编译Opengazer-0.1.2并获取vnl_cholesky.h错误

Question

在经历了这么多的麻烦之后，我终于能够安装VXL-1.14.0并编译了opengazer http://www.inference.phy.cam.ac.uk/opengazer/。我遵循了它的自述文件和mirkrules http://www.mirkules.com/opengazer/vxl_install_notes.txt的一个非常有用的注释，修改了opengazer的Makefile和相关文件(例如"PointTracker.h")。例如，在我的Makefile中，我将前几行改为如下(VxL头文件位于"/usr/local/include/ vxl“中，而共享库位于"/usr/local/lib”中，其中包含"libvnl_algo.so“和"libvnl.so")：

VXLDIR = /usr/local
VERSION = opengazer-0.1.2
CPPFLAGS = -Wall -g -O3
LINKER = -L$(VXLDIR)/lib -L/usr/local/lib -lm -ldl -lvnl -lmvl -lvnl_algo -lvgl -lgthread-2.0 

# change the following line if your vxl library is installed elsewhere
INCLUDES = $(foreach prefix,/usr/local/include $(VXLDIR)/include $(VXLDIR)/include/vxl, \
    $(foreach suffix,/core /vcl /contrib/oxl /core/vnl/algo,-I$(prefix)$(suffix)))

===

尽管如此，当我编译时，我得到的错误如下：

一般熟悉VXL、Opengazer或编译C库的人能告诉我这里到底是怎么回事吗？谢谢。

使用旧版本的gcc似乎可以解决这个问题：

sudo apt-get install g++-4.4

然后将Makefile中包含g++的行更改为g++-4.4。

如果之后遇到不明确的异常问题，请参考install notes。
