Question

我正在尝试将external library called SVL (simple vector library)包含在c ++中。我遇到很多麻烦。我使用的是Mac OSX，库的README只有Windows的教程。

我做了

 make clean
 make

这创建了库文件libsvl.a和libsvl.dbg.a。我在READMEof the file中看到，它表示将其包含在svl/vec3.h左右，以用于不同的标头。但是，当我尝试这样做时，它不起作用，仍然说，

vertex.hh:9:10: fatal error: 'svl/Vec3.h' file not found
#include <svl/Vec3.h>
     ^
1 error generated.
vertex.cc:10:10: fatal error: 'svl/Vec3.h' file not found
#include <svl/Vec3.h>

你能告诉我我错过了什么吗？我可能需要更好地定义库的路径或执行不同的操作。

来自其他代码的库文件的相对路径为../svl-1.5/lib/libsvl.a

制作配置文件

#

# Mac OSX

CONFIG = OSX

# --- Compilation
----------------------------------------------------------
CC          =   cc
CXX         =   c++
LD          =   c++

SHARED_LIBS = off
USE_RANLIB = 1    

DEST        =   $(REACTOR)

config:
    @echo "configured for Mac OSX"

CL_EXT_FLAGS = -DCL_TMPL_INST -DCL_HAS_VSNPRINTF -DCL_POSIX_TIME
VL_EXT_FLAGS = -DVL_HAS_ABSF -DVL_USE_MEMCPY

运行make

的结果

cd src && /Applications/Xcode.app/Contents/Developer/usr/bin/make REACTOR=..
c++  -O2   \
            -c LibSVL.cpp -I../include -I/sw/include
c++  -O2   \
            -c Basics.cpp -I../include -I/sw/include
ar rcu libsvl.a LibSVL.o Basics.o
mkdir -p ../lib
mv libsvl.a ../lib
c++ -DDEBUG  -g  \
            -DVL_DEBUG \
            -c LibSVL.cpp -o LibSVL.do -I../include -I/sw/include
c++ -DDEBUG  -g  \
            -DVL_DEBUG \
            -c Basics.cpp -o Basics.do -I../include -I/sw/include

完成make个文件

#
# Main makefile for SVL distribution
#

# NOTE: To build multiple system libraries in AFS, make 'afs-setup' first.
# This will create the necessary architecture-dependent lib directories,
# and ensure that the config header goes there.

你必须执行

sudo make install
