我已经编译了我的应用程序，但它未对齐 .bss 部分中的对象。为了比较建议，我在 CppUTest 框架内构建了相同的代码，使用相同的工具链，它显示填充在我的应用程序未对齐的同一位置。

应用地图文件（错位）：

CppUTest 框架编译（无错位）

下面，我展示了用于在 CppUTest 框架上编译的标志：

OS Linux
Compile C and C++ source with CPPFLAGS:
  -I
  ../../common/CppUTest/include/
  -Isrc
  -g
  -I
  ../../common/include
  -D
  AUTO_GEN_BUILD_TAG='0-g1db06ad'
  -D
  AUTO_GEN_FIRWMARE_VERSION='0.00-re8k-app-2013-09-16'
  -D
  SYSTEM_UNIT_TEST
  -DCPPUTEST_COMPILATION
  -Iinclude/CppUTestExt/CppUTestGMock
  -Iinclude/CppUTestExt/CppUTestGTest
  -Wall
  -include
  ../../common/CppUTest/include/CppUTest/MemoryLeakDetectorMallocMacros.h

Compile C++ source with CXXFLAGS:
  -g
  -Wall
  -include
  ../../common/CppUTest/include/CppUTest/MemoryLeakDetectorNewMacros.h

Compile C source with CFLAGS:
  -Wextra
  -pedantic
  -Wstrict-prototypes
  -g

Link with LDFLAGS:
  -Wl,-Map=app-tgt-test.map
  -g

Link with LD_LIBRARIES:
  ../../common/lib/libhal-tgt-test.a
  ../../common/lib/libchelper-tgt-test.a
  -L
  ../../common/shared-lib/
  -lzmq
  -lrt
  -lpthread
  -lm
  -lrt
  -lpthread
  -lm
  -lstdc++

Create libraries with ARFLAGS:
  rv

最后，这是生成未对齐可执行文件的构建步骤：

arm-arago-linux-gnueabi-gcc -I. -Isrc -g -I ../../common/include -D AUTO_GEN_BUILD_TAG='"0-g1db06ad"' -D AUTO_GEN_FIRWMARE_VERSION='"0.00-re8k-app-2013-09-16"'  -Wall src/main.c -c -o obj_tgt/main.o

arm-arago-linux-gnueabi-gcc  obj_tgt/main.o ../../common/lib/libhal-tgt.a ../../common/lib/libchelper-tgt.a -L ../../common/shared-lib/ -lzmq -lrt -lpthread -lm   -o app-tgt -Wl,-Map=app-tgt.map

请，欢迎任何帮助。我需要从我的代码中删除这种错位。
