliminate-unused-debug-types
endif
# NOTE: I used to use "@" on commands,but now I leave it off -- debug or not
# sure it's "ugly" but you can get used to it pretty quickly--YMMV
ifndef VERBOSE
Q :=
else
###Q := @

endif
# let compiler/linker tell you _everything_:

ifdef VERBOSE
CMFLAGS += -v
LDFLAGS += -Wl,--verbose=2
endif
CMFLAGS += -fno-builtin
# NOTE: I'd _really_ leave this off as it may confuse c++ std as "<

# -fno-common)
###CMFLAGS += -fno-common
# NOTE: I'm also suspicIoUs of this a little bit because the c++ lib may have
# some "weak" symbols that the c library doesn't
###LDFLAGS += -Wl,--as-needed
# NOTE: this seems harmless enough,but you can comment it out to see if it
# helps
LDFLAGS += -Wl,--hash-style=gnu
# NOTE: an optimization only
ifndef DEBUG
LDFLAGS += -Wl,-O1
endif
CFLAGS += $(CMFLAGS)
CXXFLAGS += $(CMFLAGS)
# NOTES:
# (1) leave this off for now -- doesn't save _that_ much and adds complexity
# to the build
# (2) IMO,I _never_ use it and I erase/uninstall it on any system I
# administrate (or just ensure the build doesn't use it by removing it
# from $PATH)--YMMV
###XCCACHE = $(CCACHE)
# to compile
$(Q)$(XCCACHE) $(CXX) $(CPPFLAGS) $(CXXFLAGS) $(CFLAGS) $< -o "$@"
# to link
